OTP Voice Chip
OTP (One Time Programmable) voice chip means one-time programmable voice chip, Widely used in electronic locks, home appliances, and various application scenarios that require convenient sound prompt.
WTN6 Series OTP Voice IC
The WTN6 series is a multifunctional, low-power, high-performance CMOS voice chip. Currently, there are four types of chips available: WTN6020, WTN6040, WTN6080, and WTN6170 (with voice lengths of 20 seconds, 40 seconds, 80 seconds, and 170 seconds respectively). These chips have already been launched in the market. The audio sampling rate can currently reach up to 32 kHz, with 16-level volume control and two audio output methods: PWM output and DAC output. It features precise internal oscillation of +/-1%, eliminating the need for external oscillation, and boasts ultra-low power consumption in standby mode.

Chip Selection
We offer various models of OTP voice chips for your selection, meeting your diverse application needs. Clicking on the image will provide detailed information.
- With voice lengths of 20 seconds
- With voice lengths of 40 seconds
- With voice lengths of 80 seconds
- With voice lengths of 170 seconds
Functional overview
- (1) Operating voltage: 2.4V to 5.2V;
- (2) In standby mode, static current is less than 5 microamperes (the DATA/CLK signal lines can remain at a stable level for about 2 seconds after voice playback completes before entering sleep mode);
- (3) Accurate internal oscillation of +/-1%, with low-voltage reset (LVR=2.0V);
- (4) 12-bit PWM pure audio output, capable of directly driving an 8Ω/0.5W speaker and buzzer, DAC audio output, external amplifier can be connected;
- (5) Serial control mode available: pulse counting, button, one-wire serial port, two-wire serial port (up to 224 segments of voice can be loaded, detailed explanation follows);
- (6) Supports BUSY status output.
OTP Voice Chips
OTP refers to a one-time programmable voice chip, which can only burn and write voice once. It is suitable for applications where there is no need to modify the voice and the voice length is short. Its characteristics are single-chip solution and low price.
WTN6 Series
- The factory settings for the program and voice cannot be changed later.
- We can provide bare boards for testing, or test boards equipped with MCU, buttons, and amplifiers.
Application Range
Due to its sound being customizable only once, the price is relatively low, making it suitable for applications in mid-to-low-end toys, electronic keyboards, electric vehicles, small household appliances, medical devices, and other products.

Frequently Asked Questions
Cannot re burn voice, WTN6 chip belongs to OTP class chip and only supports burning voice once.
The WTN6 series requires us to be informed of any business modifications.
Waytronic’s DACs are all simulated through software. The hardware of the WTN6 series with DAC refers to the built-in filtering circuit in the chip, which can be easily added to the fifth pin with a 102 capacitor to achieve a DAC like output.
When the PWM direct push horn outputs, the peak current is around 300mA, and during sleep, it is within 5uA.
WTN6 series or WT588F series single byte, usually 223 segments; The theoretical maximum support for WT588F double byte is 56799 segments, but the more segments there are, the lower the space utilization may be because addressing becomes very large.
OTP (One Time Programmable) refers to a one-time programmable voice chip that can only burn and write voice once. It is suitable for applications where there is no need to modify the voice and the voice length is short. The playback length can be divided into 10 seconds, 20 seconds, 40 seconds, 80 seconds, and 170 seconds.
The characteristics of OTP voice chip are single-chip solution, low price, suitable for small and medium-sized batch production, and even small quantity production can be timely delivered. Mainly used in mid to low end toys, electronic keyboards, electric vehicles and other products.
Contact Waytronic’s online customer service or send us an email with the subject line explaining what product to use and a brief description of functional requirements. Waytronic’s professional engineers will send you the best selection suggestions.
If it is a PWM direct output circuit, confirm that the source audio itself has no noise, and check whether there is power interference or signals from other high-frequency components; If it is a DAC plus amplifier output current, mainly check the ripple of the power supply.
The sleep power consumption of the voice chip is below 5uA, and no sleep command is required. In the idle state of the chip, after the communication pin level stabilizes for 1 second, the chip automatically enters sleep mode.
