More Flash and RAM - MSP430F5438A Upgrade

Hello,

i developed and got a solution with MSP430F5438A, but now i need to improve my application and i need more RAM and Flash. Anybody know if is there a footprint compatible microcontroller, but with more capabilities?

The principal problem is that i don't have time and resources to development a new hardware.

Thanks a lot.
Best regards

    I don't know the answer off the top of my head, but TI provides a fairly nice Product Selector over at the MSP430 home page. Start by picking "F5 series" and your current chip package, along with the flash/RAM you want (or just "> what you have"). That should reduce the candidates to a sufficiently small number that you can compare the pinouts in the data sheets one-by-one.

    There are no MSP430F54xx device with more flash/RAM than MSP430F5438A. There are some new MSP430F5xx devices with more flash/RAM, for example... MSP430F5358, MSP430F5359, MSP430F5658, MSP430F5659, and plenty of them in MSP430F6xx family. They are in 100PZ package, same as MSP430F5438A, (didn't check) probably with different pin order.

    Or better coding skills :) 16k ram and 256k flash are plenty. The MSPs with USB controller have 18k ram, and some new F67xx devices have 32k. The 67791, for example, has 512k flash and 32k ram. And is huge.
    For storing data, an external flash memory or RAM can be used. Slow, compared to direct memory access, but usually sufficient.

    In total, there are 45 MSPs with 256k and up flash and 16k and up ram (including the 5438 and its brothers)
