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 AMD 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
