The GPLB52320A1, an 8-bit CMOS microprocessor, features 1536 bytes working RAM, 320K bytes ROM memory, 16 I/Os, interrupt/wakeup controller, 2 sets of 16-bit timers, SPI interface, 1 set of 12-bit DAC, 1 set of 10-bit PWM, and automatic display controller/driver for mono/4-gray-level LCD. The GPLB52320A1 contains up to 64 segments and 32 commons, forming a maximum of 2048 dots LCD resolution. The microprocessor can implement software for audio processing, functional control and others. In audio processing, melody and speech can be mixed into one output. The GPLB52320A1 also carries a high performance SPU voice engine to achieve 8-channel voice with ADPCM/PCM data. It operates over a wide voltage range from 2.4V through 5.5V, plus Low Voltage Reset function to assure system will still function properly when power drops below certain level. Plus, it features one 10-bit PWM driver and one 12-bit DAC with 8 audio channels to produce attractive sound effects easily. Its large ROM area can be used to store both program and audio data. There is a Serial Peripheral Interface (SPI) controller built-in to facilitate the way to communicate with other devices. Furthermore, a SLEEP (power-down) function is also built in to preserve battery life. The GPLB52320A1 is designed with state-of-the-art technology to fulfill LCD application needs, especially for hand-held products.
