    Hi Abhishek,

    The MSP MCU lineup meets most of your requirements, except for the EBI. I recommend reading the datasheets and user guides for the devices I'll mention to verify they meet the requirements you are looking for. We have two MSPM0 devices that meet most of your specs: the MSPM0G1519 ($0.720xku) and the MSPM0G3519 ($0.750xku.) However, these devices will be released to the market in the near future, so I recommend talking with TI's sales team about them.
    If you need an MSP430 alternative that we currently have in stock (we recommend the M0 devices), you can try the following MSP430 MCUs I got from TI's MCU finder tool. However, these devices' voltage levels typically are around 3.3V (though the M0 MCUs should support a little more than 5V.)

    Best Regards,

    Diego Abad

    Can you pls suggest the TI MCU/MPU series which supports the External Bus interface.

    Hi Abhishek,
    The MSP Family doesn't explicitly support EBI. I would recommend the Sitara processors (and posting a similar thread in their E2E) since some models seem to support it.
