Microchip Technology, Inc. RF Transceiver ICs - ATA8515-GHQW ATA8515-GHQW

The ATA8515-GHQW is a low-power UHF ASK/FSK RF transceiver IC designed for operation in ISM frequency bands ranging from 310MHz to 956MHz. It features an integrated AVR microcontroller core with 1Kbyte SRAM and a 24Kbyte RF library in firmware, but does not include user memory. The device supports programmable output power from -12dBm to +14.5dBm and has low current consumption, with 9.8mA in RX mode and 9.4mA in TX mode at 6dBm output. The transceiver offers high sensitivity levels, with FSK sensitivity at 433.92MHz reaching -114dBm at 5Kbit/s and ASK sensitivity at the same frequency reaching -125dBm at 0.5Kbit/s. It supports a wide range of data rates from 0.5Kbit/s to 80Kbit/s and features a programmable Rx-IF bandwidth from 25kHz to 366kHz. The device is housed in a compact 5mm x 5mm QFN32 package and operates within a supply voltage range of 1.9V to 3.6V, with a temperature range of -40¬8C to +85¬8C. Applications include remote control systems, home automation, wireless sensor networks, and battery-operated devices. The ATA8515-GHQW is suitable for projects requiring robust wireless communication with minimal external components.
