ATA5580 125kHz Transponder with Open Immobilizer Software Stack and AES-128 Encryption DATASHEET ● AES-128 crypto transponder in plastic brick package ● Includes coil and capacitor for tuned circuit antenna ● Radio frequency fRF = 125kHz ● Contactless power supply ● Contactless bidirectional data communication interface ● High-performance AES-128 encryption hardware unit ● open immobilizer stack ● 2K EEPROM for secret key storage, field user data and configuration data ● Error correction code support for NVM ● 32-bit unique ID ● Multiple configuration registers ● Modulation/coding Biphase, Manchester, QPLM ● Configurable baud rate ● to +85°C operation temperature ● LGA-like brick package 9254E-RKE-08/14 The ATA5580 is a smart transponder module with an AES-128 encryption unit, customer EEPROM, a 125kHz LF front end and an LF ferrite antenna for wireless power supply and communication. All components are built up in a single pinless transponder package. The IC contains the highly configurable Atmel open immobilizer software stack. Module Schematic The Atmel ATA5580 transponder contains an ultra-low-power transponder IC with an AES-128 engine, an LF Antenna resonant circuit and a buffer capacitor. Functional Description Atmel ATA5580 is designed for automotive immobilization applications in remote keyless entry RKE keys. The Atmel ATA5580 micro module consists of an ultra-low-power IC with AES-128 encryption engine and immobilizer front end, an LF ferrite antenna and capacitors for the antenna and as supply buffer. The small LGA-like package of the Atmel ATA5580 contains all the components required for the transponder application. Because it is powered by a 125kHz LF field, the IC requires no battery supply. The communication with the chip is also implemented via an LF field. A base station can request data via an LF telegram and the transponder responds with data from its memory or with cipher data via a damping modulation from the LF field. The transponder function is defined by a special Atmel immobilizer stack. Figure Block Diagram ATA5580 LF Antenna ATA5580 IC C2 L1 ATA5580 [DATASHEET] Atmel Open Immobilizer Protocol Description Overview Protocol Flexibility The immobilizer protocol has been designed as a configurable software stack. For example, security levels, turn-around authentication time and authentication schemes are all configurable at run time while covering a wide range of car manufacturer requirements. Additionally, Atmel defined three default configurations respectively targeting fast, standard, and high security for which analysis of bit security strength vs. turn-around time was carried out. Obviously, flexibility for tuning the protocol stack to meet specific constraints is still a feature. Open Software Stack Rather than developing its own proprietary cryptographic functions, Atmel selected and implemented the 128-bit AES-128 global benchmark standard as its data encryption and decryption source. This open source standard is freely available to the public for use and scrutiny. Because of this it continues to be favored by industry experts over private and proprietary crypto algorithms. In addition to selecting an open source and public AES-128 crypto function, the firmware includes user-configurable options that enable the engineer to “build” an authentication protocol that meets user requirements. The complete documentation of the protocol configuration options are made publicly available. The encryption and configuration of the authentication protocol are open source and freely available to customers free of charge. Production-Ready Software Implementation Besides defining an open immobilizer protocol stack, Atmel chose to implement it in all car access devices with an embedded LF front end. This implementation complies with automotive grade development standards CMMI - Automotive Spice and is production-ready.
