For a 16-bit core this gives roughly 16 MIPS. The 60 KB Flash is organised as 60K x 8 plus 256 bytes of information memory (for calibration constants or unique IDs). The 2 KB RAM is tight: you will need to watch stack depth and buffer allocation. If your design streams data or holds large lookup tables, consider a sibling with more RAM. The Flash is field-programmable via the built-in bootstrap loader (BSL) or JTAG, so firmware updates are possible in-system. This part is end-of-life (EOL) per the manufacturer. That means it is in the last-time-buy window.","metaTitle":"TI MSP430F2491TRGCR 16-Bit MCU, 16MHz, 60KB Flash, 64-VQFN","metaDescription":"Texas Instruments MSP430F2491TRGCR 16-bit MCU, 16MHz, 60KB Flash, 2KB RAM, -40°C to 105°C, 64-VQFN.
