Holtek has introduced two HT82A822R USB Speaker OTP MCUs and HT82A821R Basic USB Speaker OTP MCUs (Basic).
The HT82A822R integrates USB 1.1 SIE and digital-to-analog converters with built-in high-power amplifiers and an embedded microcontroller to provide a user-friendly design and manufacturing platform. The main feature of the product is that after the music played by the user is spectrally converted, the spectrum size value is displayed on the LCD, and the backlight color can be changed, so that the user can feel the shock of the music playing and the visual enjoyment.
The HT82A822R uses the Holtek eight-bit microcontroller as its core, providing 4Kx15 of program memory, 192x8 of data memory, and 512x8 of read-only data memory, and provides HALT instructions. Its operating voltage is 4.2V~5.5V, the maximum frequency can reach 12MHz. This chip can provide 24 I/O at the same time, which is a dedicated microcontroller of USB Speaker series.
In addition to integrating USB 1.1 SIE and digital-to-analog converters, the HT82A821R features a built-in high-power amplifier and an embedded microcontroller to provide a user-friendly design and manufacturing platform.
The HT82A821R uses Holtek's eight-bit microcontroller as its core, providing 2Kx15 of program memory and 192x8 RAM, as well as HALT instructions. Its operating voltage is 4.2V~5.5V, the maximum frequency can reach 12MHz. This chip can provide 8 I/O at the same time, which is a dedicated microcontroller of USB Speaker series.
Both products can use the One Time Programming (OTP) feature to extend a variety of applications and create product diversity.
The excellent features of the HT82A822R and HT82A821R, along with complete development tools and burners, provide developers with great convenience and can quickly design a wide range of customized products.
