The STMicroelectronics ST25R3918 is a multipurpose NFC transceiver supporting NFC reader, passive peer to peer functionality and NFC card emulation mode. This IC is optimized for IOT and other consumer or industrial applications where excellent analog performance is required. The ST25R3918 is also optimized to achieve good read ranges with low output power, even under noisy and harsh environments, using noise reduction receiver technology.

Dynamic power output (DPO) controls the
field strength to stay within given limits
Active wave shaping (AWS) reduces overand
under-shoots
Noise suppression receiver (NSR) allows
reception in noisy environment
Automatic gain control and squelch feature
to maximize SNR
Low power inductive card detection
Low power NFC passive target modes
Adjustable ASK modulation depth, from 5
to 40%
Integrated regulators to boost system
PSRR
