How is the minimum microcontroller spec when using ADS1220?

Other Parts Discussed in Thread: ADS1220, ADS1220EVM, MSP430F5528

Use the ADS1220 to measure the weight with a 4-wire load cell (10KG).
At this time, I want to transmit the output data at 2000sps using RS-232. What is the minimum specification of microcontroller?
Is it possible to review PIC16F1938?

    Hi Chunho,

    Welcome to the forum!  It is rather difficult to determine the minimum micro requirements as I have no idea what else will be done within the micro to process.  The ADS1220EVM uses an MSP430F5528 running with a clock frequency of 25MHz.  This micro also has a USB peripheral set up as a virtual COM port.  This combination is able to capture data at 2000sps and transmit through the USB COM to the PC.

    Best regards,
