NXP Semiconductors PREV601M

Overview

PREV601M from NXP Semiconductors is a compact micro evaluation board built around the PRH601HL multi-chip module, integrating CLRC663 (13.56 MHz contactless transceiver), HTRC110 (125 kHz reader IC), and LPC1227 ARM Cortex-M0 microcontroller. It supports MIFARE Ultralight/Classic/DESFire, ISO/IEC 14443-A/B, ISO/IEC 15693, FeliCa, and NFC peer-to-peer (SNEP client) operation. Designed for rapid firmware prototyping of secure contactless readers.

For engineers reviewing the PREV601M datasheet, PREV601M pinout, PREV601M application, or PREV601M equivalent, this board enables validation of NFC reader stack integration, low-power card detection (LPCD), NDEF message exchange, and hardware abstraction layer (HAL) porting across LPC1227-based designs - with full support for LPCXpresso IDE v4.x and NXP Reader Library (NxpRdLib).

Technical Context

The PREV601M implements a dual-frequency (125 kHz + 13.56 MHz) reader platform using SPI-connected CLRC663 and HTRC110 ICs, managed by the on-board LPC1227 MCU running NxpRdLib's layered architecture (BAL/HAL/PAL/AL). It executes pre-integrated projects for tag polling, MIFARE read/write, and SNEP-based P2P communication with Android devices.

Hardware configuration is controlled via #define PREV601M in hw_config.h, selecting board-specific pin mappings and enabling internal oscillator clocking (no external crystal required). The board relies on external LPC-Link (LPC3154) for JTAG/SWD debug and flash programming, requiring two USB connections for full operation.

FAQ

What is the PREV601M and how does it differ from the PREV601 board?

The PREV601M is a compact micro evaluation board derived from the full-size PREV601 demo board. Both integrate the PRH601HL module (CLRC663 + HTRC110 + LPC1227), but the PREV601M uses the internal RC oscillator instead of an external crystal and omits certain connectors and test points to reduce footprint. Software support is identical, with board-specific configuration activated via #define PREV601M in hw_config.h. PREV601M targets space-constrained prototyping where full PREV601 features are not required.

Which microcontroller and RF ICs are integrated on the PREV601M?

The PREV601M integrates the NXP LPC1227 ARM Cortex-M0 microcontroller (45 MHz, 128 KB Flash), CLRC663 13.56 MHz contactless transceiver (supporting ISO/IEC 14443-A/B, MIFARE, FeliCa, NFC), and HTRC110 125 kHz reader IC (ISO/IEC 18000-2). These are co-packaged in the PRH601HL multi-chip module. The LPC1227 communicates with both RF ICs via dedicated SPI interfaces configured in the NxpRdLib HAL layer.

Does the PREV601M support NFC peer-to-peer (P2P) communication?

Yes, the PREV601M supports NFC peer-to-peer communication as a SNEP client using the NxpRdLib P2P extensions. It implements LLCP and ISO/IEC 18092 protocols over the CLRC663, enabling transmission of hardcoded NDEF messages (e.g., PNG images, URIs, text) to Android 4.0+ devices. The SNEP client project runs on the LPC1227 and requires proper antenna tuning and proximity alignment - no additional hardware beyond the PREV601M and target NFC device is needed.

What development tools and software are required to use the PREV601M?

To develop with the PREV601M, you need the LPCXpresso IDE v4.x (not newer versions), NXP Reader Library (NxpRdLib), and an external LPC-Link debugger (LPC3154-based, e.g., cut from LPCXpresso boards). Projects are imported as ZIP archives into LPCXpresso, compiled for Debug or Release configuration, and flashed via JTAG/SWD. Driver installation for LPC-Link ("USB Device with DFU Capabilities") and PREV601M's virtual COM port is required before debugging.

Can the PREV601M operate standalone without a host PC after programming?

Yes - when built in Release configuration, the PREV601M can run autonomously after power-up without host PC connection. The LPC1227 executes the flashed firmware directly from internal Flash memory. However, initial programming, debugging, and serial console output require the LPC-Link debugger and LPCXpresso IDE. Standalone operation supports all core functions: tag polling, MIFARE read/write, LPCD mode, and SNEP client transmission - provided antenna matching and power supply meet specifications.
