The MSP430 FET will never be the same

43oh just came with a post showing the new MSP430 Wolverine that is coming out really soon. This is an expanded version of the MSP430 using FRAM instead of Flash.

TI Has done some pretty interesting things on the board. An e-ink display with capacitive touch.  E-ink is a very good pairing with the MSP430 because they’re both targeted towards low power. E-ink displays can hold on to the last data displayed for extended periods of time without the need for power, and this works great for a lot of applications. Although the board is greenish, the actual board released will most likely have a different color scheme.

Despite all this I want to discuss something that we don’t see anymore. Take a look at the back of the board. This is the area usually reserved by TI for the on-board FET debugger.
I’ve been using the MSP430 for over 5 years and for all that time the FET has been built around an MSP430 paired with a TUSB3410 USB to UART, as well as EEPROM and a few external elements. On the Wolverine board, this isn’t there. The markings are not clear, but I believe TI has finally integrated the FET. The main chip that is at an angle is likely an MSP430 with integrated USB capabilities. There’s no longer a need to use an external TUSB3410 device, so the BOM is lower. It makes supporting the platform better. You can use DFU or other mechanisms and its a nice way to display the MSP430 USB capabilities.
The F5529 Launchpad board changed things a bit. The TUSB3410 was replaced by a TUSB2046.
Soon we’ll know.
