BMA222E Equivalent & Substitute Parts

Part Overview

The BMA222E is a digital accelerometer manufactured by Bosch Sensortec, designed for motion sensing applications requiring three-axis acceleration measurement. This device operates across multiple selectable acceleration ranges (±2g, ±4g, ±8g, ±16g) with configurable bandwidth and output protocols (I2C/SPI). The BMA222E is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production requirements. The LIS2DE12TR from STMicroelectronics serves as a direct substitute offering comparable electrical and mechanical specifications with active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BMA222E with the LIS2DE12TR is based on strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Identical package format: 12-LGA (2x2)
• Identical mounting type: Surface Mount
• Pin-to-pin compatible footprint

Electrical Functional Equivalence:

• Identical acceleration range options: ±2g, ±4g, ±8g, ±16g
• Identical axis configuration: X, Y, Z three-axis measurement
• Identical output protocols: I2C and SPI digital interfaces
• Overlapping supply voltage range: 1.62V ~ 3.6V (BMA222E) and 1.71V ~ 3.6V (LIS2DE12TR)
• Identical operating temperature range: -40°C ~ 85°C

Feature Compatibility:

• Both devices include adjustable bandwidth, selectable scale, and integrated temperature sensor
• Both support low power operation modes

The LIS2DE12TR extends bandwidth capability (0.5Hz ~ 2.69kHz versus 8Hz ~ 1kHz) and maintains active product status, making it suitable for direct replacement in new designs.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The LIS2DE12TR is the appropriate selection for new product development. The BMA222E obsolete status eliminates it from consideration for ongoing production. The LIS2DE12TR provides identical mechanical and core electrical functionality with extended bandwidth capability and active manufacturer support.

For Existing BMA222E Designs: Direct substitution of LIS2DE12TR is permissible where the following conditions are met:

1. Supply voltage range compatibility: Designs operating at 1.71V or higher can transition directly
2. Bandwidth requirements: Applications requiring bandwidth below 1kHz operate within LIS2DE12TR specifications
3. Sensitivity tolerance: Designs must accommodate the different LSB/g sensitivity at ±16g (5 LSB/g versus 8 LSB/g)
4. Moisture handling: LIS2DE12TR requires MSL 3 storage conditions (168 hours) versus unlimited for BMA222E

Compliance Considerations: The LIS2DE12TR carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic components in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can LIS2DE12TR replace BMA222E in existing PCB layouts?

A: Yes. Both devices use identical 12-LGA (2x2) packages with surface mount configuration. PCB footprints are compatible without modification.

Q: Are the I2C and SPI interfaces pin-compatible?

A: Both devices support I2C and SPI protocols. Pin assignments for these interfaces are identical, allowing direct firmware compatibility without hardware redesign.

Q: What is the impact of different sensitivity values at ±16g?

A: BMA222E provides 8 LSB/g at ±16g while LIS2DE12TR provides 5 LSB/g. This affects digital resolution at maximum acceleration range. Applications must recalibrate sensitivity coefficients in firmware or signal processing algorithms.

Q: Does the extended bandwidth of LIS2DE12TR (0.5Hz ~ 2.69kHz) affect compatibility?

A: The extended bandwidth is a superset of BMA222E capability (8Hz ~ 1kHz). Existing designs configured for 8Hz ~ 1kHz operation function identically. The additional bandwidth range is available for new applications but not required for existing implementations.

Q: What are the moisture sensitivity implications?

A: BMA222E has MSL 1 (unlimited shelf life). LIS2DE12TR has MSL 3 (168-hour limit after moisture exposure). Storage and handling procedures must follow MSL 3 requirements: sealed packaging, desiccant storage, and bake-out procedures before reflow soldering.

Q: Is firmware modification required for substitution?

A: Register maps and command structures differ between manufacturers. Firmware modifications are required to accommodate STMicroelectronics device-specific register definitions and initialization sequences. I2C/SPI communication protocols remain compatible.

Q: What is the supply voltage compatibility window?

A: BMA222E operates 1.62V ~ 3.6V; LIS2DE12TR operates 1.71V ~ 3.6V. Designs operating at 1.62V ~ 1.70V cannot use LIS2DE12TR. Designs at 1.71V and above are compatible with both devices.
