2.0 Features
1.0 General Description
(1) Single power supply can operate from 2.4V to 5.5V at 4MHz or 8MHz.
(2) Program ROM: 16k x 10 bits ( APE8416 /APE10616 /APE12716 are 64k x 10 bits )
(3) 1 set of 16-bits DPR can access up to 64k x 10 bits melody data memory space, and 1 set of 19-bits
(4) Data Registers:
(5) I/O Ports:
The APExx16 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).
(6) On-chip clock generator: Resistive Clock Drive (RM) or Crystal oscillator (HM)
(7) Timer: 1-set Voice Interrupt (Timer0: a 9-bits auto-reload timer/counter).
(8) Stack: 2-level subroutine nesting.
(9) Built-in 4 Level Volume Control can be programmed.
VPR can access up to 512k x 10 bits voice data memory space.
a). 128 x 4-bits data RAM (00-7Fh)
b). Unbanked special function registers (SFR) range: 00h-2Fh
a). PRA: 4-bits I/O Port A (10h) can be programmed to input/output individually. (Register control)
b). PRB: 4-bits I/O Port B (13h) can be configured to input/output individually. (Mask option)
c). PRC: 4-bits I/O Port C (14h) can be programmed to input/output individually. (Register control)
d). PRD: 4-bits I/O Port D (15h) can be programmed to input/output individually. (Register control)
