IM283: Low-voltage reader IC for 100-150kHz tags
Download full datasheet

Product Description ____________________

IM283 is a fully-integrated 125 kHz RFID reader circuit. It is specially designed for being a space and cost efficient kernel IC of an RFID reading and writing base station. It covers the digital real time functions and the analogue signal processing necessary to access most of the 125kHz and 134.2kHz transponders available on the market. IM283 is accessible by a standard micro - controller as an intelligent front - end peripheral device. A unique mutual tuning capability (RTA™) allows dynamic adaptation to every transponder read, particularly in poor reading conditions. IM283 is versatile enough to work in most low-power (short distance) and high power (longer distance) applications. FL283 is fully compatible with latest version of SW016 reader IC.
