MachXO PLD控制開發(fā)套件

MachXO Control Development Kit

The MachXO?Control Development Kit is a platform for rapidly prototyping system control designs using MachXO PLDs. The kit features the MachXO LCMXO2280 device, Power Manager II ispPAC-POWR1014A, 2 Mbit SPI Flash and 1 Mbit SRAM memory, a temperature sensor, an expansion header for I2C and SPI interfaces, and several LEDs and user switches.

Using the preloaded?control system-on-chip (Control SoC) design provided with the development kit, you can now test within minutes board?control functions including fan speed control based on temperature monitoring, LCD?control, complete power supply monitoring and reset distribution in conjunction with the Power Manager II POWR1014A and 8-bit LatticeMico8 microcontroller.?You can then build your own designs using the free downloadable reference design source code, implementing these features in less than an hour. The board also features USB channels for JTAG programming and debugging from a host PC. A prototype area provides access to a variety of PIO banks of the MachXO PLD and the on-board I2C bus. The board can be controlled with a menu driven interface via terminal programs running on a host PC.
