Product information "TC-LATTICE · JTAG Adapter HW-USBN-2B to TC2030"

Short description

JTAG adapter from the 12-pin connector of the Lattice HW-USBN-2B programming cable to a 6-pin 2.54 mm (0.1″) pin header for TC2030-IDC, TC2030-IDC-NL and ECV3-06-IDC cables — for ECP5, CrossLink, MachXO2/MachXO3 and ispMACH. The smallest Tag-Connect footprint for Lattice devices with JTAG.

Connections

Side	Pins	Connector	Pitch
Debugger	12	Socket Lattice HW-USBN-2B	—
Cable (Tag-Connect)	6	Pin header, 2 × 3	2.54 mm (0.1″)

Full pin assignment: in the "Technical data" tab.

Compatible: the Lattice HW-USBN-2B programming cable.

Not, or not directly, compatible

20-pin, 2 × 10, 2.54 mm (0.1″) — ARM connector, e.g. SEGGER J-Link, Keil ULINK, ST-LINK/V2: through the adapter board COLL-ARM20-06-IDC, ARM20-CTX
14-pin, 2 × 7, 2.54 mm (0.1″) — Renesas E1 / E2 / E8a / E20: through the adapter board TC-RENESAS

Application

Programming ECP5, CrossLink or MachXO over JTAG takes four signals plus power. That is exactly what the 6-pin TC2030 footprint carries — on the area of an 0805 resistor, with no connector on the board. This adapter maps the 12-pin HW-USBN-2B connector onto it.

It is not suitable for iCE40: iCE40 has no JTAG and needs CRESET_B and CDONE, which the 6-pin footprint does not carry. That is what the TC-LATTICE-10 is for.

Which Lattice adapter?

Device	Interface	Adapter
iCE40 UltraPlus, HX, LP	SPI with CRESET_B and CDONE — no JTAG	TC-LATTICE-10
ECP5, CrossLink, MachXO2, MachXO3, ispMACH	JTAG	TC-LATTICE is enough
Writing the configuration flash on the FPGA directly	SPI with chip select	TC-LATTICE-10
PROGRAMN driven by the programmer	—	TC-LATTICE-10

In short: JTAG targets with no further demands do fine with the 6-pin; anything that needs DONE, PROGRAMN or a chip select calls for the 10-pin.

The 500 Ω resistor — and why it sits here

The HW-USBN-2B senses the target voltage via VCC. On targets with very low current draw it lifts VCC unexpectedly in doing so. Lattice therefore recommends 500 Ω between VCC and GND — on every target board. This adapter carries the resistor itself; the target board no longer needs it.

Ground first

Lattice mandates it for the HW-USBN-2B, and it holds with the adapter too: when connecting, ground first, then the signals. Otherwise the device can be damaged. The Tag-Connect contacts are all the same length — there is no mating-first ground here.
