The AM4EE 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).
Single power supply can operate from 2.2~5.5V at 4MHz or 3.6~5.5V at 8MHz
Program ROM: 16k x 10 bits
128 x 4-bits data RAM
On-chip clock generator: Resistive Clock Drive (RM) or Crystal oscillator (HM)
4-bits I/O Port A, B , C and D
Timer: 1-set Voice Interrupt (Timer0: a 9-bits auto-reload timer/counter)
Stack: 2-level subroutine nesting
Built-in 4-level Volume Control can be programmed
Built-in 8-level DAC current output can be configured
Built-in IR Carrier Output
External Reset
HALT and Release from HALT function to reduce power consumption
Watch Dog Timer
Instruction: 1-cycle instruction except for table read and program branches which are 2-cycles
Number of instruction: 27
DAC: 1 channel voice and dual tone melody synthesizer (One 9-bits Cout or 8-bits PWM output)
