256K x 32 HIGH-SPEED ASYNCHRONOUS

CMOS STATIC RAM WITH 3.3V SUPPLY

PRELIMINARY INFORMATION

APRIL 2008

FEATURES

DESCRIPTION

The ISSI IS61WV25632Axx/Bxx and IS64WV25632Bxx

are high-speed, 8M-bit static RAMs organized as 256K

words by 32 bits. It is fabricated using ISSI's high-per-

formance CMOS technology. This highly reliable process

coupled with innovative circuit design techniques, yields

high-performance and low power consumption devices.

• High-speed access times:

8, 10, 20 ns

• High-performance, low-power CMOS process

• Multiple center power and ground pins for

greater noise immunity

• Easy memory expansion with CE and OE op-

tions

• CE power-down

• Fully static operation: no clock or refresh

When CE is HIGH (deselected), the device assumes

a standby mode at which the power dissipation can be

reduced down with CMOS input levels.

required

Easymemory expansion is provided by using Chip Enable

and Output Enable inputs, CE and OE. The active LOW

Write Enable (WE) controls both writing and reading of

the memory.

• TTL compatible inputs and outputs

• Single power supply

V^{d d}1.65V to 2.2V (IS61WV25632Axx)

speed = 20ns for V^{d d}1.65V to 2.2V

V^{d d}2.4V to 3.6V (IS61/64WV25632Bxx)

speed = 10ns for V^{d d}2.4V to 3.6V

speed = 8ns for V^{d d}3.3V + 5%

• Packages available:

The device is packaged in the JEDEC standard 90-ball

BGA (8mm x 13mm).

–

90-ball miniBGA (8mm x 13mm)

• Industrial and Automotive Temperature Support

• Lead-free available
