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.","metaTitle":"Texas Instruments MSP430G2855IRHA40T 16-bit MCU, 48KB Flash","metaDescription":"MSP430G2855IRHA40T 16-bit MCU with 48KB Flash, 4KB RAM, 16 MHz, 32 I/O, I²C/SPI/UART, 1.8-3.6V, -40 to 85°C, 40-VQFN.
