4-Mb (128K x 32) Flow-Through Sync SRAM

6.5 ns (133-MHz version). A 2-bit on-chip counter captures the

first address in a burst and increments the address automati-

cally for the rest of the burst access. All synchronous inputs

Features

• 128K X 32 common I/O

• 3.3V –5% and +10% core power supply (V_DD

are gated by registers controlled by a positive-edge-triggered

Clock Input (CLK). The synchronous inputs include all

addresses, all data inputs, address-pipelining Chip Enable

)

• 2.5V or 3.3V I/O supply (V_DDQ

• Fast clock-to-output times

— 6.5 ns (133-MHz version)

— 7.5 ns (117-MHz version)

— 8.0 ns (100-MHz version)

The CY7C1338F allows either interleaved or linear burst

sequences, selected by the MODE input pin. A HIGH selects

an interleaved burst sequence, while a LOW selects a linear

burst sequence. Burst accesses can be initiated with the

Processor Address Strobe (ADSP) or the cache Controller

Address Strobe (ADSC) inputs. Address advancement is

controlled by the Address Advancement (ADV) input.

• Provide high-performance 2-1-1-1 access rate

• User-selectable burst counter supporting Intel^

Functional Description^[1]

The CY7C1338F is a 131,072 x 32 synchronous cache RAM

designed to interface with high-speed microprocessors with

minimum glue logic. Maximum access delay from clock rise is

The CY7C1338F operates from a +3.3V core power supply

while all outputs may operate with either a +2.5 or +3.3V

supply. All inputs and outputs are JEDEC-standard

JESD8-5-compatible.
