Product details
Overview
ATA5577M1330-DDT from Atmel is a contactless read/write low-frequency RFID identification IC operating at 125–134 kHz, featuring 363-bit EEPROM (11 blocks × 33 bits), load-modulation uplink, and OOK pulse-interval-encoded downlink. It serves as the core transponder chip in passive RFID tags for access control, animal identification, and waste management systems.
For engineers reviewing the ATA5577M1330-DDT datasheet, ATA5577M1330-DDT pinout, ATA5577M1330-DDT application, or ATA5577M1330-DDT equivalent, key selection considerations include ISO/IEC 11784/11785 configurability, T5557/ATA5567 compatibility, block-wise EEPROM programming with lock bits, and on-chip antenna capacitor trimming for coil tolerance.
Technical Context
The ATA5577M1330-DDT integrates an analog front end with rectifier, clock extractor, field-gap detector, and switchable load modulation between Coil1 and Coil2. Its controller manages EEPROM read/write access, mode register shadowing, and protocol decoding per the Atmel e555x downlink standard.
Data-rate generation supports binary-programmable rates from RF/2 to RF/128 plus fixed Basic mode rates (RF/8, RF/16, RF/32, etc.). Modulation options include Manchester, bi-phase, FSK, PSK, and NRZ - all configurable via EEPROM option register settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 100–150 kHz - supports 125 kHz and 134.2 kHz operation bands used in ISO/IEC 11784/11785 animal ID and access control systems |
| EEPROM Capacity | 363 bits (11 × 33-bit blocks) - includes lock bits per block; enables secure, block-level write protection and configuration storage |
| Uplink Modulation | Load modulation - achieves bidirectional communication using single coil for both power harvesting and data transmission |
| Downlink Protocol | Pulse-interval encoding (OOK) - decodes base station commands without external clock; compatible with legacy e5551/T5551 readers |
| On-chip Capacitor | 330 pF ±10 pF (typ.) - reduces external component count and improves antenna tuning tolerance across manufacturing variance |
| Operating Temperature | –40°C to +85°C - qualified for industrial and outdoor RFID tag deployment including livestock tracking and municipal waste bins |
| Data Retention | 20 years at 55°C - ensures long-term reliability of stored ID, traceability, and configuration data in unpowered tags |
Pinout & Package
ATA5577M1330-DDT is supplied in a bare die format with 2-terminal coil interface. The package variant DDT corresponds to the ATA5577M2 pad option: 200 µm × 400 µm bonding pads optimized for direct coil bonding (no wire bond required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Coil 1 | AC input / modulation node | Primary connection to resonant LC tank; participates in RF energy harvesting and load-modulation uplink |
| Coil 2 | AC return / modulation node | Completes coil interface path; forms switchable resistive load path with Coil 1 for backscatter transmission |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 11784/11785 Configurability | Enabled via EEPROM configuration register - allows same die to support animal ID (FDX-B) or access control (EM4102-compatible) protocols |
| Block-wise EEPROM Programming | 33-bit blocks (32 data + 1 lock bit) programmed simultaneously - prevents partial writes and ensures atomic configuration updates |
| High Q-Antenna Tolerance | On-chip trimmable capacitor (330 pF ±10 pF) and clamp voltage options - accommodates ±15% coil inductance variation without retuning |
| Two Operating Modes | Basic mode (fixed data rates) and Extended mode (binary-programmable rates) - balances interoperability with reader flexibility |
| Traceability Data Blocks | Pre-programmed, factory-locked Blocks 1–2 in Page 1 - provides immutable die traceability without consuming user memory space |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| T5557-TS | Fixed 64-bit memory; no on-chip capacitor; requires external tuning capacitor | Limited to Basic mode only; no ISO/IEC 11784/11785 configuration support | Choose for cost-sensitive, legacy-reader-only deployments where EEPROM flexibility and protocol configurability are not required |
| ATA5567-PL | Same 363-bit EEPROM architecture and pinout; different pad layout (ATA5567M1: 100 µm × 100 µm) | Identical functional behavior but optimized for wire-bonded micromodule packaging instead of direct coil bonding | Choose when using wire-bond assembly process or existing ATA5567-based module designs requiring footprint compatibility |
Compared with T5557-TS and ATA5567-PL, the ATA5577M1330-DDT uniquely combines direct-coil-bonding pad geometry, integrated 330 pF capacitor, and full ISO/IEC 11784/11785 configurability - making it optimal for new high-reliability, multi-protocol tag designs requiring minimal external components.

FAQ
What is the primary function of the ATA5577M1330-DDT in an RFID system?
The ATA5577M1330-DDT functions as a passive, contactless read/write transponder IC that harvests power and communicates bidirectionally via a single coil at 125–134 kHz. It stores and transmits identification data using load modulation (uplink) and decodes OOK pulse-interval-encoded commands (downlink), serving as the core IDIC® element in ISO-compliant RFID tags.
Does the ATA5577M1330-DDT support ISO/IEC 11784 and 11785 standards?
Yes, the ATA5577M1330-DDT is configurable for ISO/IEC 11784/11785 compliance via its EEPROM configuration register. This enables FDX-B mode operation required for animal identification, with factory-programmed traceability blocks and user-programmable ID fields - all verified in the official Atmel datasheet revision 4967DS–RFID–10/08.
What is the significance of the "DDT" suffix in ATA5577M1330-DDT?
The "DDT" suffix identifies the specific die variant with ATA5577M2 pad geometry: 200 µm × 400 µm bonding pads designed for direct coil bonding (not wire bonding). This eliminates bond wires, improves mechanical robustness in implantable or ruggedized tags, and aligns with the "M1330" designation indicating 330 pF on-chip capacitor trim.
How does the ATA5577M1330-DDT handle EEPROM write protection?
The ATA5577M1330-DDT implements per-block write protection using a dedicated lock bit (bit 0) in each of its 11 × 33-bit EEPROM blocks. Once set, the lock bit and entire 33-bit block become permanently read-only. Block 0 holds configuration data; Blocks 1–2 contain factory-locked traceability data; user blocks (e.g., 4–7) can be selectively locked post-programming.
Can the ATA5577M1330-DDT replace the e5551/T5551 in existing designs?
Yes, the ATA5577M1330-DDT is documented as a replacement for e5551/T5551 in most common operation modes, including Basic mode and standard downlink protocols. However, full functional equivalence requires validation of modulation parameters, timing margins, and memory map usage - as explicitly stated in section 2 of the Atmel datasheet 4967DS–RFID–10/08.
