2. General Description
The T81L0003B is 8-bit microcontroller
designed and developed with low power and high
speed CMOS technology. It contains a 8K bytes
OTP ROM, a 256 × 8 RAM, 13 I/O lines, a
watchdog timer, two 16-bit counter/timers, a
seven source, two-priority level nested interrupt
structure, a full duplex UART, and an on-chip
oscillator and clock circuits.
In addition, the T81L0003B has two selectable
modes of power reduction-idle mode and
power-down mode. The idle mode freezes the
CPU while allowing the RAM, timers, serial port,
and interrupt system to continue functioning. The
power-down mode saves the RAM contents but
freezes the oscillator, causing all other chip
functions to be inoperative.
