ARM7TDMI-S processor, running at up to 72 MHz

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.
8 kB/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.

Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts.

 General Purpose DMA controller (GPDMA) on AHB 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.
