Description

The Atmel T5577 card is a flexible and cost-effective RFID chip designed for low-frequency applications. Its rewritable memory, compatibility with multiple protocols, and ease of integration make it a popular choice for access control, hotel key cards, and legacy system upgrades. While it lacks advanced security features, the T5577 remains a reliable option for low-security environments and systems requiring backward compatibility.

Atmel ATA5577 card is a contactless read/ write identification IC (IDIC) for applications in 125-kHz or 134-kHz frequency band.

A single coil connected to the chip serves as the IC’s power supply and bi-directional communication interface. The antenna and chip together form a transponder, or tag. The on-chip 363-bit EEPROM (11 blocks with 33 bits each) can be read and written block-wise from a base station (reader). Data is transmitted from the IDIC (uplink) using load modulation.

This is achieved by damping the RF field with a resistive load between the two terminals Coil 1 and Coil 2. The IC receives and decodes serial base station commands (downlink) which are encoded as 100% amplitude modulated (OOK) pulse-interval-encoded bit streams.

Applications of Atmel T5577 card

Access Control Systems: Frequently used in office buildings, gated communities, and secure facilities for access cards and key fobs.

Hotel Key Cards: Ideal for hotels to control room access and services.

Parking Systems: Used in parking lot access and vehicle identification systems.

Legacy System Integration: The T5577’s ability to emulate older protocols like EM4100 makes it a great option for upgrading or replacing outdated systems without changing the infrastructure.

Identification and Authentication: Used in employee ID cards, visitor passes, and other identification cards.

Advantages of Atmel T5577 card

Rewritable and Reprogrammable: Can be reused and reprogrammed for different applications.

Protocol Flexibility: Compatible with multiple protocols, making it a universal solution for low-frequency RFID systems.

Cost-Effective: Affordable for high-volume applications like hotel key cards and access control.

Backward Compatibility: Ideal for replacing legacy RFID chips without changing existing hardware.

The Operation Principle of Atmel T5577 card

Inductive Coupling:

The T5577 chip is powered passively by the electromagnetic field generated by the RFID reader.

Data Exchange:

The chip communicates with the reader using ASK or FSK modulation, depending on its configuration.

Programmability:

Using an RFID writer, the memory of the T5577 can be programmed to emulate specific protocols or store identification data.

Emulation:

The chip can mimic other low-frequency RFID protocols, allowing it to replace cards like EM4100 or HID Prox in existing systems.
