CHAPTER 5 FUNCTIONAL DESCRIPTION
UTMI
The USB 2.0 Transceiver Macrocell, it’s the analog circuitry that handles the low level USB protocol and
signaling, and shifts the clock domain of the data from the USB 2.0 rate to one that is compatible with the
general logic.
SIE
The Serial Interface Engine, which contains the USB PID and address recognition logic, and other sequencing
and state machine logic to handle USB packets and transactions.
EPFIFO
Endpoint FIFO includes Control FIFO (FIFO0), interrupt FIFO (FIFO3), Bulk In/Out FIFO (BULKFIFO)
Control FIFO
FIFO of control endpoint 0.
It is 64-byte FIFO, and it is used for endpoint 0 data transfer.
Interrupt FIFO
64-byte depth FIFO of endpoint 3 for status interrupt
Bulk In/Out FIFO
It can be in the TX mode or RX mode:
1. It contains ping-pong FIFO (512 bytes each bank) for transmit/receive data continuously.
2. It can be directly accessed by Uc
3. Support automatic hardware SmartMedia ECC error correction
MHE
It contains 5 MIF (Media Interface)
MIFs
1. CF/Micro Drive MIF
2. SmartMedia/xD/Flash MIF
3. SD/MMC MIF
4. MemoryStick MIF
5. MemoryStick PRO MIF
8051 Core/SRAM/LUT/Mask ROM
An 8-bit Micro-controller to manage card operation, card power, USB Storage Class, data transfer between
USB and card interface, and GPIOs control
