APExx12 Series

1.0 General Description

The APExx12 series are very low cost voice and melody synthesizer with 4-bits CPU. They have various

features including 4-bits ALU, ROM, RAM, I/O ports, timers, clock generator, voice and melody

synthesizer, and PWM (Direct drive) or D/A current outputs, 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: 16k x 10 bits

(3) 1 set of 16-bits DPR can access up to 64k x 10 bits melody data memory space, and 1 set of 18-bits

VPR can access up to 256k x 10 bits voice data memory space.
