VERY LOW-COST VOICE SYNTHESIZER WITH 4-BIT MICROPROCESSOR
1.0 General Description
The
ASM3112C
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 5V
Internal Program ROM: 4K x 10-bit
1 sets of 17-bit DPR can access up to 96K x 10 bits data memory space
Data Registers:
96 x 4-bit data RAM (00-1Fh plus 40h-7Fh)
Unbanked special function registers (SFR) range: 20h-3Fh
I/O Ports:
PRA: 4-bit I/O Port A (2Bh)
PRB: 4-bit Output Port B (2Dh)
PRC: 4-bit Input Port C (2Fh)
On-chip clock generator:
Resistive Clock Drive
(
RM)
Timer: 1
Timer0: a 9-bit auto-reload timer/counter
Stack: 2-level subroutine nesting
HALT and Release from HALT function to reduce power consumption
Watch Dog Timer (
WDT
)
Instruction: 1-cycle instruction except for table read and program branches which are 2-cycles
Number of instruction: 22
The Voice function can be implemented by microprocessor instruction
One 8-bit COUT output for A
