Product details
Overview
ATA5580M132-TSMW from Microchip Technology (formerly Atmel) is a fully integrated 125kHz contactless transponder module with AES-128 encryption engine, 2K EEPROM, LF ferrite antenna, and tuned resonant circuit - designed for automotive immobilizer authentication in RKE keys. It operates without battery, draws power from the LF field, supports Biphase/Manchester/QPLM modulation, and delivers a 32-bit unique ID and configurable bilateral/unilateral challenge-response authentication.
For engineers reviewing the ATA5580M132-TSMW datasheet, ATA5580M132-TSMW pinout, ATA5580M132-TSMW application, or ATA5580M132-TSMW equivalent, this page provides verified technical context, real-world timing behavior, memory partitioning details, LF physical layer compatibility, and selection guidance against comparable transponder modules used in production-grade vehicle access systems.
Technical Context
The ATA5580M132-TSMW implements a complete LF transponder subsystem in a single LGA-like brick package: ultra-low-power IC, embedded 125kHz ferrite antenna, and buffer capacitor form a self-contained resonant circuit. Its AES-128 hardware engine executes authenticated encryption directly on-chip, with secret keys stored in protected AP0 EEPROM regions and default key locked in page 2.
It supports FDX-compliant bidirectional communication via amplitude modulation: downlink uses OOK with BPLM/QPLM/DPS coding; uplink uses 50% modulation depth with configurable Manchester or Biphase encoding at ~3.906 kb/s. Initialization prioritizes immobilizer firmware execution from bootloader space, ensuring deterministic startup under LF field detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| fRF | 125 kHz - defines carrier frequency for LF field coupling and wireless power transfer |
| Encryption | AES-128 hardware engine - enables secure challenge-response authentication without software overhead |
| EEPROM | 2 Kbytes - partitioned into AP0 (user-configurable key/data storage) and locked page 2 (default key, UID, traceability) |
| Unique ID | 32-bit non-sequential serial number - factory-programmed at 0x0800–0x0803, accessible via Read UID command |
| Modulation | Biphase, Manchester, QPLM - selectable uplink/downlink coding schemes supporting interoperability with standard FDX base stations |
| Operating Temp | –40°C to +85°C - qualified for under-hood and key fob environments per automotive requirements |
| Power Source | Contactless LF field only - eliminates battery dependency and enables maintenance-free operation over lifetime |
Pinout & Package
LGA-like brick package (pinless, surface-mountable module); no external pins or terminals - all RF coupling, power harvesting, and data modulation occur through integrated ferrite antenna and internal resonant circuit.
Key Features
| Feature | Design Value |
|---|---|
| Atmel Open Immobilizer Stack | Firmware-configurable protocol supporting fast/standard/high-security modes - enables OEM-specific tuning of authentication time vs. bit-security strength |
| Error Correction Code (ECC) | Applied to NVM - ensures integrity of EEPROM-stored keys and configuration data across temperature and lifetime |
| Secret Key Redundancy | Two operational keys stored with dual copies in AP0 - automatic error correction during readout prevents authentication failure from single-bit corruption |
| LF Field Detection Header | Configurable Manchester-coded preamble - confirms reliable uplink/downlink channel establishment before authentication begins |
| Production-Ready Firmware | CMMI/Automotive SPICE-compliant implementation - shipped pre-verified for integration into certified car access systems |
Applications
| Remote Keyless Entry (RKE) Keys | Automotive Immobilizer Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP UCODE I2C | UHF (860–960 MHz) RFID IC with I2C interface - requires external antenna and power supply; no integrated LF front end or AES engine | Designed for inventory tracking or smart label use, not automotive immobilization | Select only if migrating to UHF-based access systems with host MCU handling crypto and protocol |
| Infineon SLI13 | 13.56 MHz HF transponder with 1K EEPROM and ISO/IEC 15693 compliance - lacks AES-128 hardware, LF power harvesting, or open immobilizer stack | Targeted at NFC-enabled keys or proximity cards, not 125kHz immobilizer protocols | Choose only for non-automotive, short-range identification where LF field immunity and battery-free operation are not required |
Compared with ATA5580M132-TSMW, UCODE I2C and SLI13 lack integrated 125kHz antenna, contactless power harvesting, and production-ready open immobilizer firmware - making them unsuitable drop-in replacements for automotive RKE/immobilizer use cases requiring FDX compliance and AES-128 authentication.

FAQ
What is the operating frequency and physical interface of the ATA5580M132-TSMW?
The ATA5580M132-TSMW operates exclusively at 125 kHz using a contactless LF magnetic field for both power delivery and bidirectional data communication. It contains an integrated ferrite antenna and resonant capacitor - no external RF components, connectors, or power supply are required. Communication occurs via amplitude modulation (OOK), with downlink supporting BPLM/QPLM/DPS coding and uplink supporting Manchester or Biphase encoding at ~3.906 kb/s.
Does the ATA5580M132-TSMW require a microcontroller or external host to function?
No - the ATA5580M132-TSMW is a self-contained transponder module with embedded immobilizer firmware, AES-128 hardware engine, and bootloader-managed flash memory. It executes authentication autonomously upon LF field detection and responds to base station commands (e.g., Read UID, Start Authentication) without any external processor. The Atmel open immobilizer stack runs natively on-chip.
How is secure key storage implemented in the ATA5580M132-TSMW?
The ATA5580M132-TSMW stores two operational 128-bit secret keys in AP0 section of its 2K EEPROM, each with two redundant copies for ECC-based error correction. A third fixed default key is permanently locked in page 2 (0x081B–0x082A) and used only during secure key transfer. All keys are inaccessible via LF commands - protecting against side-channel extraction during normal operation.
Is the ATA5580M132-TSMW compatible with standard FDX base stations?
Yes - the ATA5580M132-TSMW complies with FDX (Full Duplex) physical layer specifications. Its downlink OOK modulation and uplink 50% amplitude modulation meet ISO 11784/11785 requirements. It supports standard FDX command framing, CRC protection, and error signaling (1 kHz waveform), ensuring interoperability with third-party base stations including ATA5272 and other automotive-grade transceivers.
What is the role of the 32-bit unique ID in the ATA5580M132-TSMW?
The 32-bit unique ID in the ATA5580M132-TSMW is factory-programmed at EEPROM addresses 0x0800–0x0803 and serves as a non-sequential, immutable serial identifier for vehicle-level pairing and anti-cloning enforcement. It is accessed via the dedicated "Read UID" command (4-bit request + 1-byte header 0xFE + 4-byte payload), enabling rapid, low-overhead identification during base station interrogation sequences.
