Flash Voice Chips
Tips
The rewritable Flash voice chip is a voice processing chip that adopts a Flash storage architecture. Compared with the traditional OTP voice chip, it has advantages such as being repeatedly programmable and flexible for updates. Allow users to update the voice content independently through the supporting tools, eliminating the risk of scrapping OTP voice chips due to program errors.If you need to select voice chips and learn more information, please be sure to contact us. We believe we can provide you with better selection services.

Flash Voice Chips
Product Overview
The WTN6 F series is a cost-effective, high-performance CMOS voice chip. Its standout feature is its reprogrammable capability. Currently available models include the WTN6020-8S-F-B with a voice length of 20 seconds and the WTN6040-8S-F-B with a voice length of 40 seconds. The WTN6040-8S-F-B supports downloader replacement and offers 100KB of voice storage space. The audio sampling rate can reach up to 32kHz, with 16-level volume control and PWM output. The chip operates within a wide voltage range of 1.8V to 5.5V.
Considerations for selection:
1. Due to the need for a certain initialization time (approximately 100 milliseconds) when WTN6 powers up, it cannot respond to commands during initialization. Normal reception of control commands can only occur after initialization is complete.
2. Using 4R speakers or parallel-connected speakers may cause the chip’s PWM to experience latch-up, preventing playback. This issue requires re-powering to resolve and could potentially damage the chip.
