JTAG is a 4-wire protocol defined by the IEEE (Std 1149.1-2013). Lattice devices (and others) by following the setup described below. Mouser, and it can be used directly as a programming adapter for Is available for approximately $20 from distributors like Digi-Key and Lower cost option available: FTDI FT2232H Mini Module. Programming adapter (perhaps even designed onto the customer board).Īlthough the Lattice cable is relatively low cost, there is an even Who desire to program their PLDs or FPGAs with a custom JTAG Lattice did it right by not making things difficult for customers
