IS27HC010 IS27HC010 131,072 x 8 HIGH-SPEED CMOS EPROM ISSI JULY 1997 ISSI (R) (R) FEATURES * Fast read access time: 30 ns * Pin compatible with the IS27C010 * High-speed write programming -- Typically less than 30 seconds * Industrial and commercial temperature ranges available * 10% power supply tolerance * JEDEC-approved pinout * Standard 32-pin DIP, PLCC, and TSOP packages DESCRIPTION The ISSI IS27HC010 is an ultra-high-speed 1 megabit (128Kword by 8-bit) Ultraviolet Erasable CMOS Programmable Read-Only Memory. It utilizes the standard JEDEC pinout making it functionally compatible with the IS27C010, but with significantly faster access capability. This superior random access capability results from a focused high-speed design. This offers users bipolar speeds with higher density, lower cost, and proven reliability. The device is ideal for use with the faster processors. Designers may take full advantage of high-speed digital signal processors and microprocessors by allowing code to be executed at full speed directly out of EPROM. Typical applications include laser printers, switching networks, graphics, workstations, high-speed modems, and digital signal processing. The IS27HC010 uses ISSI's write programming algorithm which allows the entire chip to be programmed in typically less than 30 seconds. This product is available inOne-Time Programmable (OTP) PDIP, PLCC, and TSOP packages over commercial and industrial temperature ranges.

EP009-1F 07/18/97 IS27HC010 FUNCTIONAL DESCRIPTION Erasing the IS27HC010 In order to clear all locations of their programmed contents, it is necessary to expose the IS27HC010 to an ultraviolet light source. A dosage of 30W - sec/cm2 is required to completely erase the IS27HC010. This dosage can be obtained by exposure to an ultraviolet lamp-wavelength of 2537 Angstroms (A)--with intensity of 12,000 W/cm2 for 30 to 40 minutes. The IS27HC010 should be directly under and about one inch from the source and all filters should be removed from the UV light source prior to erasure. It is important to note that the IS27HC010, and similar devices, will erase with light sources having wavelengths shorter than 4000A. The exposure to fluorescent light and sunlight will eventually erase the IS27HC010 and exposure to them should be prevented to realize maximum system reliability. If used in such an environment, the package window should be covered by an opaque label or substance. Programming the IS27HC010 Upon delivery, or after each erasure, the IS27HC010 has 1,048,576 bits in the "ONE", or HIGH state. "ZEROs" are loaded into the IS27HC010 through the procedure of programming. The programming mode is entered when 12.75 0.25V is applied to the VPP pin, VCC = 6.25V, CE and PGM is at VIL, and OE is at VIH. For programming, the data to be programmed is applied eight bits in parallel to the data output pins. The write programming algorithm reduces programming time by using 100 s programming pulses followed by a byte verification to determine whether the byte has been successfully programmed. If the data does not verify, an additional pulse is applied for a maximum of 25 pulses. This process is repeated while sequencing through each address of the EPROM. The write programming algorithm programs and verifies at VCC = 6.25V and VPP = 12.75V. After the final address is completed, all byte are compared to the original data with VCC = 5.25V. Program Inhibit Programming of multiple IS27HC010s in parallel with different data is also easily accomplished. Except for CE, all like inputs of the parallel IS27HC010 may be common. A TTL low-level program pulse applied to an IS27HC010 CE input with VPP = 12.75 0.25V, PGM LOW and OE HIGH will program that IS27HC010. A high-level CE input inhibits the other IS27HC010 from being programmed. ISSI (R) Program Verify A verify should be performed on the programmed bits to determine that they were correctly programmed. The verify should be performed with OE and CE at VIL, PGM at VIH, and VPP between 12.5V and 13.0V. Auto Select Mode The auto select mode allows the reading out of a binary code from an EPROM that will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional in the 25C 5C ambient temperature range that is required when programming the IS27HC010. To activate this mode, the programming equipment must force 12.0 0.5V on address line A9 of the IS27HC010. Two identifier bytes may then be sequenced from the device outputs by toggling address line A0 from VIL to VIH. All other address lines must be held at VIL during auto select mode. Byte 0 (A0 = VIL) represents the manufacturer code, and byte 1 (A0 = VIH), the device identifier code. For the IS27HC010, these two identifier bytes are given in the Mode Select table. All identifiers manufacturer and device codes will possess odd parity, with the MSB (DQ7) defined as the parity bit. Read Mode The IS27HC010 has two control functions, both of which must be logically satisfied in order to obtain data at the outputs. Chip Enable (CE) is the power control and should be used for device selection. Assuming that addresses are stable, address access time (tACC) is equal to the delay from CE to output (tCE). Output Enable (OE) is the output control and should be used to get data to the output pins, independent of device selection. Data is available at the outputs tOE after the falling edge of OE assuming that CE has been LOW and addresses have been stable for at least tACC - tOE. Standby Mode The IS27HC010 has a standby mode which reduces the maximum VCC active current. It is placed in standby mode when CE is at VIH. The amount of current drawn in standby mode depends on the frequency and the number of address pins switching. The IS27HC010 is specified with 50% of the address lines toggling at 10 MHz. A reduction of the frequency or quantity of address lines toggling will significantly reduce the actual standby current. Integrated Silicon Solution, Inc. EP009-1F 07/18/97 3 IS27HC010 Output OR-Tieing To accommodate multiple memory connections, a twoline control function is provided to allow for: 1. Low memory power dissipation, and 2. Assurance that output bus contention will not occur. It is recommended that CE be decoded and used as the primary device-selecting function, while OE be made a common connection to all devices in the array and connected to the READ line from the system control bus. This assures that all deselected memory devices are in their low-power standby mode and that the output pins are only active when data is desired from a particular memory device. ISSI (R) System Applications During the switch between active and standby conditions, transient current peaks are produced on the rising and falling edges of Chip Enable. The magnitude of these transient current peaks is dependent on the output capacitance loading of the device at a minimum, a 0.1 F ceramic capacitor (high-frequency, low inherent inductance) should be used on each device between VCC and GND to minimize transient effects. In addition, to overcome the voltage drop caused by the inductive effects of the printed circuit board traces on EPROM arrays, a 4.7 F bulk electrolytic capacitor should be used between VCC and GND for each eight devices. The location of the capacitor should be close to where the power supply is connected to the array.
