描述 Description

The GPCL A1 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.).
