          l 2K*14 bits mask ROM.

          l 80*8 bits SRAM.

          l I/O pins: P1.0~P1.4, P2.0~P2.7. P1.4, P2.6, P2.7 can be used as OSCI, BZ, BZB by mask option.

          l 4 level stacks for subroutine nesting.

          l Clock Sources

－ 32768Hz crystal oscillator with external crystal.

－ RC oscillator with external resistor.

          l Oscillator mode

－ 32768Hz crystal oscillator and RC oscillator are both available. - 32768Hz crystal oscillator work only. - 32768Hz crystal oscillator and RC oscillator work together. － RC oscillator is available only.

          l When 32768Hz crystal oscillator and RC oscillator work together, MCU supports five work modes to reduce the current consumer.

－ Normal: MCU, 32768Hz clock and RC oscillator turn on.

－ Slow: MCU and 32768Hz clock turn on, RC oscillator turn off.

－ Sleep: MCU and 32768Hz clock turn off, RC oscillator turn off.

－ Idle: MCU turn off, 32768Hz clock turn on, RC oscillator turn off.

          l When RC oscillator is available only, MCU supports three work modes to reduce the current consumer.

－ Normal: MCU and RC oscillator turn on.

－ Idle: MCU turn off, RC oscillator turn on.

－ Sleep: MCU and RC oscillator turn off.

          l When 32768Hz crystal oscillator work only, MCU supports three work modes to reduce the current consumer.

－ Slow: MCU and 32768Hz crystal oscillator turn on.

－ Idle: MCU turn off, 32768Hz crystal oscillator turn on.

－ Sleep: MCU and 32768Hz crystal oscillator turn off.

          l Interrupt sources:

－ 1 software interrupt (by excuting ‗INT‘ instruction)

－ 3 hardware interrupt sources :RTC overflow interrupt, TCC overflow interrupt, 1 external interrupt (P2.0/INT).

          l Built-in programmable sound generator (PJTMS).

          l Built-in power on reset (POR).

          l Oscillator Start-up Timer (OST).

          l CMOS technology for low power consumption.

LCD Module Features

          l LCD operation current:

－ Stand by current:<4uA

          l 57(3*19) dots (1/2 bias, 1/3 duty).

－ Typical operation voltage of LCD panel:

－ Typical operation voltage of LCD panel: 3V

          l 76(4*19) dots (1/3 bias, 1/4 duty).

－ Typical operation voltage of LCD panel: 4.5V
