HT82A851R - USB Audio MCU

Description

The HT82A851R is an 8-bit high performance RISC-like microcontroller designed for wireless USB Phone product applications.

The HT82A851R combines a SPI, USB transceiver, SIE (Serial Interface Engine), audio class processing unit, FIFO and an 8-bit MCU into a single chip.

Features

  • Operating voltage: fSYS = 6M/12MHz: 3.3V~5.5V.
  • 16 bidirectional I/O lines (max. ).
  • Two 16-bit programmable timer/event counters and.
  • Two hardware implemented Isochronous transfers.
  • Total FIFO size: 464 bytes (8, 8, 384, 32, 32 for EP0~EP4).
  • Programmable frequency divider (PFD).
  • Integrated SPI hardware circuit.
  • Play/Record Interrupt.
  • HALT and wake-up features reduce power overflow interrupts.
  • 4096´15 program memory ROM.
  • 384´8 data memory RA.
