描述 Description

The GPLB52640A/GPLB52320A/GPLB51640A/GPLB51320A, an 8-bit CMOS microprocessor, contain 1536 bytes working RAM, 16 I/Os, interrupt/wakeup controller, two 16-bit timers, SPI interface, one 12-bit DAC, one 10-bit PWM, and automatic display controller/driver for mono/4-gray-level LCD. The GPLB52640A/ GPLB51640A contain 640K bytes ROM memory and the GPLB52320A/GPLB51320A contain 320K bytes ROM memory. The GPLB52640A/GPLB52320A contain up to 64 segments and 32 commons, forming a maximum of 2048 dots LCD resolution, and the GPLB51640A/GPLB51320A contain up to 74 segments and 22 commons, forming a maximum of 1628 dots LCD. The microprocessor can implement software for audio processing, functional control and others. For audio processing, melody and speech can be mixed into one output. The GPLB52640A/ GPLB52320A/ GPLB51640A/ GPLB51320A implement 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 and a Low Voltage Reset function to assure CPU operation properly under a low voltage condition. It also 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 communicating with other devices. Furthermore, a SLEEP (power-down) function is also built-in to extend battery life. The GPLB52640A/ GPLB52320A/ GPLB51640A/ GPLB51320A are designed with state-of-the-art technology to fulfill LCD application needs, especially for hand-held products.
