NY4 Series
 
Description

By using the high fidelity ADPCM speech synthesis algorithm and a built-in noise filter, NY4 can produce outstanding quality voices. Wide range sampling rate up to 44.1kHz is supported. The RISC MCU architecture is very easy to program and control, various applications can be easily implemented. There are 44 instructions, and most of them are executed in single cycle. Furthermore, a HALT mode (sleep mode) is designed to minimize power dissipation. Through +/-1% accurate internal oscillation, external Rosc is unnecessary.
