STMicroelectronics ST25R3918-AQWT RF Transceiver RFID Reader 27.12MHz, 5.5V

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
