MAX V Board

Getting Started

Power Supply

At the top of the board (near pins 1 and 64) there is a pin header and a jumper that can be used to select how the power the board. 

• If the jumper is on the pin closest to pin 1 and the centre pin the board it powered through the on board 3.3V regulator.

• If the jumper is on the pin closest to pin 64 and the  centre pin the regulator is bypassed and can be powered with an external 3.3V supply. (3.3V Only!!!!)

Markings on the underside of the board also indicate what the jumper positions do.

The MAX V board can be powered by applying 5-12V to any of the pins with a solid white square around it, and ground to any of the pins with a square with no fill (black).

V+ Pins are: 6, 8, 23, 39, 41, 57
GND Pins are on the corners of the board, except for the one closest to pin 64.
This pin next to pin 64 and a 3.3V output pin, that you can use to power other parts of your project/circuit that require 3.3V. Keep in mind that this 3.3V output comes from the onboard regulator, so try not to draw too much current from the board (don't go over 800mA)

On-Board Clock

The is a on board 32.768kHz clock on the board that is connected to pin 42 of the MAX V CPLD. 32,768 might seem like an odd number but it is 2^15 so it is easy to divide with some digital logic and produce clock values in fractions of a second. There as a pin header and jumper in the centre of the board (clk), when the jumper is placed on the pin headers the clock is disabled so pin 42 can be used as a normal I/O pin. Removing the jumper turns the clock on.

Programming

You can program the MAX V board with an Altera USB Blaster. Connect the USB Blaster to the JTAG header on the board. Pin 1 of the JTAG header is indicated by the triangle printed on the board. Additional information about the JTAG header and USB Blaster can be found here.
