The MSP430FG4250IRGZR: The 12-bit DAC handles analog output tasks like set-point generation or sensor excitation without a separate DAC chip. Together they shrink the analog front-end to just the MCU and a few passives.
Housed in a 48-VFQFN with an exposed thermal pad (supplier package 48-VQFN, 7x7 mm). The 32 I/O lines include the LCD segment and common outputs.
Yes, the MSP430FG4250IRGZR includes an on-chip LCD controller that can drive a segment LCD directly, saving the cost and board space of an external display driver.
