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
Logic Block Diagram
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
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
(CE
), depth-expansion Chip Enables (CE
2
and
CE
), Burst
Control inputs (ADSC, ADSP, and ADV), Write Enables
(BW
, and BWE), and Global Write (GW). Asynchronous
inputs include the Output Enable (OE) and the ZZ pin.
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.
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
the Advance pin (ADV).
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.
