描述 Description

32KB SOUND CONTROLLER (OTP)The GPC11033D, a speech/wavetable synthesizer, equips an 8-bit CMOS microprocessor, and 32K-byte OTP EPROM, 128-byte working SRAM. Other primary features include two 8-bit Timer/Counters and can cascade to one 16-bit timer/counter, 16 Software Selectable I/Os, One 8-bit DAC and a pair of PWM output. The PWM output volume has been improved to be similar to GPC10024D's level which is louder than GPC11024A and GPC11032A. Port IOD[3:0] provide large current direct driving for LED which can save maximum 4 transistors. (Same as GPC10024D but GPC11024A and GPC11032A didn't provide this) 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 GPC11033D loads, not only the latest technology, but also the full commitment and technical support of Generalplus.
