SRM2B256SLMX

55/70/10

256K-BIT STATIC RAM

Wide Temperature Range

Extremely Low Standby Current

Access Time 100ns (2.7V) 55ns (4.5V)

32,768 Words

8-Bit Asynchronous

DESCRIPTION

The SRM2B256SLMX is a low voltage operating 32,768 words

8-bit asynchronous, static, random

access memory fabricated using an advanced CMOS technology. Its very low standby power con-

sumption makes it ideal for applications requiring non-volatile storage with back-up batteries, and

–25 to 85

C operating temperature range makes it ideal for industrial use. The asynchronous and

static nature of the memory requires no external clock or refresh circuit. 3-state output ports allow easy

expansion of memory capacity. These features make the SRM2B256SLMX usable for a wide range

of applications, from microprocessor systems to terminal devices.
