TI has marked the MSP430F5524IYFFR as obsolete. No official successor order code is listed. For new production, verify pin-compatible alternatives against your firmware.
The -40 to 85 °C operating range covers industrial environments. The 64-DSBGA package requires controlled reflow and X-ray inspection.
No official successor is listed. The closest pin-compatible alternatives are the MSP430F5524IYFFT (same memory, different reel suffix) or the MSP430F5528IYFFR (128 KB Flash, 8 KB RAM). Verify firmware and peripheral compatibility before substituting.
The core runs at 25 MHz, which is the maximum CPU clock for the MSP430 CPUXV2 in this device.
The two parts share the same die and memory configuration (64 KB Flash, 6 KB RAM). The suffix difference indicates a different tape-and-reel packaging option — the IYFFR is in Tape & Reel; the IYFFT may use a different reel quantity or carrier tape. Electrically they are identical.
