Up to 512 kB on-chip flash program memory with In-System Programming (ISP) and In-Application Programming (IAP) capabilities. Flash program memory is on the ARM
local bus for high performance CPU access.
32 kB of SRAM on the ARM local bus for high performance CPU access.
16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
8 kB SRAM for general purpose DMA use also accessible by the USB.
Dual Advanced High-performance Bus (AHB) system that provides for simultaneous Ethernet DMA, USB DMA, and program execution from on-chip flash with no
contention between those functions. A bus bridge allows the Ethernet DMA to access
the other AHB subsystem.
EMC provides support for static devices such as flash and SRAM as well as off-chip
memory mapped peripherals.
Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts.
General Purpose AHB DMA controller (GPDMA) that can be used with the SSP serial
interfaces, the I2S port, and the Secure Digital/MultiMediaCard (SD/MMC) card port,
as well as for memory-to-memory transfers.
