Analog Devices Inc. ADUC7024BCPZ62I-RL

Overview

ADUC7024BCPZ62I-RL from Analog Devices is a precision analog microcontroller integrating an ARM7TDMI core, 12-bit 1 MSPS ADC (10 single-ended + 2 multiplexed channels), dual 12-bit voltage-output DACs, on-chip temperature sensor (±3°C), and 3-phase PWM generator. It operates at up to 41.78 MHz with 62 kB Flash/EE and 8 kB SRAM, targeting high-accuracy industrial sensor conditioning and closed-loop motor control.

For engineers reviewing the ADUC7024BCPZ62I-RL datasheet, ADUC7024BCPZ62I-RL pinout, ADUC7024BCPZ62I-RL application, or ADUC7024BCPZ62I-RL equivalent, key selection criteria include its 12-bit ADC accuracy (±1.5 LSB INL), dual DAC output range options (0–VREF / 0–DACVDD), −40°C to +125°C operation, LFCSP-40 package, and integrated PLL clocking with programmable divider.

Technical Context

The ADUC7024BCPZ62I-RL implements a 12-bit successive-approximation ADC with fully differential or single-ended input modes, 0 V to VREF analog input range, and internal 2.5 V ±5 mV reference (±40 ppm/°C TC). Its dual 12-bit DACs support three programmable output voltage ranges and deliver ≤10 µs settling time with ±20 nV·sec glitch energy.

It features an ARM7TDMI RISC core running at up to 41.78 MHz via a 41.78 MHz PLL with programmable clock divider, 4 general-purpose timers, UART/I²C/SPI interfaces, 40-pin GPIO, and a 3-phase PWM block with six dedicated output pins (PWM0H/L, PWM1H/L, PWM2H/L). Power supply monitoring and wake-up timer support robust industrial operation.

FAQ

What is the ADC channel count and configuration supported by the ADUC7024BCPZ62I-RL?

The ADUC7024BCPZ62I-RL supports 12 dedicated ADC input channels: ADC0–ADC7 on P3.0–P3.7, and ADC8–ADC11 on P4.0–P4.3. Pins P4.4 and P4.5 are multiplexed with DAC0/DAC1 but are configured as ADC12/ADC13 only on models with DACs enabled; however, ADUC7024 does not implement DAC outputs on those pins per datasheet Figure 5 and Ordering Guide notes.

Does the ADUC7024BCPZ62I-RL include on-chip DAC outputs, and what are their specifications?

Yes, the ADUC7024BCPZ62I-RL integrates two 12-bit voltage-output DACs (DAC0 and DAC1) with programmable output ranges: 0–VREF, 0–2.5 V, or 0–DACVDD. Each delivers ±2 LSB relative accuracy, ±15 mV offset error, and ≤10 µs settling time into 5 kΩ//100 pF loads, as confirmed in the Rev. H datasheet Table 1 DAC specifications section.

What is the operating temperature range and supply voltage specification for the ADUC7024BCPZ62I-RL?

The ADUC7024BCPZ62I-RL is fully specified for operation from −40°C to +125°C and supports a single 2.7 V to 3.6 V supply across AVDD, IOVDD, and DVDD domains. This industrial-grade rating and wide supply range enable deployment in uncontrolled environments such as factory floors, outdoor telecom cabinets, and automotive under-hood applications.

How is the clock system structured in the ADUC7024BCPZ62I-RL, and what frequencies are achievable?

The ADUC7024BCPZ62I-RL uses an on-chip trimmed oscillator (±3%) feeding a 41.78 MHz PLL with a programmable clock divider. The resulting core clock can be scaled down to meet application requirements-from 5 MHz (11 mA active current) to the full 41.78 MHz (40 mA), enabling optimization of performance versus power consumption in battery- or thermally constrained designs.

Which communication interfaces are available on the ADUC7024BCPZ62I-RL, and how are they implemented?

The ADUC7024BCPZ62I-RL provides UART, two I²C-compatible interfaces, and SPI serial I/O-all accessible via GPIO multiplexing. These interfaces support in-circuit firmware download (UART/I²C), peripheral expansion (I²C/SPI), and host communication (UART), with JTAG retained exclusively for debug and emulation functions as documented in the Rev. H datasheet Section "Serial Port Mux".
