AI Summary

MSP-EXP430FR2433 by Texas Instruments: MSP430FR2433 LaunchPad™ MSP430FR2 MSP430 MCU 16-Bit Embedded Evaluation Board.

The MSP-EXP430FR5969 offers a step-up to the higher-performing MSP430FR5x FRAM family, providing a significant boost in non-volatile storage while keeping the same physical 20-pin LaunchPad footprint.

  • Significantly larger memory with 64 KB FRAM and 2 KB SRAM for more demanding applications
  • Dedicated ultra-low-power features and active EnergyTrace hardware monitoring on-board
  • Directly compatible with the standard 20-pin BoosterPack ecosystem
  • Higher initial board cost
  • Slightly different clock tree configuration and peripheral registers on the MSP430FR5969 MCU

The MSP-EXP430FR2355 is the most direct functional upgrade within the MSP430FR2x value line series, providing more memory and enhanced analog features while remaining fully compatible with the 20-pin BoosterPack ecosystem.

  • Larger memory capacity with 32 KB FRAM and 4 KB SRAM compared to 15.5 KB FRAM on the original
  • Includes high-performance integrated analog peripherals like four smart analog combos (op-amps/PGAs) and a 12-bit ADC/DAC
  • Maintains the standard 20-pin BoosterPack header form factor and includes an onboard eZ-FET debug probe with EnergyTrace
  • Upgraded internal analog blocks may require software initialization updates when porting code from MSP430FR2433

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
