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
