Development tools   
Atmel Corporation, founded in 1984, is a worldwide leader in the design, manufacturing and marketing of advanced semiconductors, including microcontrollers, advanced logic, nonvolatile memory, mixed signal, sensors and RF integrated circuits. Atmel is one of the elite new companies capable of integrating dense nonvolatile memory, logic and analog functions on a single chip. Atmel chips are manufactured using the most advanced wafer processes, including BiCMOS, CMOS and Silicon Germanium (SiGe) technologies.

Processor Families
AT91CAP9S
AT91CAP9S, based on the ARM926EJ-S®, offers superior performance at clock rates of up to 200 MHz, a number of standard interfaces (USB Host and Device, Ethernet, CAN, LCD Controller,  Image Sensor Interface, etc.), high-performance peripherals including 8 10-bit ADC channels, and an MP Block of 500K gates. The secured alternative offers AES and Triple DES encryption blocks. These are connected via a parallel bus structure that, together with a distributed DMA architecture, delivers the extremely high internal data bandwidth that is required by deeply embedded networked applications. more
AT91CAP7S
AT91CAP7S, based on the ARM7TDMI® processor core, has a generous amount (160K bytes) of fast on-chip SRAM and a large MP Block of 450K ASIC gates (2-input NAND equivalents). A minimal number of ARM peripherals are instantiated in the fixed portion of the design to address low cost applications. Additionally, there is the flexibility to instantiate other peripherals in the MP
Block using IP available in Atmel´s vast library. more
