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.
