Active production, no EOL worry
No urgent need to qualify a replacement for new designs.
16 KB Flash, 512 bytes RAM — size the firmware early
Program memory is 16 KB of Flash with an additional 256 bytes for info storage; RAM is 512 x 8 (512 bytes). That is a modest memory footprint — fine for a dedicated LCD controller, sensor hub, or simple protocol bridge, but tight for a full RTOS or large data buffers. Plan the firmware image and stack usage before layout.
On-chip LCD driver saves a chip
The integrated LCD driver is the standout peripheral on this MSP430x4xx part. Combined with the 56 I/O lines, this MCU is well suited for instrument panels, metering displays, and portable medical readers.
8 MHz core — low power, not number-crunching
The CPU16 core runs at 8 MHz. That is not a speed demon — this is an ultra-low-power part designed for battery or energy-harvesting applications where every microamp counts.
Industrial temperature, surface-mount package
It comes in a 64-pin LQFP (10x10 mm body), a standard fine-pitch surface-mount package that reflows easily with a typical lead-free profile.
Supply range and I/O flexibility
The 56 I/O lines include peripherals like I²C, SPI, UART, IrDA, and LINbus — enough connectivity for sensor fusion, display control, and serial communication in a single chip.
