It carries 16 KB of FRAM program memory and 1 KB of SRAM, with 32 general-purpose I/O lines. The FRAM technology unifies code and data storage in a single non-volatile memory that writes at bus speed with near-zero standby power — a practical advantage over Flash for frequent data logging or field-update scenarios.
Brown-out detect and POR are integrated, reducing external supervision components.
On-chip peripherals include I²C, SPI, UART/USART with LIN and IrDA support, plus a PWM timer and watchdog.
That means it remains available for existing production runs but is not intended for new project starts. For a new BOM, look at the current MSP430FR2xxx or MSP430FR5xxx family members in the same 40-VQFN footprint — TI's FRAM portfolio offers pin-compatible upgrades with more memory and higher speed.
