Integrated Circuits Inc. API4000-6 http : // www.aplusinc.com.tw Tel : 886-2-2782-92661 API4000-6 340” VOICE OTP API4000-6 IC is a 340 seconds ( Voive sample rate is in 6 khz ) and very low cost voice synthesizer with 4-bit microprocessor. It has variousfeatures 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). Feature : ¾ Single power supply can operate from 2.4V through 4.5V. ¾ Voice length : 340 seconds ( Voive sample rate is in 6 khz ) . ¾ Internal Program ROM: 4K x 10-bit. ¾ Data Registers:
- 96 x 4-bit data RAM (00-1Fh plus 40h-7Fh)
- Unbanked special function regi sters (SFR) range: 20h-3Fh ¾ 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) ¾ On-chip clock generator: Resistive Clock Drive(RM) ¾ Timer: 1
- Timer0: a 9-bit auto-reload timer/counter. ¾ Stack: 2-level subroutine nesting. ¾ HALT and Release from HALT function to reduce power consumption. ¾ Watch Dog Timer (WDT). ¾ Voice format : Linear Scale 5 bit output . ¾ Voice Sample Rate Range :4K - 22KHz . ¾ Tg mode :Level / Edge ,Hold / Unhold , Retrigger / Ir- Retrigger .
