256 KB FRAM — the differentiator in a 16 MHz 16-bit MCU
The MSP430FR5964IRGZR: 256 KB of FRAM program memory provides non-volatile storage with high write endurance.
The 48-VFQFN package with exposed pad aids thermal dissipation in compact layouts.
Peripherals and connectivity — what the on-chip blocks cover
The internal oscillator reduces external BOM count, though an external crystal can be used when tighter timing accuracy is needed.
For procurement, this simplifies supply planning: standard lead times apply through the independent distribution channel, and multi-source availability is typical for this volume-tier MCU. The base product number MSP430FR5964 covers the family, so density or package variants share the same supply chain profile.
