16-bit MSP430 at 25 MHz — 64 KB Flash, 8 KB RAM in a 64-DSBGA
The Texas Instruments MSP430F5227IYFFT is a 16-bit microcontroller from the MSP430F5xx family, built around the MSP430 CPUXV2 core running at 25 MHz. The 64-DSBGA package (0.5 mm pitch, 64-ball wafer-level chip-scale) keeps the footprint small — 4.5 mm × 4.5 mm — but the fine pitch and exposed die mean the PCB layout must match the DSBGA land pattern exactly; a 4-layer board with microvias is typical for routing out all 31 I/O and the supply rails.
On-chip peripherals and connectivity for sensor and control loops
The MSP430F5227IYFFT integrates a 12-channel, 10-bit ADC (A/D 12x10b) for direct sensor sampling, plus a DMA controller, PWM timer, brown-out reset, and POR — enough to run a closed-loop motor or battery-management algorithm without an external ADC. The internal oscillator eliminates the external crystal for most timing tasks, though the 25 MHz core clock still needs a stable supply decoupling scheme.
Quantities are lot-specific; traceability and date codes are confirmed at RFQ. The 64-DSBGA package is moisture-sensitive — verify the MSL level and bake requirements before reflow if the parts have been in storage.
