www.DataSheet4U.com SRM2B256SLMX55/70/10 256K-BIT STATIC RAM q q q q Wide Temperature Range Extremely Low Standby Current Access Time 100ns (2.7V) 55ns (4.5V) 32,768 Words × 8-Bit Asynchronous s 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 consumption 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. s FEATURES Wide temperature range . . . . . . . . . . . –25 to 85°C Extended supply voltage range. . . . . . 2.7 to 5.5V Fast access time . . . . . . . . . . . . . . . . . 100ns (3V ± 10%) 55ns (5V ± 10%) Extremely low standby current . . . . . .
