The Craignell modules, from Enterpoint, offer alternative procurement solutions for hard to find components in DIL28, DIL32, DIL36 and DIL40 packages. The heart of the Craignell modules is a Xilinx Spartan-3E FPGA, which performs the logic or memory function of the obsolete component being replaced. The high density of the FPGA solution allows functions of up to 500,000 gates to be implemented. This allows logic functions as complicated as a 8088 microprocessor or memory devices as large as 16Mbit to be replicated in a single Craignell module. The Craignell modules are available now and are priced from GBP£25, US$50, in 100 off quantities.
In addition to the FPGA, Craignell modules contain power regulators and I/O buffering to allow operation from a single supply between 3V and 5.5V and can tolerate and drive CMOS levels on all I/Os making the module highly adaptable.
Enterpoint offers the Craignell modules in either raw un-programmed format for customers to implement their own logic functions or as turnkey solutions with design of replacement logic functions already implemented. Typical replacement, or enhancement, functions replicated in Craignells include Microprocessors, UARTs, PIOs, Counter Timers, Clock Generators SRAM, Eprom, Flash, FIFOs and Dual Port Memories.
