Its program memory is 16 KB of FRAM — a non-volatile memory that writes at near-SRAM speed with 10^15 cycle endurance, so you can treat it like a unified memory for code and data without worrying about wear-leveling or write delays. The 1 KB SRAM handles stack and scratchpad. This combination suits applications that need frequent data logging, field firmware updates, or a single-chip bill of materials without external EEPROM. The 14-channel 10-bit ADC, along with I²C, SPI, UART, IrDA, and LINbus interfaces, gives it the peripheral mix for sensor fusion, industrial control, and low-power wireless nodes.

Frequently asked questions
What is the maximum clock frequency of MSP430FR5739IRHAR?
The MSP430 CPUXV2 core runs at 24 MHz. At that speed the FRAM can be read with zero wait states for most instructions, keeping the execution pipeline full without the flash wait-state penalty typical of other MCUs.
