Product details
Overview
ATA5577M2330C-DBN from Microchip Technology (formerly Atmel) is a contactless 125–134 kHz LF RFID read/write identification IC with 363-bit EEPROM, configurable ISO/IEC 11784/11785 compatibility, and on-chip trimmed antenna capacitor. It operates via single-coil power harvesting and load modulation, supporting Basic and Extended modes for access control, animal identification, and waste management systems.
For engineers reviewing the ATA5577M2330C-DBN datasheet, ATA5577M2330C-DBN pinout, ATA5577M2330C-DBN application, or ATA5577M2330C-DBN equivalent, key selection criteria include RF frequency range (100–150 kHz), EEPROM block structure (11 × 33-bit blocks with lock bits), coil interface tolerance, modulation options (Manchester, bi-phase, FSK, PSK, NRZ), and compatibility with T5557/ATA5567 command sets.
Technical Context
The ATA5577M2330C-DBN integrates an analog front end with rectifier, clock extractor, field-gap detector, and switchable load modulator between Coil 1 and Coil 2. Its HV generator enables EEPROM programming without external high-voltage sources, and the data-rate generator supports binary-programmable rates from RF/2 to RF/128 plus fixed Basic mode rates (RF/8 to RF/128).
Memory is organized into two pages: Page 0 (8 blocks) holds configuration and user data; Page 1 (4 blocks) contains traceability data (pre-programmed and locked by Microchip), option register (block 3), and reserved fields. Block 0 stores mode/configuration data not transmitted during standard reads, while block 7 of Page 0 may serve as a write-protection password.
Key Specifications

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 memory map and command set; lacks on-chip antenna capacitor and ISO/IEC 11784/11785 configuration bits. | Requires external capacitor tuning; limited to legacy T555x protocol ecosystems without ISO standard support. | Select when cost-sensitive designs prioritize compatibility with existing T5557 infrastructure and omit ISO compliance needs. |
| ATA5567 | Identical functional architecture and pinout; differs only in mask option (ATA5567M1 vs. ATA5577M2 die size and bonding pad layout). | Same use cases but requires revalidation if migrating from wire-bond (M1) to direct-coil-bond (M2) assembly process. | Select when migrating from ATA5567M1 and retaining identical die-level functionality with updated packaging for improved coil integration. |
Compared with T5557 and ATA5567, the ATA5577M2330C-DBN adds factory-trimmed capacitance and ISO/IEC 11784/11785 configurability-enabling drop-in upgrades in animal ID and access systems while reducing BOM count and tuning effort.

FAQ
What is the primary function of the ATA5577M2330C-DBN in an RFID system?
The ATA5577M2330C-DBN functions as a contactless read/write identification IC (IDIC®) that harvests power and communicates bidirectionally via a single LC coil. It stores 363 bits of EEPROM data, supports load modulation uplink and OOK-encoded downlink, and serves as the core transponder IC in passive 125–134 kHz RFID tags used in access control, animal ID, and waste management.
Does the ATA5577M2330C-DBN require external components for basic operation?
Yes - while the ATA5577M2330C-DBN integrates a trimmed 330 pF antenna capacitor, it still requires an external coil (inductor) to form the resonant LC tank. No external voltage regulator, clock source, or high-voltage programming circuitry is needed, as all are implemented on-die including the HV generator and POR circuit.
How does the ATA5577M2330C-DBN handle data security and write protection?
The ATA5577M2330C-DBN implements per-block write protection using dedicated lock bits - one per 33-bit block. Once a lock bit is set, the entire block (including the lock bit) becomes permanently read-only. Block 7 of Page 0 can be configured as a password location, and traceability blocks (Page 1, Blocks 1–2) are pre-locked by Microchip during manufacturing.
Is the ATA5577M2330C-DBN compatible with T5557-based reader systems?
Yes - the ATA5577M2330C-DBN is explicitly designed for compatibility with T5557 and ATA5567 systems. Its configuration register structure, command set, and Basic/Extended mode behavior match those devices, enabling seamless integration into existing T555x infrastructure without reader firmware changes.
What distinguishes the "M2330C-DBN" suffix in the ATA5577M2330C-DBN part number?
The "M2" denotes the 200 µm × 400 µm die size optimized for direct coil bonding; "330" specifies the nominal on-die capacitor value (330 pF); "C" indicates commercial temperature grade (–40°C to +85°C); and "DBN" identifies the bare-die packaging format with non-conductive passivation and bond pads compatible with flip-chip or thermosonic bonding.
