Product details
Overview
ATA5577M1330C-DDT from Microchip Technology (formerly Atmel) is a contactless 125–134 kHz LF RFID read/write identification IC with 363-bit EEPROM, load modulation uplink, and OOK pulse-interval downlink decoding. It serves as the core transponder chip in passive RFID tags for access control, animal identification, and waste management systems.
For engineers reviewing the ATA5577M1330C-DDT datasheet, ATA5577M1330C-DDT pinout, ATA5577M1330C-DDT application, or ATA5577M1330C-DDT equivalent, key selection factors include ISO/IEC 11784/11785 configurability, T5557/ATA5567 compatibility, on-chip antenna capacitor options (330 pF nominal), and dual-mode operation (Basic/Extended).
Technical Context
The ATA5577M1330C-DDT integrates an analog front end with rectifier, clock extractor, field-gap detector, and switchable load modulator between Coil1 and Coil2. Its HV generator enables EEPROM programming without external high-voltage sources, and its data-rate generator supports binary-programmable rates from RF/2 to RF/128.
Memory is organized into two pages (Page 0: 8 blocks; Page 1: 4 blocks), each block holding 32 data bits + 1 lock bit. Block 0 stores configuration data not transmitted during reads; Block 3 of Page 1 holds analog front-end option settings; traceability data resides in Blocks 1–2 of Page 1 and is factory-programmed and locked.

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 | No on-chip capacitor; requires external 330 pF resonance capacitor; fixed modulation scheme (no NRZ/FSK) | Lacks ISO/IEC 11784/11785 configurability and factory-traceability blocks | Select when cost-sensitive designs prioritize legacy compatibility over integrated capacitor or advanced modulation |
| ATA5567 | Same pinout and register map; identical memory architecture but no factory-programmed traceability blocks in Page 1 | Supports same Basic/Extended modes and T5557 compatibility but lacks pre-locked traceability data | Choose when full ATA5577 feature set is unnecessary and lower unit cost is critical for high-volume consumer tags |
Compared with T5557 and ATA5567, the ATA5577M1330C-DDT delivers integrated resonance capacitance, ISO-standard configurability, and immutable traceability data - making it optimal for regulated, long-lifecycle, or security-sensitive deployments where board space, field robustness, and data integrity are prioritized.

FAQ
What is the function of the on-chip capacitor in ATA5577M1330C-DDT?
The ATA5577M1330C-DDT integrates a 330 pF ±3% on-chip resonance capacitor (Mask Option M1330), eliminating the need for an external capacitor in the LC tank circuit. This reduces bill-of-materials count and improves design repeatability across antenna variants, especially in space-constrained or high-volume tag assemblies where capacitor placement tolerances impact yield.
Does ATA5577M1330C-DDT support ISO/IEC 11784 and 11785 standards?
Yes, the ATA5577M1330C-DDT is configurable for ISO/IEC 11784/11785 compliance via its EEPROM-based configuration register. This enables use in animal identification systems requiring standardized frame formats, data rates, and modulation schemes - a capability confirmed in Atmel's official application notes and datasheet revision history.
How many times can the EEPROM in ATA5577M1330C-DDT be rewritten?
The ATA5577M1330C-DDT EEPROM is rated for 100,000 write/erase cycles per block, as verified during product qualification. Each of the 11 blocks (32 data bits + 1 lock bit) can be independently programmed and locked; once a lock bit is set, that block becomes permanently read-only, ensuring data integrity in deployed tags.
What are the differences between ATA5577M1330C-DDT and ATA5567?
The ATA5577M1330C-DDT shares register compatibility and Basic/Extended mode operation with ATA5567 but adds factory-programmed traceability data in Page 1 Blocks 1–2 and a fixed 330 pF on-chip capacitor. ATA5567 lacks both features and requires external resonance components, making ATA5577M1330C-DDT preferable for traceable, space-optimized designs.
Can ATA5577M1330C-DDT replace e5551/T5551 in all applications?
The ATA5577M1330C-DDT is documented as a replacement for e5551/T5551 in most common operation modes, including Basic mode and standard data rates. However, full functional equivalence requires validation in the target reader environment, as certain extended command sets or timing margins may differ - particularly in high-interference or marginal-coupling scenarios.
