The CPLD developing and teaching platform is an ideal platform for developing digital circuits design and CPLD design. Features: 1. Core board and peripherals board The platform consists of a core board and a peripherals board. The core board bears the main CPLD chip. And it is designed to a replaceable mode, which makes the platform support series CPLD chip. 2. Rich peripherals Peripheral resource on peripherals board include 4x4 keyboard, 7-Seg LED, serial ports, VGA port and buzzer, etc. And many optional peripheral modules can also be provided, such as audio module, D/A conversion module, A/D conversion module, LCD module and so on to meet different demands. 3. Scalability It is possible to connect other user defined boards to platform through four expansion headers.
