Product details
Overview
SLRC61003HNE from NXP Semiconductors is a high-performance, multi-protocol NFC frontend IC supporting ISO/IEC 15693, ICODE EPC UID, and ISO/IEC 18000-3 Mode 3/EPC Class-1 HF read/write modes. It operates from 2.5 V to 5.5 V, integrates a 512-byte FIFO buffer, and features low-power card detection (LPCD) with configurable LPCD_OPTIONS register for optimized antenna compatibility. It serves as the RF interface controller in industrial access readers and secure gaming terminals.
For engineers reviewing the SLRC61003HNE datasheet, SLRC61003HNE pinout, SLRC61003HNE application, or SLRC61003HNE equivalent, key selection considerations include its 2.5–5.5 V supply range, dedicated SAM I²C interface, 10 Mbit/s SPI host interface, flexible LPCD configuration, and HVQFN32 thermal-enhanced package with wettable flanks.
Technical Context
The SLRC61003HNE implements a fully integrated analog front-end for 13.56 MHz RFID systems, including dual TX outputs (TX1/TX2), differential RX inputs (RXP/RXN), and internal VMID reference generation. Its digital core includes five timers (four programmable + one LFO-based wake-up timer), interrupt controller with IRQ pin, and register-banked state machines for protocol handling.
Host communication is dynamically selected at power-up via IFSEL0/IFSEL1 pins, enabling SPI (up to 10 Mbit/s), I²C (Fast mode plus, up to 1000 kBd), or UART (RS232-level, up to 1228.8 kBd). A separate I²C bus supports secure access module (SAM) integration for cryptographic acceleration and key storage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC frontend applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLRC61002HN | 2.5–5.5 V supply same, but lacks LPCD_OPTIONS register and optimized load protocol settings for small antennas | Less suitable for compact, battery-powered readers requiring fine-grained card detection tuning | Select SLRC61003HNE for new designs needing enhanced LPCD flexibility and smaller antenna compatibility |
| PN5180A0HN/C1 | Supports NFC Forum Type A/B/F and ISO/IEC 14443, but not ISO/IEC 15693 or EPC Class-1 HF; higher power consumption (≥5 mA active) | Targeted at smartphone-style NFC readers, not industrial ISO/IEC 15693 infrastructure | Choose SLRC61003HNE when ISO/IEC 15693 or EPC UID compliance is mandatory |
Compared with SLRC61002HN, SLRC61003HNE adds critical LPCD configuration registers and antenna-load optimizations; compared with PN5180A0HN/C1, it delivers native ISO/IEC 15693/EPC Class-1 HF support with lower active current and industrial temperature range - making it the only drop-in solution for legacy ICODE infrastructure upgrades.

FAQ
What protocols does the SLRC61003HNE support?
The SLRC61003HNE supports three distinct contactless protocols: ISO/IEC 15693 (including ICODE variants), ICODE EPC UID/EPC OTP, and ISO/IEC 18000-3 Mode 3/EPC Class-1 HF. It does not support ISO/IEC 14443 (Type A/B) or NFC Forum protocols. Each mode is implemented in hardware with dedicated modulation and decoding logic, enabling concurrent protocol readiness without host firmware translation.
How does the SLRC61003HNE handle low-power card detection (LPCD)?
The SLRC61003HNE implements hardware-accelerated LPCD using its internal LFO and Timer4, with sensitivity and timing parameters configured via the LPCD_OPTIONS register. This allows precise tuning for small antennas and variable tag distances - a feature absent in SLRC61002HN. In LPCD mode, current drops to ≤40 nA, and detection events trigger the IRQ pin to wake the host MCU.
What host interfaces are supported by the SLRC61003HNE, and how are they selected?
The SLRC61003HNE supports SPI (up to 10 Mbit/s), I²C (Fast mode plus, up to 1000 kBd), and UART (RS232-level, up to 1228.8 kBd). Interface selection occurs automatically at power-up based on voltage levels applied to IFSEL0 and IFSEL1 pins - no firmware configuration is required. Pin states are latched during the cold reset phase and remain fixed until next power cycle.
Does the SLRC61003HNE require external components for antenna connection?
The SLRC61003HNE minimizes external components for antenna interfacing: only a matching network (typically two capacitors and one inductor) is needed between TX1/TX2 outputs and the antenna. Its integrated PLL eliminates the need for an external clock source, and internal voltage regulators reduce external decoupling requirements. However, DVDD, AVDD, PVDD, and TVDD each require dedicated 100 nF ceramic bypass capacitors per datasheet layout guidelines.
What is the purpose of the dedicated SAM I²C interface on the SLRC61003HNE?
The dedicated SAM I²C interface (separate SCL/SDA pins) on the SLRC61003HNE provides a physically isolated communication path to a secure access module - such as NXP's SE050 - enabling cryptographic key storage, AES/SHA acceleration, and secure UID verification without exposing keys or operations to the main host interface. This separation meets Common Criteria EAL5+ requirements for tamper-resistant authentication systems.
