WT588F02BP-14S Datasheet
■WT588F02BP-14S is a high-power voice chip developed by Shenzhen Weichuang Zhiyin Electronic Co., Ltd. It features PWM audio output and an integrated Class D audio power circuit capable of directly driving a 4-ohm 3W speaker. Its output functions without the need for LC filtering, ensuring normal operation. The chip reduces EMI interference across the entire bandwidth range, minimizing its impact on other components. Currently, WT588F02BP-14S supports a maximum of 170 seconds of voice content with higher audio quality (for customers with no specific audio quality requirements, it can support up to 320 seconds of voice content). Distinguished from traditional voice chips, WT588F02BP-14S allows online replacement of internal voice content through a compatible downloader. The chip supports one-wire and two-wire serial communication.
●Brief Function Description
■Operating voltage: 2.5V~5.5V (for proper amplifier operation, it is recommended not to go below 3.0V).
■Audio output method: 16-bit PWM.
■Directly drives 4-ohm 3W@5V speaker.
■Supports audio playback with sampling rates from 6K to 32KHz.
■Customers can replace internal voice content using a compatible downloader.
■Supports one-wire and two-wire serial communication.
■Maximum support for 1000 addressable voice segments.
■Built-in 220KB Flash, allowing for a maximum of 170 seconds of high-quality voice.
■Flash-type voice chip, both chip control program and Flash data are rewritable.
■Chip's power-up initialization time is approximately 200ms.
■After playback completion, the chip enters sleep mode 1 second after maintaining a stable level (either high or low) on IO ports (DATA and CLK).
■The chip includes a Class D audio power circuit with an efficiency of up to 88%, eliminating the need for filters.
■Built-in short-circuit protection, overcurrent protection, and overheat protection.
■Outstanding EMI suppression capability across the entire bandwidth.
■Excellent "power-up/power-down" noise suppression.
■Note: The PA2 pin of the chip is normally low and becomes high during playback.
