Application framework
Chip description
WT588F02B-8S is the latest 16-bit DSP voice chip developed by Guangzhou Waytronic Electronics Co., Ltd., featuring an internal oscillator of 32 MHz and 16-bit PWM decoding. Its powerful functions make the WT588F02B-8S stand out in the voice chip industry. Currently, as a voice chip, the WT588F02B-8S supports up to 170 seconds of audio content (if customers do not require high sound quality, it can support up to 320 seconds of audio content). Unlike traditional OTP chips, the biggest breakthrough of the WT588F02B-8S is that customers can achieve online replacement of internal voice content through accompanying downloaders; moreover, the chip is equipped with various resources such as hardware SPI, UART, IIC, and comparators, allowing for the customization of various personalized functional products.
WT588F02B It has rich sound and excellent midi sound effects, and the decoding function of EV1527 encoding format makes the design of wireless doorbell products simpler and faster.
