On-chip brown-out detect and POR eliminate the need for an external supervisor in most designs — the BOR holds the core in reset until the supply crosses the threshold, then the POR initialises the registers. The internal oscillator means no external crystal for the basic clock, though the UART baud rate accuracy depends on the internal DCO calibration. ## Active lifecycle — no LTB clock ticking The base product number MSP430F2491 carries the same flash and RAM map across the VQFN and TSSOP packages, so a board spin between packages is straightforward if the supply shifts. RoHS3 compliant per the manufacturer's declaration. ## Package and board-fit — the 64-VQFN exposed pad The 0.5 mm pitch demands a 4-layer board for reliable fan-out of the inner rows; a 2-layer board works only if the outer rows carry the critical signals and the inner rows are tied to power or ground. Tape & Reel packaging (TR) is the standard for automated pick-and-place; Cut Tape (CT) is also available for prototype quantities. The MSL rating is not stated in this listing — confirm the floor life before opening the reel if the bake history matters for your line.","metaTitle":"MSP430F2491TRGCT MCU, 16MHz, 60KB Flash, 64-VQFN","metaDescription":"Texas Instruments MSP430F2491TRGCT 16-bit MCU, 16MHz, 60KB Flash, 2KB RAM, 48 I/O, 1.8-3.6V, -40 to 105°C, 64-VQFN.
