Product details
Overview
MSP430FR2353TPT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 48-pin LQFP package, featuring 16KB program FRAM, 2KB RAM, 12-bit SAR ADC (200 ksps), four Smart Analog Combo (SAC-L3) modules, and dual eUSCI_A/eUSCI_B peripherals. It operates from 1.8 V to 3.6 V across –40°C to 105°C and targets battery-powered sensor signal conditioning and industrial monitoring systems.
For engineers reviewing the MSP430FR2353TPT datasheet, MSP430FR2353TPT pinout, MSP430FR2353TPT application, or MSP430FR2353TPT equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), integrated SAC-based programmable-gain op-amps, low-power LPM3.5 mode (620 nA), and 44 GPIOs with interrupt wake-up capability.
Technical Context
The MSP430FR2353TPT implements a 16-bit RISC CPU with 24-MHz DCO+FLL clock system, supporting sub-10 µs wake-up from LPM3.5. Its analog subsystem integrates four SAC-L3 modules-each configurable as rail-to-rail OA, PGA (gain ×1–×33), or 12-bit DAC-and two enhanced comparators with 6-bit internal DAC reference.
Digital peripherals include Timer_B3 (3 capture/compare registers), Timer_B7 (7 capture/compare registers), RTC counter, 16-bit CRC, MPY32 hardware multiplier, and Manchester codec. Memory architecture unifies FRAM for code/data/storage with ECC protection and configurable write protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2355TPT | 32KB FRAM, 4KB RAM, identical SAC/ADC/peripheral set; same 48-pin LQFP package and pinout. | Higher memory headroom for complex firmware, larger FFT buffers, or extended data logging duration. | Select when firmware size exceeds 16KB or long-term FRAM data retention under heavy write loads is required. |
| MSP430FR2153TPT | No SAC modules; retains 12-bit ADC, eCOMP, timers, and FRAM-but lacks programmable-gain op-amps and DAC-based signal conditioning. | Cost-sensitive applications where external analog front-end is acceptable and SAC functionality is unnecessary. | Choose only if SAC features are unused; otherwise, MSP430FR2353TPT provides superior analog integration and BOM reduction. |
Compared with MSP430FR2355TPT, the MSP430FR2353TPT trades half the FRAM/RAM for lower cost while retaining full SAC/ADC/peripheral functionality; versus MSP430FR2153TPT, it adds four SAC-L3 modules enabling self-contained analog signal chains without external components.

FAQ
What is the maximum operating frequency of the MSP430FR2353TPT?
The MSP430FR2353TPT supports a maximum CPU clock frequency of 24 MHz, achieved via its on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL). This allows deterministic real-time execution while maintaining ultra-low power consumption in active mode (142 µA/MHz at 3 V).
Does the MSP430FR2353TPT include hardware encryption or secure boot features?
No, the MSP430FR2353TPT does not integrate hardware encryption accelerators or secure boot functionality. It relies on software-based security measures and external secure elements for cryptographic operations; its primary focus is ultra-low-power analog/mixed-signal performance rather than security-centric features.
How many Smart Analog Combo (SAC) modules does the MSP430FR2353TPT have, and what functions do they support?
The MSP430FR2353TPT includes four Smart Analog Combo (SAC-L3) modules. Each supports configurable operational amplifier (OA), programmable-gain amplifier (PGA) with gains from ×1 to ×33, and 12-bit DAC for offset/bias control-enabling fully integrated analog front-end design without external components.
What is the FRAM endurance specification for the MSP430FR2353TPT?
The MSP430FR2353TPT features ferroelectric RAM with 10¹⁵ write cycle endurance-orders of magnitude higher than flash or EEPROM. This enables continuous data logging in applications like smoke detectors and sensor transmitters without wear-out concerns over product lifetime.
Is the MSP430FR2353TPT pin-compatible with other members of the MSP430FR235x family?
Yes, the MSP430FR2353TPT in 48-pin LQFP (PT) package shares identical pinout and electrical characteristics with MSP430FR2355TPT, allowing direct substitution where firmware fits within 16KB FRAM. Pin compatibility does not extend to MSP430FR215x variants due to absence of SAC modules.
