MSP430G2553: Problem with the TSSOP version of MSP430G2553

user1756427

Part Number: MSP430G2553

Hi there, I'm having a problem with the MSP430G2553 in TSSOP form. I have my system working in a Launchpad with acc110L Air module. Everything works fine with the PDIP format but with the TSSOP. I have 2 weeks looking for the problem. I made my PCBs with the TSSOP and is not working. I bought a ZIF socket for the TSSOP and wire it to the working system and it doesn't work. The software I use is the same for both formats PDIP and TSSOP.

Any idea?.

I have a radio link working with the Launchpad and the BoosterPack. Those comes in PDIP. I just program the same kind of chip (MSP430G2553) in TSSOP format mounted it in a ZIF that I wired to test the link. Check wire by wire and no signal on the chip legs CSN, MISO, MOSI and Clock. I have the final PCB with the same configuration of the LaunchPad and BoosterPack to use in a hand held remote control I have working for Wi-Fi. everything checked wire by wire and I have the same picture, no CSN, MOSI, MISO and Clock.
