Product details
Overview
SLRC61003HNY from NXP Semiconductors is a high-performance, low-cost RFID frontend IC supporting ISO/IEC 15693, ICODE EPC UID, and ISO/IEC 18000-3 Mode 3/EPC Class-1 HF protocols. It operates from 2.5 V to 5.5 V, integrates a 512-byte FIFO buffer, and features dedicated SAM interface via separate I²C for secure key storage and cryptographic acceleration - deployed in industrial access control readers and gaming authentication terminals.
For engineers reviewing the SLRC61003HNY datasheet, SLRC61003HNY pinout, SLRC61003HNY application, or SLRC61003HNY equivalent, this page delivers verified protocol support (ISO/IEC 15693 + EPC UID + 18000-3 Mode 3), confirmed HVQFN32 package with wettable flanks, validated low-power card detection (LPCD) register configuration (LPCD_OPTIONS), SPI/I²C/UART host interface timing specs, and real-world interrupt behavior (TxIRQ, RxIRQ, LPCDIRQ).
Technical Context
The SLRC61003HNY implements a dual-transmitter analog front-end (TX1/TX2) with RXP/RXN differential receiver inputs and VMID reference, enabling robust 13.56 MHz RF field generation and demodulation. Its integrated PLL derives system clock from a 27.12 MHz quartz crystal, eliminating external clock sources.
It embeds five programmable timers - four configurable to 13.56 MHz or 212 kHz, plus Timer4 driven by an internal LFO for wake-up and low-power card detection - and supports flexible host interface auto-detection via IFSEL0/IFSEL1 pins, with dedicated IRQ output for event-driven firmware handling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RFID frontend applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLRC61002HN | Wider supply range (3.0–5.5 V); lacks LPCD_OPTIONS register and enhanced Load Protocol settings. | Less suitable for battery-powered or small-antenna designs requiring fine-grained LPCD tuning. | Select SLRC61002HN only if legacy 3.3 V/5 V fixed-rail supply and simplified LPCD are sufficient. |
| CLRC66302HN | Supports ISO/IEC 14443 A/B and FeliCa in addition to ISO/IEC 15693; higher supply current (up to 350 mA). | Better suited for dual-interface (contactless smartcard + vicinity) readers, not optimized for pure HF RFID inventory. | Choose CLRC66302HN when multi-standard compliance (e.g., payment + asset tracking) is mandatory. |
Compared with SLRC61002HN, SLRC61003HNY offers superior low-power card detection configurability and small-antenna optimization; versus CLRC66302HN, it delivers lower power consumption and streamlined firmware for ISO/IEC 15693–focused applications.

FAQ
What RF protocols does the SLRC61003HNY support?
The SLRC61003HNY supports ISO/IEC 15693 (vicinity), ICODE EPC UID/OTP, and ISO/IEC 18000-3 Mode 3/EPC Class-1 HF protocols. It does not support ISO/IEC 14443 or FeliCa. All three protocols are implemented in hardware with independent modulation/demodulation paths, enabling simultaneous protocol readiness without firmware reconfiguration. The SLRC61003HNY datasheet confirms full compliance with each standard's physical layer requirements.
How does the SLRC61003HNY differ from the SLRC61002HN variant?
The SLRC61003HNY operates from 2.5 V to 5.5 V (vs. 3.0 V–5.5 V for SLRC61002HN) and introduces the LPCD_OPTIONS register for advanced low-power card detection tuning. It also adds new Load Protocol settings optimized for smaller antennas. These enhancements make SLRC61003HNY the recommended version for new designs, especially battery-powered or space-constrained readers where SLRC61003HNY's extended voltage range and configurability provide tangible design advantages.
What host interfaces are supported by the SLRC61003HNY and how are they selected?
The SLRC61003HNY supports SPI (≤10 Mbit/s), I²C (≤1000 kBd Fast mode plus), and UART (≤1228.8 kBd). Interface selection is hardware-configured at power-up using IFSEL0 and IFSEL1 pins - no firmware initialization is needed. Pin states define the mode (e.g., IFSEL0 = VSS, IFSEL1 = PAD_VDD selects SPI), and the SLRC61003HNY automatically initializes the corresponding peripheral logic. This eliminates boot-time interface negotiation and simplifies host driver development.
Does the SLRC61003HNY include a dedicated interface for secure elements?
Yes, the SLRC61003HNY includes a dedicated I²C-bus interface specifically for connecting a Secure Access Module (SAM). This SAM interface operates independently from the main host I²C port and is designed to offload cryptographic operations (e.g., AES, DES) and securely store keys. The SLRC61003HNY datasheet specifies that the SAM interface uses SCL/SAM_SDA pins and supports secure key provisioning - enhancing system-level security without burdening the host MCU.
What is the purpose of the IRQ pin on the SLRC61003HNY and which events trigger it?
The IRQ pin on the SLRC61003HNY is an active-low interrupt output signaling critical RF and system events. It asserts on TxIRQ (transmission complete), RxIRQ (reception complete), LPCDIRQ (card detected in low-power mode), and ErrIRQ (communication error). Each source is individually maskable via IRQ0En/IRQ1En registers. This enables event-driven firmware - eliminating polling loops and reducing host CPU load. The SLRC61003HNY datasheet defines IRQ behavior in Section 8.1 and Table 5, confirming its use in real-time reader applications.
