General Description

The GPL10B1 is a CMOS 8-bit single chip micro-controller which contains LCD drivers, ROM, SRAM, I/O, timer/counter and tone output for directly driving buzzer on a single chip. The GPL10B1 is designed to drive LCD directly and performs efficient controller function as well as arithmetic function. With the on chip crystal oscillator, the real time clock is easily realized. For power saving, a software controllable standby switch is also built-in. The GPL10B1 is widely used in electronic products requiring very low power consumption, for example, multi-function watch, calendar, calculator, and thermometer or LCD game with audio output.


  • Built-in 8-bit CPU
  • Operating voltage: 2.0V to 5.5V
  • Max. CPU clock: 2.0MHz @ 2.0V
  • ROM capacity: 7K x 8 bits
  • RAM capacity: 96 x 8 bits
  • Direct Driver for LCD: 4 Commons X 32 Segments (1/2, 1/3 bias, 1/2, 1/3, 1/4 duty)
  • Input Port: Six input pins with key wakeup function with fourdifferent configurations (mask option)
  • I/O Port: Four special purpose I/O for implement thermometer
  • Timer/Counter: one 12-bit timer/counter
  • Six Interrupt sources:
    • External Interrupt
    • Timer Interrupt
    • 2KHz Interrupt
    • LCD Service Interrupt (in LCD share mode)
    • 128Hz Interrupt
    • 2Hz Interrupt
  • Dual Clock System: One built-in RC oscillatorthat select internal or external resistor (mask option) for CPU. The other built-in crystaloscillator or RC oscillator (mask option) for LCD scanning.
  • Tone Output: Tone output for directly driving buzzer
  • System Reset: External Reset, Watch Dog Reset and Low Voltage Reset (2.0V) are built-in
  • Low Operating Current: Typical current < 8μA @ 3.0V for timepiece products
