Product details
Overview
ATA5577M1330C-PAE 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-PAE datasheet, ATA5577M1330C-PAE pinout, ATA5577M1330C-PAE application, or ATA5577M1330C-PAE equivalent, key selection considerations include its ISO/IEC 11784/11785 configurability, T5557/ATA5567 compatibility, soft modulation switching, OTP capability, and pad-type–specific coil interface design.
Technical Context
The ATA5577M1330C-PAE 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 power.
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), configurable modulation schemes (Manchester, Bi-phase, FSK, PSK, NRZ), and features including password protection, Answer-On-Request (AOR), Maxblock addressing, and inverse data output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 125 kHz or 134 kHz - matches standard LF RFID reader field frequencies for reliable coupling and regulatory compliance. |
| EEPROM Capacity | 363 bits (11 × 33-bit blocks) - provides 224 bits of user memory, 64 bits for unique ID, and 32-bit option/configuration registers with per-block lock bits. |
| Uplink Modulation | Load modulation via resistive damping between Coil 1 and Coil 2 - enables passive backscatter communication without onboard oscillator or transmitter. |
| Downlink Protocol | 100% OOK Pulse Interval Encoding (PIE) - decodes reader commands using field-gap timing, compatible with legacy T5557 infrastructure. |
| Data Rate Range | RF/2 to RF/128 (Extended mode) or fixed RF/8–RF/128 (Basic mode) - supports flexible read speed vs. range trade-offs across diverse antenna Q factors. |
| Memory Protection | Per-block lock bit + OTP mode (master key = 6) - prevents reprogramming after final configuration, ensuring tamper-resistant tag identity. |
| Init Delay | Configurable ~69 ms (init delay = 1) or ~3 ms (init delay = 0) - controls time-to-first-response for anti-collision sequencing and low-power wake-up timing. |
Pinout & Package
ATA5577M1330C-PAE uses a die-only form factor with two bond pads optimized for direct coil bonding: Coil 1 and Coil 2. No external power supply or digital I/O pins are present - all functionality is powered and communicated through the resonant LC tank formed by the external coil and on-chip 250 pF/330 pF trimmed capacitor.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Coil 1 | RF input / modulation node | Primary terminal for AC coil voltage rectification, clock extraction, and resistive load switching during uplink transmission. |
| Coil 2 | RF return / modulation node | Completes the RF path; combined with Coil 1, forms bidirectional interface for power harvesting and load-modulated data transmission. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip trimmed capacitor | 250 pF or 330 pF (±3%) - reduces external component count and tuning effort for 125/134 kHz resonance with standard coil inductances. |
| Soft modulation switching | Configurable transition ramp - minimizes clock loss and timing violations in high-Q antenna systems by smoothing modulation onset. |
| ISO/IEC 11784/11785 setup | Configurable via Option register - enables compliance with international animal identification standards without hardware change. |
| Answer-On-Request (AOR) | Wake-up via opcode + password - allows selective activation in multi-tag fields, reducing interference and enabling deterministic anti-collision protocols. |
| Traceability data structure | Factory-programmed 40-bit unique ID + ACL/MFC/CID/ICR - provides wafer-level traceability (year/quarter/lot/wafer/die) for quality control and counterfeit prevention. |

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-TS8 | Fixed Basic mode only; no Extended mode, OTP, or soft modulation; 264-bit EEPROM (8 × 33-bit); no factory-traceable UID. | Limited to legacy systems requiring strict T5557 pinout and command set; no ISO/IEC 11784 setup or AOR mode. | Select when backward compatibility with existing T5557 firmware and minimal feature set are mandatory. |
| ATA5567-PLQ | Same architecture and register map as ATA5577C but lacks OTP mode, init delay control, and extended traceability data; 363-bit EEPROM with identical block layout. | Suitable for cost-sensitive applications needing T5557 replacement and basic ISO/IEC 11784 support, but not requiring permanent lockdown or wafer-level traceability. | Select when full ATA5577C feature set is unnecessary and lower unit cost is prioritized over OTP and enhanced traceability. |
Compared with T5557-TS8 and ATA5567-PLQ, the ATA5577M1330C-PAE delivers extended configurability (X-mode), factory-programmed traceability, and OTP security - making it optimal for new designs requiring future-proofing, regulatory compliance, and anti-counterfeiting assurance.

FAQ
What is the primary function of the ATA5577M1330C-PAE in an RFID system?
The ATA5577M1330C-PAE 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. It stores and transmits identity data using its 363-bit EEPROM, serving as the core transponder chip in LF RFID tags. Unlike active ICs, the ATA5577M1330C-PAE contains no internal power source and relies entirely on electromagnetic coupling for operation.
Does the ATA5577M1330C-PAE support ISO/IEC 11784 and 11785 standards?
Yes, the ATA5577M1330C-PAE supports ISO/IEC 11784/11785 compliance through configurable settings in its EEPROM Option register. It includes factory-programmed traceability data with Allocation Class (ACL = E0h) and Manufacturer Code (MFC = 15h) aligned to the standards, and allows user configuration of modulation, data rate, and protocol parameters to meet regional animal ID requirements.
How does the ATA5577M1330C-PAE differ from the T5557 in terms of memory and configuration?
The ATA5577M1330C-PAE offers 363-bit EEPROM (11 × 33-bit blocks) versus T5557's 264-bit (8 × 33-bit), adds Extended mode with binary-selectable data rates (RF/2 to RF/128), OTP lockdown, soft modulation, and factory-programmed traceability. Its Configuration and Option registers mirror T5557 layout for compatibility, but extend functionality without breaking legacy command sets.
Can the ATA5577M1330C-PAE be used with high-Q antennas, and how is stability ensured?
Yes, the ATA5577M1330C-PAE is explicitly designed for high-Q antenna tolerance via soft modulation switching, adjustable gap detection thresholds, and configurable write damping. These features mitigate clock loss and timing violations common in high-efficiency coils, and the on-chip 250 pF/330 pF trimmed capacitor further stabilizes resonance without external tuning components.
What is the purpose of the init delay setting in the ATA5577M1330C-PAE?
The init delay setting in the ATA5577M1330C-PAE configures the time (~3 ms or ~69 ms) between RF field application and first modulation response. When enabled (init delay = 1), it extends the initialization window to support robust anti-collision sequencing in dense tag fields and ensures reliable configuration loading before uplink begins - critical for deterministic AOR and multi-tag polling scenarios.
