Different from the previous OTP and Mask methods, HOLTEK Semiconductor has launched the Flash type voice IC HT83Fxx series. Although the general OTP voice IC can be burned in real time, it cannot be changed after the burn. The HT83Fxx series can not only be burned repeatedly, but even after the IC is soldered to the board, the voice content can still be modified through the SPI interface. Moreover, more and more home appliances need to add voice functions, especially the demand for multi-language often confuses customers with changing voice content. The HT83Fxx, which is based on Flash memory, transforms voice content very easily, and can solve the problems of multi-language and production inventory in the past.

HT83Fxx includes HOLTEK 8-bit microcontroller, built-in Flash Voice ROM, high-speed SPI and I2C interface, single-tone 12-bit voltage DAC, PWM directly pushes 8/16 ohm speakers, voice capacity ranges from 32 seconds to 512 seconds. With very few external parts, excellent noise immunity and industrial temperature range (-40 ° C ~ +85 ° C), the product introduction of voice function becomes more reliable and simpler.
The HT83Fxx series provides high-end software and hardware development tools (EasyPlayTM). It has built-in multiple popular voice playback modes and is equipped with HOLTEK's new generation of USB burners (e-Writer), which is easy to use and easy to burn. There is also a series of HT83FxxP with built-in 3.3V regulated line. Applications such as home protection, anti-theft devices, health care, and voice appliances provide a fast and reliable voice IC solution for generations that require a small amount of diversification and fast delivery.
