FRAM writes at bus speed with no erase cycle, so the 48 KB program memory can be updated in-system nearly as fast as RAM — useful for data-logging buffers, configuration tables, or OTA firmware patches where Flash write latency and endurance (typically 10k–100k cycles) are a constraint. The same memory serves as both code and data storage, simplifying the memory map. ## Package and footprint for the board designer Housed in a 38-TSSOP (6.10 mm body width, 0.240\" pitch), the MSP430FR5948IDAR is a surface-mount package suited for automated assembly. The 31 I/Os give enough headroom for a sensor interface, a small display, and a radio module without needing a larger package. Supply decoupling should follow the typical 0.1 µF + 1 µF ceramic per Vcc pin, placed close to the device. ## Sourcing posture and lifecycle For dual-sourcing resilience, the MSP430 FRAM family includes pin-compatible siblings with varying memory sizes; the base product number MSP430FR5948 identifies this specific 48 KB FRAM variant.","metaTitle":"Texas Instruments MSP430FR5948IDAR MCU, 16-bit, 16 MHz","metaDescription":"Texas Instruments MSP430FR5948IDAR 16-bit MCU with 48 KB FRAM, 2K x 8 RAM, 16 MHz, 31 I/O, 1.8V–3.6V, -40°C to 85°C, 38-TSSOP.
