The AT91CAP7E embeds 160-Kbytes of high-speed SRAM configured in blocks of 96 KB and
64KB. When accessed from the AHB, each SRAM block is independently single cycle accessi-
ble at full matrix speed (MCK).
The AT91CAP7E Matrix manages a boot memory which depends on the level on the pin BMS at
reset. The internal memory area mapped between address 0x0 and 0x000F FFFF is reserved at
this effect.
If BMS is detected at logic 0, the boot memory is the memory connected on the Chip Select 0 of
the External Bus Interface. The default configuration for the Static Memory Controller, byte
select mode, 16-Bit data bus, Read/Write controlled by Chip Select, allows to boot on 16Bit non-
volatile memory.
If BMS is detected at logic 1, the boot memory is the embedded ROM.
The internal 256 KB ROM is metal-programmable and each AT91CAP7E customer may develop
their own boot program using their own code or a combination of their own code and routines
available from Atmel.
The external memories are accessed through the External Bus Interface. Each Chip Select line
has a 256-MByte memory area assigned.
