Product Description
The In System Flash (ISF) is type of serial flash memory and it is present only on the Spartan™-3AN devices. The Spartan™-3AN FPGA family is the sub-family of 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.
Key Features and Benefits
- 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
