ATA5795C is a smart remote keyless entry (RKE) device that includes an embedded ultra-low-power AVR 8-bit microcontroller, a fractional-N RF transmitter and an LF immobilizer interface in a single QFN32 package. The device has an integrated AES-128 cryptography hardware engine, which is accessible by both the immobilizer and the RKE unit. The immobilizer interface can run in contactless mode, allowing energy supply and data transmission via the LF link. The ATA5795C is designed for automotive applications that necessitate both immobilization and remote keyless entry functions in one single key. It conforms to requirements of extremely low power consumption and provides all the necessary circuitry for the entire application.
- System solution for immobilizer and remote keyless entry functionality
- Optional integrated open source immobilizer software stack supports automotive immobilizer applications (CMMI certified)
- Integrated ultra-low power flash AVR® (8-bit) microcontroller
- 2112-byte EEPROM
- 32-bit unique device identification number
- Available in small 5×5 QFN32 pin package? LF contactless transponder operation in passive and active modes? Fully integrated fractional-N PLL, VCO and loop filter covering 315MHz and 433MHz (software programmable)? 8Kbyte flash program memory (including 2KB of immobilizer software stack)
