Analog Devices Inc. ADUC7022BCPZ32-RL

Overview

ADUC7022BCPZ32-RL from Analog Devices is a precision analog microcontroller integrating an ARM7TDMI core, 12-bit 1 MSPS ADC with up to 10 single-ended channels (ADC0–ADC9), on-chip temperature sensor (±3°C accuracy), and 4 general-purpose timers. It operates at up to 41.78 MHz, consumes 40 mA at full speed, and targets industrial sensor conditioning and closed-loop control where mixed-signal integration and deterministic timing are critical.

For engineers reviewing the ADUC7022BCPZ32-RL datasheet, ADUC7022BCPZ32-RL pinout, ADUC7022BCPZ32-RL application, or ADUC7022BCPZ32-RL equivalent, this page delivers verified specifications, package mapping, functional block context, real-world use cases, and validated alternative options - all grounded in Rev. H datasheet and official ordering guide data for the ADuC7022 variant.

Technical Context

The ADUC7022BCPZ32-RL implements a 12-bit SAR ADC with fully differential or single-ended input modes, 0 V to VREF input range, and ±1.5 LSB INL (typ.) using the internal 2.5 V reference. Its ARM7TDMI core executes Thumb/ARM instructions at 41.78 MHz via a PLL-driven clock system with programmable divider, enabling deterministic interrupt latency and real-time peripheral control.

On-chip analog peripherals include a band gap voltage reference (±40 ppm/°C drift), voltage comparator with configurable hysteresis (2–15 mV), and power supply monitor with dual trip points (2.79 V / 3.07 V). Digital resources comprise UART, dual I²C, SPI, 40-pin GPIO, and a programmable logic array (PLA) for custom signal routing - all mapped to a 32-lead LFCSP package.

FAQ

What is the maximum number of analog input channels supported by the ADUC7022BCPZ32-RL?

The ADUC7022BCPZ32-RL supports up to 10 dedicated single-ended analog inputs (ADC0 through ADC9), as confirmed in Figure 4 (Functional Block Diagram) and the General Description section of Rev. H datasheet. These pins are not shared with DAC outputs - unlike ADuC7020/26/28/29 - ensuring full 10-channel acquisition capability without multiplexing trade-offs.

Does the ADUC7022BCPZ32-RL include integrated DAC outputs?

No, the ADUC7022BCPZ32-RL does not include integrated DAC outputs. Per the Functional Block Diagram (Figure 4), datasheet Table 1 (Ordering Guide), and General Description, DAC functionality is excluded from the ADuC7022 variant - distinguishing it from ADuC7020, ADuC7024, ADuC7026, ADuC7028, and ADuC7029 models which offer 2–4 DAC channels.

What package type and dimensions does the ADUC7022BCPZ32-RL use?

The ADUC7022BCPZ32-RL uses a 32-lead LFCSP (Lead Frame Chip Scale Package) measuring 5 mm × 5 mm with an exposed thermal pad (EPAD). This is explicitly stated in the "Packages and temperature range" feature list and confirmed in the Outline Dimensions section (Page 98) of Rev. H datasheet - distinct from the 40-lead or 80-lead packages used by other ADuC70xx variants.

Is the on-chip temperature sensor in the ADUC7022BCPZ32-RL calibrated, and what is its accuracy?

Yes, the ADUC7022BCPZ32-RL includes a factory-calibrated on-chip temperature sensor with ±3°C accuracy across the full −40°C to +125°C operating range, as specified in the Features list and General Description. Its output is 780 mV at 25°C with a temperature coefficient of −1.3 mV/°C, enabling direct use for thermal compensation without external calibration.

What communication interfaces are available on the ADUC7022BCPZ32-RL?

The ADUC7022BCPZ32-RL provides UART, two I²C-compatible interfaces, and SPI serial I/O - all accessible via GPIO multiplexing. This is documented in the Features list, Functional Block Diagram (Figure 4), and Detailed Block Diagram (Figure 11). No CAN, USB, or Ethernet interfaces are integrated; those require external controllers or PHYs.
