Version: 1.0

LOW POWER SOUND CONTROLLER SERIES

1. GENERAL DESCRIPTION

The GPCL A1/B1 series, a speech/wavetable synthesizer, features

an 8-bit CMOS microprocessor, 128-byte working SRAM and

working ROM (The different body equips different ROM size.).

Other primary features include two 8-bit Timer/Counters, which

can cascade to one 16-bit timer/counter, 12 Software Selectable

I/Os and a pair of PWM output.

It is designed for wide input

voltage (1.0V ~ 1.7V; 1.3V~3.6V), and the circuit works at a stable

and programmable pumped voltage (3.3V ~ 3.9V; 3.3V ~ 4.5V).

Plus, a Clock Stop mode is built in for power savings.

The

unique power saving mode saves the RAM contents, but it freezes

the oscillator to stop executing other functions.

The maximum

CPU frequency can run up to 6MHz and the instruction cycle is

two clock cycles (min.) ~ six clock cycles (max.).
