Product details
Overview
MSP430FR5857IDA from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 32KB nonvolatile memory, 1KB RAM, and integrated 12-bit ADC (14 external + 2 internal 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 long-term retention without write endurance limits.
For engineers reviewing the MSP430FR5857IDA datasheet, MSP430FR5857IDA pinout, MSP430FR5857IDA application, or MSP430FR5857IDA equivalent, key selection criteria include HFXT oscillator support (not LFXT), TSSOP-38 package footprint, 31 GPIOs with capacitive touch capability, and FRAM's 1015 write-cycle endurance for frequent logging.
Technical Context
This device belongs to the MSP430FR585x series optimized for high-frequency crystal (HFXT) operation only-no LFXIN/LFXOUT pins-and excludes RTC_B functionality. Its CPUXV2 core runs at up to 16 MHz with seven low-power modes, including LPM3.5 (0.25 µA typical) enabled by the DCO+HFXT clock system.
The peripheral set includes two eUSCI_A modules (UART/IrDA/SPI), one eUSCI_B (I²C/SPI), five 16-bit timers (TA0–TA3, TB0), 32-bit hardware multiplier, 3-channel DMA, and 16-channel analog comparator-all mapped to 31 I/O pins in the 38-pin TSSOP package with full port interrupt and wake-from-LPM capability.
Key Specifications

Use Value: 32 KB FRAM stores ~2.5 million 16-bit samples; unified memory simplifies firmware design versus split flash/RAM architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5858IDA | 48 KB FRAM, 2 KB RAM-same package, clock system, and peripheral set | Higher memory headroom for larger firmware or extended buffer storage | Select when >32 KB program/data space is required without changing PCB layout |
| MSP430FR5847IDA | LFXT-only (LFXIN/LFXOUT), no HFXIN/HFXOUT pins; 32 KB FRAM, 1 KB RAM | Requires 32-kHz crystal for RTC; incompatible HFXT pinout and clock architecture | Choose only if 32-kHz crystal is preferred and HFXT support is unnecessary |
Compared with MSP430FR5858IDA, the MSP430FR5857IDA offers identical peripherals and power profiles but 16 KB less FRAM-sufficient for compact firmware with minimal logging. Against MSP430FR5847IDA, it trades LFXT dependency for HFXT flexibility, enabling crystal-free RTC operation and higher-frequency timing accuracy.

FAQ
What is the maximum operating frequency of the MSP430FR5857IDA?
The MSP430FR5857IDA supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO or external HFXT oscillator. This enables real-time signal processing and high-speed serial communication while maintaining ultra-low-power operation across all active and low-power modes.
Does the MSP430FR5857IDA support real-time clock functionality?
Yes, the MSP430FR5857IDA includes RTC_B module functionality, but it operates using the DCO and HFXT clock sources-not a 32-kHz crystal. The device achieves 0.25 µA typical current in LPM3.5 mode with calendar and alarm functions active, eliminating need for external LFXT components.
How many analog input channels does the MSP430FR5857IDA ADC support?
The MSP430FR5857IDA integrates a 12-bit ADC12_B module supporting 14 external analog input channels (A0–A15, excluding A6/A7) plus 2 internal channels (temperature sensor and VREF). All inputs are accessible through dedicated pins in the TSSOP-38 package with configurable sample-and-hold timing.
What communication interfaces are available on the MSP430FR5857IDA?
The MSP430FR5857IDA provides three enhanced universal serial communication interfaces: two eUSCI_A modules (supporting UART with auto-baud detection, IrDA, and SPI) and one eUSCI_B module (supporting I²C with multiple slave addressing and SPI). These are fully independent and can operate concurrently.
Is the MSP430FR5857IDA pin-compatible with other devices in the MSP430FR58xx family?
The MSP430FR5857IDA uses the 38-pin TSSOP (DA) package and shares identical pinout with MSP430FR5858IDA and MSP430FR5859IDA. However, it is not pin-compatible with RHA or RGZ packages, nor with LFXT-based variants like MSP430FR5847IDA due to differing oscillator pin allocations (HFXIN/HFXOUT vs LFXIN/LFXOUT).
