| Freescale Semiconductor Data Sheet: Technical Data Document Number: MCF51CN128 Rev. 4, 5/2009 MCF51CN128 MCF51CN128 ColdFire Microcontroller Cover: MCF51CN128 The MCF51CN128 device is a low-cost, low-power, high-performance 32-bit ColdFire V1 microcontroller (MCU) featuring 10/100 BASE-T/TX fast ethernet controller (FEC), media independent interface (MII) to connect an external physical transceiver (PHY), and multi-function external bus interface. MCF51CN128 also has multiple communication interfaces for various ethernet gateway applications. MCF51CN128 is the first ColdFire V1 device to incorporate ethernet and external bus interface along with new features to minimize power consumption and increase functionality in low-power modes. The MCF51CN128 features the following functional units: * 32-bit ColdFire V1 Central Processing Unit (CPU) - Up to 50.33 MHz ColdFire CPU from 3.6 V to 3.0 V, up to 40 MHz CPU from 3.0 V to 2.1 V, and up to 20 MHz CPU from 2.1 V to 1.8 V across temperature range of -40 C to 85 C - Provides 0.94 Dhrystone 2.1 MIPS per MHz performance when running from internal RAM (0.76 DMIPS/MHz from flash) - ColdFire Instruction Set Revision C (ISA_C) - Support for up to 45 peripheral interrupt requests and 7 software interrupts * On-Chip Memory - 128 KB Flash, 24 KB RAM - Flash read/program/erase over full operating voltage and temperature - On-chip memory aliased to create a contiguous memory space with off-chip memory - Security circuitry to prevent unauthorized access to Peripherals, RAM, and flash contents * Ethernet - FEC--10/100 BASE-T/TX, bus-mastering fast ethernet controller with direct memory access (DMA); supports half or full duplex; operation is limited to 3.0 V to 3.6 V 80 LQFP 14 mm x 14 mm 64 LQFP 10 mm x 10 mm 48 QFN 7 mm x 7 mm - MII--media independent interface to connect ethernet controller to external PHY; includes output clock for external PHY * External Bus - Mini-FlexBus--Multi-function external bus interface; supports up to 1 MB memories, gate-array logic, simple slave device or glueless interfaces to standard chip-selected asynchronous memories - Programmable options: access time per chip select, burst and burst-inhibited transfers per chip select, transfer direction, and address setup and hold times * Power-Saving Modes - Two low-power stop modes, one of which allows limited use of some peripherals (ADC, KBI, RTC) - Reduced-power wait mode shuts off CPU and allows full use of all peripherals; FEC can remain active and conduct DMA transfers to RAM and assert an interrupt to wake up the CPU upon completion - Low-power run and wait modes allow peripherals to run while the voltage regulator is in standby - Peripheral clock enable register can disable clocks to unused modules, thereby reducing currents - Low-power external oscillator that can be used in stop3 mode to provide accurate clock source to active peripherals - Low-power real-time counter for use in run, wait, and stop modes with internal and external clock sources - 6 s typical wake-up time from stop3 mode - Pins and clocks to peripherals not available in smaller packages are automatically disabled for reduced current consumption; no user interaction is needed * Clock Source Options - Oscillator (XOSC) -- Loop-control pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz or 1 MHz to 25 MHz - Multi-Purpose Clock Generator (MCG) -- Flexible clock source module with either frequency-locked-loop (FLL) or phase-lock loop (PLL) clock options. FLL can be controlled by internal or external reference and Freescale reserves the right to change the detail specifications as may be required to permit improvements in the design of its products. (c) Freescale Semiconductor, Inc., 2009. All rights reserved. * * * * includes precision trimming of internal reference, allowing 0.2% resolution and 2% deviation over temperature and voltage.

When PTD6 is set as RGPIO output, and "1" is driven to PTD6 via RGPIO function, a read of register RGPIODATA6 always returns a "0" because V1 RGPIO design looks for IO enable when the return value of RGPIO function reads data. As PTD6 is set to RGPIO output only, it returns "0" always to RGPIODATA6, athough PTD6 pin is driven to high. 3 3.1 Electrical Characteristics Introduction This section contains electrical and timing specifications for the MCF51CN128 series of microcontrollers available at the time of publication. MCF51CN128 ColdFire Microcontroller Data Sheet, Rev. 4 Freescale Semiconductor 11 Electrical Characteristics 3.2 Parameter Classification Table 3. Parameter Classifications P C T D These parameters are guaranteed during production testing on each individual device. These parameters are achieved by the design characterization by measuring a statistically relevant sample size across process variations. These parameters are achieved by design characterization on a small sample size from typical devices under typical conditions unless otherwise noted. All values shown in the typical column are within this category. These parameters are derived mainly from simulations. The electrical parameters shown in this supplement are guaranteed by various methods. To give the customer a better understanding the following classification is used and the parameters are tagged accordingly in the tables where appropriate: NOTE The classification is shown in the column labeled "C" in the parameter tables where appropriate. 3.3 Absolute Maximum Ratings Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the limits specified in Table 4 may affect device reliability or cause permanent damage to the device. For functional operating conditions, refer to the remaining tables in this section. This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for instance, either VSS or VDD) or the programmable pull-up resistor associated with the pin is enabled. Table 4. Absolute Maximum Ratings Rating Supply voltage Maximum current into VDD Digital input voltage Instantaneous maximum current Single pin limit (applies to all port pins)1, 2, 3 Storage temperature range 1 Symbol VDD IDD VIn ID Tstg Value -0.3 to +3.8 120 -0.3 to VDD + 0.3 25 -55 to 150 Unit V mA V mA C Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive (VDD) and negative (VSS) clamp voltages, then use the larger of the two resistance values. 2 All functional non-supply pins are internally clamped to V SS and VDD. 3 Power supply must maintain regulation within operating V DD range during instantaneous and operating maximum current conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may flow out of VDD and could result in external power supply going out of regulation. Ensure external VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power. Examples are: if no system clock is present, or if the clock rate is very low (which would reduce overall power consumption). MCF51CN128 ColdFire Microcontroller Data Sheet, Rev. 4 12 Freescale Semiconductor Electrical Characteristics 3.4 Thermal Characteristics This section provides information about operating temperature range, power dissipation, and package thermal resistance. Power dissipation on I/O pins is usually small compared to the power dissipation in on-chip logic and voltage regulator circuits, and it is user-determined rather than being controlled by the MCU design. To take PI/O into account in power calculations, determine the difference between actual pin voltage and VSS or VDD and multiply by the pin current for each I/O pin. Except in cases of unusually high pin current (heavy loads), the difference between pin voltage and VSS or VDD will be very small. Table 5.

The average chip-junction temperature (TJ) in C can be obtained from: TJ = TA + (PD x JA) where: TA = Ambient temperature, C JA = Package thermal resistance, junction-to-ambient, C/W PD = Pint + PI/O Pint = IDD x VDD, Watts -- chip internal power PI/O = Power dissipation on input and output pins -- user determined For most applications, PI/O << Pint and can be neglected. An approximate relationship between PD and TJ (if PI/O is neglected) is: PD = K / (TJ + 273C) Solving Equation 1 and Equation 2 for K gives: K = PD x (TA + 273C) + JA x (PD)2 Eqn. 3 Eqn. 2 Eqn. 1 where K is a constant pertaining to the particular part. K can be determined from equation 3 by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving Equation 1 and Equation 2 iteratively for any value of TA. MCF51CN128 ColdFire Microcontroller Data Sheet, Rev. 4 Freescale Semiconductor 13 Electrical Characteristics 3.5 ESD Protection and Latch-Up Immunity Although damage from electrostatic discharge (ESD) is much less common on these devices than on early CMOS circuits, normal handling precautions should be used to avoid exposure to static discharge. Qualification tests are performed to ensure that these devices can withstand exposure to reasonable levels of static without suffering any permanent damage. All ESD testing is in conformity with AEC-Q100 Stress Test Qualification for Automotive Grade Integrated Circuits. During the device qualification ESD stresses were performed for the human body model (HBM), the machine model (MM) and the charge device model (CDM). A device is defined as a failure if after exposure to ESD pulses the device no longer meets the device specification. Complete DC parametric and functional testing is performed per the applicable device specification at room temperature followed by hot temperature, unless specified otherwise in the device specification.

This specification applies to any time the FLL reference source or reference divider is changed, trim value changed or changing from FLL disabled (BLPE, BLPI) to FLL enabled (FEI, FEE, FBE, FBI). If a crystal/resonator is being used as the reference, this specification assumes it is already running. 3 This specification applies to any time the PLL VCO divider or reference divider is changed, or changing from PLL disabled (BLPE, BLPI) to PLL enabled (PBE, PEE). If a crystal/resonator is being used as the reference, this specification assumes it is already running. 4 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fBUS. Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise injected into the FLL circuitry via VDD and VSS and variation in crystal oscillator frequency increase the CJitter percentage for a given interval. 5 Below D lock minimum, the MCG is guaranteed to enter lock. Above Dlock maximum, the MCG does not enter lock. But if the MCG is already in lock, then the MCG may stay in lock. 6 Below Dunl minimum, the MCG does not exit lock if already in lock. Above Dunl maximum, the MCG is guaranteed to exit lock. MCF51CN128 ColdFire Microcontroller Data Sheet, Rev. 4 22 Freescale Semiconductor Electrical Characteristics 3.10 Mini-FlexBus Timing Specifications A multi-function external bus interface called Mini-FlexBus is provided with basic functionality to interface to slave-only devices up to a maximum bus frequency of 25.1666 MHz. It can be directly connected to asynchronous or synchronous devices such as external boot ROMs, flash memories, gate-array logic, or other simple target (slave) devices with little or no additional circuitry. For asynchronous devices a simple chip-select based interface can be used. All processor bus timings are synchronous; that is, input setup/hold and output delay are given in respect to the rising edge of a reference clock, MB_CLK. The MB_CLK frequency is half the internal system bus frequency. The following timing numbers indicate when data is latched or driven onto the external bus, relative to the Mini-FlexBus output clock (MB_CLK). All other timing relationships can be derived from these values. Table 12.

This is the shortest pulse that is guaranteed to be recognized as a reset or interrupt pin request. Shorter pulses are not guaranteed to override reset requests from internal sources. 3 To enter BDM mode following a POR, BKGD/MS should be held low during the power-up and for a hold time of t MSH after VDD rises above VLVD. 4 This is the minimum assertion time in which the interrupt may be recognized. The correct protocol is to assert the interrupt request until it is explicitly negated by the interrupt service routine. 5 Timing is shown with respect to 20% V DD and 80% VDD levels.

This information supplied for calculating approximate time to program and erase. 3 The program and erase currents are additional to the standard run IDD. These values are measured at room temperatures with VDD = 3.3 V, bus frequency = 8.0 MHz. 4 Typical endurance for flash was evaluated for this product family on the HC9S12Dx64. For additional information on how Freescale defines typical endurance, please refer to Engineering Bulletin EB619, Typical Endurance for Nonvolatile Memory. 5 Typical data retention values are based on intrinsic capability of the technology measured at high temperature and de-rated to 25 C using the Arrhenius equation. For additional information on how Freescale defines typical data retention, refer to Engineering Bulletin EB618, Typical Data Retention for Nonvolatile Memory. 3.13 EMC Performance Electromagnetic compatibility (EMC) performance is highly dependent on the environment in which the MCU resides. Board design and layout, circuit topology choices, location and characteristics of external components as well as MCU software operation all play a significant role in EMC performance. The system designer should consult Freescale applications notes such as AN2321, AN1050, AN1263, AN2764, and AN1259 for advice and guidance specifically targeted at optimizing EMC performance.
