The ADuC841/ADuC842/ADuC843 are complete smart transducer front ends, that integrates a high performance self-calibrating multichannel ADC, a dual DAC, and an optimized single-cycle 20 MHz 8-bit MCU (8051 instruction set compatible) on a single chip.

The ADuC841 and ADuC842 are identical with the exception of the clock oscillator circuit; the ADuC841 is clocked directly from an external crystal up to 20 MHz whereas the ADuC842 uses a 32 kHz crystal with an on-chip PLL generating a programmable core clock up to 16.78 MHz.

The ADuC843 is identical to the ADuC842 except that the ADuC843 has no analog DAC outputs.

The microcontroller is an optimized 8052 core offering up to 20 MIPS peak performance. Three different memory options are available offering up to 62 kBytes of nonvolatile Flash/EE program memory. Four kBytes of nonvolatile Flash/EE data memory, 256 bytes RAM, and 2 kBytes of extended RAM are also integrated on-chip.

The parts also incorporate additional analog functionality with two 12-bit DACs, power supply monitor, and a band gap reference. On-chip digital peripherals include two 16-bit Σ-Δ. DACs, a dual output 16-bit PWM, a watchdog timer, a time interval counter, three timers/counters, and three serial I/O ports (SPI, I2C, and UART).

On the ADuC812 and the ADuC832, the I2C and SPI interfaces share some of the same pins. For backwards compatibility, this is also the case for the ADuC841/ADuC842/ADuC843.

However, there is also the option to allow SPI operate separately on P3.3, P3.4, and P3.5, while I2C uses the standard pins. The I2C interface has also been enhanced to offer repeated start, general call, and quad addressing.

On-chip factory firmware supports in-circuit serial download and debug modes (via UART) as well as single-pin emulation mode via the EA pin..

Product Detail

Development systems for evaluation of the following products:

  • ADuC841 - 8-Channel 12-Bit ADC + Dual 12-Bit DAC + 20 MIPS Flash MCU 
  • ADuC842 - 8-Channel 12-Bit ADC + Dual 12-Bit DAC + 16 MIPS Flash MCU
  • ADuC843 - 8-Channel 12-Bit ADC + 16 MIPS Flash MCU

The QuickStart Kits for the ADuC8x-series (8052-core) Precision Analog Microcontrollers feature serial-port download/debug capability and an assembly-source debugging environment.


ADI also provides a non-intrusive emulation POD called the USB-EA-CONVZ allowing assembly & C-source debugging. The QuickStart Plus includes the POD (USB-EA-CONVZ) or it can be ordered separately.
