The 60 KB Flash (organized as 60K x 8 plus 256 bytes) is typical for the MSP430x1xx mid-range and gives room for a modest RTOS, sensor fusion libraries, and communication stacks. The 2 KB RAM handles small data buffers and stack frames; designs that need larger packet buffers or data logging should budget for external SPI SRAM or move up the MSP430 family. The on-chip Slope A/D converter handles slow analog inputs without an external ADC, saving BOM cost. ## Peripherals and connectivity for sensor and control applications On-chip peripherals include POR (power-on reset), PWM outputs, and a watchdog timer. Serial connectivity covers SPI and UART/USART, enough to interface with common sensors, radios, and serial displays. The 48 I/O pins provide headroom for parallel LCD interfaces, keypad matrices, or multiple external interrupts. ## Package and footprint — 64-VFQFN with exposed pad Housed in a 64-VFQFN Exposed Pad package (supplier package 64-VQFN 9x9 mm), this is a surface-mount device.","metaTitle":"Texas Instruments MSP430F1491IRTDR 16-bit MCU, 8MHz","metaDescription":"MSP430F1491IRTDR 16-bit MCU from TI MSP430x1xx series. 8MHz core, 60KB Flash, 2KB RAM, 48 I/O, 1.8V-3.6V supply.
