Product details

Overview

TLE5014C16XUMA1 from Infineon Technologies is a GMR-based automotive angle sensor with SPC (Short PWM Code) interface, delivering 12-bit absolute angle measurement over 360° with ≤1° total error across -40°C to +125°C ambient, ASIL-D compliance per ISO 26262, and integrated EEPROM for zero-angle calibration and 112-bit customer ID storage - deployed in steering angle sensing systems.

For engineers reviewing the TLE5014C16XUMA1 datasheet, TLE5014C16XUMA1 pinout, TLE5014C16XUMA1 application, or TLE5014C16XUMA1 equivalent, key selection criteria include SPC protocol timing compliance, magnetic field range (33–50 mT), functional safety architecture (SPFM >97%), and PG-TDSO-16 package compatibility with automotive PCB layouts.

Technical Context

The TLE5014C16XUMA1 implements Giant Magneto Resistance (GMR) sensing with dual orthogonal bridges (XMR_X/XMR_Y) feeding SD-ADCs, followed by hardware CORDIC computation for real-time angle extraction. Its internal PMU supplies three regulated domains (VRS/VRA/VRD) directly from VDD, enabling robust operation under automotive voltage transients.

Functional safety is enforced via dual ISM blocks (ISM_SAF for safety monitoring, ISM_ALG for signal processing), redundant checksum validation on SPC frames, and continuous self-test of ADC paths, temperature sensor, and EEPROM integrity - all supporting ASIL-D decomposition per ISO 26262 Part 5.

Key Specifications

Parameter	Value and Actual Design Meaning
Angle Resolution	12-bit digital output (0–4095 steps), enabling 0.0879° quantization step for high-precision rotor position tracking.
Angle Accuracy	≤ ±1° total error over full temperature (-40°C to +125°C) and magnetic field (33–50 mT) range - validated for lifetime steering column reliability.
Interface Protocol	SPC (Short PWM Code) compliant with Infineon's proprietary bus-mode timing, supporting multi-sensor daisy-chaining via IF1/IF2 address pins.
Functional Safety	ASIL-D development process per ISO 26262; SPFM >97% achieved via hardware redundancy, lockstep monitoring, and fault injection test coverage.
Operating Voltage	4.5 V to 5.5 V supply range - compatible with automotive 5 V rail; reverse polarity protection up to -16 V prevents damage during battery jump-start events.
EEPROM Capacity	256-bit EEPROM (128-bit config + 112-bit customer ID), programmable via SICI interface for production-line zero-angle offset and traceability.
ESD Robustness	4 kV HBM on VDD and output pins - ensures resilience against assembly handling and in-vehicle electrostatic discharge events.

Pinout & Package

PG-TDSO-16 (Plastic Thin Dual Small Outline) package: 16-pin, 150 mil body width, 1.27 mm pitch, exposed thermal pad, RoHS/halogen-free, qualified per AEC-Q100 Grade 1.

Pin/Terminal	Circuit Role	Design Meaning
VDD	Supply Input	Primary 4.5–5.5 V power input; internally regulates VRS/VRA/VRD rails for analog/digital/GMR subsystems.
GND	Ground Reference	Analog/digital common ground; low-inductance connection required to minimize noise coupling into GMR bridges.
OUT	SPC Output Driver	Open-drain NMOS output driving SPC pulse train; supports 10 mA sink current and 100 ns rise/fall times at 5 V load.
IF1 / IF2	Interface Address Inputs	Binary-coded pins selecting SPC bus address (0–3); pulled high/low at power-up to configure device ID in multi-sensor networks.
TEMP	Temperature Sensor Output	Analog voltage proportional to die temperature (10 mV/K), used for on-chip thermal compensation of angle error.
NC	No Connect	Pins 5, 6, 7, 12, 13, 14, 15, 16 are unconnected - must be left floating or tied to GND per layout guidelines to avoid parasitic coupling.

Key Features

Feature	Design Value
32-point LUT correction	Programmable look-up table compensates systematic angular errors from magnetic circuit asymmetry or mechanical misalignment - applied pre-CORDIC to raw ADC data.
SPC master-trigger synchronization	Supports external trigger pulses (min. 1 µs high time) to align multiple TLE5014C16XUMA1 devices for synchronized sampling in multi-axis steering systems.
Integrated temperature sensor	On-die thermal diode enables real-time angle error correction across -40°C to +125°C without external components.
High-voltage tolerance	Withstands 16 V reverse polarity and transient surges up to 40 V - eliminates need for external TVS diodes in 12 V automotive systems.
Customer ID programming	112-bit unique identifier stored in EEPROM allows OEM-level traceability and anti-counterfeit verification during EOL testing.

Applications

Steering Angle Sensing

Electric Power Steering (EPS)

Use Scenario: Real-time measurement of steering wheel rotation angle for vehicle dynamics control and lane-keeping assist.

IC Role / Device Role / Timing Role: Primary angle transducer providing 12-bit absolute position at ≥100 Hz update rate via SPC interface to EPS ECU.

Use Value: ≤1° lifetime accuracy ensures precise torque overlay and steering feel calibration across full vehicle lifecycle and temperature extremes.

Use Scenario: Closed-loop feedback for motor current control in column-assist or rack-assist EPS architectures.

IC Role / Device Role / Timing Role: High-reliability angle source with ASIL-D safety mechanisms enabling functional safety compliance for EPS ASIL-C decomposition.

Use Value: Integrated safety monitors (SPFM >97%) reduce external diagnostic overhead and simplify ISO 26262 FMEDA reporting.

Active Suspension Control

Four-Wheel Steering (4WS)

Use Scenario: Front axle angle input for adaptive damping and roll stabilization algorithms in premium chassis systems.

IC Role / Device Role / Timing Role: Secondary angle sensor fused with IMU data; SPC output synchronized to chassis controller clock via external trigger.

Use Value: 32-point LUT correction compensates for mounting tolerances in suspension knuckle assemblies, eliminating manual calibration.

Use Scenario: Independent rear axle angle measurement enabling coordinated front/rear steering geometry for low-speed maneuverability.

IC Role / Device Role / Timing Role: Redundant angle node in distributed 4WS ECU architecture; communicates via daisy-chained SPC bus using IF1/IF2 addressing.

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
AMS AS5055A-BQFT	14-bit resolution, SPI interface only; no SPC or SENT; lacks ASIL-D certification and EEPROM-based zero-angle storage.	Targeted at non-safety-critical industrial encoders; requires external microcontroller for SPI polling and temperature compensation.	Select when higher resolution is prioritized over functional safety compliance and automotive bus integration.
NXP MR3301	SENT-only interface; 12-bit output; ASIL-B rated; no EEPROM for customer ID; 3.3 V supply only.	Designed for throttle/pedal position sensing; not qualified for continuous 125°C ambient or steering column vibration profiles.	Select for cost-sensitive SENT-only systems where ASIL-D is not mandated and thermal derating is acceptable.

Compared with AMS AS5055A-BQFT and NXP MR3301, the TLE5014C16XUMA1 uniquely combines ASIL-D compliance, SPC bus capability, on-chip LUT correction, and 112-bit programmable ID - making it the only drop-in solution for OEM steering angle modules requiring full ISO 26262 traceability and production-line configurability.

FAQ

What is the SPC interface timing requirement for TLE5014C16XUMA1?

The SPC interface uses a master-triggered protocol with defined unit times: t_LOW = 1.5 µs ±10%, t_HIGH = 1.5 µs ±10%, and blanking time of 2.5 µs after trigger assertion. Frame structure includes status nibble, 12-bit angle, and 4-bit checksum - all verified per Infineon Application Note AN478.

How is the zero-angle offset programmed and retained?

Zero-angle offset is stored in the 256-bit EEPROM via the SICI (Serial Interface for Configuration and Initialization) using a dedicated programming sequence. Data persists over 100k write cycles and 15-year retention at 125°C ambient, validated per Table 3-13 in the datasheet.

Does TLE5014C16XUMA1 support daisy-chaining with other sensors?

Yes - the SPC bus mode enables up to four TLE5014C16XUMA1 devices on a single output line using IF1/IF2 address pins (00, 01, 10, 11). Each device responds only to its assigned address, with automatic blanking to prevent frame collisions during simultaneous transmission.

What failure modes are covered by the internal safety mechanisms?

The TLE5014C16XUMA1 monitors GMR bridge imbalance, ADC saturation, temperature sensor open/short, EEPROM CRC errors, and SPC frame checksum failures. Detected faults assert a dedicated safety flag and force OUT pin into safe state (high-impedance or fixed pulse pattern) per ISO 26262 requirements.
