What this 16-bit MSP430 brings to a battery-powered design
The MSP430F46191IPZR: Its standout feature is the integrated LCD driver with contrast control, which directly drives segmented glass displays without an external controller — a major BOM simplification for panel-mount meters and handheld readers.
At 8 MHz the CPUX core executes most instructions in a single cycle.
Peripherals that save external components
Beyond the LCD driver, the peripheral set includes a DMA controller for moving data without CPU intervention, a brown-out reset and power-on reset supervisor, a PWM timer, and a watchdog timer.
