Product details
Overview
E5530H-232-S8 from Atmel is a passive, battery-free RFID transponder IC designed for low-frequency inductive coupling identification systems. It functions as an RF-powered IDIC™ (Inductive Data and Identification Circuit), featuring factory-laser-programmed 64-bit ROM, Manchester modulation at RF/32 bitrate, and operation across 100–450 kHz RF fields - deployed in animal tagging and access control readers.
For engineers reviewing the E5530H-232-S8 datasheet, E5530H-232-S8 pinout, E5530H-232-S8 application, or E5530H-232-S8 equivalent, key selection criteria include its SO8 package compatibility, fixed E6 header + 56-bit unique ID code, absence of external power requirement, and FDX-B compliance per ISO 11784/11785.
Technical Context
The E5530H-232-S8 operates as a closed-coupled, backscatter-modulated transponder: it draws power from an inductively coupled RF field (100–450 kHz), rectifies it on-chip via integrated bridge rectifier and Zener clamp, and transmits data by controlled damping of the coil current. Its logic block includes clock extraction, modulator, counter, and 128-bit PROM array with laser-fused 64-bit customer code.
All transmission parameters are hard-coded in factory laser ROM: Manchester modulation, RF/32 bitrate (e.g., 3.9 kbit/s at 125 kHz), 64-bit code length (E6 header + 56-bit serial number), no checksum, and single-side load modulation using p-channel transistors between VDD and coil terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 100–450 kHz RF carrier - defines usable reader coil design and magnetic coupling range |
| Modulation Scheme | Manchester - provides self-clocking, DC-balanced backscatter signal for robust demodulation |
| Bitrate | RF/32 - e.g., 3.9 kbit/s at 125 kHz; sets timing resolution and maximum read distance under field strength constraints |
| Code Length | 64 bits (8-bit E6 header + 56-bit unique ID) - enables globally unique identification without checksum overhead |
| Supply Method | Inductive RF powering only - zero-battery operation; internal rectifier + Zener clamp protect against overvoltage up to 10 V |
| Temperature Range | −40°C to +125°C - supports deployment in automotive under-hood, livestock, and industrial environments |
| Package | SO8 - surface-mountable housing with dedicated Coil1 (Pin 1) and Coil2 (Pin 8); Pins 2–7 unconnected |
Pinout & Package
SO8 package with 15-mil thickness; Pins 2–7 are open and not electrically connected. Power and communication occur exclusively through the two coil terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Coil2) | RF coil terminal 2 | Completes inductive loop with Pin 8; carries damped RF current during backscatter transmission |
| Pin 8 (Coil1) | RF coil terminal 1 | Primary connection to reader coil; supplies harvested power and receives carrier signal |
Key Features
| Feature | Design Value |
|---|---|
| On-chip rectifier & Zener clamp | Enables direct RF-to-DC conversion and protects against coil-induced overvoltage up to 10 V |
| Factory laser-programmed ROM | Permanently stores 64-bit unique ID with fixed E6 header - eliminates post-manufacture programming infrastructure |
| Manchester modulation (RF/32) | Ensures reliable bit synchronization and noise immunity without external clock line or battery |
| FDX-B compatibility | Fulfills ISO 11784/11785 low-frequency animal identification standard for global regulatory acceptance |
| −40°C to +125°C operation | Validated performance across extreme ambient conditions - suitable for embedded tags in harsh mechanical environments |
Applications
| Animal Identification Tags | Access Control Badges |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TK5551-PP | Same Atmel silicon platform; supports same modulation/bitrate options but delivered as bare die (DIT) or wafer (DOW), not SO8 packaged | Requires custom antenna bonding and encapsulation - unsuitable for drop-in SO8 board replacement | Select TK5551-PP only for high-volume OEMs building proprietary tag assemblies with wire-bonding capability |
| EM4102 | Fixed 128-bit code, Biphase modulation, RF/64 bitrate; no laser-programmable header; different coil drive architecture | Lacks ISO 11784/11785 FDX-B compliance; limited to legacy access systems without animal ID requirements | Choose EM4102 only when retrofitting existing 125 kHz readers that do not support Manchester or E6-header protocols |
Compared with TK5551-PP and EM4102, the E5530H-232-S8 uniquely delivers factory-configured ISO-compliant Manchester encoding in a ready-to-mount SO8 package - eliminating assembly complexity while ensuring regulatory alignment for animal and secure access use cases.

FAQ
What is the exact modulation and bitrate configured in the E5530H-232-S8?
The E5530H-232-S8 is factory programmed with Manchester modulation and RF/32 bitrate - meaning, for a 125 kHz reader field, it transmits at 3.9 kbit/s. This configuration is permanently fused in laser ROM and cannot be altered in the field. The E5530H-232-S8 uses this setting to ensure interoperability with ISO 11785-compliant readers.
Does the E5530H-232-S8 require an external power source or battery?
No, the E5530H-232-S8 is fully passive and derives all operating power from the inductively coupled RF field (100–450 kHz). Its on-chip bridge rectifier, smoothing capacitor, and Zener clamp enable autonomous operation without batteries, capacitors, or external regulators - a core design feature of the E5530H-232-S8.
What does the "232" in E5530H-232-S8 signify?
The "232" is Atmel's customer-specific configuration code indicating Manchester modulation, RF/32 bitrate, 64-bit code length, E6 header, and no checksum - pre-programmed at wafer sort. This identifier distinguishes the E5530H-232-S8 from other variants like E5530H-111-S8 (FSK, RF/40, 128-bit), and is essential for ordering correct functional behavior.
Can the E5530H-232-S8 be used in metal-embedded applications?
Direct embedding in metal severely attenuates the magnetic field and degrades coupling - the E5530H-232-S8 will fail to power up or respond. Successful deployment requires air gaps, ferrite shielding, or plastic/mounting spacers. The E5530H-232-S8 datasheet explicitly warns against metal proximity to maintain reading distance and reliability.
What are the absolute maximum ratings for coil voltage and current on the E5530H-232-S8?
The E5530H-232-S8 has an absolute maximum coil current of 10 mA per terminal (Coil1 and Coil2), and a clamp voltage of 6.7–10 V at 4 mA. Exceeding these limits risks permanent damage. These ratings are validated under free-air conditions for ≤1 second - critical for designing reader driver stages that interface with the E5530H-232-S8.
