8-bit MCUThe 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. By TM Technology Inc.
