AM4EC series rev 1.6 2004/7/1 1 1.0 general description the AM4EC 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, t hey consist of 27 instructions in these devices. with cmos technology and halt function can minimize po wer 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: 16k x 10 bits (3) 1 set of 16-bits dpr can access up to 64k x 10 bi ts melody data memory space, and 1 set of 18-bits vpr can access up to 256k x 10 bits voice data memory space. product voice duration (sec) voice pointer (vpr) rom size (10-bit) AM4EC005x 5 14-bits 16k AM4EC010x 10 15-bits 32k AM4EC015x 15 16-bits 48k AM4EC020x 20 16-bits 64k AM4EC031x 31 17-bits 96k AM4EC041x 41 17-bits 128k AM4EC052x 52 18-bits 160k AM4EC063x 63 18-bits 192k (4) data registers: a). 128 x 4-bits data ram (00-7fh) (4ec005x/4ec010x are 96 x 4-bits data ram 00-5fh) b). unbanked special function registers (sfr) range: 00h-2fh (5) i/o ports: a). pra: 4-bits i/o port a (10h) can be programm ed to input/output individually.

(9) built-in 4-level volume control can be programmed. (10) built-in 8-level dac current output can be configured. (mask option) (11) built-in ir carrier output: port b[1] can be co nfigured as ir pin by 38k / 56khz. (mask option)
