Product details

FRAM memory — why it changes the BOM calculus

That means you can log sensor data or store calibration constants directly in program space without wearing out sectors — no EEPROM emulation or external serial memory needed. The 10-channel 12-bit ADC and four 12-bit DAC channels handle analog front-end tasks on-chip, reducing external component count for closed-loop control or multi-sensor acquisition.

Connectivity and peripherals — what is on the bus

TI lists the MSP430FR2355TDBT as Active. The base product number MSP430FR2355 indicates a family with multiple density and package variants, so if a future redesign needs more memory or a different footprint, there is a pin-compatible migration path within the same series without a PCB respin.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430FR2355TDBT in this component family?

Within the MSP430FR2355 series, devices with the same 38-TSSOP footprint and pinout — such as the MSP430FR2355TPT — share the same package and peripheral set. For a higher memory tier, the MSP430FR2355 family includes 64 KB FRAM variants in the same package, offering a drop-in upgrade path without PCB changes.

What is MSP430FR2355TDBT's listed speed (24MHz) on this component line?

The core processor runs at 24 MHz, which is sufficient for real-time control loops, sensor fusion, and data logging at moderate throughput. For higher-speed DSP or video processing, a Cortex-M4 or dedicated DSP would be a better fit.
