PRELIMINARY

CY7C1347

128K x 36 Synchronous-Pipelined Cache RAM

Features

Functional Description

• Low (1.65 mW) standby power (f=0, L version)

The CY7C1347 is a 3.3V 128K by 36 synchronous-pipelined

cache SRAM designed to support zero wait state secondary

cache with minimal glue logic.

• Supports 100-MHz bus for Pentium® and PowerPC™

operations with zero wait states

All synchronous inputs pass through input registers controlled

by the rising edge of the clock. All data outputs pass through

output registers controlled by the rising edge of the clock. Max-

imum access delay from the clock rise is 3.5 ns (166-MHz

device). A 2-bit on-chip wraparound burst counter captures the

first address in a burst sequence and automatically increments

the address for the rest of the burst access.

• Fully registered inputs and outputs for pipelined

operation

• 128K x 36 common I/O architecture

• Single 3.3V power supply

• Fast clock-to-output times

— 3.5 ns (for 166-MHz device)

— 4.0 ns (for 133-MHz device)

— 4.5 ns (for 117-MHz device)

— 5.5 ns (for 100-MHz device)

The CY7C1347 supports either the interleaved burst se-

quence used by the Intel Pentium processor or a linear burst

sequence used by processors such as the PowerPC. The burst

sequence is selected through the MODE pin. Accesses can be

initiated by asserting either the processor address strobe

(ADSP) or the controller address strobe (ADSC) at clock rise.

Address advancement through the burst sequence is con-

trolled by the ADV input.

• User-selectable burst counter supporting Intel®

Pentium interleaved or linear burst sequences

• Separate processor and controller address strobes

• Synchronous self-timed writes

Byte write operations are qualified with the four Byte Write

Select (BW

) inputs. A Global Write Enable (GW) overrides

[3:0]

• Asynchronous output enable

the byte write inputs and writes data to all four bytes. All writes

are conducted with on-chip synchronous self-timed write cir-

cuitry.

• JEDEC-standard 100-pin TQFP pinout

• “ZZ” Sleep Mode option and Stop Clock option

Three synchronous chip selects (CE , CE , CE ) and an asyn-

chronous output enable (OE) provide for easy bank selection

and output three-state control. In order to provide proper data

during depth expansion, OE is masked during the first clock of

a read cycle when emerging from a deselected state.
