Product details
Overview
ATA5577M1330-DDB 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 a transponder tag IC powered and communicated via a single external coil, used in animal ID, access control, and waste management systems.
For engineers reviewing the ATA5577M1330-DDB datasheet, ATA5577M1330-DDB pinout, ATA5577M1330-DDB application, or ATA5577M1330-DDB equivalent, key selection considerations include ISO/IEC 11784/11785 compatibility mode, programmable data rates (RF/8 to RF/128), on-chip trimmed antenna capacitor (330 pF typ.), block-wise EEPROM write protection, and T5557/ATA5567 functional equivalence.
Technical Context
The ATA5577M1330-DDB integrates an analog front end with rectifier, clock extractor, field-gap detector, and switchable load modulator between Coil1 and Coil2. Its controller executes EEPROM read/write, mode register shadowing, and downlink command decoding per the Atmel e555x protocol.
Data-rate generation supports binary-programmable even divisors 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 for global LF RFID compliance. |
| EEPROM Capacity | 363 bits (11 × 33-bit blocks) - includes lock bits per block; enables secure, segmented user and configuration data storage. |
| Modulation Scheme | Load modulation uplink + OOK pulse-interval downlink - enables bidirectional communication using single coil without external power. |
| Configurable Data Rates | RF/8 to RF/128 (even divisors) - allows tuning for reader compatibility and noise immunity in varying field strengths. |
| On-chip Capacitor | 330 pF ±10 pF (typ.) - reduces external component count and improves antenna Q-tolerance in compact tag designs. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and outdoor deployment including animal tagging and waste bin tracking. |
| EEPROM Endurance | 100,000 write/erase cycles - ensures long-term reprogrammability in reusable access tokens or serviceable asset tags. |
Pinout & Package
ATA5577M1330-DDB is supplied in a bare die format with 200 µm × 400 µm pad layout optimized for direct coil bonding (ATA5577M2 variant). No wire-bond pads or leadframe package is used.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Coil 1 | AC input / modulation node | Primary connection to resonant LC tank; participates in RF power harvesting and load modulation during uplink transmission. |
| Coil 2 | AC return / modulation node | Completes coil interface path; internal switch connects Coil1–Coil2 under controller command to damp RF field for data encoding. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 11784/11785 Configurability | Enables compliance with international animal identification standards via EEPROM-configured modulation and protocol parameters. |
| Block-wise EEPROM Lock Bits | Each of 11 memory blocks has dedicated lock bit; prevents accidental overwrite of critical configuration or traceability data after programming. |
| High-Q Antenna Tolerance | Integrated trim options and clamp voltage control (11–17 V range) maintain stable operation across variable coil quality factors and coupling distances. |
| Two Operational Modes | Basic Mode (fixed data rates) and Extended Mode (binary-programmable rates) support interoperability with legacy and advanced readers respectively. |
| Traceability Data Blocks | Factory-programmed, non-transmitted blocks (Page 1, Blocks 1–2) provide unique device traceability without exposing sensitive data during normal read operations. |
Applications
| Animal Identification | Access Control |
|---|---|
Use Scenario: Implantable or ear-tag RFID transponders for livestock and pets operating in uncontrolled electromagnetic environments. IC Role / Device Role / Timing Role: Passive transponder IC providing ISO-compliant ID transmission and secure reprogramming via handheld reader.

IC Role / Device Role / Timing Role: Ruggedized passive tag IC with extended temperature range (–40°C to +85°C) and high endurance EEPROM. Use Value: 100,000-cycle EEPROM endurance supports repeated reprogramming during bin lifecycle; load modulation ensures reliable reads despite metal proximity and environmental contamination. | Use Scenario: Tooling or equipment tags in factory automation systems requiring maintenance logging and calibration verification. IC Role / Device Role / Timing Role: Read/write transponder storing calibration date, operator ID, and usage counters accessible via fixed-mount readers. Use Value: Dual-page memory architecture separates factory-traceable data (Page 1) from field-updatable records (Page 0), enforcing data integrity and audit readiness. |
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 structure and Basic/Extended mode support; lacks on-chip 330 pF capacitor and ISO/IEC 11784/11785 configuration bits. | Requires external capacitor for resonance tuning; limited to legacy reader protocols without ISO standardization. | Select T5557 only when cost sensitivity outweighs need for integrated capacitor and ISO compliance. |
| ATA5567 | Pin-compatible and functionally identical architecture; differs only in mask option coding (M1 vs M2 pad layout) and minor electrical tolerances. | No functional difference in system integration; same memory map, modulation, and protocol behavior. | Choose ATA5567 if existing design uses ATA5577M1 (100 µm × 100 µm) wire-bond pad variant instead of ATA5577M2 (200 µm × 400 µm) direct-coil layout. |
Compared with T5557 and ATA5567, the ATA5577M1330-DDB provides tighter integration via on-die 330 pF capacitor and explicit ISO/IEC 11784/11785 configuration capability - reducing BOM count and accelerating certification for animal ID and regulated access systems.

FAQ
What is the primary function of the ATA5577M1330-DDB in an RFID system?
The ATA5577M1330-DDB functions as a passive, contactless read/write transponder IC. It harvests power from a 125–134 kHz RF field via an external coil, stores data in its 363-bit EEPROM, and communicates bidirectionally using load modulation (uplink) and OOK pulse-interval decoding (downlink). The ATA5577M1330-DDB operates without a battery and is embedded directly into tags for animal ID, access control, and waste management.
Does the ATA5577M1330-DDB support ISO/IEC 11784 and ISO/IEC 11785 standards?
Yes, the ATA5577M1330-DDB is configurable for full ISO/IEC 11784/11785 compliance via its EEPROM-based option register. This enables standardized animal identification protocols including FDX-B frame format, data rate selection, and modulation parameters - verified in the official Atmel datasheet revision 4967DS–RFID–10/08. Configuration is performed during initial programming of the ATA5577M1330-DDB.
What is the significance of the "M1330" suffix in ATA5577M1330-DDB?
The "M1330" suffix denotes the mask option and pad layout variant: M2 (200 µm × 400 µm) for direct coil bonding, with a nominal on-die resonance capacitor of 330 pF. This distinguishes it from the M1 variant (100 µm × 100 µm, 330 pF) and other capacitance options (e.g., M1242 = 250 pF). The "DDB" suffix indicates tape-and-reel packaging for automated assembly. The ATA5577M1330-DDB is not a module but a bare die.
How does the ATA5577M1330-DDB handle EEPROM write protection?
The ATA5577M1330-DDB implements per-block write protection using dedicated lock bits - one per 33-bit EEPROM block. Once a lock bit is set (programmed to '1'), the entire block (including the lock bit itself) becomes permanently read-only. Block 0 contains configuration data and is protected by default; Block 7 may serve as a password location. This hardware-enforced locking ensures data integrity in deployed ATA5577M1330-DDB tags.
Can the ATA5577M1330-DDB replace the T5551 or e5551 in existing designs?
The ATA5577M1330-DDB is documented as a replacement for e5551/T5551 in most common operation modes, with identical configuration register structure and Basic/Extended mode support. However, functional equivalence requires validation of modulation type, data rate, and memory access sequence in the target reader environment. The ATA5577M1330-DDB adds ISO/IEC 11784/11785 configurability and on-chip capacitor not present in e5551.
