Product details

Connectivity and peripheral set

No CAN or USB on this die, so designs needing those interfaces must add an external bridge or step up to the MSP430F5xx CAN variants. The 10×10-bit ADC samples at a rate adequate for slow analog channels — thermocouple conditioning, pressure transmitter readback, or battery voltage monitoring.

Industrial temperature range and package

Rated -40 to 85 °C, this part fits factory-floor enclosures, outdoor telecom cabinets, and HVAC controllers. The 9x9 mm body and 53 I/O demand a four-layer PCB for clean routing.

Frequently asked questions

What is MSP430F5255IRGCT's CPU speed?

The CPUXV2 core runs at 25 MHz, which is the maximum clock for this device. That throughput handles real-time control loops and serial protocol framing without wait-state penalties from the 128 KB Flash.

What is the closest pin-compatible alternative to MSP430F5255IRGCT?

Within the MSP430F5xx family, higher-density parts like the MSP430F5438A (256 KB Flash, 16 KB RAM) share the same 64-VFQFN footprint and peripheral set. Verify the exact memory and ADC channel count against your firmware image before switching.
