Faster Flash Programming via FPGA and IJTAG

With tremendous growth in capacity, programming NOR and NAND flash memories at full functional speed is a must. But how? Here are the ins and outs on using an onboard FPGA and IJTAG, the IEEE 1687 Internal JTAG standard.

Historically, most in-system programming methods took advantage of another deviceโ€™s JTAG port to access memories which lack JTAG. Now, more advanced IJTAG-based programming methods use an FPGAโ€™s JTAG port and speed up the programming process by as much as 1,000 times, reducing programming times dramatically from over 10 minutes to seconds! And production time plummets too.
