FEATURES

DESCRIPTION

The ISSI IS61/64LV51216 is a high-speed, 8M-bit static

RAMorganizedas525,288wordsby16bits.Itisfabricated

using ISSI's high-performance CMOS technology. This

highly reliable process coupled with innovative circuit de-

sign techniques, yields high-performance and low power

consumption devices.

• High-speed access time:

— 8, 10, and 12 ns

• CMOS low power operation

• Low stand-by power:

— Less than 5 mA (typ.) CMOS stand-by

• TTL compatible interface levels

• Single 3.3V power supply

When CE is HIGH (deselected), the device assumes a

standby mode at which the power dissipation can be

reduced down with CMOS input levels.

• Fully static operation: no clock or refresh

required

Easy memory 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. A data byte allows Upper Byte (UB) and Lower

Byte (LB) access.

• Three state outputs

• Data control for upper and lower bytes

• Industrial and Automotive temperatures available

• Lead-free available

The IS61/64LV51216 is packaged in the JEDEC standard

44-pin TSOP Type II and 48-pin Mini BGA (9mm x 11mm).
