A7129 is a low-IF CMOS FSK/GFSK transceiver for 315/433/470/868/915 MHz ISM bands, ideal for battery-powered wireless applications (e.g., AMR, Wireless M-Bus). It features ultra-low power (3.8 mA RX, 24 mA TX), high-efficiency PA (up to 12 dBm), -108 dBm RX sensitivity, and a baseband modem supporting 2–250 kbps.
Control is via SPI and GPIOs, supporting sleep/idle/PLL/TX/RX modes. Packet handling includes direct and FIFO modes with CRC, FEC, Manchester coding, and data whitening. Additional features: on-chip regulator, RSSI, thermal sensor, low battery detection, auto-calibration, auto-ACK/resend, and Wake-on-RX. All in a 4×4 mm QFN 24-pin package.
