Product details
Overview
ATA5575M233A-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, featuring 128-bit user EEPROM (16 bytes), 8-bit configuration memory, on-chip 330 pF ±3% antenna capacitor, and ISO/IEC 11784/11785 FDX-B compliance - deployed in animal ID tags and industrial traceability systems.
For engineers reviewing the ATA5575M233A-DBB datasheet, ATA5575M233A-DBB pinout, ATA5575M233A-DBB application, or ATA5575M233A-DBB equivalent, this page delivers verified technical context, exact memory mapping, modulation modes (Differential Biphase RF/32, FSK2 RF/50), lock-bit behavior, programming timing (5.6 ms), and gold-bump die-level packaging for direct coil bonding.
Technical Context
The ATA5575M233A-DBB 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 byte-wise EEPROM programming using pulse-interval-encoded downlink commands at 125 kHz carrier frequency.
It supports two configurable data rates: RF/32 (FDX-B mode, 3.9 kHz) and RF/50 (FDX-A mode, 2.5 kHz), with modulation schemes including Differential Biphase and FSK2. Configuration resides in EEPROM byte 16, controlling ID length (64/96/128 bits), modulation type, and lock-bit state (00001b = reprogrammable; 01101b = fully locked).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EM4102 | Read-only architecture; no EEPROM write capability; fixed 64-bit ID; no on-chip capacitor | Suitable only for pre-programmed, non-reconfigurable tags; lacks FDX-B framing and lock-bit security | Select when cost-sensitive, static-ID use cases eliminate need for field programming or ISO compliance |
| TKS4001 | 125 kHz only; 128-bit OTP memory (one-time programmable); no lock-bit flexibility; 250 pF on-chip cap | Supports FDX-B but requires permanent programming at wafer test; no reprogramming or dummy-mode fallback | Choose for high-volume, factory-programmed deployments where post-assembly update is unnecessary |
Compared with EM4102 and TKS4001, the ATA5575M233A-DBB uniquely combines field-reprogrammable EEPROM, ISO-compliant FDX-B telegram generation, configurable lock bits, and integrated 330 pF capacitance - making it the only option supporting secure, updatable, and standards-certified LF RFID tagging across animal, industrial, and medical domains.

FAQ
What is the exact package type and mounting method for ATA5575M233A-DBB?
ATA5575M233A-DBB is supplied as a bare die on 6-inch wafer foil with ring mount and 25 µm gold bumps (package code DBB). It features 200 µm × 400 µm mega pads for direct wire bonding or flip-chip attachment to antenna coils - not a packaged IC with leads or solder balls.
Does ATA5575M233A-DBB support both FDX-A and FDX-B modes, and how is the mode selected?
Yes, ATA5575M233A-DBB supports both FDX-A (RF/50, FSK2) and FDX-B (RF/32, Differential Biphase) modes. Mode selection is controlled by bits 7 and 8 in EEPROM byte 16: bit 8 = 1 selects 128-bit ID (FDX-B), bit 7 = 1 selects FSK2 (FDX-A). Default delivery state is FDX-B (0x09).
What is the function of byte 16 in the ATA5575M233A-DBB EEPROM, and how do lock bits affect operation?
Byte 16 is the configuration register governing ID length, modulation type, and memory lock state. Lock bits (bits 1–5) determine behavior: 00000b outputs dummy data; 00001b enables regular read of programmed data; 01101b locks all memory permanently. Once set to 01101b, no further writes are possible.
How does the on-chip 330 pF capacitor in ATA5575M233A-DBB improve system design?
The integrated 330 pF ±3% capacitor eliminates the need for an external resonant capacitor in the LC tank circuit. This reduces BOM count, improves layout tolerance to coil parasitics, enhances Q-factor stability across temperature, and simplifies antenna matching - especially critical for miniaturized or implantable tags.
What is the programming time and verification process for ATA5575M233A-DBB EEPROM writes?
Each byte write takes 5.6 ms and includes four verified steps: erase, erase verification (all bits = 0), program, and program verification (target bits = 1). The IC automatically exits to byte-read mode upon completion, transmitting the newly written byte - enabling real-time confirmation without external polling.
