MSP430FR68221IG56R is a 64 KB FRAM, 16-bit MSP430 microcontroller in a 56-pin TSSOP package with I2C bootloader support and integrated analog, LCD, timing, and serial peripherals.

Best for

  • Low-power metering and sensing systems
  • Segment-LCD instrument interfaces
  • Battery-powered embedded control

Avoid if

  • Applications requiring more than 64 KB nonvolatile program memory
  • Designs requiring high-frequency crystal support on this FR682x variant
  • Systems requiring operation beyond the specified -40 °C to 85 °C range

Check before use

  • Confirm package-specific peripheral pin assignments
  • Configure FRAM wait states for MCLK above 8 MHz
  • Validate external crystal load capacitors and PCB layout if using LFXT
