Description

MSP430FR5849IRHAR is TI’s MSP430 microcontroller from the FR58x family. It uses a 16-bit MSP430 CPU with on‑chip FRAM (ferroelectric RAM) for nonvolatile memory, enabling fast writes and low-energy operation without a separate flash.
Key points:
- Memory: FRAM for program/data plus on‑chip SRAM; saves energy with rapid nonvolatile updates.
- Peripherals: timers, a 12‑bit ADC, DMA, eUSCI (UART/SPI/I2C), LCD driver, comparators, watchdog, and capacitive‑touch support.
- Power: ultra‑low power with multiple low‑power modes and fast wake‑up; operates from ~1.8–3.6 V.
- Packaging: industrial-temp variants in common 48-pin packages (and other options).
- Applications: portable sensors, battery-powered instruments, human–machine interfaces, data logging.
- Development: Code Composer Studio or IAR; MSP430Ware HAL and example libraries.
Note: exact memory size, peripheral counts, and temperature/package options vary by variant. Check the MSP430FR5849IRHAR datasheet/product folder for precise specifications.

- Supply voltage 1.8–3.6 V; CPU clock up to ~16 MHz; 32 kHz crystal support for RTC.
- Ultra-low power with multiple low‑power modes and rapid wake-up.
- On-chip peripherals:
- ADC12: 12‑bit ADC with multiple channels and internal reference
- Timers: multiple 16‑bit Timer_A and Timer_B modules plus RTC
- Serial: eUSCI A/B for UART, SPI, I2C
- DMA controller for efficient data transfers
- Analog comparators
- Memory: substantial FRAM plus RAM for code and data
- Debug/Programming: on-card debugging interface
- Package: 48‑pin (IRHAR) package option (QFN/LQFP)
- Temperature range: typical industrial range (-40°C to 85°C)
Ideal for ultra-low‑power sensing, instrumentation and embedded control with fast nonvolatile memory.
