Description:The M41ST87Y/W Serial TIMEKEEPER®/Con- troller SRAM is a low power 1280-bit, static CMOS SRAM organized as 160 bytes by 8 bits. A built-in 32.768 kHz oscillator (internal crystal-controlled) and 8 bytes of the SRAM (see Table 6., page 23) are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. An additional 11 bytes of RAM provide calibration, status/control of Alarm, Watchdog, Tamper, and Square Wave functions. 8 bytes of ROM and final- ly 128 bytes of User RAM are also provided. Ad- dresses and data are transferred serially via a two line, bi-directional I2C interface. The built-in ad- dress register is incremented automatically after each WRITE or READ data byte. The M41ST87Y/ W has a built-in power sense circuit which detects power failures and automatically switches to the battery supply when a power failure occurs. The energy needed to sustain the SRAM and clock op- erations can be supplied by a small lithium button- cell supply when a power failure occurs. Functions available to the user include a non-vol- atile, time-of-day clock/calendar, Alarm interrupts, Tamper Detection, Watchdog Timer, and pro- grammable Square Wave output. Other features include a Power-On Reset as well as two addition- al debounced inputs (RSTIN1 and RSTIN2) which can also generate an output Reset (RST). The
