RobG 1,892 Posted February 6, 2013 Share Posted February 6, 2013 What is TI's memory of choice? I need to use memory in my project (serial SRAM and EEPROM,) but I don't want to use anything from TI's competitors. Quote Link to post Share on other sites
bluehash 1,581 Posted February 6, 2013 Share Posted February 6, 2013 What is TI's memory of choice? I need to use memory in my project (serial SRAM and EEPROM,) but I don't want to use anything from TI's competitors. They use Winbond Serial flash. You can find them used alot in the Stellaris kits, specifically in RDK-IDM-SBC Firmware Package under stellarisware. You can integrate it with fatfs too. There are examples of that too.

spirilis 1,265 Posted February 6, 2013 Share Posted February 6, 2013 I was gonna say FRAM, but I think that's what they'd "like" your memory of choice to be... :-D Quote Link to post Share on other sites
RobG 1,892 Posted February 6, 2013 Author Share Posted February 6, 2013 Well, I was going to use Ramtron's (Cypress Semi) FRAM chips, but those suckers are too expensive. Quote Link to post Share on other sites
roadrunner84 466 Posted February 6, 2013 Share Posted February 6, 2013 Fram is nice and all, but unless you have a specific need for it, you're probably more cost effective going with flash or sram. Quote Link to post Share on other sites
nemui-kuma 8 Posted February 7, 2013 Share Posted February 7, 2013 For serial Sram your only choice is Microchip, Onsemi has 4 serial sram chips, but they are smaller and more expensive. For serial flash, there are a lot of choice, but i guess companies who only make memory chips aren't Ti s competitors really (like Micron). Rickta59 1 Quote Link to post Share on other sites
jpnorair 340 Posted February 7, 2013 Share Posted February 7, 2013 Are you a TI employee? Go with the best solution for your app. I have a project with ST and TI components on the same board... the universe did not collapse. Also, as I'm sure you know, MSP430 has no external memory bus option. IMHO EEPROM is normally your best choice as an external memory, apart from FRAM or MRAM. If you need more SRAM in an MSP430 project, really you need to upgrade your MSP430. veryalive 1 Quote Link to post Share on other sites
veryalive 49 Posted February 7, 2013 Share Posted February 7, 2013 Hi - I was following this thread. In the spirit of innovation (which is why many of us are here) and since nobody mentioned it yet -- has anyone checked Everspin MRAM out of Chandler AZ? Looks like another magnetic storage in various handy pinouts / sizes / speeds. Has anyone gotten their hands on this technology yet? Sampled it? I'm sure pricing is fluid and high as it is new.

RobG 1,892 Posted February 7, 2013 Author Share Posted February 7, 2013 I bought all bunch of Winbond chips from DigiKey last night, great prices, exactly what I needed. Plus shipping was under $3! Quote Link to post Share on other sites
