NXP's PN7360AUHN/C300Y family is based on the first single-chip, dual-interface reader IC. Equipped with a low-power ARM® Cortex®-M0 microcontroller core with USB, the family supports contact and contactless interfaces with full NFC functionality. Low-power operation, extensive memory resources, a complete set of host and peripheral interfaces, and reader libraries compliant with different standards combined to enhance performance while simplifying final certification and delivery. The family includes the PN7462, which has an optional contact interface and 160 KB of Flash, the PN7362 with 160 KB of Flash, and the PN7360 with 80 KB of Flash. These state-of-the-art devices are single-chip solutions for contact, contactless, and NFC operation, and can be loaded with fully custom applications. Optimized antenna operation and low-power modes enable best-in-class performance.
