Product details
Overview
MSP430FR5848IDA from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 38-pin TSSOP package, featuring 48KB nonvolatile FRAM, 2KB RAM, 12-bit ADC with 12 external inputs, RTC with calendar/alarm, and dual eUSCI modules (UART/I²C/SPI). It operates from 1.8 V to 3.6 V and targets energy-constrained sensor nodes and data loggers.
For engineers reviewing the MSP430FR5848IDA datasheet, MSP430FR5848IDA pinout, MSP430FR5848IDA application, or MSP430FR5848IDA equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 current (0.25 µA typical), RTC support with LFXT, and TSSOP-38 footprint compatibility for space-constrained PCBs.
Technical Context
The MSP430FR5848IDA implements the MSP430 CPUXV2 core with 16 registers and integrates a flexible clock system including DCO, VLO, and LFXT (32-kHz crystal oscillator) - required for RTC_B operation. Its memory architecture unifies program, data, and storage in 48KB FRAM, eliminating erase cycles and enabling byte-level writes.
Peripherals include five 16-bit timers (TA0–TA3, TB0), 3-channel DMA, 16-channel comparator, hardware multiplier, CRC16 engine, and capacitive touch I/O on all pins. The device supports UART BSL via P2.0/P2.1 and lacks HFXT - confirmed by family documentation restricting HFXIN/HFXOUT to MSP430FR5x5x and MSP430FR5x6x variants only.

FAQ
What is the maximum operating frequency of the MSP430FR5848IDA?
The MSP430FR5848IDA supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO or external HFXT (though HFXT is not supported on this variant per family documentation). Its CPUXV2 core executes instructions at one cycle per instruction at this rate, enabling responsive real-time control without compromising ultra-low-power operation in active mode (~100 µA/MHz).
Does the MSP430FR5848IDA support hardware UART bootloading?
Yes, the MSP430FR5848IDA supports UART-based bootloader (BSL) using P2.0 (BSLTX) and P2.1 (BSLRX) pins. This allows field firmware updates without JTAG hardware, leveraging the integrated eUSCI_A0 module with automatic baud-rate detection - a key feature for remote or sealed-device maintenance scenarios involving the MSP430FR5848IDA.
Can the MSP430FR5848IDA operate without an external crystal?
The MSP430FR5848IDA can operate without an external crystal for general computing using its internal DCO or VLO clocks. However, RTC functionality and LPM3.5 mode require the 32-kHz LFXT crystal connected to PJ.4/LFXIN and PJ.5/LFXOUT - omission disables calendar/alarm features and increases standby current to LPM3 levels (0.4 µA).
How many ADC input channels does the MSP430FR5848IDA support?
The MSP430FR5848IDA supports 12 external analog input channels (A0–A11) plus 2 internal references, as confirmed in Table 3-1 of the datasheet. This matches the MSP430FR584x series specification and differs from the 14-channel variants (e.g., MSP430FR5849IDA); all 12 channels are accessible via dedicated pins including P1.0–P1.5, P3.0–P3.3, and P4.0–P4.1 on the MSP430FR5848IDA.
Is the MSP430FR5848IDA pin-compatible with other MSP430FR584x devices in TSSOP-38?
Yes, the MSP430FR5848IDA shares identical pinout and package (TSSOP-38) with MSP430FR5847IDA and MSP430FR5849IDA, as verified in Figures 4-3 and 4-5 of the datasheet. All three variants use the same terminal numbering and signal mapping - enabling drop-in replacement during design iteration or volume manufacturing without PCB changes.
