Description

The M48T212Y/V are self-contained devices that include a real time clock (RTC), programmable alarms, a watchdog timer, and two external chip enable outputs which provide control of up to four (two in parallel) external low-power static RAMs.

Access to all TIMEKEEPER®functions and the external RAM is the same as conventional bytewide SRAM. The 16 TIMEKEEPER Registers offer Century, Year, Month, Date, Day, Hour, Minute, Second, Calibration, Alarm, Watchdog, and Flags. Externally attached static RAMs are controlled by the M48T212Y/V via the E1CON and E2CON signals (see Table 4).

The 44 pin 330mil SOIC of M48T212Y/V provides sockets with gold plated contacts at both ends for direct connection to a separate SNAPHAT housing containing the battery and crystal. The unique design allows the SNAPHAT battery package to be mounted on top of the SOIC package after the completion of the surface mount process.
