To fully exploit the SAM3U's high speed communications peripherals, the device is built around a high data-bandwidth architecture with a 5-layer bus matrix, 23 DMA channels and distributed on-chip memory including up to 52k Bytes of SRAM split in three blocks and up to 256k Bytes of Flash in two banks
At the "Arduino level" I doubt there would be much difference except the obvious speed and memory as you mentioned. If you wanted to delve a little deeper though there's a world of difference.______Rob
No one will be building standalone versions to be run on their breadboard or simple protoboard projects.
wondering what the differences are going to be, aside from the obvious speed, and memory ..
Maybe there will be a "mini" version soon? Maybe like the mbed, Netduino Mini, or MicropendousX?
The PIC32 used in the Digilent chipKIT Arduino offers a lot more performance than the SAM3U used in the Due.
with 128k being the "standard" on current pic32 boards I feel abit meh about this product
Arduino Due, a major breakthrough for Arduino because we're launching an Arduino board with a 32bit Cortex-M3 ARM processor on it. We're using the SAM3U processor from ATMEL running at 96MHz with 256Kb of Flash, 50Kb of Sram, 5 SPI buses, 2 I2C interfaces, 5 UARTS, 16 Analog Inputs at 12Bit resolution and much more.
Hey if you guys want to compare the PIC32 with ARM Cortex-M3, we should be comparing FLOPs and other benchmarks, not just pure clock speed and memory.
