Craignell28/32/36/40(formerly models x/1/2/3) offer component replacements, component enhancements, or simple FPGA prototype solutions. They come in industry standard DIL package outlines with 28, 32, 36, 40 pins. Operating from a single 3.3-5V supply the modules use bus switches to make all I/O 3.3V-5V tolerant. There are also pull-up resistors to the input voltage to ensure that outputs achieve 3.3V or 5V CMOS levels.

Typical applications might include replacing 16450, 16550, 8250, 2691, 2692 UARTS with higher speed alternatives. As an example Enterpoint's SuperUART IP can provide a baud rate of between 0.000001 Baud and 7.5MBaud when used as part of FPGA design hosted on a Craignell module.

FPGA

Craignells come fitted with either a 100,000 gate (Xilinx XC3S100E) or 500,000 gate (Xilinx XC3S500E) Spartan-3E fitted.

I/O

The following I/O are available on Craignell models.

CR28 - 26 user I/O. (28 pin 0.6"(15.24mm) wide DIL)

CR32 - 30 user I/O. (32 pin 0.6"(15.24mm) wide DIL)

CR36 - 34 user I/O. (36 pin 0.6"(15.24mm) wide DIL)

CR40 - 38 user I/O. (40 pin 0.6"(15.24mm) wide DIL)

Memory

Craignells have a M25P40 (4 Mbit) serial flash that is used for both configuration of the FPGA and for user application storage. Larger devices may be available for special requirements.

Oscillator

Craignell modules have a 40MHz oscillator on board.

Pricing

The pricing table below is for Craignells fitted with commercial temperature grade silicon. We can offer industrial temperature grade on volume orders at extra cost. Please contact sales for more details of special configurations we can offer.

Part Codes

Craignell part codes are typically formed as follows:

IP, Custom Pinouts and Design Services

Special pinout versions of Craignell modules and IP can be supplied for specific component replacements. Contact board sales for details. We can also offer custom IP or designs to allow Craignell modules to operate as system performance enhancements e.g. a replacement for a 150nS flash memory that runs at 15-20nS access time giving a massive microprocessor performance increase. With Craignell modules we can offer turnkey solutions to help you need solve obsolescence or performance issues. Craignell modules will have a long product lifetime with the main part of the modules being the FPGA which itself is expected to have a 10-20 year production availability.

Craignell modules can be supplied full programmed and ready for your production line. Please ask our board sales for a quote if you wish to use this service.

We can offer customisations of any of our products so if have an application our existing range does not cover please ask for a quote on your specific requirement.

Application Examples

High speed, or customised, 8051 or other 8bit microprocessor replacement.

High speed 8086 core. Details of the implementation on the Craignell family development board Drigmorn1 is here.

Obsolete Flash Memory replacement.

Higher performance, or obsolete, UART replacements.

Higher performance 82C55 replacement. (Enterpoint already has an IP core).

Higher performance, or more counters, 82C54 replacement.

Larger Flash, or Eprom, replacement for existing memory (intelligent paging  mechanism possible).

PAL or GAL replacement. Please ask about our forthcoming N versions.
