Description of this Cheapest Voice OTP IC Chip
 
WTN5 series products are multi-functional single-chip CMOS speech synthesis 4-bit controller. The existing WTN5055, WTN5025 and WTN5085 voice chips (voice length is 55s, 25s and 85s, respectively). WTN5055 and WTN5085 have been put into the market, and will soon be launched WTN5025 and WTN5085. Audio sampling rate up to 44.1 kHz, 16-level volume control, two audio output modes, PWM output and DAC output. Accurate +/-1% internal oscillation, no need for external oscillation, with ultra-low power standby. 
 
Parameters of this Cheapest Voice OTP IC Chip
 
1、Working voltage: 2.2V~5.5V.
2、In standby mode, quiescent current less than 1uA.

Advantage of this Cheapest Voice OTP IC Chip
 
Notice:
1.The supply voltage, control mode and output mode have been set when writing program, can not be changed. When customizing chip, tell salesmen about the application requirements.
2.When using serial control mode, can load 254 pieces of voice at most. If using volume control command EO~EFH, will reduce 16 pieces of voice.
 
The setting of chip voltage determines the opening and closing of the internal LDO. Pay attention to chip voltage setting which must be matched with power supply voltage and circuit wiring. Otherwise it will cause chip damage or inoperation.
Supply voltage is as below:
