Part Number: ISO7420FE Other Parts Discussed in Thread: ISO7420 The datasheet for the ISO7420FE specifies operation of both the input and output down to 3V. Assuming the input side is powered to 5V with a logic low on the input. Is it possible that the…
We bypassed the on-board JTAG circuitry and connected an external JTAG board ( https://www.olimex.com/Products/DSP/Emulators/TMS320-XDS100-V3/ ). This worked well for all of the boards. Then we traced the JTAG comms back and found that there was a change…
