This HT82A525R is an 8-bit high performance RISC microcontroller designed for USB keyboard mouse and fingerprint product applications.\n\n The advantages of low power consumption, I/O flexibility, timer functions, oscillator options, multi-channel Pulse Width Modulation function, Watchdog timer, dual SPI interfaces, SPI serial DMA or 8-bit parallel DMA , Power Down and wake-up functions, combine to provide the device with a huge range of functional options while still maintaining a high level of cost effectiveness. The device includes a fully integrated system oscillator HIRC, which requires no external components. While the DMA function opens up application possibilities such as fingerprint data processing, the device is also suited for a range of other applications such as motor driving, industrial control, consumer products, subsystem controllers, etc.\n\n  \n\n
