Product details
Overview
ATA5577M2330C-DBQ from Microchip Technology is a contactless read/write LF RFID identification IC operating at 125 kHz or 134 kHz, using a single coil for both power harvesting and bidirectional communication via load modulation. It integrates 363-bit EEPROM (11 × 33-bit blocks), supports ISO/IEC 11784/11785 compatibility, and features programmable data rates (RF/2 to RF/128), multiple modulation schemes (Manchester, FSK, PSK, NRZ), and password-protected write access - deployed in animal identification tags and access control transponders.
For engineers reviewing the ATA5577M2330C-DBQ datasheet, ATA5577M2330C-DBQ pinout, ATA5577M2330C-DBQ application, or ATA5577M2330C-DBQ equivalent, this page delivers verified technical context, exact pin functions, real-world use-value per application, confirmed alternative parts with functional differences, and supply-chain support details specific to this pad-type-2 die variant.
Technical Context
The ATA5577M2330C-DBQ implements an analog front end with on-chip rectifier, clock extractor, field gap detector, and switchable resistive load between Coil 1 and Coil 2 for uplink transmission. Its controller loads configuration from EEPROM block 0 and AFE options from block 3 (page 1), supporting both Basic and Extended (X-mode) operation enabled by master key values 6 or 9.
Downlink decoding uses Pulse Interval Encoding (PIE) with OOK modulation; uplink employs load modulation with configurable damping. The HV generator enables EEPROM programming, while soft modulation switching and demodulation delay compensate for high-Q antenna timing imbalances - all managed via EEPROM-configurable registers including Mode, Option, and Configuration registers.

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 330 pF internal capacitor, identical Configuration register layout, and compatible PIE downlink protocol - but lacks OTP lock, soft modulation, and ISO/IEC 11784/11785 setup bits. | No factory-programmed traceability structure; limited AFE configurability reduces adaptability to harsh EMI environments. | Select T5557 only for legacy system drop-in replacement where extended features are unused and cost is primary constraint. |
| ATA5567 | Shares core architecture and pad-type-2 footprint, but offers only 264-bit EEPROM (8 × 33-bit blocks); no dedicated traceability blocks or ACL/MFC encoding in memory map. | Cannot meet ISO/IEC 15963-1 allocation class requirements; unsuitable for regulated animal ID deployments requiring E0h ACL prefix. | Choose ATA5567 for non-regulated industrial tagging where smaller memory and lower unit cost outweigh traceability compliance needs. |

FAQ
What is the difference between ATA5577M2330C-DBQ and ATA5577M1C variants?
The ATA5577M2330C-DBQ uses pad-type-2 (200 μm × 400 μm) for direct coil bonding and integrates a 330 pF ±3% on-chip capacitor, whereas ATA5577M1C uses pad-type-1 (100 μm × 100 μm) for wire bonding and includes a 250 pF ±3% capacitor. Both share identical EEPROM architecture, modulation capabilities, and command set - but capacitor value and pad geometry require separate antenna matching and assembly processes. The ATA5577M2330C-DBQ is optimized for high-volume, low-profile tag manufacturing.
Does ATA5577M2330C-DBQ support ISO/IEC 11784/11785 out of the box?
Yes - the ATA5577M2330C-DBQ supports ISO/IEC 11784/11785 compatibility through EEPROM-configurable modulation parameters and data formatting. Blocks 1 and 2 of page 1 contain factory-programmed traceability data with ACL = E0h and MFC = 15h, satisfying ISO/IEC 15963-1 and 7816-6 requirements. Configuration register bits enable Manchester encoding and fixed data rates required by the standard - no hardware change is needed.
How is password protection implemented in ATA5577M2330C-DBQ?
Password protection in ATA5577M2330C-DBQ is enforced via bit PWD = 1 in the Configuration register. When active, the first 32 bits after opcode '00' are compared against block 7 (password memory). A mismatch aborts programming and forces return to Regular-Read mode. MAXBLK must be set < 7 to prevent password exposure during readout. Each password attempt takes ~18 ms, making brute-force attacks impractical - critical for secure access fob applications.
Can ATA5577M2330C-DBQ operate with high-Q antennas?
Yes - the ATA5577M2330C-DBQ includes soft modulation switching and configurable demodulation delay to mitigate timing violations caused by high-Q antenna ringing. These features, controlled via the AFE Option register (block 3, page 1), adjust modulation transition smoothness and pulse alignment - enabling reliable operation with Q-factors >100, which is typical for precision wound or ferrite-core LF antennas used in medical or industrial readers.
What happens when the OTP bit is set with master key = 6 in ATA5577M2330C-DBQ?
When OTP = 1 and master key = 6 in ATA5577M2330C-DBQ, all EEPROM blocks become permanently write-locked - including lock bits themselves - and Extended mode remains enabled while Test mode access is denied. This creates true One-Time-Programmable behavior: no further configuration changes, password updates, or memory writes are possible after initial programming. It is used in regulatory animal ID tags to guarantee immutable identity and prevent tampering post-deployment.
