Analog Devices Inc. ADUC7023BCPZ62I-R7

Overview

ADUC7023BCPZ62I-R7 from Analog Devices is a precision analog microcontroller integrating an ARM7TDMI core, 12-bit 1 MSPS ADC (up to 12 channels), four 12-bit DAC outputs, on-chip temperature sensor, and 62 kB Flash/8 kB SRAM - designed for high-accuracy sensor signal acquisition and closed-loop control in harsh industrial environments.

For engineers reviewing the ADUC7023BCPZ62I-R7 datasheet, ADUC7023BCPZ62I-R7 pinout, ADUC7023BCPZ62I-R7 application, or ADUC7023BCPZ62I-R7 equivalent, this part supports I²C master/slave, SPI (20 Mbps master), 16-bit PWM, programmable logic array (PLA), and operates across −40°C to +125°C with 3 V supply and 5 V-tolerant GPIOs.

Technical Context

The ADUC7023BCPZ62I-R7 implements a fully integrated data acquisition system where the 12-bit ADC operates in single-ended or differential mode with 0 V to VREF input range and ±0.6 LSB INL (typ), while its four DACs support dual output voltage ranges (0–2.5 V or 0–AVDD) and retain output voltage during watchdog/software reset.

Its ARM7TDMI core runs at up to 41.78 MHz via internal PLL, features vectored interrupt controller (VIC) with 8 priority levels per IRQ/FIQ, JTAG debug, and in-circuit reprogrammability - all within a 32-lead 5 mm × 5 mm LFCSP package rated for industrial temperature operation.

FAQ

What is the maximum ADC sampling rate supported by the ADUC7023BCPZ62I-R7?

The ADUC7023BCPZ62I-R7 supports a maximum ADC sampling rate of 1 MSPS (1 million samples per second) with 12-bit resolution. This rate is achievable in single-ended mode across up to 12 channels or differential mode across up to 6 channels, as confirmed in the Rev. H datasheet Table 1 under "ADC CHANNEL SPECIFICATIONS." The ADC maintains ±0.6 LSB integral nonlinearity (typ) at this rate using the internal 2.5 V reference.

Does the ADUC7023BCPZ62I-R7 support 5 V logic interfaces?

Yes, the ADUC7023BCPZ62I-R7 supports 5 V-tolerant digital inputs on all P0.x GPIO pins, allowing direct connection to 5 V peripherals without level shifters. This is explicitly stated in the "Features" section and verified in Table 1 under "DIGITAL INPUTS," where VIH is specified up to 5 V. However, AVDD and IOVDD must remain within 2.7 V to 3.6 V.

Can the ADUC7023BCPZ62I-R7 retain DAC output voltage during a system reset?

Yes, the ADUC7023BCPZ62I-R7 DAC outputs retain their programmed voltage during both watchdog timer resets and software-initiated resets. This behavior is documented in the "GENERAL DESCRIPTION" section and confirmed in the DAC functional description: "The DAC outputs have an enhanced feature of being able to retain their output voltage during a watchdog or software reset sequence."

What is the operating temperature range for the ADUC7023BCPZ62I-R7?

The ADUC7023BCPZ62I-R7 is fully specified for operation from −40°C to +125°C, as stated in both the "Features" and "Packages and temperature range" sections of the Rev. H datasheet. This rating applies to all electrical specifications including ADC linearity, DAC accuracy, and Flash memory endurance, making it suitable for under-hood automotive and industrial edge applications.

How many I²C interfaces does the ADUC7023BCPZ62I-R7 include, and what modes do they support?

The ADUC7023BCPZ62I-R7 integrates two fully I²C-compatible serial interfaces (labeled I²C0 and I²C1), each configurable independently as master or slave. Both support standard mode (100 kHz) and fast mode (400 kHz), with timing parameters validated per Tables 2 and 3 in the Rev. H datasheet. Pins P1.6/SCL1 and P1.7/SDA1 are dedicated to I²C1, while P0.0/SCL0 and P0.1/SDA0 serve I²C0.
