1.0 General Description
The AM4EB 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) 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 2.2~5.5V at 4MHz or 3.6~5.5V at 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.
