4 1. General Description The AM4EA_OTP series are very low cost voice and melody synthesizer with 4-bit CPU. They have various features including 4-bit ALU, EPROM, RAM, 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. Features (1) Single power supply can operate from 2.2~5.5V at 4MHz or 3.6~5.5V at 8MHz. (2) Program ROM: AM4EA015A /AM4EA031A is 16k x 10 bits; AM4EA084A/AM4EA170A is 64k x 10 bits. (3) 1 set of 16-bit DPR can access up to 64k x 10 bits melody data memory space, and 1 set of 18-bit VPR can access up to 256k x 10 bits voice data memory space. And 1 set of 19bit VPR can access up to 512 x10 bit voice data memory space.
