Product details
Overview
ADXL362BCCZ-MI-RL7 from Analog Devices is an ultralow-power, 3-axis MEMS accelerometer with ±2 g/±4 g/±8 g selectable ranges, 12-bit resolution (1 mg/LSB on ±2 g), SPI interface, and true continuous sampling-no undersampling or aliasing. It operates from 1.6 V to 3.5 V, draws only 1.8 µA at 100 Hz ODR, and supports motion-triggered wake-up at 270 nA for battery-powered hearing aids and wireless sensors.
For engineers reviewing the ADXL362BCCZ-MI-RL7 datasheet, ADXL362BCCZ-MI-RL7 pinout, ADXL362BCCZ-MI-RL7 application, or ADXL362BCCZ-MI-RL7 equivalent, key selection criteria include guaranteed 12-bit output resolution across all ODRs, autonomous interrupt generation without MCU involvement, deep FIFO for burst data capture, low-noise modes down to 175 µg/√Hz, and integrated temperature sensor with 0.065 °C/LSB sensitivity.
Technical Context
The ADXL362BCCZ-MI-RL7 uses a polysilicon surface-micromachined capacitive sensing element with phase-sensitive demodulation, enabling true static (tilt) and dynamic acceleration measurement. Its digital architecture includes a 12-bit ADC, configurable antialiasing filter (½ or ¼ ODR), and autonomous activity/inactivity detection logic that operates independently of host intervention.
It implements three distinct power states: measurement mode (≤3.0 µA at 400 Hz), wake-up mode (270 nA at ~6 Hz activity check), and standby (10 nA). All modes retain register access and FIFO functionality except the activity timer in wake-up mode, and all support SPI communication and external trigger synchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Data Rate | 12.5–400 Hz user-selectable; enables precise tradeoff between latency and power without aliasing. |
| Power Consumption | 1.8 µA typical at 100 Hz / 2.0 V; allows >1-year operation on CR2032 coin cell in continuous monitoring. |
| Resolution & Sensitivity | 12-bit output; 1 mg/LSB on ±2 g range-enables sub-degree tilt resolution in portable healthcare devices. |
| Noise Density | 175 µg/√Hz in ultra-low-noise mode at 3.5 V-supports high-fidelity vibration analysis in low-amplitude applications. |
| Supply Range | 1.6 V to 3.5 V; I/O compatible with 1.6–3.3 V hosts-eliminates level-shifting in mixed-voltage embedded systems. |
| Temperature Sensor | On-chip, 12-bit, 0.065 °C/LSB sensitivity-provides calibrated thermal compensation without external components. |
| FIFO Depth | 512 × 16-bit entries-reduces host polling frequency and enables burst-mode data acquisition. |
Pinout & Package
ADXL362BCCZ-MI-RL7 is housed in a 3 mm × 3.25 mm × 1.06 mm, 16-terminal LGA package with exposed pad (θJA = 150°C/W). Pin 1 is marked with "•362B" on top surface; pins 2, 15 are NC; pins 3, 5, 10 are reserved (GND optional); pins 12, 13, 16 are GND; pin 14 is VS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD I/O (Pin 1) | Digital I/O supply rail | Independent from analog VS; allows interfacing with lower-voltage microcontrollers (1.6–3.3 V). |
| SCLK (Pin 4) | SPI clock input | Supports up to 5 MHz SCLK; timing-critical for deterministic interrupt latency and synchronized sampling. |
| MOSI (Pin 6) | SPI data input | Used for register writes, configuration commands, and self-test activation. |
| MISO (Pin 7) | SPI data output | Provides 16-bit aligned acceleration data, status flags, FIFO entries, and temperature readings. |
| CS (Pin 8) | SPI chip select (active low) | Enables multi-device SPI bus sharing; must be held low for entire transaction (min 50 ns pulse width). |
| INT1 (Pin 11) | Interrupt 1 output / external clock input | Configurable as motion-triggered wake signal or external timing reference for synchronized sampling. |
| INT2 (Pin 9) | Interrupt 2 output / sync trigger input | Supports dual-interrupt event handling (e.g., activity + FIFO full) or external sampling alignment. |
| VS (Pin 14) | Analog supply voltage | 1.6–3.5 V range powers sensor core and ADC; noise on VS directly impacts noise density and PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Autonomous motion detection | Adjustable threshold and time window for activity/inactivity; runs at 270 nA without MCU-enables zero-power system sleep. |
| Deep multimode FIFO | 512-entry buffer with watermark and overrun detection; reduces host processor wake-ups by >90% in intermittent sensing. |
| True continuous sampling | No duty cycling or undersampling-full sensor bandwidth sampled at all ODRs, eliminating aliasing artifacts in vibration diagnostics. |
| Awake-state output pin | Dedicated AWAKE signal indicates real-time motion status; drives external load switches directly for standalone motion-activated power control. |
| Configurable low-noise modes | Two selectable modes (400 µg/√Hz and 250 µg/√Hz at 2.0 V) with <2× current increase-preserves battery life while enhancing SNR. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-axis micropower accelerometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADXL372BCCZ-RL7 | Higher full-scale range (±200 g), lower resolution (12-bit but 12.5 mg/LSB), optimized for shock detection-not tilt or low-g motion. | Targeted at impact monitoring (e.g., drop testing), not healthcare or motion-switching. | Select only if measuring high-g transients; incompatible for sub-1 g applications like fall detection. |
| LSM6DSOXTR | Integrated 6-DoF IMU (gyro + accel), higher current (150 µA typical), no 270 nA wake-up mode, different SPI timing. | Requires full-system wake for any motion event; lacks autonomous low-power decision logic. | Choose when gyro data is essential; avoid if battery life >5 years or true autonomous wake-up is required. |
Compared with ADXL362BCCZ-MI-RL7, ADXL372BCCZ-RL7 trades low-g sensitivity for high-g robustness, while LSM6DSOXTR adds gyro functionality at 80× higher wake-current cost-making ADXL362BCCZ-MI-RL7 uniquely suited for ultra-long-life, motion-triggered, low-g sensing where autonomous decision-making is critical.

FAQ
What is the guaranteed minimum output data rate for ADXL362BCCZ-MI-RL7?
The ADXL362BCCZ-MI-RL7 guarantees a minimum output data rate of 12.5 Hz across its full operating temperature range (−40°C to +85°C) and supply voltage range (1.6 V to 3.5 V). This rate is achieved with HALF_BW = 0 and is fully supported in both measurement and wake-up modes, enabling reliable low-frequency motion tracking in sleep-state monitoring applications without aliasing.
Does ADXL362BCCZ-MI-RL7 support I²C interface?
No, ADXL362BCCZ-MI-RL7 supports SPI only-specifically a 4-wire interface (SCLK, MOSI, MISO, CS) with no I²C capability. The device requires active chip select assertion and supports multi-byte transfers with address auto-increment. I²C users must select alternative accelerometers such as the ADXL345 or ICM-20689.
Can ADXL362BCCZ-MI-RL7 operate from a 1.6 V supply while maintaining full 12-bit resolution?
Yes, ADXL362BCCZ-MI-RL7 maintains full 12-bit output resolution and specified noise performance (550 µg/√Hz typical) at 1.6 V supply. All registers, FIFO, interrupt logic, and temperature sensor remain fully functional. Current consumption increases slightly to ~2.0 µA at 100 Hz ODR, but remains within datasheet limits and retains compatibility with coin-cell and energy-harvesting sources.
How does the referenced activity detection mode work in ADXL362BCCZ-MI-RL7?
In referenced activity mode, ADXL362BCCZ-MI-RL7 calculates a dynamic baseline from initial stationary orientation, then detects motion only when acceleration deviates by more than a user-defined threshold from that baseline (|Acc − Reference| > Threshold). This eliminates false triggers from gravity (1 g static offset), making it ideal for tilt-insensitive motion switches in handheld medical devices where orientation varies.
Is the ADXL362BCCZ-MI-RL7 RoHS compliant and lead-free?
Yes, ADXL362BCCZ-MI-RL7 is RoHS compliant and lead-free. The package branding includes a "#" prefix (e.g., #yww in Table 4), indicating Pb-free construction per JEDEC J-STD-609. The device meets Analog Devices' environmental compliance standards, including exemption 7a for lead in high-melting-temperature solder alloys, and ships with standard SnAgCu (SAC305) finish.
