How the T5577 / ATA5577 works
The T5577 / ATA5577 is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. The T5577 / ATA5577 is genuine Atmel silicon — data structure Configurable ASK/FSK/PSK/NRZ/BiPhase; emulates EM, HID, Indala, AWID, ioProx, Keri, Pyramid, etc; across up to 7 data blocks + config block — the same chip platform the major lock, transit, hotel and payment systems specify.
We stock it as an encodable blank, supplied unprogrammed or pre-encoded to your specification, so your access-control system, card bureau or application writes it with your own data and keys — exactly as you would chips ordered through the Atmel distribution channel, at a fraction of the price. There is nothing aftermarket about the chip itself; what we add is sourcing, encoding and bulk availability.
Whether you need a handful of spares or a bulk run for a facility, transit programme or NFC project, tell us the exact Atmel chip and quantity and we confirm the part before production. Security ID Systems supplies genuine Atmel silicon and is independent and not affiliated with Atmel.
