The T5577 (also known as ATA5577) is a low-frequency (LF) RFID chip widely used in access control cards, hotel keys, and identification systems. Here is a detailed introduction in English.
1. Basic Definition
The T5577 is a multifunctional contactless read/write IC manufactured by Atmel (now part of Microchip). It operates at the 125 kHz frequency band and is known for its rewritable and configurable nature, making it a common choice for low-security RFID applications.
2. Key Technical Specifications
Parameter | Specification |
Chip | Atmel T5577 / ATA5577 |
Frequency | 125 kHz (LF) |
Memory | 330 bits EPROM (10 blocks of 33 bits) |
Features | Configurable modulation, 8-bit password protection |
Read/Write Distance | Typically 3–10 cm (depends on reader) |
Data Retention | 10 years |
Write Endurance | >100,000 cycles |
The chip includes a configuration block (Block 0) that allows it to emulate other 125 kHz protocols like EM4200 or TK4100, increasing its compatibility with existing readers.
3. Common Applications
- Access Control Systems: Office buildings, residential gates.
- Hotel Key Cards: Widely used as programmable key cards for door locks.
- Animal Identification: LF tags for livestock tracking.
- Industrial Automation: Process control and asset tagging.
4. Card Formats
The chip is typically embedded in standard card form factors:
- CR80 Cards(85.6 × 54 mm, standard credit card size)
- Key Fobs
- Sticker Tagsor Coin Tags
5. Security Note
While T5577 supports a simple 8-bit password, it is considered a low-security RFID technology compared to modern 13.56 MHz (HF) chips like MIFARE or NFC. It is susceptible to cloning if not properly encrypted.
In summary, T5577 is a versatile and cost-effective solution for basic RFID tagging and access control where high security is not the primary requirement.
