Product details
Overview
SP300V21E1060XT from Infineon Technologies is a monolithic tire pressure and temperature sensor IC with integrated RF transmitter, designed for direct mounting inside automotive tires. It measures absolute pressure (100–1400 kPa), temperature (−40°C to +125°C), and supplies 3-axis acceleration data, operating at 315/433 MHz ISM bands with 10 dBm output power.
For engineers reviewing the SP300V21E1060XT datasheet, SP300V21E1060XT pinout, SP300V21E1060XT application, or SP300V21E1060XT equivalent, key selection criteria include integrated MEMS sensing elements, ASK/FSK modulation capability, low-power wake-up via acceleration trigger, and AEC-Q100 Grade 2 qualification for under-wheel deployment.
Technical Context
This sensor integrates a piezoresistive pressure sensing element, CMOS temperature sensor, and capacitive 3-axis accelerometer on a single die. Signal conditioning, ADC conversion, digital processing, and RF transmission are performed internally without external microcontroller dependency.
The device supports programmable transmission intervals (1–60 s), configurable wake-up thresholds per axis, and built-in self-test (BIST) for pressure and temperature sensors. Data packet structure includes CRC-8 checksum and unique ID for vehicle-level pairing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 100–1400 kPa full-scale range; covers all passenger and light-truck tire inflation requirements including overpressure tolerance. |
| Temperature Range | −40°C to +125°C operational range; validated for direct tire cavity mounting with thermal shock resistance. |
| RF Output Power | +10 dBm at 433 MHz; enables reliable signal reception at ≥10 m distance through rubber and wheel metal structures. |
| Supply Voltage | 2.1–3.6 V; compatible with standard lithium manganese dioxide coin-cell batteries (e.g., CR1632) for >7-year lifetime. |
| Wake-up Trigger | Programmable 3-axis acceleration threshold (±0.5g to ±8g); eliminates continuous RF transmission during static conditions. |
| Modulation | ASK/FSK selectable; supports legacy TPMS receiver compatibility and improved noise immunity in multi-vehicle environments. |

Applications
| Direct-Mount TPMS | OEM Tire Assembly Line Integration |
|---|---|
Use Scenario: Sensor mounted directly on tire valve stem or inner liner during manufacturing. IC Role / Device Role / Timing Role: Primary pressure/temperature/acceleration measurement and RF telemetry node with autonomous wake-up. Use Value: Eliminates need for external MCU or RF front-end; reduces BOM count by 3 components and assembly steps. | Use Scenario: Pre-programmed and calibrated units installed at tire plant before wheel mounting. IC Role / Device Role / Timing Role: Factory-configured sensor with unique ID, pressure offset trim, and transmission schedule preloaded. Use Value: Enables zero-field calibration; cuts service center setup time and eliminates post-installation learning procedures. |

IC Role / Device Role / Timing Role: Drop-in replacement with identical RF protocol and mechanical footprint as original equipment. Use Value: Supports standardized ISO 21898-1 message format and ETSI EN 300 220-1 compliance for regulatory acceptance. | Use Scenario: Integration into commercial truck telematics units for predictive maintenance alerts. IC Role / Device Role / Timing Role: Edge-sensing node feeding pressure trend data to gateway for flat-tire detection and load-balancing analysis. Use Value: Provides 0.5 kPa resolution enabling early detection of slow leaks (<0.5 psi/day) before safety thresholds are breached. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar tire pressure sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP MPXY8300 | Single-axis accelerometer only; 315 MHz only; no FSK option; requires external crystal. | Limited to basic pressure-only use cases without motion-triggered wake-up or dual-band flexibility. | Select when cost sensitivity outweighs motion-aware features and regional band support is fixed. |
| Sensata SC1x Series | Discrete MEMS + ASIC + RF chip set; larger PTH package; higher current consumption (12 μA avg vs. 8 μA). | Requires multi-component placement and additional board area; suited for retrofit modules rather than direct valve integration. | Prefer for legacy platform upgrades where board space and assembly process allow discrete implementation. |
Compared with MPXY8300 and SC1x Series, SP300V21E1060XT delivers integrated 3-axis wake-up, dual-band RF, and lower quiescent current-enabling longer battery life and broader deployment across global vehicle platforms without hardware redesign.

FAQ
What battery type and lifetime can be expected with SP300V21E1060XT?
The device is optimized for CR1632 lithium manganese dioxide coin cells. At default 60-second transmission interval and 25°C ambient, typical battery life exceeds 7 years. Lifetime scales inversely with transmission frequency and ambient temperature, with validated operation down to −40°C and up to +125°C junction temperature.
Does SP300V21E1060XT require an external crystal or oscillator?
No. The device integrates a temperature-compensated RC oscillator for system timing and RF carrier generation. An external crystal is neither required nor supported-this simplifies PCB layout and eliminates crystal-related failure modes in high-vibration environments.
How is pressure calibration handled during manufacturing?
Each unit undergoes individual pressure and temperature calibration at two points (25°C and 85°C) during final test. Calibration coefficients are stored in one-time-programmable (OTP) memory. No field recalibration is needed; offset and sensitivity drift remain within ±1.5 kPa over 10 years at 105°C.
Can SP300V21E1060XT coexist with other RF devices in the same vehicle?
Yes. Its FSK mode provides 25 kHz channel spacing and built-in CRC-8 error detection, supporting up to 32 simultaneous sensors per vehicle. Channel selection and preamble length are programmable to avoid interference with keyless entry or remote start systems operating in adjacent ISM bands.
