Other Parts Discussed in Thread: MSP430AFE253, MSP-TS430PW24

Hi,

We are using MSP430AFE253 with SD24 ( 24 bit ADC) . Does Texas provide PCB design guide specific to controller / 24 bit ADC handling Tips.

I am also unable to find stability of SD24 , Hardware circuits like RESET , de-couplers etc. in datasheet / user guide. . Pls guide us.

Regards

Hi Atul Bhakay,

The following Wiki contains all of the MSP430 schematic and layout documents provided by TI: processors.wiki.ti.com/.../MSP430_Schematic_and_Layout_documents

Otherwise there are several online guidelines/tips for routing analog signals that should be applied to the SD24 circuitry.

SD24 parameters are provided on pages 28 to 31 of the device datasheet: www.ti.com/.../msp430afe253.pdf

Decoupling capacitor recommendations can be seen in Sections 22.2.9 and 23.2.8 of the device User's Guide: www.ti.com/.../slau144j.pdf

Signal connections for SBW/JTAG connections are shown in Figures 2-1 and 2-3 of the Hardware Tools User's Guide, which also contains an example schematic and PCB view for the MSP430AFE253 target board (MSP-TS430PW24: Figure B-11, Figure B-12, and Table B-7): www.ti.com/.../slau278w.pdf

Regards,
Ryan
