产品资讯 - GPLB62P100UA1 (OTP)*

General Description

The GPLB62P100UA1, an 8-bit microprocessor for handheld LCD product, features 2M bytes OTP ROM, 2560 bytes working RAM,1536 bytes LCD RAM, 22 I/Os, two 16-bit timers, two SPI interfaces, and automatic display controller/ driver for mono/ 4-gray-level LCD. In graphic features, GPLB62P100UA1 contains up to 74 segments and 32 commons, forming a maximum of 2,368 dots LCD resolution. Besides the built-in driver function, the common/segment could be extended with external drivers such as GPLD2080A and GPLD2120A. A LCD sprite function is included in GPLB62P100UA1; it is capable of operating over a wide voltage range from 2.3V through 5.5V, and Low Voltage Reset function to keep system operating properly when power drops below certain level. The GPLB62P100UA1 carries a high performance SPU voice engine to achieve 8-channel ADPCM/PCM high quality voice. Plus, it features one 14-bit DAC with push-pull amplifier to drive 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 super high speed with reliability as well. 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.
