The Infineon Technologies TDA7255V is a highly efficient RF transceiver IC designed for general ISM band applications below 1GHz, specifically operating at 434MHz. This component is optimized for transmit-only functionality, offering a maximum output power of 13dBm. It supports both ASK and FSK modulation schemes and achieves a data rate of up to 100Kbps. With a typical receiving sensitivity of -115dBm and low current consumption in both receive (8.6mA - 9.5mA) and transmit (5mA - 18.3mA) modes, the TDA7255V is suitable for power-constrained designs.
Key features include I2C and SPI serial interfaces for flexible control and configuration. The device operates over a wide temperature range of -40°C to 85°C and is housed in a 40-VFQFN exposed pad package, facilitating surface mounting. This component finds application in various industries including automotive, industrial automation, and consumer electronics where reliable short-range wireless communication is essential.
