NY5B/九齊NYQuest產(chǎn)品線

 1. 概述

NY5BxxxB 系列產(chǎn)品為多功能單芯片CMOS語音合成4位微控制器，提供4信道的語音/Midi合成功能，語音合成方式采用先進(jìn)的高音質(zhì)ADPCM算法，最高采樣率可達(dá)CD音質(zhì)44.1kHz，且硬件有16階的音量控制。提供兩種聲音輸出方式可供選擇，一種PWM輸出和一種DAC輸出。使用RISC精簡指令集架構(gòu)，共有48條指令，除了少數(shù)指令需要2個(gè)時(shí)序，大多數(shù)指令都是1個(gè)時(shí)序即可完成，可以很方便的以程控來完成不同的應(yīng)用。利用精準(zhǔn)的+/-1%內(nèi)阻震蕩，客戶可以不需外加震蕩電阻，但是彈性的預(yù)留一個(gè)OSC腳位可以外接震蕩電阻，當(dāng)只使用內(nèi)阻震蕩時(shí)，此腳可以當(dāng)作一般I/O腳使用。提供待機(jī)模式(Halt mode)，可大幅度的節(jié)省功耗；另外還提供慢速模式(Slow mode)，可以降低功耗。

The NY5BxxxB series IC is a powerful 4-bit micro-controller based sound processor. 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 of CD quality and 16 different volume levels are supported. It is also equipped two kinds of audio outputs with fine resolution, including a current D/A converter and a PAC80FWM 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 setting internal oscillation only. Furthermore, in addition to the HALT mode (sleep mode), it also offers the SLOW mode to min
