IP Compact Flash
Dynamic Engineering — June 2005

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
