General Description

The GPL83110UA, an 8-bit microprocessor for LCD handheld products developed by Generalplus, features 1M bytes Mask ROM, 1.5K bytes working RAM, 512 bytes LCD RAM, 22 I/Os, two 16-bit timers, two SPI interfaces, a 14-bit DAC with push-pull amplifier for driving speaker directly, automatic display controller/ driver for mono LCD. In display features, it contains up to 48 segments and 32 commons, forming a maximum of 1536 dots LCD resolution. The GPL83110UA is designed to operate over a wide voltage, ranging from 2.3V through 5.5V. In addition, Low Voltage Reset function assures system keep operating properly when power drops below certain level. The GPL83110UA is incorporated a high performance SPU engine to implement 8-channel ADPCM/PCM high quality voice. Moreover, it has one 14-bit DAC with push-pull amplifier for driving speaker directly. Its large memory area allows user to store both program and audio data in one place. The USB device function assures data transmitted in an ultra-high speed and reliability. A Serial Peripheral Interface (SPI) controller is also built in GPL83110UA to facilitate communication between devices. For more information about GPL83110UA’s feature list, please refer to the following section.
