Manufacturer Documentation
Technical values were checked against Bosch Sensortec documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
BMA456 selection and design context
BMA456 is cataloged as a Accelerometer in the BMA456 family. Its recorded function is 16-bit high-performance digital triaxial accelerometer for wearable and hearable applications. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Resolution: 16 bit. Use the worst-case datasheet limit rather than a typical headline value.
- Measurement Ranges: ±2 g, ±4 g, ±8 g and ±16 g. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Digital Interface: I²C and SPI. Confirm logic levels, signaling mode, host support and required external components.
- Supply Voltage: 1.62 V to 3.6 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
Application and qualification considerations
When evaluating this sensor, confirm measurement range, sensitivity, noise, output data rate, interface voltage, calibration needs and mechanical orientation. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for BMA456
The recorded package is 12-land LGA, 2 mm × 2 mm × 0.65 mm, the temperature range is -40°C to +85°C, and the lifecycle status is Production as of 2026-07-18. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
BMA456 FAQ
What distinguishes BMA456 within the BMA456 family?
BMA456 is the exact orderable code for a 16-bit high-performance digital triaxial accelerometer for wearable and hearable applications in 12-land LGA, 2 mm × 2 mm × 0.65 mm. Related BMA456 devices may change package, rating, interface option or qualification grade, so compare the manufacturer ordering table before substitution.
What package and footprint checks are required for BMA456?
BMA456 is recorded in 12-land LGA, 2 mm × 2 mm × 0.65 mm with 12 pins, leads or contacts. Confirm the manufacturer package drawing, dimensions, pin numbering, exposed-pad requirements and packing suffix before releasing a PCB footprint.
Which specifications should be verified when selecting BMA456?
Resolution is recorded as 16 bit, Measurement Ranges is recorded as ±2 g, ±4 g, ±8 g and ±16 g. Use the latest datasheet for minimum and maximum limits, test conditions, timing and absolute maximum ratings rather than relying only on a distributor summary.
What is the lifecycle status of BMA456?
BMA456 was recorded as Production when verified on 2026-07-18. Reconfirm factory status, revision availability, lead time and any last-time-buy notice before design-in or volume procurement.
What information should be included in an RFQ for BMA456?
Provide the complete BMA456 orderable code, target quantity, acceptable date-code range, required packing method, delivery destination and documentation needs. For replacement work, also identify the existing package and any mandatory qualification grade.
How BMA456 differs from related orderable parts
BMA456 belongs to the BMA456 family. Compared with BMA422, the recorded differences include functional description: 16-bit high-performance digital triaxial accelerometer for wearable and hearable applications versus 12-bit low-power digital triaxial accelerometer with Android-oriented motion features; package: 12-land LGA, 2 mm × 2 mm × 0.65 mm versus 12-land LGA, 2 mm × 2 mm × 0.95 mm; and Resolution: 16 bit, a higher recorded value than 12 bit. A shared family name does not establish pin, firmware or qualification compatibility.
| Part number | Recorded function | Package | Pins / contacts | Temperature | Lifecycle |
|---|---|---|---|---|---|
| BMA456 | 16-bit high-performance digital triaxial accelerometer for wearable and hearable applications | 12-land LGA, 2 mm × 2 mm × 0.65 mm | 12 pins, leads or contacts | -40°C to +85°C | Production |
| BMA422 | 12-bit low-power digital triaxial accelerometer with Android-oriented motion features | 12-land LGA, 2 mm × 2 mm × 0.95 mm | 12 pins, leads or contacts | -40°C to +85°C | Production |
| BMA455 | 16-bit digital triaxial accelerometer with embedded wearable features | 12-land LGA, 2 mm × 2 mm × 0.95 mm | 12 pins, leads or contacts | -40°C to +85°C | Obsolete |
| BMA400 | ultra-low-power digital triaxial accelerometer with activity recognition | 12-land LGA, 2 mm × 2 mm × 0.95 mm | 12 pins, leads or contacts | -40°C to +85°C | Production |
For an RFQ or AVL review, quote the complete BMA456 code and verify the manufacturer ordering table, package drawing, packing method and revision. The related numbers above are comparison references, not declared drop-in replacements.
Exact order-code identity for BMA456
For BOM, label, AVL and RFQ matching, preserve these visible code segments: opening alphabetic sequence BMA and terminal numeric sequence four five six. The nearest published comparison codes are BMA422; BMA455; and BMA400. Compare every segment because a changed character can identify a different density, voltage, package, temperature, qualification or packing option.
Do not shorten the requested code to BMA456 or remove its terminal characters. Ask the supplier to reproduce the complete code on the quotation and provide label or traceability evidence when exact suffix matching is mandatory.
