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).
