Product details
Overview
MSP430FR2153TRSMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 16KB program FRAM, 512B data FRAM, and 2KB RAM, operating from 1.8 V to 3.6 V across –40°C to 105°C. It integrates a 12-bit SAR ADC (200 ksps), two enhanced comparators with 6-bit DAC reference, dual eUSCI_A (UART/IrDA/SPI) and dual eUSCI_B (SPI/I²C), and three Timer_B3 modules - used in battery-powered smoke detectors and industrial sensor transmitters.
For engineers reviewing the MSP430FR2153TRSMR datasheet, MSP430FR2153TRSMR pinout, MSP430FR2153TRSMR application, or MSP430FR2153TRSMR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 current (620 nA), 32-pin VQFN package footprint, and integrated analog signal-chain capability for sensor conditioning without external op-amps.
Technical Context
The MSP430FR2153TRSMR implements a 16-bit RISC CPU with 24-MHz DCO+FLL clock system, ±1% accuracy at room temperature, and sub-10 µs wake-up from LPM3. Its memory architecture unifies FRAM for code, constants, and data storage with built-in ECC and configurable write protection.
Analog subsystem includes a 12-channel 12-bit ADC with internal 1.5/2.0/2.5 V references, two eCOMP modules (one with 100-ns response, one with 1.5-µA low-power mode), and no Smart Analog Combo (SAC) modules - distinguishing it from MSP430FR235x variants. Digital peripherals include CRC16, MPY32, ICC, RTC counter, and Manchester codec (MFM).

Applications
| Smoke and Heat Detectors | Sensor Transmitters |
|---|---|
Use Scenario: Standalone battery-powered detector monitoring ambient temperature and smoke particle density via optical/thermal sensors. IC Role / Device Role / Timing Role: Main controller executing sensor readout, alarm logic, and wireless wake-up signaling; RTC maintains time-stamped event logs in FRAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2153TRHA | 40-pin VQFN package; adds 8 more GPIOs (36 total) and 2 additional ADC channels (10 vs. 8 in RSM). | Preferred where board space allows larger package and higher I/O count is needed for multi-sensor interfacing. | Select when needing extra analog inputs or GPIOs without changing core firmware - same FRAM size, RAM, and peripheral set. |
| MSP430FR2111TRSMR | Lower memory: 2KB FRAM, 512B RAM; no eUSCI_B (I²C/SPI), only one eUSCI_A; 8-channel ADC. | Suitable for simpler, lower-cost endpoints where I²C connectivity and high channel count are unnecessary. | Choose for ultra-low-cost sensor nodes with minimal communication and storage requirements - shares same 32-pin RSM footprint. |
Compared with MSP430FR2153TRHA, the MSP430FR2153TRSMR saves PCB area and component count in space-constrained designs; versus MSP430FR2111TRSMR, it delivers 8× more FRAM and full dual-protocol serial support - essential for field-upgradable sensor firmware and multi-interface gateways.

FAQ
What is the maximum operating frequency of the MSP430FR2153TRSMR?
The MSP430FR2153TRSMR features a digitally controlled oscillator (DCO) with frequency-locked loop (FLL) supporting up to 24 MHz operation. This maximum frequency is achievable across the full –40°C to 105°C temperature range and 1.8 V to 3.6 V supply voltage, with ±1% accuracy at room temperature using the on-chip reference. The MSP430FR2153TRSMR's clock system also includes programmable prescalers for MCLK and SMCLK to optimize peripheral timing without sacrificing CPU performance.
Does the MSP430FR2153TRSMR include Smart Analog Combo (SAC) modules?
No, the MSP430FR2153TRSMR does not include Smart Analog Combo (SAC) modules. SAC functionality is exclusive to the MSP430FR235x family (e.g., MSP430FR2353). The MSP430FR2153TRSMR provides two enhanced comparators (eCOMP0/eCOMP1) and a 12-bit SAR ADC but lacks the configurable op-amp, PGA, and DAC combinations found in SAC blocks. This distinction is confirmed in the device comparison table and functional block diagrams of the MSP430FR215x datasheet.
What are the supported serial communication protocols on the MSP430FR2153TRSMR?
The MSP430FR2153TRSMR supports UART, IrDA, and SPI via two eUSCI_A modules (eUSCI_A0 and eUSCI_A1), and SPI and I²C via two eUSCI_B modules (eUSCI_B0 and eUSCI_B1). Notably, eUSCI_B1 supports I²C only - a documented limitation per the device comparison table. All interfaces are software-configurable and share GPIO pins through port multiplexing, allowing flexible routing without hardware redesign.
How much FRAM and RAM does the MSP430FR2153TRSMR have?
The MSP430FR2153TRSMR contains 16KB of program FRAM, 512B of data FRAM, and 2KB of RAM. This memory configuration is explicitly listed in the "Family members" section and verified in Table 3-1 (Device Comparison) of the datasheet. The unified FRAM architecture allows seamless allocation of code, constants, and runtime variables within the same nonvolatile memory space, while the 2KB RAM serves as high-speed buffer for active computation and peripheral FIFOs.
Is the MSP430FR2153TRSMR qualified for extended temperature operation?
Yes, the MSP430FR2153TRSMR is fully qualified for operation from –40°C to 105°C ambient temperature. This extended range is specified in the Device Information table and reinforced in the Applications section, which cites smoke detectors, circuit breakers, and industrial sensor transmitters as target use cases. The qualification covers all electrical specifications, including LPM3.5 current (620 nA), ADC performance, and FRAM reliability - making it suitable for deployment in thermally demanding enclosures and outdoor industrial environments.
