Mixed-signal MSP430 with on-chip ADC and DAC
It integrates 24 KB of program Flash and 256 bytes of RAM, along with a 5-channel 16-bit ADC and a single 12-bit DAC — a combination that saves an external converter on sensor-interface or closed-loop control boards. The 48-VQFN package (7x7 mm) with exposed pad suits compact, thermally aware layouts in industrial or instrumentation designs.
Obsolete — sourcing through independent distribution
This part carries an Obsolete lifecycle status per the manufacturer.
8 MHz core and peripheral set for control-loop tasks
The 8 MHz clock rate is modest by modern MCU standards, but it aligns with the MSP430x4xx's ultra-low-power mission: the core draws microamps in standby while the integrated peripherals — brown-out detect, LCD driver, POR, PWM, and watchdog timer — handle housekeeping without waking the CPU. The 32 I/O lines and internal oscillator keep the external BOM lean for panel controllers, data loggers, or battery-backed instrumentation.
