BMA250

BMA250 Overview

BMA250 is a Bosch Sensortec 10-bit digital triaxial low-g acceleration sensor supplied in 12-land LGA, 2 mm × 2 mm × 0.95 mm. This page uses the exact orderable code because package, grade, temperature and option suffixes can change compatibility.

Key Technical Specifications

Package and Ordering Notes

The listed package is 12-land LGA, 2 mm × 2 mm × 0.95 mm with 12 pins, leads, lands or contacts. The featured image is a generic package illustration for form-factor identification and is not an actual date-code or lot photograph. Lifecycle is recorded as Obsolete; confirm current factory support and last-time-buy constraints before design-in.

Sourcing Guidance

BMA250 is a legacy or obsolete orderable code. Source only with date-code, label, package and traceability checks appropriate to the application.

For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.

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.

BMA250 selection and design context

BMA250 is cataloged as a Accelerometer in the BMA250 family. Its recorded function is 10-bit digital triaxial low-g acceleration sensor. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.

• Resolution: 10 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 BMA250

The recorded package is 12-land LGA, 2 mm × 2 mm × 0.95 mm, the temperature range is -40°C to +85°C, and the lifecycle status is Obsolete 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.

BMA250 FAQ

How BMA250 differs from related orderable parts

BMA250 belongs to the BMA250 family. Compared with BMA280, the recorded differences include functional description: 10-bit digital triaxial low-g acceleration sensor versus 14-bit digital triaxial low-g acceleration sensor and Resolution: 10 bit, a lower recorded value than 14 bit. A shared family name does not establish pin, firmware or qualification compatibility.

For an RFQ or AVL review, quote the complete BMA250 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 BMA250

For BOM, label, AVL and RFQ matching, preserve these visible code segments: opening alphabetic sequence BMA and terminal numeric sequence two five zero. The nearest published comparison codes are BMA280; BMA250E; and BMA253. 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 BMA250 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.

BMA250 specification interpretation

The following notes interpret the recorded values for this exact orderable code. They are intended to make model-to-model differences visible during engineering and procurement review; the manufacturer datasheet remains the controlling source.

• Resolution: The recorded value is 10 bit, expressed in words as ten bit. Use the worst-case datasheet limit rather than a typical headline value. The comparison record for BMA280 lists 14 bit; this page therefore preserves 10 bit as the value associated with BMA250.
• Measurement Ranges: The recorded value is ±2 g, ±4 g, ±8 g and ±16 g, expressed in words as ±two g, ±four g, ±eight g and ±sixteen g. Confirm the value and its datasheet test conditions for the exact ordering suffix.
• Digital Interface: The recorded value is I²C and SPI. Confirm logic levels, signaling mode, host support and required external components.
• Supply Voltage: The recorded value is 1.62 V to 3.6 V, expressed in words as one point six two V to three point six V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
• Low-Power Current: The recorded value is 7 µA at 40 Hz typical, expressed in words as seven µA at forty Hz typical. Check steady-state, transient and thermal margin in the intended operating mode.
