Atmel ARM AT91CAP9
The AT91CAP9 system-on-chip is a member of the Atmel’s AT91SAM9 family of processors. The LinuxLink software distribution model enables the usage of the Atmel CAP9 LinuxLink for development targeting all designs based on Atmel AT91CAP9 processor and its derivatives. The AT91CAP9 features provide functionality for wide range of applications including those that require an LCD display with touch screen. The CAP9 processor is accompanied by external Field Programmable Gate Array (FPGA) allowing users to extend processor capabilities.
Processor derivatives enabled:
The Atmel CAP9 LinuxLink can be used as a starting point for Linux development for designs based on any of the processors from the ARM9E family.
Reference boards/OEM boards enabled:
The Atmel CAP9 LinuxLink can also be used as a starting point for Linux development for designs derived from the AT91CAP9-DK Development Kit from Atmel.
Notes:
Complete peripheral support for Atmel AT91CAP9 derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
The AT91CAP9 is an ARM9-based microcontroller that combined with an external FPGA enables creation of customized processors that match your specific project requirements. Thanks to this high flexibility CAP9 technology can be used to build cost effective system for various markets. The fixed core processor is powered by an ARM926EJ-S core, achieving 220 MIPS at 200 MHz. The AT91CAP9 SOC provides features and functionality most commonly used in embedded systems.
