WTN6 F series are low-cost, high-performance CMOS voice chips. The biggest feature is that it can be reprogrammed repeatedly. The existing WTN6020-8S-F-B with a voice length of 20s and the WTN6040-8S-F-B with a voice length of 40s. The WTN6040-8S-F-B supports downloader replacement and has a voice space of 100KB. The audio sampling rate is currently up to 32kHz, 16-level volume control, and PWM output. The chip works in a wide voltage range of 1.8V~5.5V.

Customized PCBA Requirements

Waytronic’s ability is built on a professional foundation in voice solutions. We specialize in various voice chip, as well as hardware component design, manufacturing, and selection. We also provide customers with PCBA manufacturing and complete voice solutions. Overall, chip design, manufacturing, and sales are our core businesses, and our resources and energy are limited. We need to be responsible for every customer’s project, especially customized projects involving PCBA design and manufacturing. Therefore, we need to clarify the following information:
