Product details
Overview
MLX90132SLQ-AEA-000-RE from Melexis is an NFC reader IC supporting ISO/IEC 14443A/B and ISO/IEC 18092 (NFCIP-1) protocols, operating at 13.56 MHz with integrated analog front-end, digital signal processor, and host interface (SPI/I²C). It delivers 1.7–3.6 V supply operation, -40°C to +105°C ambient range, and supports contactless smart card and tag reading in automotive passive keyless entry systems.
For engineers reviewing the MLX90132SLQ-AEA-000-RE datasheet, pinout, applications, or equivalent options, this device serves as a certified NFC transceiver for secure key fob authentication, vehicle access handshaking, and proximity-based challenge-response protocols in Entry & Go architectures.
Technical Context
The MLX90132SLQ-AEA-000-RE implements a fully integrated NFC reader architecture with on-chip RF front-end, demodulator, decoder, CRC engine, and protocol state machine compliant with ISO/IEC 14443A/B Layers 1–4 and NFCIP-1. It supports both active and passive communication modes and includes built-in collision avoidance for multi-tag environments.
Host control is implemented via configurable SPI (up to 10 MHz) or I²C (up to 400 kHz), with dedicated interrupt signaling and power management features including low-power standby mode (<10 µA) and wake-on-field detection. The device requires no external crystal-internal oscillator enables full system timing autonomy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz carrier-enables interoperability with standard NFC tags, MIFARE, and ISO-compliant smart cards. |
| Supply Voltage Range | 1.7 V to 3.6 V-supports direct connection to automotive body controller LDOs or battery-backed backup rails. |
| Temperature Range | -40°C to +105°C-qualified for under-hood and door module mounting in automotive passive keyless systems. |
| Interface Options | SPI (10 MHz max) and I²C (400 kHz fast-mode)-allows flexible host MCU integration without additional level-shifting circuitry. |
| RF Output Power | Programmable up to +10 dBm-adjustable field strength meets ETSI EN 300 330 and FCC Part 15 requirements for short-range RFID/NFC. |
| Power Consumption (Standby) | <10 µA-enables always-on field sensing in ultra-low-power vehicle access monitoring states. |
Pinout & Package
MLX90132SLQ-AEA-000-RE is housed in a 32-pin QFN package (5 mm × 5 mm, 0.5 mm pitch) with wettable flank terminations for automated optical inspection (AOI) compatibility and robust solder joint reliability in automotive reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core supply input | Connects to regulated 1.8 V or 3.3 V rail; internal LDOs power analog and digital blocks independently. |

Both interfaces include dedicated interrupt signaling and register-level configuration access. MLX90132SLQ-AEA-000-RE does not support UART or USB natively-external bridge ICs would be required for those protocols.
Is the MLX90132SLQ-AEA-000-RE qualified for automotive use?
Yes, the MLX90132SLQ-AEA-000-RE is AEC-Q100 Grade 2 qualified, tested for operation from -40°C to +105°C, and validated for mechanical shock, thermal cycling, and ESD (±8 kV HBM). It meets automotive EMC requirements per CISPR 25 Class 5 and is designed for integration into door modules, center consoles, and steering column assemblies where MLX90132SLQ-AEA-000-RE serves as the certified NFC reader node.
Does the MLX90132SLQ-AEA-000-RE require an external crystal or oscillator?
No, the MLX90132SLQ-AEA-000-RE integrates a precision internal oscillator that eliminates the need for an external crystal or resonator. This reduces bill-of-materials count and PCB area while ensuring timing stability across temperature and voltage ranges. The internal oscillator directly drives the 13.56 MHz RF carrier and digital timing blocks-no external timing source is required for MLX90132SLQ-AEA-000-RE operation.
Which NFC and RFID standards does the MLX90132SLQ-AEA-000-RE support?
The MLX90132SLQ-AEA-000-RE supports ISO/IEC 14443A and ISO/IEC 14443B for contactless smart cards, plus ISO/IEC 18092 (NFCIP-1) for peer-to-peer and reader/writer modes. It does not support ISO/IEC 15693 (VICC) or FeliCa. MLX90132SLQ-AEA-000-RE is certified for interoperability with MIFARE Classic, DESFire EV1/EV2, and NFC Forum Type 2/4 tags used in automotive key fobs.
Can the MLX90132SLQ-AEA-000-RE operate in low-power modes for battery-backed systems?
Yes, the MLX90132SLQ-AEA-000-RE features a dedicated low-power standby mode consuming less than 10 µA, with wake-on-field detection enabling autonomous activation upon RF field presence. This allows integration into energy-constrained subsystems such as door handle modules powered by backup capacitors or supercapacitors-MLX90132SLQ-AEA-000-RE maintains readiness without draining primary vehicle battery reserves.
