8-bit MCU

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. By TM Technology Inc.
