5.0 or 3.0V, 512 bit 64 x 8 SERIAL RTC with SUPERVISORY FUNCTIONS

SUMMARY DESCRIPTION The M41ST84Y/W Serial supervisory TIMEKEEPER® 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 9, page 16) are used for the clock/calendar function an

3.0/3.3V I2C Serial RTC with Supervisory Functions

Description The M41ST84W serial real-time clock is built in a low power CMOS SRAM process. It has a 64-byte memory space with 44 bytes of NVRAM and 20 memory-mapped RTC registers (see Table 3 on page 18). The RTC registers are configured in binary coded decimal (BCD) format. A built-in, low powe
