HI,

Do you have a reference design of MSP430F5232?

It will be useful to see how power and clock signals are routed as well as the data-lines.

Thank you.

Hi Jason,

We may not have a reference design for that exact MSP430 part number, but probably something very similar. Which clock signals and data lines are you referring to? SPI, UART, I2C, USB?

Thanks,

Ian

Hi, Ian.

Thank you for your support.

We will use one SPI & two I2C.

For the clock, I am not sure what speed to select.

Quick question for you: Does the selection of clock speed depend on what signal is to be used (SPI and I2C in my case)?

Thank you.

Hi Jason,

Your system clock will affect the maximum datarate for SPI and I2C.

The max I2C SCL clock speed is going to be 400KHz for this device.

The max SPI clock can actually run at the same speed as the the system clock. There are setup&hold times given on page 61 of the datasheet.

Thanks,

Ian

Thank you.

By the way, can you tell me which reference design I can take a look & where I can find it?

Have a nice day.

Hi Jason,

I suggest you look at the MSP4305438A Experimenter's Board or the F5529 launchpad for some general purpose layouts. All 5xxx devices are similar enough that this design can help you get started. Both of the provided links have hardware design files available (schematics and layouts)

Thanks,

Ian

Hi,

The MSP430F5529 LaunchPad is a good choice, as Ian suggested. I attached the schematics, which can be found at the end of the F5529 LaunchPad User's Guide: http://www.ti.com/lit/pdf/slau533

Please note that you will be most interested in pages 1 & 2 of the F5529 LaunchPad schematics. This LaunchPad also contains a JTAG debugger, which is implemented with an MSP430F5528, and is shown on schematic pages 3 & 4.

Best,

Rick
