dlk51 - FPGA, 8051 CPU and PC link on board You know the normal, in large varieties available 8051 based microcontroller boards? Inflexible, poor performance? This board can do a few things more: FPGA PC interface complete,  free of charge development environment available several independent program memories (4 x 64KByte) two independent FPGA configuration memories Use your 8051 knowledge effectively, release the CPU from time consuming computations - do them via hardware within the FPGA. Add special peripherals (like an array of 24-bit up/down counters, incremental decoding or some co-processors...)  to the 8051. The ' dlk51 ' is a complete ´dlk´ based system, including integrated power pack at a size of 8x10cm. It offers a stable, 8051 based starting point, for the realization of a reprogrammable system. complete package with hard and software all reconfigurable design ´all in one´ package for C, VHDL, logic and microcontroller, application and training Hardware ´dlk51´: FPGA xc2s50 (optional xc2s100) PLD xc9572xl 8-bit 8032 CPU with 11MHz0592 clock serial RS-232 interface connected to CPU 16Kbit I²C EEPROM connected to CPU CPU can be operated in bus or I/O mode external CPU bus connected to the FPGA 512Kx8 flash memory for CPU and FPGA two LED's for debug and indicator purposes LCD interface reset monitor IC for undervoltage identification and external reset complete 3V3 Design 2 independent FPGA configuration files in the flash memory, select boot memory via jumper 4 independent 64Kx8 CPU program files in flash memory, selectable via ´dlk51´ software or FPGA configuration PC or 8032 microcontroller can work as masters on an internal bus fast data transfer (500KBytes/sec, typical) to/from PC via PC parallel printer port interface, connector D25 male integrated linear power pack, input voltage 8-12V DC/12V AC/1500mA (optional 5-12V DC/800mA) with connector type DIN45323 all signals available at 96-pin connector DIN 41612  extension boards can be attached ´inline´ or as stack printed circuit board size 80x100mm approx. 92% of the internal xc2s50 FPGA resources (without PC interface 100%) + 32 unresticted I/O´s available for user applications emulation mode for Xilinx JTAG download cable (DLC5) loadable via FPGA universal digital logic kernel for applications, test, development and training Extent of delivery: hardware ´dlk51´ CD-ROM containing software ´dlk51´, manual in PDF format, schematic in EAGLE format, applications including source code for FPGA and 8051 documentation in english language PC interface cable, D25male/D25female, 1:1 optional: wall plug-in power supply
