OTP Voice Chip
OTP (One Time Programable) refers to a one-time programmable voice chip. The voice can only be programmed once. It is suitable for applications where the voice does not need to be modified and the voice length is short. The playback length can be divided into 10 seconds and 21 seconds. , 42 seconds, 85 seconds, 170 seconds, 340 seconds. The OTP voice chip is characterized by a single-chip solution, low price, and is suitable for small and medium-sized batch production. Even for small-volume production, goods can be obtained in time. Mainly used in low-end toys, electronic keyboards, electric vehicles and other products.

Overview
OTP voice chip stands for one-time-programmable voice chip, which is an ideal and mature solution playing back changeless recordings.
This chip is ideal for use in telephones, games, intelligent transport equipment like car parks and toll stations, home security alarms, children’s audiobooks, appliances and more. It is an OTP voice chip with a voice length of about 40 seconds (4KHz sampling rate). It can store 224 voice files, and it comes with an internal integrated clock oscillator. In addition, it has 10 different types of button triggers, and it has a stabilization time for the trigger. Also, the OTC voice chip can load an estimated 63 voice addresses and supports audio file playback with various sampling rates.
Product Details
- Working voltage: 2.0V~5.5V;
- In standby mode, the quiescent current is less than 5uA (after the voice playback is completed, the DATA/CLK signal line can sleep at a stable level for about 2 seconds);
- Accurate +/-1% internal oscillation, with low voltage reset (LVR=1.8V);
- 12-bit PWM pure audio output, can directly drive 8Ω/0.5W speakers and buzzer, DAC audio output, can be connected to an external power amplifier;
- With serial port control mode: count pulse, button, (up to 224 segments of voice can be loaded, consult a technical consultant for more details);
- Support BUSY status output (standard program BUSY pin is high level by default, and low level during voice playback. Can be customized (need to clarify with technical consultant).In addition, in serial port
- control mode, only when the voice chip receives the correct voice address timing sequence BUSY pin will have a level change );
