Thank you for choosing the Lattice Semiconductor MachXO™ 2280 Breakout Board Evaluation Kit! This user guide describes how to start using the MachXO 2280 Breakout Board, an easy-to-use platform for evaluating and designing with the MachXO PLD. Along with the board and accessories, this kit includes a pre- loaded demonstration design.
Evaluation Board User Guide 2. Features The MachXO 2280 Breakout Board Evaluation Kit includes: MachXO 2280 Breakout Board – The board is a 3” x 3” form factor that features the following on-board components and circuits: MachXO 2280 PLD (LCMXO2280C-3FTN256C) ...
The preprogrammed demonstration design is an up-counter to drive an LED array. The program shows a clock generator based on the MachXO 2280 on-chip oscillator. The counter module is clocked at ~22 MHz (18 MHz – 26 MHz) to illustrate how low speed timer functions can be implemented with a PLD. The 23-bit up-counter further divides the clock to advance the LED display approximately every 200 ms.
When the board is connected to a PC with a USB cable, it is recognized by the ispVM System software as a USB Download Cable. The MachXO 2280 can then be scanned and programmed using the ispVM System software.
This section describes the features of the MachXO 2280 Breakout Board in detail. 7.1. Overview The Breakout Board is a complete development platform for the MachXO 2280 PLD. The board includes a prototyping area, a USB program/power port, an LED array, and header landings with electrical connections to most of the PLD’s programmable I/O, power, and JTAG pins.
This section describes the principle sub systems for the Breakout Board in alphabetical order. 7.2.1. Clock Sources All clocks for the counter demonstration designs originate from the MachXO 2280 PLD on-chip oscillator. You may use an expansion header landing to drive a PLD input with an external clock source.
The USB mini-B socket of the Breakout Board serves as the programming and debug interface. JTAG Programming: For JTAG programming, a preprogrammed USB PHY peripheral controller is provided on the Breakout Board to serve as the programming interface to the MachXO 2280 PLD. Programming requires the ispVM System software.
