Product details
Overview
MSP430FR2153TRHAR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 16KB FRAM, 2KB RAM, and integrated 12-bit ADC (10-channel), two enhanced comparators, and dual eUSCI_A/eUSCI_B modules for UART/I²C/SPI. It operates from 1.8 V to 3.6 V across –40°C to 105°C and targets battery-powered industrial sensing applications such as smoke detectors and sensor transmitters.
For engineers reviewing the MSP430FR2153TRHAR datasheet, MSP430FR2153TRHAR pinout, MSP430FR2153TRHAR application, or MSP430FR2153TRHAR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 current (620 nA), 40-pin VQFN package compatibility, and support for smart analog signal conditioning without external op-amps.
Technical Context
The MSP430FR2153TRHAR implements a 24-MHz digitally controlled oscillator (DCO) with FLL, ±1% accuracy at room temperature, and supports multiple clock sources including internal REFO/VLO/MODOSC and external LFXT/HFXT. Its power management module enables rapid wake-up (<10 µs) from LPM3.5 and includes SVS with configurable thresholds.
It integrates a unified memory architecture where FRAM serves program, constants, and data storage, backed by 20KB ROM with driver and FFT libraries. The device lacks Smart Analog Combo (SAC) modules - distinguishing it from MSP430FR235x variants - and uses only standard analog peripherals: 12-bit SAR ADC, two eCOMPs with 6-bit DAC reference, and programmable hysteresis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2153TRSMR | 32-pin VQFN (RSM) package, 28 GPIO, 8 ADC channels; same FRAM/RAM/temperature specs. | Smaller PCB footprint and lower I/O count; suitable for space-constrained, lower-channel-count sensor nodes. | Select when board area is critical and ≤28 GPIO + 8 ADC channels suffice; verify pin mapping differs significantly from RHA. |
| MSP430FR2353TRHAR | Same 40-pin RHA package and pinout, but adds four Smart Analog Combo (SAC-L3) modules - configurable OA/PGA/DAC - and increases ADC to 12 channels. | Enables analog signal chain integration (e.g., programmable-gain amplification before ADC), reducing external components in precision sensor interfaces. | Choose when SAC functionality is needed; note SAC modules are absent in MSP430FR2153TRHAR and not software-compatible. |
Compared with MSP430FR2153TRHAR, the TRSMR offers smaller size but fewer I/Os and ADC channels, while the FR2353TRHAR provides identical packaging and pin compatibility plus integrated analog signal-chain flexibility - making it a functional upgrade path where SAC usage justifies cost and firmware changes.

FAQ
What is the maximum operating frequency of the MSP430FR2153TRHAR?
The MSP430FR2153TRHAR 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, with ±1% accuracy at room temperature using the on-chip reference. The MSP430FR2153TRHAR does not require external crystals for high-speed operation but supports them for precision timing.
Does the MSP430FR2153TRHAR include Smart Analog Combo (SAC) modules?
No, the MSP430FR2153TRHAR does not include Smart Analog Combo (SAC) modules. SAC-L3 units are exclusive to the MSP430FR235x family (e.g., MSP430FR2353TRHAR). The MSP430FR2153TRHAR provides only standard analog peripherals: a 12-bit SAR ADC with 10 channels, two enhanced comparators (eCOMP) with 6-bit DAC reference, and programmable hysteresis - sufficient for basic analog monitoring but not configurable op-amp or PGA functions.
What debug interface does the MSP430FR2153TRHAR support?
The MSP430FR2153TRHAR supports the Spy-Bi-Wire (SBW) interface using two pins: SBWTDIO and SBWTCK. This 2-wire debug protocol is fully compatible with TI's MSP-FET debugger, LaunchPad development kits (e.g., MSP-EXP430FR2355), and Code Composer Studio IDE. It enables full flash programming, real-time debugging, and boundary-scan without requiring a 4-wire JTAG connection.
How many I²C interfaces does the MSP430FR2153TRHAR have, and which pins are used?
The MSP430FR2153TRHAR includes two independent eUSCI_B modules supporting I²C: eUSCI_B0 and eUSCI_B1. eUSCI_B0 uses P1.3 (UCB0SOMI/UCB0SCL) for SCL/SDA, while eUSCI_B1 uses P4.7 (UCB1SOMI/UCB1SCL). Both support master and slave modes, enabling dual-sensor I²C buses - for example, one for environmental sensors and another for EEPROM or display control - without bit-banging.
What is the FRAM endurance specification for the MSP430FR2153TRHAR?
The MSP430FR2153TRHAR specifies 10¹⁵ write cycles for its FRAM memory - orders of magnitude higher than flash or EEPROM. This endurance applies to all 16KB of program/data FRAM and 512B of dedicated data FRAM. Unlike flash, FRAM writes are byte-addressable, instantaneous (<100 ns), and do not require erase cycles, making it ideal for high-frequency data logging in applications like battery pack monitoring or sensor event timestamps.
