CY7C1041AV33/

GVT73256A16

PRELIMINARY

256K x 16 Static RAM

Functional Description

Features

• Fast access times: 10, 12 ns

The CY7C1049AV33\GVT73512A8 is organized as a 262,144

x 16 SRAM using a four-transistor memory cell with a high-per-

formance, silicon gate, low-power CMOS process. Cypress

SRAMs are fabricated using double-layer polysilicon, dou-

ble-layer metal technology.

• Fast OE access times: 5, 6, and 7 ns

• Single +3.3V ±0.3V power supply

• Fully static—no clock or timing strobes necessary

• All inputs and outputs are TTL-compatible

• Three state outputs

• Center power and ground pins for greater noise

immunity

• Easy memory expansion with CE and OE options

• Automatic CE power-down

This device offers center power and ground pins for improved

performance and noise immunity. Static design eliminates the

need for external clocks or timing strobes. For increased sys-

tem flexibility and eliminating bus contention problems, this de-

vice offers Chip Enable (CE), separate Byte Enable controls

(BLE and BHE) and Output Enable (OE) with this organization.

• High-performance, low power consumption, CMOS

double-poly, double-metal process

• Packaged in 44-pin, 400-mil SOJ and 44-pin, 400-mil

TSOP

The device offers a low-power standby mode when chip is not

selected. This allows system designers to meet low standby

power requirements.
