Key Features
- Full ISO 14443 Type-B protocol implementation at 13.56 MHz enables interoperability with contactless smart cards and proximity cards in payment and access control systems
- ASK modulation transceiver with 4.5 V to 5.5 V supply draws under 20 mA, allowing integration into low-power portable and embedded reader designs
- 16-pin SO-16 package simplifies PCB layout for contactless coupler front-ends with minimal external RF interface components
Applications
The CRX14-MQP/1GE is designed for contactless smart card reader terminals complying with ISO 14443 Type-B, including transit ticketing systems, access control panels, and NFC-enabled point-of-sale readers. It handles the 13.56 MHz RF front-end coupling and protocol framing, offloading these tasks from the host microcontroller. The chip suits embedded reader modules in vending machines, parking systems, and government ID document verification equipment.

Frequently Asked Questions
What RF frequency and protocol standards does the CRX14-MQP/1GE implement for contactless card communication?
The CRX14-MQP/1GE operates at 13.56 MHz and fully implements the ISO 14443 Type-B standard, covering the ASK modulation layer defined in ISO 14443-2 and the initialization and anticollision protocol in ISO 14443-3. This makes it interoperable with ISO 14443-B contactless smart cards used in national ID documents, transit fare cards, and banking contactless payment cards that comply with EMVCo specifications.
Which embedded reader application scenarios benefit from deploying the CRX14-MQP/1GE contactless coupler chip?
Transit gate readers, access control door units, parking ticket machines, and point-of-sale terminals that need to read ISO 14443 Type-B proximity cards within a range of up to 10 cm benefit from the CRX14-MQP/1GE. The chip's 4.5 V to 5.5 V supply range is compatible with standard 5 V embedded systems, while its maximum 20 mA current draw allows operation from regulated USB or wall-adapter supplies in compact, fixed-mount reader enclosures.
What supply voltage and current does the CRX14-MQP/1GE require, and how does the 16-pin SO-16 package affect board layout?
The CRX14-MQP/1GE operates from a 4.5 V to 5.5 V supply and draws up to 20 mA during active RF transmission. The 16-pin SO-16 package with 1.27 mm pin pitch fits on a compact PCB and requires a relatively small antenna matching network of a few nH inductors and pF capacitors placed close to the RF pins. The small footprint allows integration of the contactless coupler into single-board reader designs for access control and ticketing without a dedicated daughter card.
