NY4B/九齊NYQuest產(chǎn)品線

 NY4B系列產(chǎn)品為單芯片CMOS語音合成4位微控制器，提供一信道的語音輸出，有一組高音質(zhì)的PWM來直推喇叭。語音合成方式采用高音質(zhì)ADPCM算法，最高采樣率可達(dá)CD音質(zhì)44.1kHz，且內(nèi)建一個噪聲濾波線路可降低背景噪音。使用RISC精簡指令集架構(gòu)，共有44條指令，除了少數(shù)指令需要2個時序，大多數(shù)指令都是1個時序即可完成，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，可以不需外加震蕩電阻。提供待機(jī)模式(Halt mode)，可大幅度的節(jié)省功耗。

The NY4B series IC is a powerful 4-bit micro-controller based sound processor. There is only 1-channel speech with high quality direct-drive PWM output. By using the high fidelity ADPCM speech synthesis algorithm and a built-in noise filter, it can produce outstanding quality voices. Wide range sampling rate up to 44.1kHz is supported. TAC80Fhe 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. Through +/-1% accurate internal oscillation, external Rosc is unnecessary. Furthermore, a HALT mode (sleep mode) is designed to minimize power dissipation.
