Product details

The 48 KB Flash (48K x 8) is generous for a 16-bit MCU in this tier — enough for a modest RTOS, a communication stack (I²C, SPI, UART are all on-chip), and application logic. The 4 KB RAM (4K x 8) is the tighter resource: it limits buffering for high-rate sensor data or large protocol frames.

The wide supply range lets the MSP430G2855IRHA40T run directly from two alkaline cells (down to 1.8 V) or a regulated 3.3 V rail. For a battery-powered design, this means one less component and a lower BOM count.

40-VQFN package — footprint and thermal considerations

The 40-VFQFN with exposed pad (6x6 mm body) is a compact surface-mount package.

It is ROHS3 compliant.
