HT82A832R
Overview
The HT82A832R is an 8-bit high performance RISC-like microcontroller designed for USB Phone product applications. The HT82A832R combines a 16-bit PCM ADC, USB transceiver, SIE (Serial Interface Engine), audio class processing unit, FIFO and an 8-bit MCU into a single chip.
- Operating voltage: fSYS = 6M/12MHz: 4.0V~5.5V
- 24 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
