V360EPC Rev. A0 / A1
LOCAL BUS TO PCI BRIDGE FOR DE-MULTIPLEXED A/D PROCESSORS
* Glueless interface to i960Cx/Hx and AMD29030/40 processors * Configurable for primary master, bus master or target operation. * Type 0 and type 1 configuration cycles. * Up to 1Kbyte burst access on PCI or local. * Large, 640-byte FIFOs using V3's unique DYNAMIC BANDWIDTH ALLOCATIONTM architecture * 64-byte read FIFO per aperture. * Enhanced support for 8/16-bit local bus devices with programmable region sizes. * 3.3 volt support * Dual bi-directional address space remapping * Fully compliant with PCI 2.1 specification V360EPC provides the highest performance, most flexible, and most economical method to directly connect i960Cx/Hx or AMD2930/40 processors to the PCI bus. As a generic solution for 32-bit de-multiplexed local bus applications, V360EPC is also a suitable candidate for a variety of high-performance applications based on Motorola, IBM, DEC and Hitachi embedded processors - where a minimal amount of glue logic is needed. V360EPC is the second generation of V3's I2O ready PCI bridges - fully backward compatible with V962PBC and V292PBC Rev B2 devices and is supporting powerful features like Hot Swap and DMA chaining. The PCI bus can be run at full 33MHz, independent of local bus clock rate. The overall throughput of the system is dramatically improved by increasing the FIFO
* On-the-fly byte order (endian) conversion * I2O ATU and messaging unit including hardware controlled circular queues * 2 channel DMA controller plus multiprocessor DMA chaining and demand mode DMA * Hot swapping capability * 16 8-bit bi-directional mailbox registers with doorbell interrupts * Flexible PCI and local interrupt management * Optional power-on serial EEPROM initialization * 33MHz and 50MHz local bus versions * Industrials Temperature Grade -40 to +85'C * Low cost 160-pin EIAJ PQFP package
d e p t h s a n d u t i l i z i n g th e u n i q u e D Y N A M I C BANDWIDTH ALLOCATIONTM architecture. Access to the PCI bus can be performed through two programmable address apertures. Two more apertures are provided for PCI-to-local bus accesses. There are 64-bytes of read FIFOs in each direction, 32-bytes dedicated for each aperture. Two high-performance DMA channels with chaining and demand mode capabilities provide a powerful data transfer engine for bulk data transfers. Mailbox registers and flexible PCI interrupt controllers are also included to provide a simple mechanism to emulate PCI device control ports. The part is available in 160-pin low cost PQFP packages.

Table 3: Signal Descriptions
PCI Bus Interface Signal AD[31:0] C/BE[3:0] PAR FRAME Type PCI I/O PCI I/O PCI I/O PCI I/O Ra Z Z Z Z Description Address and data, multiplexed on the same pins. Bus Command and Byte Enables, multiplexed on the same pins. Parity represents even parity across AD[31:0] and C/BE[3:0]. Cycle Frame indicates the beginning and burst length of an access. Initiator Ready indicates the initiating agent's (bus master's) ability to complete the current data phase of the transaction. Target Ready indicates the target agent's (selected device's) ability to complete the current data phase of the transaction. Stop indicates the current target is requesting the master to stop the current transaction (retry or disconnect). Device Select, when actively driven by a target, indicates the driving device has decoded its address as the target of the current access. As an input to the initiator, DEVSEL indicates whether any device on the bus has been selected. Initialization Device Select is used as a chip select during configuration read and write transactions. It must be driven high in order to access the chip's internal configuration space. Z Request indicates to the arbiter that this agent requests use of the bus. Grant indicates to the agent that access to the bus has been granted. PCLK provides timing for all transactions on the PCI bus. Acts as an input when RDIR is high, an output when RDIR is low. As an input it is asserted low to bring all internal EPC operation to a reset state. Parity Error is used to report data parity errors during all PCI transactions except a Special Cycle. System Error is used to report address parity errors, data parity errors on the Special Cycle command, or any other system error where the result will be catastrophic. Level-sensitive interrupt requests may be received or generated.

Test Mode Pins
Several device pins are used during manufacturing test to put the V360EPC device into various test modes. These pins must be maintained at proper levels during reset to insure proper operation. This is typically handled through pull-up or pull-down resistors (typically 1K to 10K) on the signal pins if they are not guaranteed to be at the proper level during reset. Table 4 below shows the reset states for test mode pins:

Notes: 1. Input leakage currents include high impedance output leakage for all bi-directional buffers with tri-state outputs. 2. Signals without pull-up resistors have greater than 3mA low output current. Signals requiring pull resistors have greater than 6mA output current. The latter include FRAME, TRDY, IRDY, STOP, SERR, PERR. 3. Absolute maximum pin capacitance for a PCI unit is 10pF (except for CLK). 4. Lower capacitance on this input-only pin allows for non-resistive coupling to AD[xx].

Notes: 1. Refer to the V/I curves in Section 4.2.1 of the PCI Specification. This specification does not apply to CLK and RST which are system outputs. "Switching Current High" specifications are not relevant to open drain outputs such as SERR and INTA-INTD. 2. Note that this segment of the minimum current curve is drawn from the AC drive point directly to the DC drive point rather than toward the voltage rail (as it does in the pull-down curve). This difference is intended to allow for an optional N-channel pull-up. 3. Maximum current requirements are met as drivers pull beyond the first step voltage (AC drive point). Equations defining these maximums (A and B) are provided with the respective V/I curves given in the PCI Spec. The equation defined maxima is met by design. 4. The minimum slew rate (slowest signal edge) is met by the PCI drivers. The maximum slew rate (fastest signal edge) is a guideline. Motherboard designers must bear in mind that rise and fall times faster than this maximum guideline could occur, and should ensure that signal integrity modeling accounts for this. Equation A: IOH = 11.9*(VOUT - 5.25V)*(VOUT + 2.45V) for VCC > VOUT > 3.1V Equation B: IOL = 78.5*VOUT(4.4V - V OUT) for 0V < VOUT < 0.71V
