AC9020-OTPG20秒 OTP語(yǔ)音芯片 產(chǎn)品原理接線資料
OTPG系列20秒語(yǔ)音芯片資料:
AC9020-OTPG系列是深圳市環(huán)芯半導(dǎo)體有限公司2009年推出的新產(chǎn)品,在復(fù)位和內(nèi)部供電方面有了更大的改善,同時(shí)推出新的燒錄工具和編程軟件,解決了AC8020原來(lái)僅支持3V供電的情況,5V供電時(shí)在VDD外加一個(gè)電阻的情況下,提供穩(wěn)定性能的語(yǔ)音輸出.同時(shí)在功能方面有了更大的改進(jìn).
AC9020 20秒新的OTPG語(yǔ)音芯片系列,是一顆支持PWM和DAC輸出的20秒的OTP語(yǔ)音芯片,音質(zhì)效果好，共有4個(gè)I/O口,其中2個(gè)Input,2個(gè)簡(jiǎn)單I/O,簡(jiǎn)單I/O只能觸發(fā)單段語(yǔ)音或用于馬達(dá)和閃燈，外圍僅需一顆104電容，產(chǎn)品方案成本極低.

產(chǎn)品優(yōu)勢(shì)：
1,
Otp-AC9020 內(nèi)置電阻、外圍沒(méi)有元器件，外圍電路只需要要104電容．AT@CHIP
整個(gè)方案的費(fèi)用給您節(jié)省30%－50% .
2, 工作電壓默認(rèn)為2.4V—3.6V,使用4.5V供電時(shí)在VDD上連一個(gè)8歐電阻即可,紐扣電池供電時(shí)只需連個(gè)4歐電阻；輸出方式：PWM＆DAC .
3, 有8Pin, DIP8和SOP8,裸片封裝可以選擇.
4, 唯一一款可以燒錄裸片出貨的OTP語(yǔ)音芯片產(chǎn)品,不需光罩費(fèi),音質(zhì)和單價(jià)市場(chǎng)最優(yōu).
5, 喇叭是8歐0.5W的,支持8歐阻值功率范圍 : 0.25W-1W的喇叭. 半 環(huán) 導(dǎo) 芯 體
6, 聲音DAC輸出時(shí),在DAC Pin和VSS之間的電阻為470歐.
出貨形式：
dip、 SOP、COB（可為積壓盒專(zhuān)用）、裸片（已燒錄好）。 其中裸片一塊Wafer可以同時(shí)燒錄4款不同的產(chǎn)品，直接綁定生產(chǎn)，大大地節(jié)約生產(chǎn)時(shí)間, dip、 SOP、COB 1天交貨，裸片5-7天交貨。
