Product details
Overview
MSP430FR5848IDAR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 48KB nonvolatile memory, 2KB RAM, and integrated 12-bit ADC (14 external channels), RTC, and dual eUSCI modules (UART/I²C/SPI). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and data loggers requiring sub-µA LPM3.5 operation (0.25 µA typical).
For engineers reviewing the MSP430FR5848IDAR datasheet, MSP430FR5848IDAR pinout, MSP430FR5848IDAR application, or MSP430FR5848IDAR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), capacitive touch I/O support, LFXT-based RTC capability, and TSSOP-38 package compatibility with energy-harvesting power budgets.
Technical Context
The MSP430FR5848IDAR implements the CPUXV2 core with 16 registers and executes instructions at up to 16 MHz using a factory-trimmed DCO or external 32-kHz LFXT crystal. Its low-power architecture supports seven operating modes, including LPM3.5 (RTC active, 0.25 µA) and LPM4.5 (shutdown, 0.02 µA), enabled by SVS brownout protection and programmable port pullups/pulldowns.
Peripherals include a 32-bit hardware multiplier, three-channel DMA, five 16-bit timers (TA0–TA3, TB0), 16-channel analog comparator, and eUSCI_A0/A1 (UART/IrDA/SPI) plus eUSCI_B0 (I²C/SPI). The device lacks HFXT support and uses only LFXT for RTC functionality, per TI's functional block diagram and device comparison table.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5847IDAR | 32 KB FRAM, 1 KB RAM, same TSSOP-38 package and peripheral set | Lower memory capacity limits long-term data retention in high-frequency logging | Select when application requires <32 KB program+data space and cost sensitivity outweighs memory headroom |
| MSP430FR5849IPNR | 64 KB FRAM, 2 KB RAM, VQFN-40 package (6 mm × 6 mm), adds HFXIN/HFXOUT pins | HFXT support enables higher-speed communication but increases layout complexity and power in LF-only designs | Choose for space-constrained PCBs needing more FRAM and optional HF clock flexibility |
Compared with MSP430FR5847IDAR, the MSP430FR5848IDAR provides +16 KB FRAM for extended data buffering without increasing package size; versus MSP430FR5849IPNR, it eliminates HFXT pins to simplify crystal routing and reduce BOM count in pure-LFXT RTC applications.

FAQ
What is the maximum operating frequency of the MSP430FR5848IDAR?
The MSP430FR5848IDAR supports a maximum system clock frequency of 16 MHz, achieved using the factory-trimmed DCO oscillator or an external high-frequency crystal. This allows real-time signal processing and responsive peripheral handling while maintaining ultra-low-power efficiency across all operating modes.
Does the MSP430FR5848IDAR support hardware encryption or secure boot?
No, the MSP430FR5848IDAR does not include AES hardware acceleration or secure boot features. It provides a random number seed generator for software-based cryptographic primitives but relies on external security elements or firmware-level protections for key management and code integrity verification.
Can the MSP430FR5848IDAR operate without an external crystal?
Yes, the MSP430FR5848IDAR can operate using its internal digitally controlled oscillator (DCO) across the full 1.8–3.6 V range. However, the RTC_B module requires a 32-kHz LFXT crystal (e.g., 3.7-pF load) for calendar and alarm functionality - the DCO alone cannot meet RTC accuracy requirements.
What is the pin count and package type of the MSP430FR5848IDAR?
The MSP430FR5848IDAR uses a 38-pin TSSOP package (orderable code IDAR), with dimensions of 12.5 mm × 6.2 mm and 0.65 mm lead pitch. It includes dedicated analog inputs (A0–A9, A12–A15), timer-capable pins, and dual eUSCI interfaces mapped across its GPIO bank.
How does FRAM endurance compare to flash in the MSP430FR5848IDAR?
The MSP430FR5848IDAR's 48 KB FRAM offers 10¹⁵ write cycles - orders of magnitude higher than typical flash (10⁴–10⁵ cycles). This enables frequent data logging without wear leveling, eliminates erase-before-write latency, and supports true EEPROM-like byte-level writes with no block constraints.
