T81L0006A/B
8-bit A/D Type MCU
3. General Description
The T81L0006A/B is 8-bit microcontroller designed and
developed with low power and high speed CMOS
technology. It contains a 8K bytes OTP ROM, a 128 × 8
RAM, an 8-channels 8-bit A/D converter, 15/19 I/O lines, a
watchdog timer, two 16-bit counter/timers, a seven source,
two-priority level nested interrupt structure, two channel
pulsed-width modulator (PWM), a full duplex UART, and
an on-chip oscillator and clock circuits.
In addition, the T81L0006A/B 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.
