Product details
Overview
TLE5014SP16E0002XUMA1 from Infineon is a GMR-based automotive angle sensor delivering 360° absolute angular position with 15-bit resolution (32,768 steps), ±1° total angle error over lifetime and temperature (−40°C to +125°C), and ASIL-D functional safety compliance per ISO 26262. It integrates on-chip EEPROM for zero-angle calibration and customer ID storage, and uses a high-speed SSC interface up to 8 MHz for real-time motor control feedback in electric power steering (EPS) systems.
For engineers reviewing the TLE5014SP16E0002XUMA1 datasheet, TLE5014SP16E0002XUMA1 pinout, TLE5014SP16E0002XUMA1 application, or TLE5014SP16E0002XUMA1 equivalent, this page provides verified technical context, validated pin functions, confirmed safety architecture (SPFM > 97%), calibrated angle performance data, and automotive-grade supply chain availability - all aligned to AEC-Q100 Grade 1 and iGMR sensing requirements.
Technical Context
The TLE5014SP16E0002XUMA1 implements dual-path digital signal processing: ISM_ALG performs primary angle calculation using hardware CORDIC on raw GMR_X/GMR_Y signals, while ISM_SAF executes independent plausibility checks via software CORDIC and cross-compares results via the Angle Compare block. Its internal PLL clock drives synchronized sigma-delta ADCs for GMR bridge and temperature sensing.
It features integrated voltage regulation (VRS/VRA/VRD), a 32-point LUT for systematic magnetic circuit error correction, and configurable SSC communication with CRC-8 and safety word validation. The device enters programming mode automatically at power-up for EEPROM configuration via the same SSC interface used for runtime data reads.

Pinout & Package
Package: PG-TDSO-16 (Thermally enhanced thin dual small-outline package, 16-pin, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IF1) | Bi-directional DATA line (MOSI/MISO) | SSC serial data I/O; requires external pull-up; driver disabled in HIGH state to reduce EMI. |
| 2 (IF2) | Input SCK (SSC clock) | Master-generated clock up to 8 MHz; synchronous edge-triggered sampling of IF1 and IF3. |
| 3 (IF3) | Input CSQ (chip select) | Active-low enable for SSC transaction; must be held LOW during full frame transfer (command + safety + CRC). |
| 4 (VDD) | Supply input | 2.7–5.5 V nominal; internal regulators (VRS/VRA/VRD) derive analog/digital/GMR bias rails; 100 nF decoupling required. |

| 6 (IFA) | Ground tie | Must be connected directly to GND to stabilize internal GMR bridge reference potential. |
| 7 (IFB) | Supply tie | Must be pulled up to VDD via resistor (typ. 2.2 kΩ) to enable internal safety monitoring circuitry. |
| 8 (IFC) | No-connect | Internally unused; must remain open (no external connection or pull-up/down). |
| 9–16 | No-connect | All pins unconnected internally; no routing or termination required. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar GMR-based angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE5012BE1000XUMA1 | 12-bit resolution (4096 steps), ±1.5° error, no EEPROM, lower SSC speed (4 MHz), same PG-TDSO-16 package. | Lacks ASIL-D certification and customer ID storage; suitable for non-safety-critical HVAC damper control. | Select when cost sensitivity outweighs resolution and safety requirements; not drop-in for ASIL-D systems. |
| MLX90412GOA-ABA-000-TU | Tri-axis Hall-based, 14-bit output, ±1.2° error, SPI interface, SOIC-8 package, no functional safety certification. | Lower magnetic immunity (max 100 mT), no internal LUT or dual CORDIC; limited to cabin-level actuators. | Choose only for space-constrained non-automotive applications where GMR-level accuracy and robustness are unnecessary. |
Compared with TLE5014SP16E0002XUMA1, the TLE5012BE1000XUMA1 sacrifices resolution and safety for cost reduction, while the MLX90412GOA-ABA-000-TU trades GMR stability and ASIL-D compliance for smaller footprint and simpler interface - neither matches the combined 15-bit precision, ±1° accuracy, and certified functional safety of the TLE5014SP16E0002XUMA1 in critical drivetrain roles.

FAQ
What is the maximum allowable magnetic field strength for continuous operation?
The TLE5014SP16E0002XUMA1 supports continuous exposure to magnetic fields up to 150 mT at 25°C ambient, with short-term tolerance of 200 mT for ≤5 minutes. Exceeding these limits risks permanent sensor saturation or irreversible GMR element degradation. Magnetic circuit design must maintain field homogeneity within ±5% across the sensitive area to preserve ±1° accuracy.
How is functional safety implemented in the TLE5014SP16E0002XUMA1?
Functional safety is achieved through hardware and algorithmic redundancy: dual independent CORDIC engines (ISM_ALG and ISM_SAF), cross-comparison via Angle Compare logic, CRC-8 and safety word validation on every SSC frame, and internal monitoring of voltage regulators, clock, and EEPROM integrity. SPFM > 97% is verified per ISO 26262 Part 5 Annex D.
Can the EEPROM be reprogrammed in-system after initial calibration?
Yes - the 112-bit customer EEPROM and configuration registers are accessible via the SSC interface during normal operation or dedicated programming mode initiated at power-up. Reprogramming requires valid safety word and CRC-8; write cycles are limited to 100,000 endurance. No external high-voltage programming signal is needed.
What is the purpose of the IFA, IFB, and IFC pins?
IFA must be tied to GND to stabilize the GMR bridge reference; IFB must be pulled up to VDD (typically 2.2 kΩ) to activate internal safety monitors; IFC is a no-connect pin and must remain open. Incorrect handling of IFA or IFB disables critical safety functions and invalidates ASIL-D compliance - these pins are not optional configuration points.
