MSP430G2230-EP: Accurate microcontroller selection?

Charles Modrich

Part Number: MSP430G2230-EP
Other Parts Discussed in Thread: MSP430G2230

I'm essentially using this microcontroller as a co-processor for a different micro, and want to make sure my choice of selection here is the correct one.

These are the needs I have:

1. Wakeup MSP on UART RX activity <- needs to not miss ANY bytes that came in to trigger the wakeup at 9600baud

2. Trigger an interrupt pin on RX activity

3. Re-host "buffered" received UART data to main processor via I2C.

4. Go back to sleep after I2C data is sent

5. 3.3V supply power

Given my needs above, do I have the correct choice of MSP selected? Any and all feedback would be greatly appreciated, thank you!

Hi Charles,

So the part you have selected does not have the UART function, just SPI and I2C.

Yes, we do have plenty of MCUs that can do these instructions.

Are specifically looking for an EP rated msp430? lets try to find you an alternative.

regards,

Henok

Hi Henok, many thanks for your help!

I'm not exactly sure what the EP designation is, unlikely we expressly need it. I'm looking at the MSP430 line due to its low power UART, I'm open to whatever flavor(s) you recommend for the task given the requirements above.

Hi Charles,

The EP notation stands for enhanced product. Essentially, this means there are some enhancements compared to the original MSP430G2230 such as a wider operating temperature range.

If you don't need this feature, then I would recommend taking a look at MSP430G2203 (no adc), MSP430G2233, MSP430G2253

regards,

Henok
