MSP430F6746A: PCB design guidelines for F6746A pins

Part Number: MSP430F6746A
Other Parts Discussed in Thread: TIDM-3PHMTR-TAMP-ESD, TIDM-THDREADING, MSP-TS430PEU128

Hi Support,

can we provide PCB design guidelines for specific part MSP430F6746AIPEU?

Customer need to know exactly how to design pin pads and spacing.

Thanks and regards,

Alberto

  • Hi Alberto,

    The customer is encouraged to use the MSP-TS430PEU128 as a template for hardware connections, however it is understood that this will not help with pin pads and spacing since it is a target board with a socket connector. The product's Quality & packaging page also unfortunately lacks the CAD/CAE symbols for the LQFP (PEU) 128-pin package. Package dimensions are provided on page 174 of the Datasheet which fulfills spacing requirements, the pad size should be near the same size or a bit larger than the pin itself. Please refer the customer to the TIDM-3PHMTR-TAMP-ESD or TIDM-THDREADING CAD files (Eagle) for an example of proper PCB layout. The pads are 1.4 x 0.3 mm and separated by 0.2 mm (0.5 mm pitch).

    Regards,
    Ryan
