Product details
Overview
ATA5577M1330C-UFQW 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 modulation uplink, and OOK/PIE downlink decoding. It serves as the core transponder IC in passive RFID tags for access control, animal identification, and waste management systems.
For engineers reviewing the ATA5577M1330C-UFQW datasheet, ATA5577M1330C-UFQW pinout, ATA5577M1330C-UFQW application, or ATA5577M1330C-UFQW equivalent, this page delivers verified technical context, exact memory mapping, modulation protocol support (Manchester, FSK, PSK, NRZ), ISO/IEC 11784/785 configurability, and validated alternatives for tag design and replacement.
Technical Context
The ATA5577M1330C-UFQW integrates an analog front end with on-chip rectifier, clock extractor, field gap detector, and switchable resistive load between Coil 1 and Coil 2 for uplink modulation. Its HV generator enables EEPROM programming via RF field coupling without external voltage.
It supports two operational modes: Basic mode with fixed data rates (RF/8 to RF/128) and Extended mode with binary-selectable rates (RF/2 to RF/128), plus OTP lock, password protection, AOR wake-up, and inverse data output - all configured via dedicated EEPROM registers (block 0 for mode, block 3 page 1 for AFE options).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 125 kHz or 134 kHz - matches standard LF RFID reader field frequencies for reliable coil coupling and power harvesting. |
| EEPROM Capacity | 363 bits (11 × 33-bit blocks) - includes 7×32-bit user memory, 2×32-bit unique ID, 1×32-bit option register, and 1×32-bit configuration register. |
| Uplink Modulation | Resistive load modulation - enables bidirectional communication using single coil; no external components required for basic operation. |
| Downlink Protocol | 100% OOK with PIE encoding - decodes reader commands via pulse interval timing; supports Fast Downlink (~6 kbps) in Extended mode. |
| Data Rate Options | RF/2 to RF/128 (binary-selectable) or fixed RF/8–RF/128 - allows tuning for read range vs. noise immunity trade-offs in varying antenna Q environments. |
| Memory Protection | Per-block lock bit + OTP bit + master key (6 or 9) - provides hardware-level write protection; master key = 6 permanently locks configuration in One-Time-Programmable mode. |
| ISO Compatibility | Configurable for ISO/IEC 11784/785 - enables compliance with animal identification standards via EEPROM-based setup of modulation and data format. |
Pinout & Package
Package: UFQW - ultra-thin flip-chip wafer-level chip-scale package (WLCSP), 100 μm × 100 μm die size, optimized for direct bonding to miniature coil antennas in compact RFID tags.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Coil 1 | RF input / power harvest node | Primary terminal for AC coil voltage rectification; connects to one end of resonant LC tank for energy extraction and clock generation. |
| Coil 2 | RF return / modulation node | Second coil terminal; forms switchable resistive load path with Coil 1 to enable load modulation uplink transmission. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip trimmed capacitor | 250 pF ±3% - reduces external component count and improves resonance stability across production lots. |
| Soft modulation switching | Configurable transition ramp - prevents clock loss during modulation onset, critical for high-Q antenna designs. |
| Answer-On-Request (AOR) | Wake-up via opcode + password - enables anti-collision in multi-tag fields and extends battery-free tag lifetime by suppressing idle modulation. |
| Traceability data structure | Factory-programmed 40-bit unique ID (lot/year/quarter/wafer/die) - supports supply chain traceability and counterfeit detection per ISO/IEC 15963-1. |
| High Q-antenna tolerance | Adjustable AFE thresholds and damping - maintains reliable operation across coil quality variations without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LF RFID transponder IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| T5557 | Same 363-bit EEPROM architecture and PIE downlink; lacks OTP lock, AOR mode, and ISO/IEC 11784/785 configurability. | Supports legacy access control systems but not animal ID compliance or advanced anti-collision. | Select when backward compatibility with existing T5557 infrastructure is required and extended features are unnecessary. |
| ATA5567 | Pin-compatible variant with identical memory map and modulation schemes; differs only in factory-trimmed capacitor value (330 pF vs. 250 pF). | Suitable for same applications but requires antenna retuning if substituting in high-Q coil designs. | Choose when higher capacitance is needed to match specific coil inductance for optimal resonance at 134.2 kHz. |
Compared with T5557 and ATA5567, the ATA5577M1330C-UFQW adds OTP locking, AOR wake-up, and ISO/IEC 11784/785 setup capability - enabling secure, standards-compliant, and collision-resistant tag deployment without layout changes.

FAQ
What is the primary function of the ATA5577M1330C-UFQW in an RFID system?
The ATA5577M1330C-UFQW functions as a passive, contactless read/write identification IC that harvests power from a 125 kHz or 134 kHz RF field and communicates bidirectionally using load modulation (uplink) and OOK/PIE decoding (downlink). As the core transponder IC in ATA5577M1330C-UFQW-based tags, it stores and transmits identity data while supporting password protection, OTP locking, and ISO/IEC 11784/785 configuration.
Does the ATA5577M1330C-UFQW require external components for basic operation?
No, the ATA5577M1330C-UFQW operates with only a single external coil connected between Coil 1 and Coil 2. Its integrated rectifier, clock extractor, HV generator, and 250 pF ±3% on-chip capacitor eliminate the need for external diodes, regulators, or tuning capacitors in standard LF RFID tag implementations.
How is memory organized and protected in the ATA5577M1330C-UFQW?
The ATA5577M1330C-UFQW contains 363 bits of EEPROM arranged in 11 blocks of 33 bits each (32 data + 1 lock bit). Block 0 holds configuration data, blocks 1–7 store user memory (including password), and blocks 1–2 of page 1 contain factory-programmed traceability data. Each block is individually lockable; setting the OTP bit with master key = 6 permanently disables all writes.
What modulation schemes does the ATA5577M1330C-UFQW support for uplink transmission?
The ATA5577M1330C-UFQW supports Manchester, Bi-phase, FSK, PSK, and NRZ modulation schemes for uplink transmission - all selectable via its EEPROM configuration register. In Extended mode, it additionally supports inverse data output and differential bi-phase encoding, enabling interoperability with diverse reader protocols including ISO/IEC 11784/785.
Is the ATA5577M1330C-UFQW compatible with existing T5557-based infrastructure?
Yes, the ATA5577M1330C-UFQW is designed to be compatible with T5557 and ATA5567 systems: it uses identical memory mapping, PIE downlink protocol, and Basic/Extended mode structure. However, use of Extended mode features (e.g., OTP, AOR) requires reader firmware updates; for drop-in replacement in legacy systems, configure ATA5577M1330C-UFQW to match T5557 default settings.
