Atmel ARM AT91SAM9263
The LinuxLink software distribution model enables the usage of the Atmel SAM9263 LinuxLink for development targeting all designs based on Atmel AT91SAM9263 processor. The AT91SAM9263 is an optimized host processor for applications with an LCD display.
Reference boards/OEM boards enabled:
The Atmel SAM9263 LinuxLink can also be used as a starting point for Linux development for designs derived from the AT91SAM9263-EK Evaluation Kit from Atmel.
Notes:
Complete peripheral support for Atmel AT91SAM9263 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 AT91SAM9263 is a complete system-on-chip built around the ARM926EJ-S ARM Thumb processor with an extended DSP instruction set and Jazelle Java accelerator. It achieves 210 MIPS at 190 MHz.
The processor's parallel bus architecture incorporating distributed DMA overcomes the bottlenecks that occur with conventional ARM9-based MCUs in graphically-interfaced, data-intensive applications such as networked medical monitoring equipment and GPS navigation systems.
On-chip peripherals include a camera interface, TFT/STN LCD controller, a 6-channel audio front-end interface (AC97), I2S and a 2D graphics co-processor that off-loads line draw, block transfer, polygon fill, and clipping functions from the CPU.
Networking peripherals include a 12 Mbps USB host and device and a 10/100 Ethernet MAC. There are also four USARTs, two 50 Mbps serial parallel interfaces (SPI), CompactFlash, SDIO (MCI) and a two-wire interface (TWI).
The AT91SAM9263 also benefits from the integration of a wide range of debug features including JTAG-ICE, a dedicated UART debug channel (DBGU) and an embedded real-time trace. This enables the development and debug of all applications, especially those with real-time requirements.
