Frequently asked questions

Where can I source MSP430F6438IZQWR if the part is obsolete?

Sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — independent brokers and excess-inventory distributors carry the remaining stock; lead times and lot conditions vary by source.

What is the MSP430F6438IZQWR speed rating?

The MSP430F6438IZQWR runs at 20MHz on the MSP430 CPUXV2 core — a 16-bit architecture, not 32-bit, so clock-for-clock it delivers less compute throughput than an ARM Cortex-M at equivalent MHz.
