ASM3112C/4112C – VERY LOW-COST VOICE SYNTHESIZER WITH 4-BIT MICROPROCESSOR
1.0 General Description The ASM3112C/4112C is very low cost voice synthesizer with 4-bit microprocessor. It has various features including 4-bit ALU, ROM, RAM, I/O ports, timers, clock generator, watchdog timer(WDT), voice synthesizer, etc. It consists of 22 instructions in the device. With CMOS technology and halt function can minimize power dissipation. Its architecture is similar to RISC, with two stages of instruction pipeline. It allows all instructions to be executed in a single cycle, except for program branches and data table read instructions (which need two instruction cycles). 1.1 Feature Single power supply can operate from 2.4V through 5.
