General Description

The GPL81408A, an 8-bit CMOS single chip microprocessor, contains RAM, ROM, I/Os, interrupt/wakeup controller, timer, 8-bit PWM audio output and automatic display controller/ driver for LCD.  With a dual channel PWM driver, attractive sound effects can be generated easily.  Furthermore, a software controllable standby mode is also implemented for power saving.


Features

  • Built-in 8-bit CPU
    • 160 bytes SRAM
    • 64K bytes ROM
    • CPU clock: 2.0MHz @ 2.0V – 5.5V
    • Programmable CPU clock frequency, 1/2, 1/4, 1/8, 1/16, 1/32 or 1/64 of Internal R-oscillator’s clock frequency is available.
    • Provides 7 interrupt sources
  • Built-in 8-bit 1-channel PWM outputs
  • Built-in 32.768KHz Crystal / R-oscillator
    • Crystal or R-oscillator (mask option)
    • Crystal oscillator switches from strong to Weak mode automatically
    • Internal time base generator
  • Built-in System R-oscillator
    • No resistor is needed
  • One 16-bit timer/counters
  • Low Voltage Reset
    • Provides 1.9V low voltage reset function
  • Low power consumption
    • Operating current: 500uA/1.0MHz @ 3.0V
    • Very low standby current : ISTBY < 1.0µA @ 3.0V
