What the MSP430F5326IRGCT brings to a firmware build
The Texas Instruments MSP430F5326IRGCT is a 16-bit MSP430 CPUXV2 microcontroller running at 25 MHz, packing 96 KB of Flash program memory and 8 KB of RAM. It sits in the MSP430F5xx family — the generation that brought a unified clock system and a DMA controller alongside the usual low-power draw. This part is aimed at industrial sensor nodes, battery-powered instrumentation, and control loops where the 12-channel 12-bit ADC handles multiple analog inputs without an external mux. The 64-VFQFN package (9×9 mm) with exposed pad gives a solid thermal path for moderate current loads, though the real draw here is the peripheral set: I²C, SPI, UART, plus LIN and IrDA for automotive or building-automation links.
25 MHz core — what it buys you in timing and wake-up
The 25 MHz clock rate on the CPUXV2 core translates to a 40 ns instruction cycle for single-cycle operations. The internal oscillator keeps the clock tree simple; no external crystal needed unless you need tighter tolerance for CAN or USB.
Memory split: 96 KB Flash, 8 KB RAM — where the firmware lives
96 KB of Flash and 8 KB of RAM are available. The DMA controller helps by moving ADC results directly to RAM without CPU intervention.
