Description:

Low cost development board for the Altera EPM240T100C5 (MAXII) CPLD device. Using Altera's free design suite complex schematic or HDL designed can be easily created and downloaded into this development board (hardware programmer required, available here). An on board regulator allows and standard DC socket allows for convenient powering. There is also an on-board crystal to allow your designs to include clocks and other timing functions.

Please note: An external power supply (ideally 5V) is required to power this board.


On-board EPM240T100C5 chip
On-board JTAG interface
On-board 50MHZ active crystal
On-board programmable LED
On-Board 3.3V regulator
5V power supply socket with switch
Easy access to all IO pins via headers
Board size 5CM * 7CM

What pin of the CPLD is connected to the external crystal? I'm pretty now to this, and I need to know how to access it. I tried looking at the schematic file but there is no crystal on that...

The crystal is represented by symbol P9 on the schematic. It should be connected to pin 12 on the CPLD (RI/O_GCLK0p).

Got an idea that it's a complete oscillator - not just a quartz - that's why there's only one connection (and a +vcc).

Hi,

I was unaware that this board required a power supply.
However, looking at http://forum.hobbycomponents.com/viewtopic.php?f=88&t=2076, that does seem to be the case. For this device however, it is a bigger problem, as the board does not seem to support ASP-connection, so there is no way to connect the device without it.

Does this one work for this board as well (fetched from the description of the cyclone board)? http://hobbycomponents.com/cables/789-1m-usb-to-21mm-5v-jack-plug
If so, I suggest it is added to the description. People with no fpga experience might not know this, and it is rather unsatisfying to have to pay for shipping twice, as well as having to wait the extra time to receive it.
You might wanna recommend buying one of those on your ebay listing as well:

Yes you do need to power it via its DC power socket. Ideally using a 5V power adapter, or alternatively you can power it directly via the 3.3V and GND header pins. This is normally the case with large CPLDs, and in particular FPGAs as depending on the design they can consume more power than a standard USB port can supply. As a result, although in most cases powering via a USB port will be fine, depending on your design you may need an external adapter.

The device is programmed via a JTAG programmer, not ASP. In either case most programmers will not power the device (most likely for the above reasons).

Yes that cable is suitable for this development board.

The cable is a relatively recent addition to our product range and so is why it isn't mentioned in the description for this board. It is a good point though, I'll get it added to the descriptions. Edit: However we won't be able to add the cable to the eBay page as we don't sell the cable on eBay and due to eBay policies we can't externally link to it.
