产品优势：
1,
Otp-TF020 内置电阻、外围没有元器件，外围电路只需要要104电容．
整个方案的费用给您节省30%－50% .
2, 工作电压2.4V—3.6V；输出方式：PWM＆DAC .(应用于5V方案时，需要加LDO降压芯片)
3, 当今市场唯一一款8Pin的DIP,SOP封装OTP语音芯片.AT@CHIP
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.
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。
