ARM7TDMI CPU, which serves as the hardware infrastructure for the M-Systems flash
controller algorithm.
M-Systems Flash Controller, the heart of the system, which is responsible for the
flash-handling algorithm, flash timing, and Error Detection and Correction.
USB (PHY and Digital) Controller, embedded in the uDiskOnChip controller, which
interfaces with all external interactions via an external USB connector.
Crypto-Core, the hardware engine that provides security functions and services to be used by
the controller.
SRAM, for running the controller program faster and more efficiently.
ROM, for running the boot code and additional service program.
Clock Mechanism, which drives all clock sources, some from the crystal oscillator and others
from the PHY PLL.
Reset Mechanism, which restores the reset states of the system, and forces the controller to
perform the boot procedure. The Reset state causes all cores to move to Reset mode.
Timers and Counters, including the device timer, watchdog, and general-purpose
timer/counter channels.
NAND Flash for data storage.
Crystal Oscillator 12.000 MHz, the main clock source.
3.3V Voltage Regulator to supply a stable power supply to the circuit and for accurate and
reliable operation.
LEDs for indicating controller activity.
