產品優(yōu)勢：
1,
Otp-TF020 內置電阻、外圍沒有元器件，外圍電路只需要要104電容．
整個方案的費用給您節(jié)省30%－50% .
2, 工作電壓2.4V—3.6V；輸出方式：PWM＆DAC .(應用于5V方案時，需要加LDO降壓芯片)
3, 當今市場唯一一款8Pin的DIP,SOP封裝OTP語音芯片.AT@CHIP
4, 唯一一款可以燒錄裸片出貨的OTP語音芯片產品,不需光罩費,音質和單價市場最優(yōu).
出貨形式：
dip、 SOP、COB（可為積壓盒專用）、裸片（已燒錄好）。 其中裸片一塊Wafer可以同時燒錄4款不同的產品，直接綁定生產，大大地節(jié)約生產時間, dip、 SOP、COB 1天交貨，裸片5-7天交貨。
