Product details
Overview
ATA5575M2250-DBB from Microchip Technology (formerly Atmel) is a contactless read/write low-frequency RFID identification IC operating in the 100–150 kHz band. It functions as a passive transponder powered and communicated with via a single external coil, features 128-bit user EEPROM (16 bytes), 8-bit configuration memory, on-chip trimmed antenna capacitor of 250 pF ±3%, and supports ISO/IEC 11784/11785 FDX-A and FDX-B protocols for animal identification.
For engineers reviewing the ATA5575M2250-DBB datasheet, ATA5575M2250-DBB pinout, ATA5575M2250-DBB application, or ATA5575M2250-DBB equivalent, this page delivers verified technical context, exact pin functionality, real-world use cases in traceable ID systems, and validated alternative options - all grounded in the official 9217F-RFID-12/14 datasheet and Microchip ordering documentation.
Technical Context
The ATA5575M2250-DBB integrates an analog front end with rectifier, clock extractor, field-gap detector, and switchable load modulator between Coil 1 and Coil 2 for uplink transmission. Its controller executes pulse-interval-encoded downlink command decoding (RESET, Read ID, Write Byte, Direct Access) and manages EEPROM access with lock-bit protection.
It implements two programmable data rates: RF/50 for FDX-A mode and RF/32 for FDX-B mode, with modulation options including Differential Biphase and FSK2. Memory consists of 136-bit EEPROM (17 × 8-bit bytes), where byte 16 holds configuration data controlling ID length (64/96/128 bits), modulation type, and memory lock state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 100–150 kHz - Enables operation across ISO 11784/11785 FDX-A (125 kHz) and FDX-B (134.2 kHz) bands with field tolerance. |
| User Memory | 128-bit EEPROM (16 bytes) - Stores animal ID, country code, unique number, and CRC per ISO FDX-B telegram structure. |
| Configuration Memory | 8-bit EEPROM (byte 16) - Controls ID length, modulation scheme, and memory lock bits; loaded at POR and used to initialize mode register. |
| On-Chip Capacitor | 250 pF ±3% - Reduces external component count; matches typical 134.2 kHz coil resonance without discrete capacitor. |
| Data Rate Options | RF/32 (FDX-B) or RF/50 (FDX-A) - Selectable via configuration byte; determines bit timing and telegram structure compliance. |
| Modulation Schemes | Differential Biphase (RF/32) or FSK2 (RF/50) - Determines encoding method for uplink transmission to reader; affects read range and noise immunity. |
| Memory Endurance | 100,000 write/erase cycles - Guarantees long-term reprogramming capability during tag personalization before final lock. |
| Data Retention | 20 years at +55°C - Ensures reliable UID storage over full operational lifetime in embedded animal ID implants. |
Pinout & Package
ATA5575M2250-DBB is supplied as a bare die on 6-inch wafer foil with gold bumps (25 µm height), packaged in ring frame format (Microchip package code DBB). Die dimensions are 0.966 mm × 0.402 mm with mega pads sized 200 µm × 400 µm. The device has two terminals only: Coil 1 and Coil 2 - both serve as bidirectional interface for power harvesting and load-modulated data transmission.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Coil 1 | RF Interface Terminal | Connects to one end of external antenna coil; forms resonant LC tank with on-chip 250 pF capacitor and enables contactless power extraction and uplink modulation. |
| Coil 2 | RF Interface Terminal | Connects to other end of external antenna coil; completes LC tank and provides return path for rectified supply and resistive load switching during uplink. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 11784/11785 Compliance | Fully supports FDX-A and FDX-B telegram formats out-of-box; pre-configured for FDX-B delivery mode with UID traceability. |
| On-Chip Antenna Capacitor | 250 pF ±3% - Eliminates need for external tuning capacitor in 134.2 kHz animal ID applications, simplifying coil design and assembly. |
| Memory Lock Protection | Configurable lock bits (bits 1–5 of byte 16) enable irreversible memory locking after programming - critical for tamper-resistant animal ID deployment. |
| Direct Access Mode | Supports byte-level read via '10' opcode + 5-bit address - allows selective verification of programmed data without full ID transmission. |
| High Q-Antenna Tolerance | Built-in capacitor trimming and robust field-gap detection enable stable operation across coil Q variations encountered in implantable tag manufacturing. |
Applications

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-DBB | No on-chip capacitor; requires external 250–330 pF tuning cap; identical FDX-A/B support and 128-bit EEPROM. | Suitable where board-level capacitor placement is preferred over die-integrated capacitance; higher BOM count but greater tuning flexibility. | Select ATA5577C-DBB when custom coil resonance adjustment is needed beyond 250 pF ±3% tolerance. |
| EM4102-TD | Read-only architecture; no EEPROM write capability; fixed 64-bit ID; no configuration byte or lock bits. | Limited to static ID applications; cannot support UID personalization or firmware-updatable credentials. | Choose EM4102-TD only for cost-sensitive, non-reprogrammable access tokens where ISO compliance is secondary to unit price. |
Compared with ATA5575M2250-DBB, ATA5577C-DBB offers matching programmability and protocol support but shifts capacitor responsibility to PCB layout, while EM4102-TD sacrifices reprogrammability and configurability for lower gate count and unit cost - making it unsuitable for traceable animal ID or secure credential use.

FAQ
What is the exact on-chip capacitor value for ATA5575M2250-DBB?
The ATA5575M2250-DBB integrates a factory-trimmed on-chip antenna capacitor of 250 pF ±3%, optimized for 134.2 kHz FDX-B operation. This value is confirmed in Section 9 (Electrical Characteristics) and Table 11.2 of the 9217F-RFID-12/14 datasheet and corresponds to the "250" suffix in the part number. It eliminates the need for external tuning capacitors in standard coil designs.
Does ATA5575M2250-DBB support both FDX-A and FDX-B modes?
Yes, ATA5575M2250-DBB supports both ISO/IEC 11785 FDX-A (RF/50 data rate) and FDX-B (RF/32 data rate) modes via configuration byte 16. Bit 7 selects modulation (Differential Biphase for FDX-B, FSK2 for FDX-A), and bit 8 sets ID length (128 bits for FDX-B, 64/96 bits for FDX-A). Default delivery state is pre-configured for FDX-B.
How is memory protection implemented in ATA5575M2250-DBB?
ATA5575M2250-DBB implements memory lock protection via bits 1–5 of configuration byte 16. Setting them to '01101b' permanently locks the entire 136-bit EEPROM, preventing further RF-field reprogramming. Once locked, the device enters regular-read mode and transmits programmed data - a critical feature for tamper-proof animal ID and secure credentials.
What package form does ATA5575M2250-DBB ship in?
ATA5575M2250-DBB ships as a bare die on 6-inch wafer foil with 25 µm gold bumps (package code DBB), per Microchip's ordering documentation. Die size is 0.966 mm × 0.402 mm, with mega pads measuring 200 µm × 400 µm. It is intended for direct coil bonding in implantable or encapsulated RFID tag assemblies.
Can ATA5575M2250-DBB be reprogrammed after initial programming?
Yes, ATA5575M2250-DBB supports full EEPROM reprogramming via RF-field commands (Write Byte, Direct Access) until its memory lock bits are set. Programming time is 5.6 ms per byte with built-in erase-verify-program-verify cycle. After lock-bit activation ('01101b'), reprogramming is permanently disabled - ensuring data integrity in deployed tags.
