Description
Address Inputs: These inputs are registered into data RAMs and must
meet setup and hold times. The tag RAM addresses are not registered.
Address Status Processor: Initiates READ, WRITE, or chip deselect
cycle (Exception — chip deselect does not occur when ADSP is
asserted and CCS is high.
Burst Order Select: NC for interleaved burst counter. Tie to ground for
linear burst counter.
Byte Write Enable: To be used in future modules.
Cache Address Status: Initiates READ, WRITE, or chip deselect cycle.
Cache Burst Advance: Increments address count in accordance with
interleaved count style.
Chip Select: Active low chip enable for data RAMs.
Cache Output Enable: Active low asynchronous input.
Low — enables output buffers (DQ pins)
High — DQx pins are high impedance.
Clock: This signal registers the address, data in, and all control signals
except CG.
Cache Data Byte Write Enable: Active low write signal for data RAMs.
I/O Synchronous Data I/O:
Drives data out of data RAMs during READ cycles.
Stores data to data RAMs during WRITE cycles.
Input Expansion Chip Select.
Input
Global Write Enable: To be used in future modules.
Presence Detect: See Presence Detect Table.
— No Connection: Reserved for future use.
I/O Tag RAM I/O:
Drives data out during tag compare cycles.
Stores data to tag RAM during tag WRITE cycles.
Input Tag Write Enable: Active low write signal for tag RAMs.
Supply Power Supply: 5.0 V ± 5%.
Supply Power Supply: 3.3 V + 10%, – 5%.
Supply Ground.
— No Connection: There is no connection to the module.
