Product details
Overview
MSP430FR2353TPTR 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 SAR ADC, two enhanced comparators, dual eUSCI_A (UART/IrDA/SPI) and dual eUSCI_B (SPI/I²C), and supports sensor signal conditioning in battery-powered industrial safety devices.
For engineers reviewing the MSP430FR2353TPTR datasheet, MSP430FR2353TPTR pinout, MSP430FR2353TPTR application, or MSP430FR2353TPTR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 current (620 nA), SAC programmable gain (×1–×33), 44 I/O count in LQFP-48, and extended temperature operation for smoke detectors and circuit breakers.
Technical Context
The MSP430FR2353TPTR 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 LPMs. Its memory architecture unifies FRAM for code, constants, and data storage with built-in ECC and configurable write protection.
Four SAC-L3 modules operate as rail-to-rail op-amps or 12-bit DACs, each supporting noninverting (×1, ×2, ×3, ×5, ×9, ×17, ×26, ×33) and inverting (×1, ×2, ×4, ×8, ×16, ×25, ×32) PGA modes plus internal 12-bit reference DAC for offset/bias control - all confirmed for MSP430FR235x family including MSP430FR2353TPTR.

FAQ
What is the maximum operating frequency of the MSP430FR2353TPTR?
The MSP430FR2353TPTR features a digitally controlled oscillator (DCO) with frequency-locked loop (FLL) capable of running the CPU at up to 24 MHz. This maximum frequency is achievable across the full operating voltage range (1.8 V to 3.6 V) and temperature range (–40°C to 105°C), with ±1% accuracy at room temperature using the on-chip reference. The MSP430FR2353TPTR maintains timing integrity without external crystals for many applications, though HFXT supports up to 24 MHz for higher precision.
Does the MSP430FR2353TPTR support hardware debugging?
Yes, the MSP430FR2353TPTR supports 2-wire Spy-Bi-Wire (SBW) debugging via dedicated TEST/SBWTCK and RST/NMI/SBWTDIO pins. This interface enables full-speed debugging, flash programming, and real-time register inspection using TI's Code Composer Studio or third-party tools compatible with MSP430 SBW protocol. No external JTAG adapter is required, and SBW operates across all supported voltage and temperature ranges for the MSP430FR2353TPTR.
How many Smart Analog Combo (SAC) modules does the MSP430FR2353TPTR include?
The MSP430FR2353TPTR includes four Smart Analog Combo (SAC-L3) modules, as confirmed in the device family documentation and functional block diagrams. Each SAC can be independently configured as a rail-to-rail operational amplifier or a 12-bit DAC, with programmable gain settings (noninverting ×1–×33, inverting ×1–×32) and internal 12-bit reference DAC for offset/bias control - a feature exclusive to MSP430FR235x devices and present in the MSP430FR2353TPTR.
What is the FRAM endurance specification for the MSP430FR2353TPTR?
The MSP430FR2353TPTR provides 10¹⁵ write cycle endurance for its integrated FRAM memory, verified across the full operating temperature range (–40°C to 105°C). This endurance applies to both program and data FRAM segments (16KB + 512B) and eliminates wear-leveling requirements. Unlike flash, FRAM writes occur at bus speed with no erase delay, enabling reliable high-frequency data logging - a core capability of the MSP430FR2353TPTR in safety-critical monitoring applications.
Which communication interfaces are available on the MSP430FR2353TPTR?
The MSP430FR2353TPTR integrates two enhanced USCI_A modules (supporting UART, IrDA, and SPI) and two enhanced USCI_B modules (supporting SPI and I²C). Notably, eUSCI_B1 supports I²C only per device specification. All interfaces are accessible via multiplexed GPIO pins in the 48-pin LQFP package, with hardware auto-baud detection in UART mode and clock stretching support in I²C - enabling robust wired industrial communications for the MSP430FR2353TPTR.
