5.0 OR 3.0V, 512 bit 64 x 8 SERIAL RTC and NVRAM SUPERVISOR

SUMMARY DESCRIPTION The M41ST85Y/W Serial TIMEKEEPER®/Controller SRAM is a low power 512-bit, static CMOS SRAM organized as 64 words by 8 bits. A built-in 32.768 kHz oscillator (external crystal controlled) and 8 bytes of the SRAM (see Table 2., page 14) are used for the clock/calendar function
