ATSAM3U-EK

ATSAM3U-EK is an evaluation kit which allows designers quickly evaluate and develop code for applications running on Atmel SAM3U4E microcontrollers. The SAM3U4E is a flash microcontroller based on high performance 32bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 96MHz and features two 128KB of dual bank flash and 52KB of SRAM. The peripheral set includes a HS USB device and Phy at 480Mbps, HS multimedia card interface for SDIO/SD/MMC, a 16bit external bus interface supporting NAND flash, three USARTs, two TWIs, four SPIs, I2S, four PWM timers, three 16bit timers, RTC and eight 12bit and eight 10bit ADCs. The architecture sustains high speed data transfers, with multi layer bus matrix, multiple SRAM banks, PDC and DMA support parallel tasks. The ATSAM3U-EK board is equipped with a three axis accelerometer MMA7341. Basically, it is an acceleration to analogue voltage converter. Converted data on corresponding directions are read by three SAM3U4E 12bit ADC channels.
