Atmel ARM AT91SAM9RL
The AT91SAM9RL 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 SAM9RL LinuxLink for development targeting all designs based on Atmel AT91SAM9RL processor and its derivatives. The AT91SAM9RL features provide functionality for applications that require an LCD display with touch screen such as smart control panels.
Processor derivatives enabled:
The Atmel SAM9RL 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 SAM9RL LinuxLink can also be used as a starting point for Linux development for designs derived from the AT91SAM9RL-EK Development Kit from Atmel.
Notes:
Complete peripheral support for Atmel AT91SAM9RL 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 AT91SAM9RL is an ARM9-based microcontroller focused on applications that support smart control panels. It is powered by an ARM926EJ-S core, achieving 210 MIPS at 190 MHz.
The AT91SAM9RL SOC provides features and functionality required for intelligent user interfaces. With its double-buffered LCD controller with virtual screen support the SOC enables high-resolution, flicker-free displays.
