Features Compatible with MCS-51 Embedded 8K Bytes OTP ROM Embedded 1k bits EEPROM 256 x 8-bit Internal RAM 15 Programmable I/O Lines 2 16-bit Timer/Counter & 1 16-bit Timer 2 External Interrupt Input Programmable Serial UART Interface Low Power Idle & Power-down Modes Watch-dog Timer On-chip Crystal & RC Oscillator (Selected by Bonding Option) Internal Power-on Reset and External Reset Supported 32-pin LQFP Package 3.3V Operating Voltage 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, a full duplex UART, and an on-chip 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. 3.
