IP Compact Flash

Dynamic Engineering — June 2005

IP Compact Flash

Type 1 [standard] IP module

  • 1 socket built in with the ability to use a transition module to add a second socket. Socket operates in true IDE mode
  • 8 and 32 MHz operation IP Module bus operation
  • ID PROM is byte wide, internal control register is word wide, CompactFlash module is word wide for data path and byte wide for control
  • The IDPROM is build into the Xilinx
  • "PROM" contents are available to determine the current revision of the IP-CF and to determine the slot location
  • The user manual has the expected data content definition
  • Wwrite cycle to the CompactFlash is pipelined with an early termination to the IP host
  • Pipelining reduces the access time in writing to the Flash memory
  • Read cycles wait for data to be available from the memory module
  • Control registers are read-writeable I/O, ID, INT spaces supported
  • Interrupt level 0 is used to route the CompactFlash interrupt to the host computer
  • Interrupt is maskable and pollable
  • +5 V internally, +5 V routed to CompactFlash socket
  • P5V also routed to IO connector via "self-healing" fuse
  • Current levels determined by hardware installe
  • An oscillator position is provided on the fab
  • The oscillator is not used with the base design
  • Custom versions with special frequency requirements can be supported
