Product details
Overview
ATA5575M2330-DDB from Microchip Technology (formerly Atmel) is a contactless read/write low-frequency RFID identification IC optimized for ISO/IEC 11784/11785 FDX-B animal identification. It operates at 100–150 kHz, integrates 128-bit EEPROM user memory and 8-bit configuration memory, features on-chip 330 pF ±3% antenna capacitor, and supports load-modulated uplink with differential biphase or FSK2 encoding. Used in implantable and ear-tag transponders requiring reliable field-powered operation.
For engineers reviewing the ATA5575M2330-DDB datasheet, ATA5575M2330-DDB pinout, ATA5575M2330-DDB application, or ATA5575M2330-DDB equivalent, key selection criteria include ISO11785 FDX-B compliance, 128-bit programmable UID storage, coil-driven power harvesting, lock-bit memory protection, and direct coil bonding via 200 µm × 400 µm mega pads with gold bumps.
Technical Context
The ATA5575M2330-DDB implements a fully integrated analog front end with RF rectifier, clock extractor, field-gap detector, and switchable resistive load modulator between Coil1 and Coil2. Its controller executes pulse-interval-encoded downlink command decoding (RESET, Read ID, Write Byte, Direct Access) and manages EEPROM access with byte-wise programming verified by internal HV generator.
Memory architecture comprises 17 bytes (136 bits) of EEPROM: bytes 0–15 hold user data (128 bits), byte 16 stores configuration including lock bits, modulation mode (differential biphase RF/32 or FSK2 RF/50), and ID length. Configuration is loaded at POR and mirrored in a mode register; factory delivery state sets byte 16 = 0x09 for FDX-B, memory reprogrammable, and 128-bit ID output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 100–150 kHz - Enables operation in ISO11784/11785 FDX-B band (134.2 kHz) and FDX-A (125 kHz) with configurable data rate. |
| User Memory | 128-bit EEPROM (16 bytes × 8 bits) - Stores animal UID, country code, trailer, and CRC per ISO11785 telegram structure. |
| Configuration Memory | 8-bit EEPROM (byte 16) - Controls lock bits, modulation type, ID length, and enables memory locking to prevent field reprogramming. |
| On-Chip Capacitor | 330 pF ±3% - Matches standard 134.2 kHz coil inductance without external components; reduces tuning sensitivity and improves antenna Q tolerance. |
| Modulation Schemes | Differential biphase RF/32 & FSK2 RF/50 - Supports ISO11785-compliant uplink transmission with defined bit encoding and timing for reader interoperability. |
| Programming Time | 5.6 ms typical per byte - Includes erase, verify, program, and final verification; ensures data integrity before entering byte-read mode. |
| Data Retention | 10–50 years at 55°C - Guaranteed EEPROM data persistence under industrial/animal ID operating conditions per qualification testing. |
| Operating Temp | –40°C to +85°C - Validated for embedded use in outdoor livestock environments and industrial traceability systems. |
Pinout & Package
ATA5575M2330-DDB is supplied as a bare die on 6-inch sawn wafer mounted on UV-release foil with ring frame (thickness ≈150 µm). It features two mega pads (200 µm × 400 µm) with 25 µm gold bumps for direct wire bonding to antenna coil terminals. No conventional package; coil connections are made directly to Coil1 and Coil2 terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Coil1 | RF input / power harvest node | AC terminal for antenna coil connection; supplies rectified DC voltage and receives OOK-encoded downlink commands via field gaps. |
| Coil2 | RF return / modulation node | Completes LC tank; enables load modulation by switching resistive path between Coil1 and Coil2 for uplink data transmission. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 11784/11785 Compliance | Fully implements FDX-B telegram structure including 38-bit unique number, 16-bit CRC, and 24-bit trailer for regulatory animal ID systems. |
| Factory-Preprogrammed UID | Delivers unique 12-decimal production ID (lot, wafer, die-on-wafer) preloaded in EEPROM bytes 0–15 per Atmel's traceability scheme. |
| Memory Lock Protection | Configurable lock bits (bits 1–5 of byte 16) enable permanent write-protection after programming - prevents unauthorized UID overwrite in deployed tags. |
| Direct Coil Bonding Interface | 200 µm × 400 µm gold-bumped mega pads support robust, low-inductance attachment to antenna coils without bond wires or substrates. |
| High-Q Antenna Tolerance | On-chip 330 pF capacitor and adaptive AFE reduce sensitivity to coil parameter variation, enabling consistent read range across manufacturing batches. |
| Field-Powered Operation | No external power required - derives all supply and clock from reader's RF field via integrated rectifier and clock extractor. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATA5577C-PLW | Read-only (ROM) architecture; no EEPROM; fixed 64-bit UID; no lock-bit configuration; 250 pF on-chip cap. | Suitable only for static ID applications; cannot be field-programmed or updated post-manufacture. | Select when cost-sensitive, single-use tagging is required and UID permanence is guaranteed at wafer level. |
| EM4102-RC | Passive 125 kHz IDIC with 64-bit ROM; no programmable memory; no on-chip capacitor; requires external tuning. | Limited to basic read-only identification; lacks ISO11785 FDX-B structure, CRC, or trailer fields. | Choose for legacy 125 kHz readers where ISO compliance is not mandated and minimal BOM count is critical. |
Compared with ATA5575M2330-DDB, ATA5577C-PLW offers lower unit cost but forfeits field reprogrammability and ISO11785 telegram flexibility, while EM4102-RC provides broad reader compatibility at the expense of regulatory compliance and data integrity features like CRC and lock protection.

FAQ
What is the primary function of the ATA5575M2330-DDB in an RFID system?
The ATA5575M2330-DDB serves as a contactless, field-powered read/write identification IC that forms the core of ISO11784/11785-compliant RFID transponders. It harvests energy from a reader's RF field via its coil interface, stores and retrieves 128-bit UID data in EEPROM, and transmits it using load modulation. The ATA5575M2330-DDB supports both FDX-A and FDX-B modes, with factory default configured for FDX-B animal ID applications.
How does the on-chip 330 pF capacitor in the ATA5575M2330-DDB improve system design?
The integrated 330 pF ±3% capacitor eliminates the need for external tuning components in 134.2 kHz antenna circuits, reducing bill-of-materials count and assembly complexity. It enhances antenna Q tolerance by compensating for coil inductance variations, resulting in more consistent read range across production units and environmental conditions. This feature is specific to the ATA5575M2330-DDB variant and directly supports ISO11785 FDX-B compliance.
Can the ATA5575M2330-DDB be reprogrammed after initial deployment?
Yes - the ATA5575M2330-DDB supports field reprogramming of its 128-bit EEPROM user memory via downlink commands until memory lock bits in byte 16 are set. Once locked (e.g., with lock bits = '01101b'), the entire EEPROM becomes permanently read-only. This dual-mode capability allows flexible provisioning during manufacturing or depot maintenance, followed by secure, tamper-resistant operation in the field - a key behavior of the ATA5575M2330-DDB.
What are the physical interface requirements for connecting an antenna to the ATA5575M2330-DDB?
The ATA5575M2330-DDB uses two 200 µm × 400 µm mega pads with 25 µm gold bumps for direct bonding to antenna coil terminals. These pads are designed for wedge or ball bonding to copper or aluminum coil leads without intermediate substrates. No wire bonds or solder are required; mechanical and electrical integrity relies on bump compression and ultrasonic bonding. This interface is specified in the DDB package variant and differs from DBB/DBN variants with alternate bump configurations.
Does the ATA5575M2330-DDB support both FDX-A and FDX-B communication protocols?
Yes - the ATA5575M2330-DDB supports both ISO11785 FDX-A (RF/50 data rate) and FDX-B (RF/32) modes via configuration byte 16. Factory delivery defaults to FDX-B (byte 16 = 0x09), but users can reconfigure modulation type, ID length, and lock status. FDX-A mode uses FSK2 encoding and 96-bit ID, while FDX-B uses differential biphase and 128-bit ID - both are fully implemented in the ATA5575M2330-DDB's modulator and controller logic.
