Other Parts Discussed in Thread: MSP430FR2633
I wanted to make sure that I'm looking at the right parts. I believe the new parts are the MSP430FR267x parts, but when I compare the datasheets to our current MSP430FR2633 part, they all say "Increased immunity to power line, RF, and other environmental noise. Built-in spread spectrum, automatic tuning, noise filtering, and debouncing algorithms." If the FR267x has better noise immunity, is that quantified somewhere?
- If we do go with the FR267x family, it looks like FR2672 would be fine for our application. It has the 16 Captivate channels we need, and it has the same memory size as our current FR2633. Any other differences to be aware of?
- Lastly, all of these parts list the voltage range for Vcc as 1.8V - 3.6V, which means we can't actually run in with a nominal VCC of 1.8V, as there will always be some variation and VCC could drop below 1.8V. Are there any plans for a part with true support for 1.8V (so a VCC spec that goes down to 1.65V or 1.7V)? Our next gen design is switching almost entirely to 1.8V IO, and the MSP430 is one of the few parts that doesn't support 1.8V IO and requires level translators. We just want this on the I2C, interrupt and SBW lines.
