The AT86RF231-ZU from Microchip Technology is a versatile RF-CMOS transceiver designed for IEEE 802.15.4, Zigbee, 6LoWPAN, RF4CE, SP100, WirelessHART, and ISM applications. It boasts an industry-leading link budget of 104 dB with a receiver sensitivity of -101 dBm and programmable output power up to +3 dBm.
This transceiver operates within a supply voltage range of 1.8V to 3.6V and features ultra-low current consumption, making it ideal for power-sensitive applications. It includes an integrated RX/TX switch, a fast-settling PLL for frequency hopping, and a 128-byte FIFO for data buffering. The device supports data rates up to 2 Mbps and utilizes O-QPSK modulation.
Designed for ease of use and low BoM cost, the AT86RF231-ZU requires few external components. It communicates via a fast SPI interface and needs only two microcontroller GPIO lines plus an interrupt pin. The transceiver supports special IEEE 802.15.4 hardware features like FCS computation, clear channel assessment, RSSI measurement, and energy detection. It also includes a MAC hardware accelerator for automated acknowledgements, CSMA-CA, and retransmissions, as well as an AES 128-bit hardware accelerator for enhanced security.
The AT86RF231-ZU is available in a 32-pin low-profile QFN package measuring 5 x 5 x 0.9 mm³. It operates across industrial and extended temperature ranges, from -40°C to +85°C and -40°C to +125°C.
