Details of our PCI core here.
Board Features
Main FPGA
XilinxTM
XC3S2000
SpartanTM-3 FPGA.
Startup FPGA
XilinxTM XC3S200A-1400A SpartanTM-3A FPGA. XC3S200AN also possible for secure applications.
Flash Memory
Two 128 Mbit SPI Flash Memories. First one is used for
configuration but has spare space for microprocessor code etc.. Device 2 is
totally independent and free to use.
SDRAM Memory
256Mbit, X32 SDRAM. 64-512 Mbit possible.
DIL Headers
Mulldonnoch2 has our enhanced DIL Headers
with 3.3V and DGND(0V) power strips. There is also a dedicated regulator
for each header that can be set by
whatever primary module is plugged in (supporting modules only and one
in specific location). This regulator can also be controlled by the
Startup FPGA allowing circuits to be switched on/off for power
management purposes. The regulator voltage/s also can be selected as
appropriate bank I/O voltage/s on the Main FPGA.
The RHS DIL Header has a 34 high header giving 66 I/O. Top pins and inner pins are power (note orientation to bottom of board).
The LHS DIL Header has a 34 high header giving 66 I/O. Top pins and inner pins are power.
The TOP DIL Header shares some pins with other headers and other board features. Please check pinout usage carefully before using this header.
Moel-Bryn
Mulldonnoch2 has one Moel-Bryn socket for high performance expansion. Modules like our Swinyard1 can be used in this socket.
PCI104 Interface
32 bit, 33 MHz, 3.3/5V PC104+ interface (PCI) capable of being used
for other bus standards or as 5V tolerant general I/O. This interface
also support signals to allow board to operate as motherboard and to
handle request/grants from add on boards such as our Hollybush1,
Hollybush2 or other industry standard boards.
USB Serial Interface
FT232R
based serial interface. When plugged into a PC etc. this appears as
serial port (other modes possible too). PC drivers available from FTDI.
This interface can also be used to remote boot or configure the Main
FPGA.
Ethernet Interface
Micrel KSZ8851SNL SPI Ethernet controller. This interface can also
be used to remote boot or configure the Main FPGA.
MAC Address
There is a Maxim DS2502 fitted to the Mulldonnoch2 to provide a unique MAC address. A second device site option is also available for applications that need 2 MAC addresses. Both devices are accessible though the Startup FPGA.
PS2 Interfaces
Two PS2 interfaces to support mouse and keyboard. If not used for
PS2 eight 5V tolerant signals are available. Four of these signals have
pullups to 5V to facilitate interfacing to 5V CMOS logic devices. This
interface can also be used to remote boot or configure the Main FPGA.
Real Time Clock
DS1306 real time clock chip on board. Battery holder on board to
support un-powered time keeping and data storage..
General Clocks
Two 3.3V 8 pin DIL oscillator sockets for user fitted clock modules. Fixed 32Mhz and
25MHz oscillators on board. RTC 32.7678KHz also available. Startup FPGA can multiply
or divide any of these frequencies. All of these are connected to the
startup FPGA and any 4 can be routed to the Main FPGA. A clock can also
be supplied by FT232 USB chip but needs to be plugged into USB hosting
device.
High Accuracy Clock(option)
1ppm 10MHz clock site supporting D75A-010.0 MHZ TCXO.
LEDs
3 LEDs connected to Startup FPGA. 5 LEDs connected directly to Main FPGA.
DIP Switches
8 DIP switches.
ZIF Expansion(option)
ZIF socket option to support ancilliary items like remote displays.
Power
Mulldonoch2 has several different ways in which it can be powered. Which can be used depends on your add on card requirements. Mulldonoch2 itself is capable of operating from a single 5V supply.
Option1 - 2.1mm Power Jack.
Option2 - USB connector (make be limited by your USB host or power supply).
Option3 - Disk Drive connector.
Option4 - Enterpoint PC104 power card (12-48V input).
On board there are 6 amp switching regulators for 3.3V, 2.5V, 1.8V and 1.2V. There are also user configurable 1.2A regulators for each of the DIL Headers. There is also a LP2996 reference supply regulator.
There is a twin power structure allowing the board to idle in a low power mode and to wakeup and power the Main FPGA and PCI104 stack. This feature is available only in some source power options and configurations.
Programming Cable
Standard 2x7 2mm programming header.

OEM Boards
Mulldonoch2 can be supplied either as a raw un-programmed board (development board) or as fixed functionality board. As a un-programmed development board you are responsible for the FPGA internal design. As a fixed functionality board we deliver pre-programmed boards with a FPGA design by Enterpoint. Please ask for a quote for your exact requirements.
Taxes and Duties
For the UK we will apply 15% VAT to goods and courier charges.
For non-UK EEC countries we will apply 15% VAT to goods and courier charges unless you can supply a VAT number, with registration details, that we can verify. If we can not fully verify your VAT details then VAT will be applied at 15%. The application of zero rate VAT to a shipment will be at our discretion under advice from UK Customs and Excise. If items are shipped at zero rate VAT you will responsible for accounting for VAT to your local authorities. No other duties or taxes should apply to products shipped to the EEC countries.
USA - We believe that Mulldonoch2 will not attract duty or MFP (manufactured foreign product) fee of US $2 for a single board. The postal service or courier may charge handling if there is a collection of such a fee. This is our understanding of the rules but you should make you own enquires to confirm this. Please give us feedback if you can confirm or add to this understanding.
For other countries duties and taxes do vary.
Applying duties and taxes may be collected by the courier,
or postal service, from you upon delivery. Please check with
your local authorities if you are unsure of rates. We will add
more information as we find it out on other countries.
Derivative, Turnkey Designs and Licensing
We are happy to offer derivative designs of Mulldonoch2, or
expansion modules, to customers with special requirements. We can also
license this board, or a derivative, for your own manufacture. Please
ask for a quote if you are interested in these services or products.
