Functional Description[1]

The CY7C1338G 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
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
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

CCoEn1tr o, ldeinppthu-tesxp AanDsSioCn,

Chip Enables ADSP, and

CE2 and CE3 , Burst ADV , Write Enables

BW[A:D], and inputs include

BWE , and Global the Output Enable

Write GW . OE and the

Asynchronous ZZ pin.

The CY7C1338G 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.

Addresses and chip enables are registered at rising edge of
clock when either Address Strobe Processor ADSP or Address Strobe Controller ADSC are active. Subsequent burst addresses can be internally generated as controlled by
