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.
