Product details
Overview
MSP430FR2353TRHAR 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 four Smart Analog Combo (SAC-L3) modules, a 12-bit 200 ksps ADC, two enhanced comparators, dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (SPI/I²C) interfaces, and supports LPM3.5 standby at 620 nA.

Technical Context
The MSP430FR2353TRHAR implements a 16-bit RISC CPU with 24-MHz DCO+FLL clock system, ±1% accuracy at room temperature, and fast wake-up (<10 µs) from LPMs. Its memory architecture unifies FRAM for code, constants, and data storage with built-in ECC and 10¹⁵ write endurance.
It features four SAC-L3 modules-each configurable as rail-to-rail op-amp (PGA modes ×1–×33), 12-bit DAC, or voltage reference source-and two eCOMP comparators with programmable hysteresis and dual power modes (100 ns / 1 µs response).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2355TRHA | 32KB FRAM, 4KB RAM, 12-channel ADC (vs. 10-channel on MSP430FR2353TRHAR); same SAC-L3 count and pinout. | Required when firmware size exceeds 16KB or additional RAM needed for complex algorithms or larger buffers. | Select MSP430FR2355TRHA if future firmware expansion or multi-sensor fusion logic demands more memory headroom. |
| MSP430FR2153TRHA | No SAC-L3 modules; only two comparators and no programmable-gain op-amps; identical FRAM/RAM and package. | Suitable for simpler analog tasks where discrete op-amps are acceptable and SAC functionality is unused. | Choose MSP430FR2153TRHA only when SAC-L3 is unnecessary and cost reduction is prioritized over analog integration. |
Compared with MSP430FR2353TRHAR, MSP430FR2355TRHA offers double FRAM and RAM for scalable firmware, while MSP430FR2153TRHA removes SAC-L3 entirely-making it a lower-cost option only when advanced analog signal conditioning is not required.

FAQ
What is the maximum operating frequency of the MSP430FR2353TRHAR?
The MSP430FR2353TRHAR 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 supply range (1.8 V to 3.6 V) and temperature range (–40°C to 105°C), enabling real-time processing for sensor fusion and communication protocols without external clock sources.
Does the MSP430FR2353TRHAR include hardware support for cryptographic operations?
No, the MSP430FR2353TRHAR does not include dedicated cryptographic accelerators or hardware security modules. It relies on software-based implementations for encryption or authentication. For secure boot or key storage requirements, external secure elements or higher-tier MSP430FR5xx/6xx devices with AES modules should be evaluated instead of the MSP430FR2353TRHAR.
How many Smart Analog Combo (SAC-L3) modules does the MSP430FR2353TRHAR integrate?
The MSP430FR2353TRHAR integrates four Smart Analog Combo (SAC-L3) modules. Each SAC-L3 can be independently configured as a programmable-gain op-amp (with noninverting/inverting gains from ×1 to ×33), a 12-bit DAC, or a rail-to-rail operational amplifier-providing flexible analog signal conditioning without external components.
What is the standby current consumption of the MSP430FR2353TRHAR in LPM3.5 mode?
In LPM3.5 mode with 32.768-kHz crystal active and SVS enabled, the MSP430FR2353TRHAR consumes 620 nA. This ultra-low current allows multi-year operation on coin-cell or primary batteries in applications such as wireless sensor nodes and portable safety equipment.
Is the MSP430FR2353TRHAR pin-compatible with other devices in the MSP430FR235x family?
Yes, the MSP430FR2353TRHAR is pin-compatible with the MSP430FR2355TRHA in the same 40-pin VQFN (RHA) package. Both share identical pin assignments, electrical characteristics, and peripheral mappings-enabling drop-in replacement where increased FRAM or RAM capacity is needed without PCB redesign.
