The uDiskOnChip controller enables the highest performance for USB 2.0, coupled with the best
security and reliability available. The controller’s firmware inherently supports multi-vendor flash
components to provide flexibility and guarantee delivery to our customers.
As with other products based on M-Systems’ technology, the uDiskOnChip controller contains
M-Systems’ patented USB device interface, which is compatible with USB 2.0. The controller also
has a high-speed 32-bit RISC microcontroller with Idle and Deep Power-Down modes for power
management.
The uDiskOnChip controller architecture is illustrated in Figure 2.
