General Description
This HT82A525R is an 8-bit high performance RISC microcontroller designed for USB keyboard
mouse and fingerprint product applications.
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.
