Product details
Overview
ATA5577M1330C-DDB from Microchip Technology is a contactless read/write LF RFID identification IC operating at 125 kHz or 134 kHz, featuring 363-bit EEPROM (11 × 33-bit blocks), load-modulated uplink communication via Coil 1/Coil 2 terminals, and OOK/PIE downlink decoding. It serves as the core transponder IC in animal ID tags, access control tokens, and waste management tags.
For engineers reviewing the ATA5577M1330C-DDB datasheet, ATA5577M1330C-DDB pinout, ATA5577M1330C-DDB application, or ATA5577M1330C-DDB equivalent, key selection criteria include ISO/IEC 11784/11785 configurability, password-protected write access, soft modulation switching for high-Q antenna compatibility, and binary-selectable data rates from RF/2 to RF/128.
Technical Context
The ATA5577M1330C-DDB integrates an analog front end with on-chip rectifier, clock extractor, field gap detector, and switchable resistive load modulator between Coil 1 and Coil 2. Its controller executes blockwise EEPROM read/write, loads Mode and Option registers from EEPROM after POR, and enforces lock-bit protection per 33-bit block.
It supports two operational modes: Basic mode with fixed data rates (RF/8–RF/128) and Extended mode enabling binary-programmable data rates, OTP functionality, inverse data output, and fast downlink (~6 kbps). Configuration is stored in EEPROM Block 0 (mode register) and Block 3, Page 1 (AFE option register), both preprogrammed at delivery.

FAQ
What is the primary function of the ATA5577M1330C-DDB in an RFID system?
The ATA5577M1330C-DDB functions as a passive, contactless read/write identification IC that harvests power from a 125 kHz or 134 kHz reader field and communicates via load modulation between its Coil 1 and Coil 2 terminals. It stores 363 bits of EEPROM data-including user memory, unique ID, and configuration registers-and supports ISO/IEC 11784/11785-compliant animal ID applications. The ATA5577M1330C-DDB replaces legacy devices like T5557 while adding OTP locking and soft modulation for improved reliability.
Does the ATA5577M1330C-DDB require an external power supply or battery?
No, the ATA5577M1330C-DDB operates entirely without external power or battery. It derives its supply voltage from the alternating magnetic field generated by an LF RFID reader through the external antenna coil connected to Coil 1 and Coil 2. On-chip rectification and regulation convert this RF energy into usable DC voltage for internal circuitry and EEPROM programming. This makes the ATA5577M1330C-DDB ideal for maintenance-free, implantable, or disposable RFID tags.
How does the ATA5577M1330C-DDB support ISO/IEC 11784/11785 compliance?
The ATA5577M1330C-DDB supports ISO/IEC 11784/11785 compliance through configurable AFE and modulation parameters stored in its EEPROM Option register (Block 3, Page 1) and Configuration register (Block 0). Factory-programmed traceability data-including Allocation Class (ACL = E0h), Manufacturer Code (MFC = 15h), and Chip ID (CID = 00001b)-are embedded in Blocks 1 and 2 of Page 1 and transmitted upon reader request. The ATA5577M1330C-DDB enables full standard alignment without hardware modification.
What memory protection mechanisms does the ATA5577M1330C-DDB provide?
The ATA5577M1330C-DDB implements three-tiered memory protection: per-block lock bits (1 per 33-bit block), password-protected write access (using Block 7 as 32-bit password memory), and One-Time-Programmable (OTP) mode activated by setting OTP = 1 and master key = 6. Once locked, a block cannot be rewritten via RF field; OTP mode permanently disables all further writes. These features ensure data integrity in regulated applications such as animal ID and secure access control using the ATA5577M1330C-DDB.
Can the ATA5577M1330C-DDB be used with high-Q antennas, and how is compatibility ensured?
Yes, the ATA5577M1330C-DDB is explicitly designed for high-Q antenna compatibility. It achieves this through soft modulation switching-configurable transition ramps that prevent abrupt signal edges-and adjustable AFE parameters (clamping voltage, modulation level, clock/gap detection thresholds) stored in the Option register. These features mitigate clock loss and timing violations common in high-Q systems. The ATA5577M1330C-DDB also includes on-chip 250 pF ±3% trimming capacitance to simplify antenna tuning at 125 kHz.
