Product details
Overview
MSP430FR5848IRHAT 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 metering systems requiring long-term data retention without write endurance limits.
For engineers reviewing the MSP430FR5848IRHAT datasheet, MSP430FR5848IRHAT pinout, MSP430FR5848IRHAT application, or MSP430FR5848IRHAT equivalent, key selection criteria include its LFXT-only clock architecture, 40-pin VQFN (RHA) package, 0.25 µA RTC mode current, FRAM write speed (125 ns/word), and capacitive touch I/O support across all pins - critical for energy-harvested wearable and industrial logging designs.
Technical Context
The MSP430FR5848IRHAT implements the MSP430 CPUXV2 core with 16 registers and executes instructions at up to 16 MHz using a factory-trimmed DCO or 32-kHz LFXT crystal. Its low-power architecture supports seven LPMs, 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 (UART/IrDA/SPI) + eUSCI_B0 (I²C/SPI), with BSL supporting UART-based firmware updates via P2.0/P2.1. The device lacks HFXT and HFXIN/HFXOUT pins - confirmed by RHA package pinout and family documentation.

FAQ
What is the maximum operating frequency of the MSP430FR5848IRHAT?
The MSP430FR5848IRHAT supports a maximum system clock frequency of 16 MHz, achieved using the factory-trimmed DCO oscillator or an external high-frequency crystal. Its CPUXV2 core executes instructions at this rate while maintaining ultra-low active-mode current of approximately 100 µA/MHz - making it suitable for real-time signal processing in power-sensitive applications.
Does the MSP430FR5848IRHAT support high-frequency crystal oscillators (HFXT)?
No, the MSP430FR5848IRHAT does not support HFXT. It is part of the MSP430FR584x series, which is explicitly LFXT-only per TI's device comparison table and pin diagrams. Pins PJ.6/HFXIN and PJ.7/HFXOUT are absent in the RHA package; only PJ.4/LFXIN and PJ.5/LFXOUT are present for 32-kHz crystal connection.
How many analog input channels does the ADC on the MSP430FR5848IRHAT support?
The MSP430FR5848IRHAT integrates a 12-bit ADC12_B module with 14 external analog input channels (A0–A13) plus two internal references. This configuration is confirmed in Table 3-1 of the datasheet and matches the device's "14 ext, 2 int ch." specification - sufficient for multi-sensor monitoring without external multiplexers.
What debug interface does the MSP430FR5848IRHAT use?
The MSP430FR5848IRHAT uses the Spy-Bi-Wire (SBW) interface for debugging and programming, accessible via TEST/SBWTCK (pin 23) and RST/NMI/SBWTDIO (pin 24). This 2-wire JTAG variant reduces PCB footprint versus full 4-wire JTAG and is supported by TI's MSP-FET and LaunchPad development tools.
Is the MSP430FR5848IRHAT pin-compatible with other devices in the MSP430FR58xx family?
The MSP430FR5848IRHAT is pin-compatible with other 40-pin RHA variants in the MSP430FR584x series (e.g., MSP430FR5847IRHAT, MSP430FR5849IRHAT) but not with RGZ (48-pin) or DA (38-pin) packages. Pin functions match across RHA devices, enabling shared PCB layouts when memory requirements vary within the same package footprint.
