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.
