ICs for Car Access Applications ICs for Car Access Applications Atmel® has about 30 years of design expertise in automotive products. The company launched the first dedicated transmitter for remote keyless entry (RKE) applications in 1997. For car access applications, Atmel provides a wide range of innovative ICs. Customers can create their own designs using the low-power Atmel T575xC/ATA575xC radio transmitter IC family, a dedicated Atmel ATA581xC/2xC transceiver family, an Atmel ATA572xC/ATA574xC receiver IC family, and the Atmel AVR® microcontroller-based ATA577xC RF transmitter family. The Atmel car access portfolio includes all devices needed to design a complete solution. Uni-directional RF link for the keyless entry function to open or lock car doors. The immobilizer system is built with a bi-directional LF link operating with the AUT64 crypto algorithm. Bi-directional RF link for RKE functions as well as for the extremely secure duplex RF link in a Passive Entry Go (PEG) system. The LF link is used for the wake-up channel in a PEG system as well as for the immobilizer function to start the RF communication. 2 © 2013 / www.atmel.com ICs for Car Access Application Transmitter ICs Atmel Part Number Frequency Range (MHz) System Suitability 868 to 928 315 433 RKE 315 433 RKE, PEG, Remote Start Frequency Range (MHz) System Suitability 433.868 315 312.5-317.5 312.5-317.5 RKE, PEG, Remote Start 433.92 RKE, PEG, Remote Start Frequency Range (MHz) System Suitability ATA5723C ATA5724C ATA5728C UHF Receiver ICs • Shortest Bill of Material Due to Highest Integration Level • 3 Pin-compatible Frequency Versions • RSSI Output • Low-cost 13MHz Crystal Usage Possible for all three Versions • Lowest Current Consumption Due to Polling Feature • ASK/FSK Modulation 315 433 686 RKE, PEG, Remote Start ATA5745C ATA5746C UHF Receiver ICs for Car Access and TPMS • Extremely Fast Switching Rate Between RKE and TPMS Signals Typically <1ms • Complete Functionality to Design a TPMS System (e.g., RSSI) • High System Sensitivity and Selectivity Achievable with a Low Number of External Components • Polling Mode and Bit Check Carried Out by External Firmware 433 315 RKE, PEG, Remote Start ATA5780N • Highly Sensitive UHF ASK/FSK Receiver 310–318 418–477 836–928 RKE, Combi Key Description ATA5771C ATA5773C ATA5774C Atmel AVR Microcontroller-based RF Transmitter Family • System-in-Package (SiP) Solutions Including AVR Microcontroller ATtiny44V and the RF Transmitter Family T5750C/53C/54C • Ideal for High-volume, Uni-directional RF RKE Keys Fobs • Small-outline, Tiny QFN24 Packages 5mm x 5mm Enable Design of Extremely Small, Cost-efficient Key Fobs ATA5749C Low-power RF Transmitter IC • Fully Integrated Fractional–N PLL • –0.5dBm to 12.5dBm Scalable Using Output Power Programming • Active Current Consumption 7.3mA at 5.5dBm • Polling Mode and Bit Check Carried Out by External Firmware Transceiver ICs Atmel Part Number Description ATA5811C ATA5812C ATA5823C ATA5824C • • • • Industry’s Lowest Current Consumption and Smallest Size High Sensitivity and High Data Rate for Quick Reaction Time Adjustable Output Power up to +10dBm for Long-distance Operation High Selectivity, High Blocking, and Low Intermodulation Due to the Low-IF Architecture ATA5831 ATA5832 ATA5833 MCU-Based RF Transceiver ICs • Industry’s Lowest Power Consumption • High Sensitivity and High Output Power (< 14.5dBm Typ.) for Long-distance Operation • Can Be Configured via EEPROM Receiver ICs Atmel Part Number Description ICs for Car Access Applications 3 Antenna Driver ICs Atmel Part Number ATA5279C Description Six-fold Antenna Driver IC • Enables Smaller and Less Expensive Designs • Increased Reliability • Superior EMC Behavior • Diagnostic Features, IC Protects Itself and System from Damage Frequency Range (kHz) System Suitability 125 PEG Immobilizer ICs Atmel Part Number TK5561 ATA5580 4 Frequency Range (kHz) System Suitability Read/Write Transponder • Integrated LC Tank and Built-in Proprietary Crypto Algorithm • Low-power/Low-voltage CMOS • 9 x 32-bit EEPROM 125 Immobilizer AES-128 Immobilizer Transponder • Read/Write Transponder for High Security Applications • AES-128 Hardware Encryption • 2Kbyte EEPROM • Atmel Open Immobilizer Protocol 125 Description Immobilizer © 2013 / www.atmel.com ICs for Car Access Application Car Access Key System Devices Atmel Part Number ATA5790N Description Atmel AVR-based Passive Entry Go System Device with 3D Wake-up and Immobilizer Functionality Open Standard Immobilizer Protocol Based on High-security AES-128 ATA5791 Embedded AVR Microcontroller Including RF Transmitter and Complete LF Functionality ATA5795C Atmel AVR-based Transmitter IC with Immobilizer Functionality ICs for Car Access Applications System Suitability PEG, Immobilizer Passive Entry/ Passive Start RKE, Immobilizer 5 Car Access Components -
