Masked ROM parts - MSP430C

Other Parts Discussed in Thread: MSP430L092

I'm looking for informaiton on masked ROM parts.  I see some information in the MSP430 literature about a MSP430C part.  But I don't really come across much else or any many specifics describing part capabilities.

It's a requirement for my application.  I can't change it.  

I have the following specific question:

1.  Which parts are available for this?  I want to tailor my code design to use resources available on those parts. As an example, I want to use an onboard ADC, but if it's not available, I'll set up a comparator.

    The MSP430x09x devices (C091/C092/L092) are designed to be powered from a single cell, which could be as low as 0.9 V. At this voltage, flash does not work; that these devices use an internal ROM (or download the code from external memory into internal RAM) is not really an intended feature but an unfortunate side effect of the voltage range.

    The power supply and I/O voltage can be at most 1.5 V.

    Unless you intend to ship hundreds of thousands of devices, you should use the MSP430L092 with an external SPI ROM:

    Hi Dexter,

    in addition to Clemens' information another source would of course be the device datasheet (SLAS673).

    Do you have any additional MCU requirements? It could help us to figure out what the best device is for you.

    You might also be interested in code examples, those are part of the MSPWare (drivelib). Try the TI Resource Explorer and browse for the part you're interested in. You'll have some code examples for the MSP430C09x and MSP430L092 devices.

    Feel free to reach out to us with further questions.

    Best regards,

    Britta
