Product details

Overview

ADUCM300WBCPZ from Analog Devices is an automotive-qualified, integrated precision sensor signal conditioner and LIN 2.2 slave node featuring dual 20-bit Σ-Δ ADCs (primary differential and auxiliary single-ended), Arm Cortex-M3 core (16.384 MHz, ±1% accuracy), on-chip 1.2 V reference, 128 kB Flash/EE with ECC, and embedded LIN transceiver compliant with SAE J2602. It operates from 3.6 V to 18 V and is fully specified from −40°C to +115°C for powertrain and chassis sensing.

For engineers reviewing the ADUCM300WBCPZ datasheet, ADUCM300WBCPZ pinout, ADUCM300WBCPZ application, or ADUCM300WBCPZ equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in automotive LIN sensor nodes, and validated alternative parts - all grounded in Rev. 0 datasheet specifications and AEC-Q100 qualification.

Technical Context

The ADUCM300WBCPZ integrates a primary 20-bit Σ-Δ ADC with programmable gain (4–512), digital comparator, and accumulator, plus an auxiliary 20-bit ADC with flexible mux for AIN4 (supply monitoring), AIN5 (external sensor/temperature), and internal die temperature sensing. Its LIN physical layer supports 1–20 kbps, meets SAE J2602, and features dominant/recessive thresholds tied to VDD (0.4×/0.6×VDD) with ±6 kV HBM ESD on LIN pin.

It combines a 16.384 MHz high-precision oscillator (±0.5% in 1% mode), 32 kHz low-power oscillator, LDO regulators for analog/digital domains, and peripherals including SPI, six GPIOs, WDT, wake-up timer, and POR with 3.1 V trip level. Power consumption is 8 mA typical at 16 MHz, dropping to <100 µA in hibernate mode with LIN active.

Equivalent & Alternatives

The following parts are listed as comparable options for similar precision automotive sensor interface applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUCM360BCPZ	Dual 24-bit Σ-Δ ADCs, no integrated LIN transceiver, higher resolution but requires external LIN PHY	Better suited for high-precision lab instrumentation or non-LIN industrial sensing; lacks AEC-Q100 qualification for automotive	Select when >20-bit resolution is mandatory and LIN can be added externally; not drop-in for ADUCM300WBCPZ's integrated LIN footprint
TLIN1029DSWR	Standalone LIN 2.2 transceiver only - no ADC, MCU, or reference; 5 V supply only	Used with external microcontroller (e.g., MSP430 or S32K1) for modular LIN node design; no signal conditioning capability	Choose when separating signal chain and communication layers is preferred; requires additional MCU, ADC, and voltage regulation

Compared with ADUCM300WBCPZ, ADUCM360BCPZ offers higher ADC resolution but lacks integrated LIN and automotive qualification, while TLIN1029DSWR provides only LIN PHY functionality - neither replicates the ADUCM300WBCPZ's single-chip, AEC-Q100-compliant sensor-to-bus solution.

FAQ

What is the operating temperature range qualified for ADUCM300WBCPZ?

The ADUCM300WBCPZ is fully specified and AEC-Q100 qualified for continuous operation from −40°C to +115°C. Additional characterization data confirms functional operation up to +125°C, though certain parameters like INL and offset drift degrade beyond +115°C per Table 1 in the Rev. 0 datasheet. This makes ADUCM300WBCPZ suitable for under-hood automotive applications including engine control and transmission modules.

Does ADUCM300WBCPZ include an integrated LIN transceiver or require an external one?

ADUCM300WBCPZ integrates a fully compliant LIN 2.2 slave transceiver meeting SAE J2602 requirements - no external LIN PHY is needed. The LIN pin (Pin 32) connects directly to the bus, supporting dominant/recessive signaling, ±6 kV HBM ESD protection, and voltage thresholds referenced to VDD (0.4×/0.6×VDD). This integration reduces PCB area, BOM cost, and design complexity versus discrete MCU + transceiver solutions.

What ADC input configurations does ADUCM300WBCPZ support?

ADUCM300WBCPZ supports two independent ADC subsystems: the primary ADC accepts differential inputs on AIN0/AIN1 with programmable gain (4–512) and absolute range −200 mV to +300 mV; the auxiliary ADC supports single-ended inputs on AIN4 (6–18 V supply monitoring), AIN5 (0–1.4 V external sensor), and internal temperature sensing. Both deliver 20-bit no-missing-codes performance across their respective ranges.

How is the on-chip voltage reference specified for ADUCM300WBCPZ?

The ADUCM300WBCPZ includes a factory-trimmed 1.2 V internal voltage reference with ±0.15% initial accuracy at 25°C, ±5 ppm/°C temperature coefficient, and 100 ppm/1000 hours long-term stability. It powers both ADCs and is enabled/disabled under software control. Reference buffer current is 150 µA typical, and power-up time is 0.5 ms - enabling fast, stable conversions without external reference components.

What memory resources are available on ADUCM300WBCPZ?

ADUCM300WBCPZ provides 128 kB of Flash/EE program memory, 4 kB of dedicated data Flash/EE memory, and 6 kB of SRAM - all protected by error-correcting code (ECC). Flash endurance is rated at 10,000 write/erase cycles, with 20-year data retention at 85°C junction temperature. In-circuit programming is supported via SWD and LIN interfaces, enabling field firmware updates without hardware rework.
