Flash memory with advanced security features for vehicle environments

6 November 2002 DSP, Micros & Memory

AMD is sampling what it claims is the industry's fastest Flash memory device designed to operate in demanding, high-temperature automotive environments. The Am29BDD160, a 16 Mb device, is designed to meet stringent demands for performance and reliability and is highly suited for applications in advanced automotive systems, including power-train management, high-end engine control modules, and anti-lock brake systems (ABS).

The device also delivers up to 33% faster access and up to 65% more data throughput than industry standard devices, according to the manufacturer. It is also the industry's only 66 MHz device that can function over a temperature range of -40 to +145°C. Enabling an automotive 'black box' data recovery type functionality, the device also features AMD's award-winning Simultaneous Read/Write architecture, which allows the system to read and program data at the same time without any latency.

AMD says that the new Flash memory device features 'Advanced Sector Protection Architecture'. This helps protect customers' valuable engine code and data against hackers who could seriously compromise the safety and performance of an automobile. The architecture includes the option of using a 64-bit password to defend any or all engine-control codes and data against unauthorised modification.
