Product details
Overview
MSP430FR2153TRSMT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 16KB FRAM, 2KB RAM, and integrated 12-bit SAR ADC (200 ksps), dual enhanced comparators, and two eUSCI_A/eUSCI_B modules supporting UART/I²C/SPI - designed for battery-powered industrial sensor nodes and smoke detectors operating from –40°C to 105°C.
For engineers reviewing the MSP430FR2153TRSMT datasheet, MSP430FR2153TRSMT pinout, MSP430FR2153TRSMT application, or MSP430FR2153TRSMT equivalent, key selection criteria include LPM3.5 current (620 nA), FRAM endurance (10¹⁵ writes), 32-pin VQFN package compatibility, and support for smart analog signal conditioning in safety-critical sensing systems.
Technical Context
The MSP430FR2153TRSMT implements a 24-MHz digitally controlled oscillator (DCO) with FLL, ±1% accuracy at room temperature, and supports multiple clock sources including internal REFO (32 kHz), VLO (10 kHz), MODOSC, and external crystals up to 24 MHz. Its power management module enables rapid wake-up (<10 µs) from LPM3.5 and includes SVS with configurable thresholds.
It integrates three Timer_B3 modules (each with 3 capture/compare registers) and one Timer_B7 (7 registers), CRC16 hardware, 32-bit MPY32 multiplier, and interrupt compare controller (ICC) for nested hardware interrupts - all operating within a unified FRAM memory space shared across program, constants, and data storage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2153TPT | 48-pin LQFP package (7 mm × 7 mm); same FRAM/RAM/ADC/peripheral set but larger footprint and higher I/O count (44 vs. 28). | Preferred where board space allows and additional GPIOs or routing flexibility are needed for complex sensor interfaces. | Select TPT for prototyping or designs requiring maximum pin availability; TRSMT for space-constrained PCBs. |
| MSP430FR2353TRSMT | Same 32-pin RSM package but adds four Smart Analog Combo (SAC) modules - configurable as PGA, OA, or 12-bit DAC - not present on FR2153. | Required when analog signal chain integration (e.g., programmable gain amplification before ADC) is needed without external components. | Choose FR2353TRSMT only if SAC functionality is essential; otherwise FR2153TRSMT offers lower cost and identical core MCU features. |
Compared with MSP430FR2153TPT, the MSP430FR2153TRSMT delivers identical MCU functionality in a 44% smaller footprint (4 mm² vs. 49 mm²), while the MSP430FR2353TRSMT adds SAC-based analog flexibility at higher unit cost - making the MSP430FR2153TRSMT optimal for compact, cost-sensitive, FRAM-based sensing nodes without advanced analog front-end needs.

FAQ
What is the maximum operating frequency of the MSP430FR2153TRSMT?
The MSP430FR2153TRSMT supports a maximum CPU clock frequency of 24 MHz via its digitally controlled oscillator (DCO) with frequency-locked loop (FLL). This speed is achievable across the full operating voltage range (1.8 V to 3.6 V) and temperature range (–40°C to 105°C), enabling real-time signal processing in demanding sensor applications while maintaining ultra-low-power efficiency.
Does the MSP430FR2153TRSMT include Smart Analog Combo (SAC) modules?
No, the MSP430FR2153TRSMT does not include Smart Analog Combo (SAC) modules. SAC functionality is exclusive to the MSP430FR235x family. The MSP430FR2153TRSMT provides two enhanced comparators (eCOMP) with integrated 6-bit DAC references and rail-to-rail operation, but lacks the configurable PGA, OA, and DAC combinations found in SAC-enabled variants.
What are the supported low-power modes and their typical currents for MSP430FR2153TRSMT?
The MSP430FR2153TRSMT supports six low-power modes. Key values include: LPM3 with 32-kHz crystal draws 1.43 µA (SVS enabled); LPM3.5 draws 620 nA (32-kHz crystal active, SVS enabled); and LPM4.5 (shutdown) draws 42 nA (SVS disabled). These values are measured at 3 V and 25°C per SLASEC4D datasheet Section 5.8.
Can the MSP430FR2153TRSMT operate from a 1.8-V supply?
Yes, the MSP430FR2153TRSMT operates from 1.8 V to 3.6 V. However, functional voltage limits depend on SVS thresholds - the device may enter reset below VSVSH− (typically 1.71 V min) unless SVS is disabled. At 1.8 V, maximum CPU frequency is reduced to ~8 MHz, and peripheral availability (e.g., ADC accuracy) must be verified per Section 5.3 of the datasheet.
What debug interface does the MSP430FR2153TRSMT support?
The MSP430FR2153TRSMT supports Spy-Bi-Wire (SBW) debug interface using two pins: TEST/SBWTCK (pin 6) and RST/NMI/SBWTDIO (pin 7). This 2-wire interface enables full programming, debugging, and real-time trace capabilities - compatible with TI's MSP-FET and LaunchPad debug probes - without requiring full 4-pin JTAG.
