1. Description
The Atmel
®
AT91 Customizable Microcontroller Processor (AT91CAP) concept allows
customization of ARM7
™
or ARM9
™
platforms by adding specific peripherals and/or
digital logic into a Metal Programmable Block (MPBlock). The AT91CAP is separated
into two different areas:
1. AT91CAP hard part: A fixed area containing the ARM
®
processor, the ARM
system, the internal memories and several peripherals described in the
AT91CAP datasheet.
2. MPBlock part: Metal Programmable area dedicated to customization and
using only the metal levels of the technology.
The User Guide shows the capabilities for customization of the
AT91CAP9S500A/AT91CAP9S250A based on a concrete example.
The customization example includes the following objects:
• An AHB2APB Bridge creating a dedicated APB bus inside the MPBlock
• An AHB Peripheral DMA controller
• An APB Debug Unit (UART) connected to the Peripheral DMA Controller
• An Internal RAM Controller using the dedicated MPBlock RAM blocks
The User Guide first describes the AT91CAP9S500A/AT91CAP9S250A database in
terms of directories and logical design structure. It then guides the user through the
complete AT91CAP9S500A/AT91CAP9S250A customization flow using the given
example.
