The 16 MHz clock is fast enough for real-time control loops, sensor polling, and updating a segment LCD in a metering application. The FRAM program memory is the standout feature: it writes at near-SRAM speed and endures over 10¹⁵ write cycles, so firmware can log data directly to program space without wearing out the memory.
The 48-TSSOP package (6.10 mm body width) is a surface-mount footprint that fits compact two-layer boards without requiring fine-pitch assembly.
The supply voltage range is 1.8 V to 3.6 V.
Yes, it uses the standard MSP430 JTAG/SBW programming interface and is supported by TI's MSP430 tool chain.
The base product number MSP430FR4132 covers this variant; pin-compatible siblings with different FRAM and SRAM sizes exist in the MSP430FR413x family.
The CPU is clocked at 16 MHz.
