DESCRIPTION q Low Supply Voltage q Wide Temperature Range q Low Supply Current q Access Time 70ns (2.7V) q 131,072 Words×8-Bit Asynchronous The SRM20V100LLMX 7 is an 131,072 words×8-bit asynchronous, static, random access memory on a monolithic CMOS chip. Its very low standby power requirement 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 portable equipment. The asynchronous and static nature of the memory requires no external clock or refreshing circuit. Both the input and output ports are TTL patible and 3-state output allows easy expansion of memory capacity. s FEATURES q Wide temperature range - 25 to 85°C q Fast Access time SRM20V100LLMX7 70ns (Max.) q Low supply current standby: 0.6µA (Typ.): LL Version 0.3µA (Typ.): SL Version operation: 8m A/1MHz (Typ.) q pletely static No clock required q Supply voltage 2.7V to 3.6V q TTL patible inputs and outputs q 3-state output with wired-OR capability q Non-volatile storage with back-up batteries SOP6-32pin (plastic) q Package SRM20V100LLMX7 SRM20V100LLTX7 TSOP ( I )-32pin (plastic) SRM20V100LLRX7 TSOP ( I )-32pin-R1 (plastic) SRM20V100LLKX7 Slim-TSOP ( I )-32pin (plastic) SRM20V100LLYX7 Slim-TSOP ( I )-32pin-R1 (plastic) s PIN CONFIGURATION (SOP6) N.C.
