Note: This FPGA’s built in Flash can be used to store the configuration bitstream, and hence to boot-config the
FPGA. This allows using the board stand-alone. That is not obvious in the description, and if a reader is
familiar with other FPGAs, they might assume the lack of external serial flash means no stand-alone operation.
And it would be encouraging to add the step of programming the flash for stand-alone operation in the tutorial.

This is assuming I read the datasheet correctly.

Correct, the flash is on the MachXO2 chip itself. The TinyFPGA Programmer programs the FPGA
configuration flash by default. I can update the guide so this is more clear (https://tinyfpga.com/a-series-
guide.html). The FPGA configuratino flash is fast enough and durable enough that programming the
FPGA config RAM is not worthwhile.

Ah, good to know! Thanks

Looks interesting. Can you share the IO compatibility? Is it 5V tolerant? What kind of socket does it need? Do
you have a datasheet? (there’s no DS under “DOCUMENTS”). I know it’s Friday, but another minute authoring
the product summary page could save a lot of time. Thanks! -Mark

Hi Mark, you are right! I should have sent SparkFun the MachXO datasheet:
MachXO2FamilyDataSheet.pdf.
The MachXO2 FPGA used in the TinyFPGA AX2 is not 5V tolerant, you’ll want to use a level shifter or
voltage divider to drive 5v signals into the board.
The board IOs are set on a 0.1" grid compatible with breadboards and prototyping boards. Socket
compatibility depends on the pins you use. That said, the pins are 0.6" apart from the left to right side of
the board and there are 12 pins on each side of the board.

In 2003, CU student Nate Seidle fried a power supply in his dorm room
and, in lieu of a way to order easy replacements, decided to start his
own company. Since then, SparkFun has been committed to sustainably
helping our world achieve electronics literacy from our headquarters in
Boulder, Colorado.
No matter your vision, SparkFun's products and resources are designed
to make the world of electronics more accessible. In addition to over
2,000 open source components and widgets, SparkFun offers
curriculum, training and online tutorials designed to help demystify the
wonderful world of embedded electronics. We're here to help you start
something.
