Flash cards and USB Flash Devices (UFD) are key removable storage elements in consumer devices today, whether it be smartphones or digital cameras. Consumers are looking for cost effective solutions at the right performance point. Applications such as High density (HD) video and photography are driving a transition to faster, serial interfaces such as the migration from USB 2.0 to USB 3.0 which is a 10x performance increase. A majority of the embedded controllers for these applications are based on low performance 8-bit cores that are now running out of steam. Flash card and UFD OEMs are demanding higher performing controllers and are driving towards 32-bit processor cores.

Flash cards and USB Flash Devices (UFD) are key removable storage elements in consumer devices today, whether it is smartphones or digital cameras. Consumers are looking for cost effective solutions at the right performance point. Applications such as High density (HD) video and photography are driving a transition to faster, serial interfaces such as the migration from USB 2.0 to USB 3.0 that is a 10x performance increase. A majority of the embedded controllers for these applications are based on low performance 8-bit cores that are now running out of steam. Flash card and UFD OEMs are demanding higher performing controllers and are driving towards 32-bit processor cores.
Flash cards and UFDs are a very cost sensitive application where performance has not been of great value. Consumer thirst for accessing video and audio content instantly is driving that application space to transition from slower parallel interfaces to high speed serial interfaces with higher and higher memory densities, all while lowering cost. As a result, the processing power required is driving this application toward 32-bit architectures.
Flash card and USB Flash Device OEMs have always been concerned with cost, not just silicon but system as well. ARM Cortex-M series processors deliver 32-bit processor performance in an 8-bit processor footprint.
The ARM® architecture has the advantage of better memory performance and density than alternative architectures leading to lower system costs.
