NY5P/九齐NYQuest产品线

 1. 概述

NY5P系列产品为多功能单芯片CMOS语音合成4位微控制器，是九齐科技为了支持NY5A, NY5B, NY5C 系列MaskROM 产品所专门开发的崁入式EPROM架构的OTP IC (One Time Programmable)。提供4信道的语音/Midi合成功能，语音合成方式采用先进的高音质ADPCM算法，最高采样率可达CD音质44.1kHz，且硬件有16阶的音量控制。提供两种声音输出方式可供选择，一种PWM输出和一种DAC输出。使用RISC精简指令集架构，共有48条指令，除了少数指令需要2个时序，大多数指令都是1个时序即可完成，可以很方便的以程控来完成不同的应用。利用精准的+/-1%内阻震荡，客户可以不需外加震荡电阻，但是弹性的预留一个OSC脚位可以外接震荡电阻，当只使用内阻震荡时，此脚可以当作一般I/O脚使用。提供待机模式(Halt mode)，可大幅度的节省功耗；另外还提供慢速模式(Slow mode)，可以降低功耗。

The NY5P series IC is a powerful 4-bit micro-controller based sound processor. They are embedded EPROM architecture, and the OTP (One Time Programmable) ICs that are designed to support NY5A, NY5B and NY5C MaskROM products. There are 4 channels that are configured as speech or midi, and all of them can be auto-played back simultaneously. By using the high fidelity ADPCM speech synthesis algorithm, it can produce outstanding quality voices. Wide range sampling rate up to 44.1kHz and different volume level arAC80Fe supported. It is also equipped two kinds of audio outputs with fine resolution, including a current D/A converter and a PWM direct-drive. The RISC MCU architecture is very easy to program and control, various applications can be easily implemented. There are 48 instructions, and most of them are executed in single cycle. Through +/-1% accurate internal oscillation, external Rosc is mostly unnecessary. Also an OSC pad is reserved for external oscillation, and this pad can be optioned as normal I/O when set
