Its flash architecture keeps the part's 2-kbyte flash boot memory separate from its program memory for better security during ISP operations. The programmer can modify the flash boot memory only in parallel mode, thereby avoiding any mishandling of the boot memory contents during ISP operations. Philippe Malecha, marketing director for customer and application-specific products at Atmel's Wireless and Microcontrollers Division, noted that each of the device's four message objects can be used in 2.0A and 2.0B nodes in existing CAN networks. Electromagnetic interference is reduced as a result, according to Atmel. Automotive temperature-range versions are currently under qualification.
