APExx16 Series
1.0 General Description
The APExx16 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 ( APE8416 /APE10616 /APE12716 are 64k 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 19-bits
VPR can access up to 512k x 10 bits voice data memory space.
