Low-Cost and Optimized Two Layers Embedded Board Based on ATmega32L Microcontroller and Spartan-3 FPGA
Microcontrollers and FPGAs both are widely used in digital system design. Microcontroller-based instruments are becoming increasingly widespread. This paper presents design and implementation of a new low-cost and minimum embedded board based on ATMEGA32L AVR microcontroller and Spartan-3 (XCS400-4PQG208C) FPGA in two layers with mount elements on top and button of board. Using of AVR microcontroller in proposed board it adds many features include Analog to Digital Converter (ADC), Digital to Analog Converter (DAC), 32 Kbytes flash memory, 2 Kbytes SRAM, 1024 bytes EEPROM memory.
