3.2. Architecture
Integrated system for embedded Ethernet / USB / SAR
Fully 16/32-bit RISC architecture
Efficient and powerful ARM7TDMI core
Little/Big-Endian mode is supported basically, but the internal architecture is big-endian.
Cost-effective JTAG-based debug solution
Supports Boundary Scan
3.3. System Manager
8/16/32-bit external bus support for ROM/SRAM, flash memory, DRAM and external I/O
One external bus master with bus request/acknowledge pins
Supports for EDO/normal or SDRAM
Programmable access cycle
Four-word depth write buffer
Cost-effective memory-to-peripheral DMA interface
3.4. Unified Instruction/Data Cache
Two-way set-associative unified cache (4Kbytes)
Supports for LRU (least recently used) Protocol
Cache is configurable as internal SRAM
3.5. SAR/Utopia Interface
Directly supports ATM Adaptation Layer Five (AAL5) Segmentation And Reassembly
Segments and reassembles data up to 70Mbps
A glueless UTOPIA level 2 interface is supprted (for receiving and transmitting ATM cells with SAR, it
is a standard ATM interface between ATM link and physical layer).
3.6. Ethernet MAC
2 DMA engines with burst mode
Full compliance with IEEE standard 802.3
Supports MII interface (7-wire 10-Mbps interface is also supported).
