Product details
Frequently asked questions
Is MSP430F5528IRGC obsolete?
Yes, Texas Instruments lists the MSP430F5528IRGC as Obsolete. No further factory production is planned. The part is available through independent surplus and broker channels, sourced to order against an RFQ.
What is the direct replacement for MSP430F5528IRGC?
The MSP430F5529 is the closest pin-compatible replacement in the same 64-VQFN package, with the same 128 KB Flash and USB peripheral. Note that the F5529 has 8 KB RAM versus 10 KB on the F5528 — check your RAM budget before substituting.
Does MSP430F5528IRGC support USB?
Yes, it includes a full-speed USB 2.0 interface with an integrated PHY, supporting device, host, and OTG modes. No external USB transceiver is required.
What is MSP430F5528IRGC's listed speed?
The CPUXV2 core runs at 25 MHz, delivering roughly 12.5 to 25 MIPS depending on instruction mix.
