Products - GPL193A

General Description

GPL193A, an 8-bit CMOS microprocessor, features 704 bytes working RAM, 512K bytes of ROM, I/Os, interrupt/wakeup controller, UART for serial communication, and automatic display controller/driver for LCD.  It has one PWM driver with two audio channel outputs.  Attractive sound effects can easily be generated.   Its large ROM area can be used to store both program and audio data (speech duration is approx. 160 seconds at a 6KHz sampling rate using 4-bit ADPCM).  The built-in UART is capable of accelerating data transmission speed between two chips.  Furthermore, a SLEEP (power-down) feature is also built-in to reduce power consumption.  GPL193A is designed with state-of-the-art technology to fulfill LCD application requirements, especially for hand-held products.
