2. General Description

The T81L0010B 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, 1k bits EEPROM, 15 I/O

lines, a watchdog timer, two 16-bit counter/timers,

a seven source, two-priority level nested interrupt

structure,

oscillator and clock circuits.

In addition, the T81L0010B 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.
