XMEGA highlights
• picoPower™ technology for ultra low power consumption
• True 1.6 volt operation and CPU speeds up to 32 MHz
• Event System and DMA controller
• High speed, high resolution 12-bit ADC and DAC
• Crypto engine, Timers/Counters and fast communication
interfaces
• Accurate and fexible Clock System with automatic clock failure protection
All AVR devices from the smallest tinyAVR to the largest XMEGA uses the same CPU. They differ only in features, pin count and memory size. This enable AVR to cover the complete 8- and 16-bit market with one
single, compatible product family.

ARM MCU for power-constrained applications
|
| |
 |
|
The AT91SAM9G20 is based on the ARM926EJ-S processor, with a clock speed of 400MHz. It features 32K byte instruction and 32K byte data cache memories, two 16K-byte blocks of SRAM and 64K bytes of ROM with single cycle access at maximum processor or bus speed, together with an external bus interface with controllers for SDRAM and static memories including NAND Flash and CompactFlash. Its extensive peripheral set includes USB Full Speed Host and Device interfaces, a 10/100 Base T Ethernet MAC, Image Sensor Interface, Multimedia Card Interface (MCI), Synchronous Serial Controllers (SSC), USARTs, Master/Slave Serial Peripheral Interfaces (SPI), two three-channel 16-bit Timer Counters (TC), a Two Wire Interface (TWI) and four-channel 10-bit ADC. Three 32-bit Parallel I/O Controllers multiplex the pins to/from these peripherals in order to reduce the device pin count, and peripheral DMA channels maximize the data throughput between these interfaces and the on- and off-chip memories.
