General Description

The GPL85110A, an 8-bit microprocessor, features 1M bytes Mask ROM, 1.5K bytes working RAM, 512 bytes LCD RAM, 22 I/Os, interrupt/ wakeup controller, two 16-bit timers, two SPI interfaces, a 14-bit DAC with push-pull amplifier for driving speaker directly and automatic display controller/ driver for mono LCD. The GPL85110A contains 64 segments and 32 commons, forming a maximum of 2048 dots LCD resolution. The GPL85110A operates over a wide voltage ranged from 2.3V through 5.5V. The Low Voltage Reset function assures system still functions properly when power drops below certain level. The microprocessor can implement software for audio processing, functional control and others. The GPL85110A carries a high performance SPU voice engine to achieve 8-channel voice with ADPCM/PCM data. It can produce attractive and high resolution sound easily. Plus, it features one 14-bit DAC with push-pull amplifier for driving speaker directly. Its large memory area can be used to store both program and audio data. There is a Serial Peripheral Interface (SPI) controller built-in to facilitate communicating with other devices. Furthermore, a SLEEP (power-down) function is also built-in to extend battery life. The GPL85110A is designed with state-of-the-art technology to fulfill LCD application needs, especially for hand-held products.
