OTPG系列20秒语音芯片资料:

    AC9020-OTPG系列是深圳市环芯半导体有限公司2009年推出的新产品,在复位和内部供电方面有了更大的改善,同时推出新的烧录工具和编程软件,解决了AC8020原来仅支持3V供电的情况,5V供电时在VDD外加一个电阻的情况下,提供稳定性能的语音输出.同时在功能方面有了更大的改进.

    AC9020 20秒新的OTPG语音芯片系列,是一颗支持PWM和DAC输出的20秒的OTP语音芯片,音质效果好，共有4个I/O口,其中2个Input,2个简单I/O,简单I/O只能触发单段语音或用于马达和闪灯，外围仅需一颗104电容，产品方案成本极低.

产品优势：

1, Otp-AC9020 内置电阻、外围没有元器件，外围电路只需要要104电容．AT@CHIP

　　整个方案的费用给您节省30%－50% .

2, 工作电压默认为2.4V—3.6V,使用4.5V供电时在VDD上连一个8欧电阻即可,纽扣电池供电时只需连个4欧电阻；输出方式：PWM＆DAC .

3, 有8Pin, DIP8和SOP8,裸片封装可以选择.

4, 唯一一款可以烧录裸片出货的OTP语音芯片产品,不需光罩费,音质和单价市场最优.

5, 喇叭是8欧0.5W的,支持8欧阻值功率范围 : 0.25W-1W的喇叭. 半 环 导 芯 体

6, 声音DAC输出时,在DAC Pin和VSS之间的电阻为470欧.

出货形式：

dip、 SOP、COB（可为积压盒专用）、裸片（已烧录好）。 其中裸片一块Wafer可以同时烧录4款不同的产品，直接绑定生产，大大地节约生产时间, dip、 SOP、COB 1天交货，裸片5-7天交货。
