PRELIMINARY

1M x 36/2M x 18/512K x 72 Flow-Thru SRAM

inputs are gated by registers controlled by a positive-

edge-triggered clock input (CLK). The synchronous inputs

Features

•Supports 133-MHz bus operations

•1M x 36/2M x18/512K x 72 common I/O

•Fast clock-to-output times

— 5.5 ns (for 150-MHz device)

— 6.5 ns (for 133-MHz device)

— 7.5 ns (for 117-MHz device)

include all addresses, all data inputs, address-pipelining Chip

Enable (CE), Burst Control Inputs (ADSC, ADSP, and ADV),

Write Enables (BWa, BWb, BWc, BWd,BWe,BW_f,BW_gand

BW_h, BWE), and Global Write (GW).

Asynchronous inputs include the Output Enable (OE) and

Burst Mode Control (MODE). The data outputs (Q), enabled

by OE, are also asynchronous.

• Single 2.5V –5% and +5% power supply V_DD

• Separate V_DDQfor 2.5V or 1.8V I/O

• Byte Write Enable and Global Write control

• Burst capability–linear or interleaved burst order

Addresses and chip enables are registered with either

Address Status Processor (ADSP) or address status controller

(ADSC) input pins. Subsequent burst addresses can be inter-

nally generated as controlled by the Burst Advance Pin (ADV).

• Automatic power down available using ZZ mode or CE

deselect

• JTAG boundary scan for BGA packaging version

• Available in 119-ball bump BGA, 165-ball FBGA, and

100-pin TQFP packages (CY7C1441V25 and

CY7C1443V25). 209 FBGA package for CY7C1447V25.

Address, data inputs, and Write controls are registered on-chip

to initiate self-timed Write cycle. Write cycles can be one to

four bytes wide as controlled by the Write control inputs.

Individual byte Write allows individual byte to be written. BWa

controls DQ1–DQ8 and DP1. BWb controls DQ9–DQ16 and

DP2. BWc controls DQ17–DQ24and DP3. BWd controls

DQ25–DQ32 and DP4. BWe controls DQ33–DQ40 and DP5.

BWf controls DQ41–DQ48 and DP6. BWg controls

DQ49–DQ56 and DP7. BWh controls DQ57–DQ64 and DP8.

BWa, BWb BWc, BWd, BWe, BWf, BWg, and BWh can be

active only with BWE LOW. GW LOW causes all bytes to be

written. Write pass-thru capability allows written data available

at the output for the immediately next Read cycle. This device

also incorporates pipelined enable circuit for easy depth

expansion without penalizing system performance.

Functional Description

The Cypress Synchronous Burst SRAM family employs

high-speed, low-power CMOS designs using advanced

single-layer polysilicon, triple-layer metal technology. Each

memory cell consists of six transistors.

The CY7C1441V25/CY7C1443V25/CY7C1447V25 SRAMs

integrate 1,048,576 × 36/2,097,152 × 18/524,288 × 72 SRAM

cells with advanced synchronous peripheral circuitry and a

two-bit counter for internal burst operation. All synchronous

All inputs and outputs of the CY7C1441V25/ CY7C1443V25/

CY7C1447V25 are JEDEC-standard JESD8-5 compatible.
