Product details
Overview
TK5530HM-232-PP from Atmel is a complete 125 kHz read-only RFID transponder in plastic cube form, integrating the e5530 IDIC, tuned LC antenna (3.95 mH coil + capacitor), and factory-programmed 64-bit Manchester-encoded identification code with E6 header. It operates across –40°C to +85°C and delivers reliable modulation response at ≥18 A/m field strength at 25°C for car immobilizer authentication.
For engineers reviewing the TK5530HM-232-PP datasheet, TK5530HM-232-PP pinout, TK5530HM-232-PP application, or TK5530HM-232-PP equivalent, key selection criteria include resonant frequency tolerance (121.4–129.2 kHz), magnetic field sensitivity (17–30 A/m across temperature), modulation voltage range (4.0–8.0 V at 20–100 A/m), 125 kHz carrier compatibility, and plastic-cube mechanical integration for embedded access control systems.
Technical Context
The TK5530HM-232-PP implements passive inductive coupling: power and clock are extracted from a 125 kHz RF field via its integrated ferrite-core coil and tuning capacitor, enabling zero-battery operation. Its e5530 IC uses AM modulation with internal load damping to backscatter data serially.
It supports Manchester encoding at RF/32 bitrate and stores a fixed 64-bit ID with E6 header-no checksum-laser-programmed into PROM. The transponder's resonance stability (±0.8% over –40°C to +85°C) and H-DV curve-defined modulation depth ensure interoperability with U2270B-based readers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Carrier Frequency | 125 kHz nominal; 121.4–129.2 kHz typical resonance ensures reliable coupling with standard low-frequency reader antennas. |
| Memory Size & Type | 64-bit laser-programmed ROM; fixed E6 header + unique ID enables deterministic, tamper-resistant identification without reprogramming. |
| Encoding & Bitrate | Manchester; RF/32 (≈3.9 kbps at 125 kHz); provides self-clocking, DC-balanced transmission compatible with U2270B demodulation. |
| Operating Field Strength | 18 A/m min at 25°C; 30 A/m at –40°C; defines minimum reader field required for guaranteed activation in cold environments. |
| Modulation Voltage Range | 4.0–8.0 V DV at 20–100 A/m; quantifies usable backscatter signal amplitude for robust detection margin in noisy automotive settings. |
| Temperature Range | –40°C to +85°C operating; validated for under-hood and door-handle mounting in vehicle immobilizer and access systems. |
| Resonance Q-Factor | QLC ≥13; ensures sufficient selectivity to reject adjacent 134.2 kHz systems while maintaining adequate bandwidth for Manchester pulse edges. |
Pinout & Package
TK5530HM-232-PP is a fully encapsulated passive transponder in a plastic cube package (dimensions per Atmel doc 4683A–RFID–02/03); it has no external pins or terminals - power, clock, and data are coupled wirelessly via its integrated LC antenna.
Key Features
| Feature | Design Value |
|---|---|
| Integrated LC Antenna | Ferrite-core coil (3.95 mH) + capacitor tuned to 125 kHz enables drop-in deployment without external antenna design or tuning. |
| Laser-Programmed ROM | Factory-set 64-bit ID with E6 header ensures unalterable, traceable identity - critical for anti-cloning in automotive immobilizers. |
| Wide-Temperature Resonance Stability | Resonance stays within 120.0–131.0 kHz from –40°C to +85°C, maintaining link budget across full automotive thermal range. |
| AM Backscatter Modulation | Damping-based data transmission requires no active RF transmitter - eliminates battery, PCB traces, and RF shielding complexity. |
| Standardized Interface Compatibility | Designed for seamless interoperability with Atmel U2270B reader ICs and compliant base stations using 125 kHz inductive coupling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive 125 kHz RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TK5550F-PP | Same e5530 core but pre-programmed with rolling-code option; supports 64/128-bit variable coding schemes. | Used where dynamic ID rotation is required (e.g., high-security access), unlike TK5530HM-232-PP's fixed ID. | Select TK5550F-PP only if cryptographic agility is needed; TK5530HM-232-PP is optimal for cost-sensitive, static-ID use cases. |
| EM4100 (from EM Microelectronic) | 125 kHz read-only transponder with 64-bit Manchester output; no integrated coil - requires external antenna winding. | Demands custom coil design and tuning; lacks TK5530HM-232-PP's plug-and-play plastic cube integration. | Choose EM4100 only when board-level antenna optimization is prioritized over mechanical simplicity and time-to-market. |
Compared with TK5550F-PP and EM4100, TK5530HM-232-PP uniquely combines factory-fixed 64-bit Manchester ID, integrated tuned antenna, and automotive-grade temperature resilience - eliminating coil design, programming setup, and firmware updates required by alternatives.

FAQ
What is the memory configuration of TK5530HM-232-PP?
The TK5530HM-232-PP contains a 64-bit laser-programmed ROM with a fixed E6 header and unique ID code. No checksum is implemented. This configuration is factory-set and immutable - ensuring consistent, tamper-resistant identification for each unit shipped. The e5530 IC inside TK5530HM-232-PP does not support reprogramming or user-write operations.
Does TK5530HM-232-PP require an external power source?
No, TK5530HM-232-PP is entirely passive: it draws power and clock signal inductively from a 125 kHz RF field generated by a compatible reader (e.g., U2270B). Its integrated ferrite-core coil and tuning capacitor form a resonant LC circuit that enables energy harvesting and backscatter modulation - eliminating batteries, wiring, or PCB power routing.
What is the maximum operational read distance for TK5530HM-232-PP?
Maximum read distance depends on reader design, coil geometry, and field strength - not the TK5530HM-232-PP alone. With optimized U2270B-based readers generating ≥30 A/m fields, distances of 10 cm or more are achievable. On standard demo boards, typical range is 0–5 cm. Real-world performance must be validated in the final mechanical integration, as housing materials and orientation affect coupling efficiency.
Is TK5530HM-232-PP compatible with ISO/IEC 11784 or 11785 standards?
No, TK5530HM-232-PP is not compliant with ISO/IEC 11784 or 11785. It implements a proprietary Atmel protocol using Manchester encoding at RF/32 bitrate and fixed 64-bit structure. It is intended for proprietary systems like automotive immobilizers and private access control - not animal identification or open-standard livestock tracking.
Can TK5530HM-232-PP operate reliably at low temperatures?
Yes, TK5530HM-232-PP is rated for operation from –40°C to +85°C. Its resonance frequency remains within 120.0–131.0 kHz across this range, and minimum required field strength increases only moderately - to 30 A/m at –40°C - ensuring functional reliability in cold-start vehicle environments and outdoor access points.
