The ATA5577 (T5577 for short) chip from Microchip (formerly Atmel) is a very poular Low Frequency (125KHz) card. It is compatible with Microchip's T5557/ATA5567 and a replacement for the e5551/T5551 in many common operations. T5577 has a frequency of 125KHz but its strength comes from the fact it is a re-writable card so it can flexibly imitate UID/card numbering of other 125KHz formats, making them easy to configure with compatible 125KHz readers.

The technology is popular for physical access control to business premises and in hotels or applications in general where the chip number is read for identification purposes.
