Product details
Overview
TLE49SRC8XUMA1 from Infineon Technologies is a stray field robust, differential Hall-based magnetic angle sensor delivering 360° absolute angular position with ±1° intrinsic error over temperature (−40°C to +125°C) and lifetime, supporting SPC interface per ISO 26262 ASIL C(D) safety requirements, and used in automotive chassis height and steering angle sensing.
For engineers reviewing the TLE49SRC8XUMA1 datasheet, TLE49SRC8XUMA1 pinout, TLE49SRC8XUMA1 application, or TLE49SRC8XUMA1 equivalent, this page provides verified interface timing, stray field immunity (±8 mT DC / ±1.25 mT AC), EEPROM-configurable zero angle, 14-bit resolution (0.022°/bit), and SPC Frameholder mechanism details critical for functional safety integration.
Technical Context
The TLE49SRC8XUMA1 integrates spatially separated Hall cells with on-die CORDIC computation and digital signal processing to reject external magnetic interference while resolving absolute angle via differential field measurement. Its architecture includes analog regulators, digital clocking, SENT/PWM/SPC interface logic, and EEPROM-backed calibration LUT.
It operates from 4.5–5.5 V supply across −40°C to +125°C ambient, supports 30 V transient peaks (50 µs), withstands ±4 kV HBM ESD, and delivers angle speed information alongside position - all within PG-TDSO-8-1 package with single-wire SICI programming on the I/O pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Angle Accuracy | ±1° max intrinsic error over full temp/lifetime - enables direct use in ASIL-C chassis control without external correction. |
| Angular Resolution | 14-bit over 360° (0.022°/bit) - supports high-precision closed-loop feedback in throttle or pedal position systems. |
| Stray Field Immunity | ±8 mT DC / ±1.25 mT AC per ISO 11452-8:2015 Level IV - ensures reliable operation near motors, solenoids, or high-current traces. |
| Interface Protocol | SPC (Single-wire Pulse Code) with Frameholder - provides deterministic, low-latency angle updates synchronized to master trigger pulses. |
| Supply Voltage Range | 4.5–5.5 V - compatible with standard automotive 5 V domains and tolerant of battery transients up to 30 V (50 µs). |
| Operating Temperature | −40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and chassis-mounted applications. |
| Magnetic Field Range | 20–90 mT orthogonal field - optimized for common ferrite or NdFeB magnet geometries at air gaps typical in steering or suspension sensors. |
Pinout & Package
Package: PG-TDSO-8-1 (8-pin thin dual small outline, exposed thermal pad, RoHS/halogen-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I/O) | SPC data line / SICI programming | Bi-directional single-wire interface for angle output and EEPROM configuration; requires external pull-up. |
| 2 (CBuf) | Buffer capacitor connection | Connects external 100 nF ceramic capacitor to stabilize internal analog regulator; critical for noise immunity. |
| 3 (GND) | Analog/digital ground reference | Common return path for supply, Hall sensing, and interface; must be low-impedance to minimize offset drift. |
| 4 (VDD) | Primary power supply input | Accepts 4.5–5.5 V; supports 30 V transient peaks; internal protection limits current during reverse polarity events. |
| 5–8 (n.c.) | No connect | Unbonded pins; must remain unconnected and unpopulated on PCB to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| Differential Hall sensing | Two physically separated Hall elements enable common-mode rejection of stray fields - eliminates need for external shielding. |
| EEPROM-based LUT correction | On-chip 128-word lookup table compensates systematic angle errors from magnetic circuit asymmetry or magnet misalignment. |
| SPC Frameholder mechanism | Hardware-enforced synchronization ensures angle data validity during master-triggered read cycles - prevents metastability in real-time control loops. |
| SICI single-wire programming | Configuration (zero angle, measurement range, bus capability bits) written via I/O pin without dedicated programming interface - reduces BOM count. |
| ISO 26262 SEooC compliance | Validated as Safety Element out of Context up to ASIL C(D); includes diagnostic coverage for magnetic field out-of-range and supply faults. |
Applications
| Chassis Height Sensor | Pedal Position Sensor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE49SRP8XUMA1 | PWM interface instead of SPC; identical core sensing, package, and accuracy specs. | Preferred where legacy PWM-compatible ECUs require fixed-period pulse-width modulation output. | Select when system architecture mandates PWM timing compatibility over SPC's master-triggered determinism. |
| TLE49SRS8XUMA1 | SENT interface (SAE J2716-2016) instead of SPC; same stray field robustness and EEPROM features. | Used where higher bandwidth (up to 125 kbps) and multi-sensor daisy-chaining are required. | Choose for next-gen vehicle platforms adopting SENT for centralized sensor networks and enhanced diagnostics. |
Compared with TLE49SRC8XUMA1, the PWM variant offers simpler ECU integration but lacks SPC's precise frame synchronization, while the SENT variant adds protocol overhead and wiring complexity but enables richer diagnostic data exchange.

FAQ
What is the maximum allowable voltage on the I/O pin during SPC communication?
The I/O pin supports up to 19.5 V maximum continuous voltage and 30 V transient peaks (50 µs duration), per AEC-Q100 absolute maximum ratings. This ensures compatibility with 12 V automotive buses and transient suppression circuits without external clamping diodes.
How does the SPC Frameholder mechanism improve real-time control reliability?
The Frameholder hardware synchronizes angle data capture to an external master trigger pulse, guaranteeing that each transmitted value corresponds to a known, deterministic point in the control loop cycle - eliminating timing jitter and preventing stale or interpolated values in safety-critical applications.
Can the EEPROM store custom calibration data beyond zero-angle offset?
Yes - the on-chip EEPROM stores not only user-defined zero angle but also programmable measurement range boundaries, bus capability bits (e.g., 3.3 V pull-up enable), and a 128-word LUT for systematic error correction derived from magnetic circuit characterization.
Is the TLE49SRC8XUMA1 qualified for placement directly on engine control units?
Yes - it is AEC-Q100 Grade 1 qualified (−40°C to +125°C ambient), supports 15,000 hours of operation at max temperature, and withstands 54,000 ignition cycles, making it suitable for under-hood mounting on engine control modules and transmission control units.
