ADUC841:  Precision Analog Microcontroller: 20MIPS 8052 Flash MCU + 8-Ch 12-Bit ADC + Dual 12-Bit DAC

Product Details


The ADuC841 MicroConverter® is a fully integrated 12-bit data acquisition system-on-a-chip and is a higher speed-core (single cycle) upgrade to the existing ADuC812 and ADuC831. Like all of ADI's MicroConverter products, it features precision A/D & D/A conversion and a Flash microcontroller on a single chip.

It is available in 52-pin PQFP or 56-pin CSP packages and operates on a 3V or 5V power supply.

FEATURES and BENEFITS

  • 8-Channel, 400kSPS, Self-Calibrating, 12-Bit ADC
  • Two 12-Bit Rail-to-Rail Voltage-Output DACs
  • Two Flexible PWM Outputs /16-Bit ΣΔ DACs
  • Single Cycle 16MIPS 8052 Core
  • 62K-Byte In-Circuit Re-Programmable Flash Program Memory
  • 4K-Byte Read/Write Accessible Non-Volatile Flash Data Memory
  • 2K-Byte SRAM (In Addition to the 256-Bytes in the 8052 Core)
  • Temperature Monitor
  • Precision Voltage Reference
    (20ppm/°C), Serial Interface Ports
    (UART, I2C & SPI), Watchdog
    Timer, Time Interval Counter (TIC),
    Power Supply Monitor,
    Power-On-Reset (POR), etc.
  • Embedded Download/Debug
    & Emulation Features
  • Pin-compatible upgrade to
    ADuC812 and ADuC831
