TH040 Trigger Voice Combination Example
Voice File |
Description |
Voice File A |
Hello ( 1.5”) |
Voice File B |
Good Morning (3”) |
Voice File C |
John (1”) |
Voice File D |
Tom (1”) |
Voice File E |
Mary (1.5”) |
|
|
Group1 = Step1 + Step 2
Group 2 = Step3 + Step 4 + Step 5
Group 3 = Step 6 + Step 7
Group1 = Hello John
Group 2= Hello Tom Good Morning
Group 3 = Good Morning Mary
Step1 = Voice File A
Step 2 = Voice File C
Step 3 = Voice File A
Step 4 = Voice File D
Step 5 = Voice File B
Step 6 = Voice File B
Step 7 = Voice File E
Total use 3 Group , 7 Steps
Voice duration= Hello + Good Morning + John + Tom + Mary
= 1.5” + 3” + 1” + 1” + 1.5”
= 8”
Total duration = 8” ( 20”-8” = 32” space are free , can add more Voice File )

產(chǎn)品優(yōu)勢：
1,
Otp-TF040 內(nèi)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(fèi)用給您節(jié)省30%－50% .
2, 工作電壓2.4V—5.5V；輸出方式：PWM＆DAC .(應(yīng)用于5V方案時，需要加LDO降壓芯片)
3, 當(dāng)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(chǎn)品,不需光罩費(fèi),音質(zhì)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(chǎn)品，直接綁定生產(chǎn)，大大地節(jié)約生產(chǎn)時間, dip、 SOP、COB 1天交貨，裸片5-7天交貨。
