Product details
Overview
MSP430FR5848IRHAR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 48KB nonvolatile memory, 2KB RAM, 12-bit ADC (14 external channels), RTC clocked by 3.7-pF crystal, and integrated capacitive touch I/O-designed for energy-harvested sensor nodes and wearable electronics requiring long battery life and robust data retention.
For engineers reviewing the MSP430FR5848IRHAR datasheet, MSP430FR5848IRHAR pinout, MSP430FR5848IRHAR application, or MSP430FR5848IRHAR equivalent, key selection criteria include LPM3.5 current (0.25 µA), FRAM endurance (10¹⁵ writes), UART/I²C eUSCI peripherals, LFXT-only clock support, and 40-pin VQFN (RHA) package compatibility with space-constrained embedded designs.
Technical Context
The MSP430FR5848IRHAR implements the ULP CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.02 µA). Its FRAM memory replaces flash and EEPROM, enabling fast 125-ns word writes and unified program/data/storage space without erase cycles.
It integrates dual eUSCI modules: eUSCI_A0 supports UART with auto-baud detection and SPI; eUSCI_B0 supports I²C (multiple slave addressing) and SPI. The device lacks HFXT and HFXIN/HFXOUT pins-only LFXT (LFXIN/LFXOUT) is supported per its RHA package configuration and family specification.

FAQ
What is the maximum operating frequency of the MSP430FR5848IRHAR?
The MSP430FR5848IRHAR supports a maximum system clock frequency of 16 MHz via its factory-trimmed DCO oscillator. This allows deterministic real-time execution of control loops and signal processing tasks while maintaining ultra-low-power operation across all active and low-power modes. The MSP430FR5848IRHAR does not support external HFXT crystals-its clock system is limited to DCO and LFXT only.
Does the MSP430FR5848IRHAR support hardware encryption or secure boot?
The MSP430FR5848IRHAR does not include AES hardware acceleration or secure boot functionality. It features a Memory Protection Unit (MPU) with IP encapsulation for basic code/data isolation and a random number seed generator for software-based cryptographic primitives. For applications requiring certified security, external secure elements or higher-tier MSP430FR59xx devices with AES-128 modules should be evaluated instead of the MSP430FR5848IRHAR.
Can the MSP430FR5848IRHAR operate without an external crystal?
Yes-the MSP430FR5848IRHAR can operate using its internal DCO or VLO oscillators without any external crystal. However, the RTC_B module requires the 32-kHz LFXT crystal (connected to PJ.4/LFXIN and PJ.5/LFXOUT) to function. If RTC functionality is not needed, the MSP430FR5848IRHAR achieves full operation-including ADC, timers, and eUSCI peripherals-with no external timing components.
How many ADC input channels does the MSP430FR5848IRHAR support?
The MSP430FR5848IRHAR integrates a 12-bit ADC12_B module supporting up to 14 external analog input channels (A0–A13) plus two internal references. Channel mapping includes P1.0–P1.5, P3.0–P3.3, P1.3, P1.4, P1.5, P4.0, P4.1, and P2.3–P2.4-totaling 14 distinct external inputs as confirmed in the device comparison table and signal descriptions. This enables simultaneous multi-sensor acquisition in compact designs.
Is the MSP430FR5848IRHAR pin-compatible with other MSP430FR58xx RHA-package devices?
Yes-the MSP430FR5848IRHAR shares identical pinout, package dimensions, and signal assignments with MSP430FR5847IRHAR, MSP430FR5849IRHAR, and MSP430FR58471IRHAR in the 40-pin RHA package. All share the same VQFN-40 footprint, thermal pad connection requirement, and pin multiplexing scheme. Firmware and PCB layout are interchangeable across these variants, differing only in FRAM/RAM size and BSL protocol (UART vs. I²C).
