Product Overview
The ADXL345BCCZ-RL7 is a small, thin, ultra-low power, 3-axis MEMS accelerometer engineered by Analog Devices Inc. It features high-resolution (13-bit) measurement scaling up to ±16g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3-wire or 4-wire) or an I²C digital interface. This device is ideally suited for mobile device applications because it measures both the static acceleration of gravity in tilt-sensing configurations, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables the resolution of inclination changes of less than 1.0°. Several special sensing functions are provided, including tap/double-tap detection, activity/inactivity monitoring, and free-fall sensing. An integrated 32-level FIFO buffer unburdens the host processor, reducing overall system power consumption significantly. Supplied on a 7-inch tape and reel configuration, the is housed in a compact, low-profile LGA-14 (3x5x1.0mm ) package.
Core Advantages
Ultra-Low Power Consumption
Operates with current draw as low as 23 µA in full measurement mode and 0.1 µA in standby mode at Vs = 2.5V, making it an exceptional option for battery-constrained mobile and wearable electronic devices.
Flexible High-Resolution Architecture
Maintains a constant 3.9 mg/LSB resolution across all measurement ranges (±2g, ±4g, ±8g, ±16g), allowing precision tilt and threshold monitoring even at maximum scale selection.
Intelligent Hardware Event Detection
Natively flags active motion thresholds like single/double clicks, sharp impact shocks, static posture tilting, and structural free-fall transitions directly via two independent, programmable interrupt pins.
Integrated 32-Level FIFO Storage
Features an autonomous embedded FIFO data buffer that caches acceleration data samples, minimizing host microcontroller interrupt overhead and allowing the master system processor to remain longer in a low-power sleep state.

Frequently Asked Questions
Q1: Is your current stock inventory of the ADXL345BCCZ-RL7 genuine and original?
A: Yes, we guarantee that all ADXL345BCCZ-RL7 accelerometers in our stock are 100% brand-new, original factory components from Analog Devices Inc., handled and stored under strict anti-static ESD shielding and dry-pack moisture-control standards.
Q2: What is the specific packaging format implied by the “-RL7” suffix string?
A: The “-RL7” suffix stands for a 7-inch Tape and Reel packaging standard. This is optimized for high-speed automated pick-and-place surface mount (SMT) manufacturing assembly lines.
Q3: How does the internal 32-level FIFO buffer lower energy use on the main CPU board?
A: The FIFO sensor automatically stores incoming x, y, and z axis samples internally. Instead of prompting the master microcontroller for every data frame, it triggers an interrupt only when the buffer fills up, allowing the host CPU to stay in a low-power sleep mode for longer intervals.
Q4: How can our engineering group acquire specific reference code examples, layout advice notes, or volume quote options?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
