Data Sheet

Serial Peripheral Interface (SPI/SCP)

The Serial Peripheral Interface (also known as the Serial Communications Port) is a full-duplex, synchronous,

character-oriented (byte) port that allows the exchange of data with other serial devices. The SCP is a master on

the serial port supporting a 3-wire interface (receive, transmit, and clock), and is a slave on the OPB.

Features include:

• Three-wire serial port interface

• Full-duplex synchronous operation

• SCP bus master

• OPB bus slave

• Programmable clock rate divider

• Clock inversion

• Reverse data

• Local data loop back for test

Universal Serial Bus (USB)

The USB interfaces provide both device and host support for version 1.1 and device support for version 2.0.

Support for the USB 2.0 Transceiver Macrocell Interface (UTMI) specification is included.

Features include:

• USB 1.1 Host port with internal PHY

• USB 2.0 Device UTMI or USB 1.1 Device PHY

• Device support provides 6 end points (3 in, 3 out)

• 1024B FIFO (double buffering of 512B packets)

• FIFOs are not shared between in and out endpoints

• Endpoints do not support high-bandwidth isochronous transfers

• Two USB 2.0 device end points have DMA dedicated channels (DMA to PLB 128)

NAND Flash Controller

The NAND Flash controller provides a simple interface between the EBC and up to four separate external NAND

Flash devices. It provides both direct command, address, and data access to the external device as well as a

memory-mapped linear region that generates data accesses. NAND Flash device data appears on the peripheral

data bus.

Features include:

• 1 to 4 banks supported on EBC

• Direct Interfacing to:

– Discrete NAND Flash devices (up to 4 devices)

– SmartMedia Card socket (22-pins)

• Device sizes 4MB-256MB supported

• (512 + 16)-B or (2K + 64)-B device page sizes supported

• Boot-from-NAND: Execute a linear sequence of boot code out of single page of first block (512B)

• Support DMA to allow direct, no-processor-intervention block copy from NAND Flash to SDRAM

• ECC provides single-bit error correction and double-bit error detection in each 256B of stored data

• Chip selects shared with EBC
