4. Hardware Description
4.1. Mechanics
The Panel-Card uses rugged and inexpensive 0.1″ headers as bus connectors which
facilitate prototyping. The Panel-Card can such be placed even on a standard 0.1" pitch
breadboard.
The size of the Panel-Card's PCB and the location of its mounting holes is adapted to the
mechanics of standard 93x70mm LCDs, so the Panel-Card can easily be mounted in any
enclosure which is prepared for such LCDs.
The position of the connectors, the board outline and the active area of the display is
symmetrical in both x- and y-direction. This makes up for a simple, straight forward and
unequivocal relationship between these parts in order to achieve a replaceability and
upgradeability for different combinations of base boards, CPU cards, and displays.
4.2. AT91SAM9261 Processor Core
The AT91SAM9261 runs at 200 MHz with a memory bus frequency of 100 MHz.
Here are some of the most important features of the Panel-Card ARM926EJ-S core:
• 16 Kbyte Data Cache, 16 Kbyte Instruction Cache, Write Buffer
• 32 Bit Data Bus
• ARM v4 and v5 Memory Management Unit (MMU)
• ARM v5 32-bit Instruction Set, ARM Thumb 16-bit Instruction Set supported
• DSP Instruction Extensions
• ARM Jazelle
®
Technology for Java
®
Acceleration
• EmbeddedICE
™
Debug Communication Channel Support
Some of these features - like Jazelle - are currently not supported by the operating system
of the product.
4.3. Memory
The Panel-Card is equipped with 32-Bit CPU-bus which is not exported on the connectors
but only used internally.
4.3.1. NOR Flash
The Panel-Card is equipped with a 16 MB or 64 MB NOR flash with 100000 erase and
write cycles. It is organized in 128KB blocks. Customer specific adaptations are possible
