1. Introduction
1.1. General Description
The NFC module is a highly integrated transceiver module for contactless reader/writer
communication at 13.56 MHz. The main chip of this NFC module is NXP NQ310.
NQ310 is an NFC controller designed for integration in mobile devices and devices compliant
with NFC standards (NFC Forum, NCI, EMVCo, ETSI/SCP).
NQ310 is designed based on learnings from previous NXP NFC device generation to ease the
integration of NFC technology in mobile devices by providing:
• An optimized architecture for low-power consumption in different modes (Standby,
low-power polling loop)
• A highly efficient integrated power management unit allowing direct supply from an
extended battery supply range (2.8 V to 5.5 V). Moreover, this power management
provides full flexibility to support the different configurations in the mobile devices
(screen ON, screen OFF, phone OFF)
•2 SWP pads for UICC connections with dedicated power supply lines
NQ310 embeds a new generation RF contactless front-end supporting various transmission
modes according to NFCIP-1 and NFCIP-2, ISO/IEC14443, ISO/IEC 15693, MIFARE and FeliCa
specifications. This new 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. It also
allows to provide a higher output power by supplying the transmitter output stage from 2.7
V to 5.25 V.
• Enhanced Dynamic LMA (DLMA) to optimize and to enhance load modulation
amplitude depending on external field strength. It allows higher range communication
distance in card mode.
• Independent LMA phase adjustment by step of 5° for type A, B and F
• Dynamic Power control which allows to make use of the maximum power in reader
mode without exceeding the maximum power allowed by the standard in 0 distance.
• Improved card mode receiver sensitivity down to 20 mV(p-p)
