| Description | 3.3V TIMEKEEPER CONTROLLER |
|
|
The M48T212A is a self-contained device that includes 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. A built-in 32.768 kHz oscillator (external crystal controlled) is used for the clock/calendar function. Access to all TIMEKEEPER functions and the external RAM is the same as...
