GPC192A数据手册Generalplus中文资料规格书

描述 Description

The GPC192A is a CPU based two-channel speech/melody synthesizer which includes a CMOS 8-bit microprocessor, 192K-byte ROM for speech and melody data (speech compressed by a 4-bit ADPCM with approx. 63 sec speech duration @ 6.0KHz sampling rate) and 1K-byte working SRAM. In addition, it includes two timer/counters, 10-bit ADC, PGA, 8 x 10 FIFO, two OP Amp., 32 software programmable I/Os, and one PWM audio output. For audio processing, melody and speech can be mixed into one output. It operates over a wide voltage range of 2.4V - 5.5V. The Low Voltage Reset function automatically resets CPU whenever the working voltage drops below 2.2V. Moreover, GPC192A has a Clock Stop mode for power savings that saves the RAM contents, but freezes the oscillator. The Clock Stop mode makes all other functions inoperative. The maximum CPU clock frequency is 5.0MHz. It has an Instruction Cycle Rate of 2 clock cycles (min.) - 6 clock cycles (max.). The GPC192A includes not only the latest technology, but also the full commitment and technical support of Generalplus.
