Functional Description

[1]

The CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F is a

3.3V, 512K x 36 and 1M x 18 synchronous flow through

SRAMs, designed to interface with high-speed

microprocessors with minimum glue logic. Maximum access

delay from clock rise is 6.5 ns (133 MHz version). A 2-bit

on-chip counter captures the first address in a burst and

increments the address automatically 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

and CE

[2]

), 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 CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F

allows 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 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 CY7C1381D/CY7C1383D/CY7C1381F/CY7C1383F

operates from a +3.3V core power supply while all outputs

operate with a +2.5V or +3.3V supply. All inputs and outputs

are JEDEC-standard and JESD8-5-compatible.
