They have various features including 4-bits ALU, ROM, RAM, I/O ports, timers, clock generator, voice and melody synthesizer, and PWM (Direct drive) output, etc. The audio synthesizer contains one voice-channel and two melody-channels. Furthermore, they consist of 27 instructions in these devices. With CMOS technology and halt function can minimize power dissipation. Their architectures are similar to RISC, with two stages of instruction pipeline. They allow all instructions to be executed in a single cycle, except for program branches and data table read instructions (which need two instruction cycles). 2.0 Features (1) Single power supply can operate from 2.4V to 5.5V at 4MHz or 8MHz. (2) Program ROM: 8k x 10 bits (3) 1 set of 15-bits DPR can access up to 32k x 10 bits melody data memory space, and 1 set of 15-bits VPR can access up to 32k x 10 bits voice data memory space.
