The WT WT588H16-16S is an industrial-grade, 8-pin voice record and playback IC manufactured by WT. It offers support for various SPI Flash memory types, ranging from 4Mbit to 128Mbit, allowing for flexible storage of audio data. The chip supports common audio formats like WAV and MIDI, with ADPCM decoding at 12-bit resolution (4K~16Khz) and PCM decoding up to 30Khz.
Designed for ease of integration, the WT588H16-16S features PWM output capable of directly driving an 8Ω, 0.5W speaker. It operates within a supply voltage range of 2.4V to 3.6V for both the chip and the external Flash memory. Key electrical characteristics include a low standby current of less than 5uA and a power-on initialization time of approximately 150ms. The chip supports up to 1000 voice address segments and enters a low-power sleep mode after 1 second of inactivity post-playback.
This voice IC is suitable for a wide array of applications, including smart locks, measurement devices, small home appliances, automotive electronics, toys, massage instruments, and various alarm systems. Its ability to be reprogrammed via a host computer makes it a versatile solution for products requiring custom voice prompts or audio feedback.
