Description
The APEXX-LIP is a low-cost voice and melody synthesizer IC chip that comes with a 4-bit CPU. It is equipped with various features, including 4-bit ALU, ROM, RAM, I/O ports, timers, clock generator, and PWM output. The audio synthesizer contains one voice channel and two melody channels and consists of 27 instructions in the device. This model with CMOS technology and a halt function can minimize power dissipation. Its architecture is similar to RISC with two stages of instruction pipeline. All instructions can be executed in a single cycle except for program branches and data table read instructions, which need two instruction cycles.
Specifications and Features
- Single power supply can operate from 2.4V to 5.5V at 4MHz or 8MHz
- Program ROM: 8k x 10 bits
- 1 set of 15-bits DPR can access up to 32k x 10 bits melody data memory space, and 1 set of 15-bits VPR can access up to 32k x 10 bits voice data memory space.
- Data Registers:
- 96 x 4-bits data RAM (00-5Fh)
- Unbanked special function registers (SFR) range: 00h-2Fh
- I/O Ports:
- PRA: 4-bits I/O Port A (10h) can be programmed to input/output individually. (Register control)

- Watch Dog Timer (WDT)
- Instruction: 1-cycle instruction except for table read and program branches which are 2-cycles
- Number of instructions: 27
- DAC: 1 channel voice and dual-tone melody synthesizer (One 8-bits PWM output)
Application Scenarios
The APEXX-LIP IC chip is ideal for various voice and melody synthesizing applications. It is commonly used in low-cost devices that require voice or sound feedback, such as educational toys, musical instruments, and mobile phones.
