Product details

8 MHz core — what it means for the application tier

At 8 MHz, this part is not a high-throughput controller. It fits periodic sensor polling, serial protocol bridging, and slow-loop regulation where the CPU idles between events. The 256-byte RAM limits buffering — expect to process data in-place or use the Flash for lookup tables rather than large packet queues.

Obsolete — sourcing reality for this line item

The MSP430F133IRTDR is marked obsolete by Texas Instruments. No official successor is listed in the available records. For a BOM line that requires this exact order code, supply runs through independent-distribution surplus and broker channels. Availability and current pricing are confirmed at quote time against an RFQ; expect to work with date-code spreads and sealed-reel lots where condition can be verified.

Frequently asked questions

Is MSP430F133IRTDR obsolete?

Yes, Texas Instruments has marked the MSP430F133IRTDR as obsolete. No direct replacement has been announced, so sourcing depends on surplus inventory through independent channels.

What is MSP430F133IRTDR's listed speed?

The core runs at 8 MHz, which is the maximum clock frequency for this MSP430x1xx device.
