Product details

16 MHz — what the clock speed means for the design

The 16 MHz clock is the CPU's maximum operating frequency. For a 16-bit core this gives roughly 16 MIPS.

Memory sizing: 60 KB Flash, 2 KB RAM

The 60 KB Flash is organised as 60K x 8 plus 256 bytes of information memory (for calibration constants or unique IDs). That is enough for a moderate firmware image — a bootloader, a real-time operating system like FreeRTOS (with care), and a few hundred lines of application code. 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.

Lifecycle and sourcing

This part is end-of-life (EOL) per the manufacturer. That means it is in the last-time-buy window.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430F2491TRGCR in this component family?

The MSP430F2491TPM is a pin-compatible alternative in the same MSP430F2xx family. Verify Flash and RAM sizing against your firmware image before switching.

What is MSP430F2491TRGCR's listed speed (16MHz) on this component line?

The core runs at 16 MHz maximum, giving roughly 16 MIPS throughput for the 16-bit MSP430 CPU16.
