MSP430FR5949IRHAR

The MSP430FR5949IRHAR is a low-power, mixed-signal microcontroller from Texas Instruments, part of the MSP430 FRAM family. It features:
- 16-bit RISC CPU (up to 16 MHz)
- 64KB FRAM (non-volatile, fast-write memory)
- 2KB SRAM
- Ultra-low power consumption (as low as 100 µA/MHz active, 0.4 µA standby)
- Integrated peripherals: 12-bit ADC, comparators, timers, UART/SPI/I2C, and capacitive touch sensing
- Enhanced security with AES accelerator
- Package: 40-pin VQFN (RHA)
Ideal for battery-powered, energy-efficient applications like IoT sensors, wearables, and industrial monitoring. FRAM offers high endurance (10^15 cycles) and near-instant writes, improving reliability and speed over flash-based MCUs.
