Product Specification
Introduction
The In System Flash (ISF) is type of serial flash memory
that is present only on the Spartan-3AN devices, a
sub-family of the Spartan-3A FPGA devices. The XPS
InSystem Flash IP Core is 32-bit slave peripheral that
connects to PLBv46 (Processor Local Bus with Xilinx
simplifications) and provides access to the ISF using
Serial Peripheral Interface (SPI) protocol. The SPI
protocol, as described in the Motorola M68HC11 data
sheet, provides a simple method for a master and
InSystem Flash on Spartan-3AN devices to exchange
data.
Features
• Connects as a 32-bit slave on PLB V4.6 buses of 32,
64 or 128 bits
• Supports four signal SPI interface (MOSI, MISO,
SCK and SS)
• Supports full-duplex operation
• Supports programable clock phase and polarity
• Supports manual slave select mode only
• Supports transfer length of 8-bits only
• Supports local loopback capability for internal
testing of the core
• Supports single SPI master and single ISF slave
environment
• Optional 16 element deep (an element is a byte)
transmit and receive FIFOs
