page 7 AVR UC3 FLASH MicrocontRollers Everywhere You Are® System Performance For embedded systems, system performance is much more than a good MIPS number. It is important to have powerful, fast peripherals and an energy-efficient memory system that allows the application to run effortlessly with minimal power consumption. Single Cycle SRAM Fast SRAM access is critical to achieving the necessary computing performance. The UC3 CPU has a single-cycle access to the SRAM embedded in the CPU itself.
www.atmel.com page 8 Peripheral DMA Controller The Atmel Peripheral DMA controller sets a new standard for data transfer efficiency. If the Peripheral DMA controller is not enabled, the maximum usable transfer rate on the SPI module would be approximately 1 MBit/s, occupying the CPU with more than 50% load just moving data around.
page 9 AVR UC3 FLASH MicrocontRollers 07 Everywhere You Are® Security The 32-bit AVR UC3L provides mechanisms to protect the system from hacker modification, flash software theft and runaway code. Secure CPU State CPU resources and sections of code/data memory can be reserved for proprietary software IP or critical sections of code/data. A special API is used to access these resources from the rest of the code.
