GENERAL DESCRIPTION

8051 compatible instruction set (20 MHz max)

High performance single-cycle core

32 kHz external crystal, on-chip programmable PLL

12 interrupt sources, 2 priority levels

Dual data pointers, extended 11-bit stack pointer

On-chip peripherals

Time interval counter (TIC)

UART, I²C®, and SPI® Serial I/O

Watchdog timer (WDT)

Power supply monitor (PSM)

The ADuC841/ADuC842/ADuC843¹are 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.

Power

Normal: 4.5 mA @ 3 V (core CLK = 2.098 MHz)

Power-down: 10 µA @ 3 V²

Development tools

Low cost, comprehensive development system

incorporating nonintrusive single-pin emulation,

IDE based assembly and C source debugging

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.

APPLICATIONS

Optical networking—laser power control

Base station systems

Precision instrumentation, smart sensors

Transient capture systems
