The ADuC7019 / ADuC7020 / ADuC7021 / ADuC7022 / ADuC7024 / ADuC7025 / ADuC7026 / ADuC7027 / ADuC7028 / ADuC7029 are fully integrated,1 MSPS, 12-bit data acquisition systems incorporating highperformance multichannel ADCs, 16-bit/32-bit MCUs, andFlash®/EE memory on a single chip.The ADC consists of up to 12 single-ended inputs. An additionalfour inputs are available but are multiplexed with the four DACoutput pins. The four DAC outputs are available only on certainmodels (ADuC7020, ADuC7026, ADuC7028, and ADuC7029).However, in many cases where the DAC outputs are not present,these pins can still be used as additional ADC inputs, giving amaximum of 16 ADC input channels. The ADC can operate insingle-ended or differential input mode. The ADC input voltageis 0 V to VREF. A low drift band gap reference, temperature sensor,and voltage comparator complete the ADC peripheral set.Depending on the part model, up to four buffered voltageoutput DACs are available on-chip. The DAC output range isprogrammable to one of three voltage ranges.The devices operate from an on-chip oscillator and a PLLgenerating an internal high frequency clock of 41.78 MHz(UCLK). This clock is routed through a programmable clockdivider from which the MCU core clock operating frequencyis generated. The microcontroller core is an ARM7TDMI®,16-bit/32-bit RISC machine, which offers up to 41 MIPS peakperformance. Eight kilobytes of SRAM and 62 kilobytes ofnonvolatile Flash/EE memory are provided on-chip. TheARM7TDMI core views all memory and registers as a singlelinear array.On-chip factory firmware supports in-circuit serial downloadvia the UART or I2C serial interface port; nonintrusive emulationis also supported via the JTAG interface. These features areincorporated into a low cost QuickStart™ development systemsupporting this MicroConverter® family.The parts operate from 2.7 V to 3.6 V and are specified over anindustrial temperature range of −40°C to +125°C. Whenoperating at 41.78 MHz, the power dissipation is typically120 mW.

The ADuC816 is a complete smart transducer front-end, integratingtwo high-resolution sigma-delta ADCs, an 8-bit MCU,and program/data Flash/EE Memory on a single chip. This lowpower device accepts low-level signals directly from a transducer.The two independent ADCs (Primary and Auxiliary) include atemperature sensor and a PGA (allowing direct measurement oflow-level signals). The ADCs with on-chip digital filtering areintended for the measurement of wide dynamic range, lowfrequency signals, such as those in weigh scale, strain gauge,pressure transducer, or temperature measurement applications.The ADC output data rates are programmable and the ADCoutput resolution will vary with the programmed gain andoutput rate.The device operates from a 32 kHz crystal with an on-chip PLLgenerating a high-frequency clock of 12.58 MHz. This clock is,in turn, routed through a programmable clock divider from whichthe MCU core clock operating frequency is generated. Themicrocontroller core is an 8052 and therefore 8051-instructionset-compatible.The microcontroller core machine cycle consistsof 12 core clock periods of the selected core operating frequency.8 Kbytes of nonvolatile Flash/EE program memory are providedon-chip. 640 bytes of nonvolatile Flash/EE data memory and256 bytes RAM are also integrated on-chip.The ADuC816 also incorporates additional analog functionalitywith a 12-bit DAC, current sources, power supply monitor,and a bandgap reference. On-chip digital peripherals include awatchdog timer, time interval counter, three timers/counters,and three serial I/O ports (SPI, UART, and I2C-compatible).On-chip factory firmware supports in-circuit serial download anddebug modes (via UART), as well as single-pin emulation modevia the EA pin.The part operates from a single 3 V or 5 V supply. When operatingfrom 3 V supplies, the power dissipation for the part is below10 mW. The ADuC816 is housed in a 52-lead MQFP package.The part operates from a single 3 V or 5 V supply.
