CY7C68013 EPM1270 CPLD has usb development board

Onboard high-capacity ALTERA MAXII EPM1270 series CPLD chip, ISSI61LV2516 256 k * 16 bit SRAM memory and USB2.0 high-speed CY7C68013A chip, constitute a perfect logic and data transmission system. CPLD so pin all leads, and all on board printing layer flag pin number, convenient and practical use. 68013 chip external expansion of the large capacity of 24 block lc64 EEPROM memory chips, enough CY7C68013A used to store program.

Bat EPM1270 positive, ISSI61LV25616 CY7C68013A, 24 lc64 Two leds, two buttons, 5 V to 3.3 V power supply chip, CPLD IO extension of needle. The board can be external input 5 v power supply can also be powered by USB.
