2. General description

PN7120, the best plug'n play full NFC solution - easy integration into any OS environment,

with integrated firmware and NCI interface designed for contactless communication at

13.56 MHz.

It is the ideal solution for rapidly integrating NFC technology in any application, especially

those running OS environment like Linux and Android, reducing Bill of Material (BOM)

size and cost, thanks to:

• full NFC forum compliancy (see Ref. 11) with small form factor antenna

• embedded NFC firmware providing all NFC protocols as pre-integrated feature

• direct connection to the main host or microcontroller, by I2C-bus physical and NCI

protocol

• ultra-low power consumption in polling loop mode

• Highly efficient integrated power management unit (PMU) allowing direct supply from

a battery

PN7120 embeds a new generation RF contactless front-end supporting various

transmission modes according to NFCIP-1 and NFCIP-2, ISO/IEC14443, ISO/IEC 15693,

ISO/IEC 18000-3, MIFARE and FeliCa specifications. It embeds an ARM Cortex-M0

microcontroller core loaded with the integrated firmware supporting the NCI 1.0 host

communication.

The contactless front-end design brings a major performance step-up with on one hand a

higher sensitivity and on the other hand the capability to work in active load modulation

communication enabling the support of small antenna form factor

Supported transmission modes are listed in Figure 1. For contactless card functionality,

the PN7120 can act autonomously if previously configured by the host in such a manner.

PN7120 integrated firmware provides an easy integration and validation cycle as all the

NFC real-time constraints, protocols and device discovery (polling loop) are being taken

care internally. In few NCI commands, host SW can configure the PN7120 to notify for

card or peer detection and start communicating with them.
