CY7C1347

128K x 36 Synchronous-Pipelined Cache RAM

The CY7C1347 I/O pins can operate at either the 2.5V or the

3.3V level, the I/O pins are 3.3V tolerant when V_DDQ= 2.5V.

Features

• Supports 100-MHz bus for Pentium and PowerPC™

operations with zero wait states

• Fully registered inputs and outputs for pipelined oper-

ation

• 128K by 36 common I/O architecture

• 3.3V core power supply

• 2.5V/3.3V I/O operation

• Fast clock-to-output times

— 3.5 ns (for 166-MHz device)

— 4.0 ns (for 133-MHz device)

— 5.5 ns (for 100-MHz device)

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).

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 controlled by the ADV input. 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.

• User-selectable burst counter supporting Intel Pen-

tium interleaved or linear burst sequences

• Separate processor and controller address strobes

• Synchronous self-timed writes

• Asynchronous output enable

• JEDEC-standard 100 TQFP pinout

• “ZZ” Sleep Mode option and Stop Clock option

• Available in Industrial and Commercial Temperature

ranges

Byte write operations are qualified with the four Byte Write

Select (BW_[3:0]) inputs. A Global Write Enable (GW) overrides

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

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

cuitry.

Three synchronous Chip Selects (CE₁, CE₂, CE₃) and an

asynchronous Output Enable (OE) provide for easy bank se-

lection and output three-state control. In order to provide prop-

er data during depth expansion, OE is masked during the first

clock of a read cycle when emerging from a deselected state.

Functional Description

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.
