GPC10048A数据手册Generalplus中文资料规格书

描述 Description

SOUND CONTROLLER WITH 48K-BYTE ROMThe GPC10048A, a speech/wavetable synthesizer, equips an 8-bit CMOS microprocessor, and 48K-byte Working ROM, 128-byte working SRAM. Other primary features include two 8-bit Timer/Counters and can cascade to one 16-bit timer/counter, 8 Software Selectable I/Os, One 8-bit DAC and a pair of PWM output. It operates at a wide voltage range of 2.4V - 5.5V. Plus, a Clock Stop mode is built in for power savings. The unique power saving mode saves the RAM contents, but freezes the oscillator to stop executing other functions. The maximum CPU frequency can run up to 8MHz and the instruction cycle is two clock cycles (min.) ~ six clock cycles (max.). The GPC10048A loads, not only the latest technology, but also the full commitment and technical support of Generalplus.
