Product details
Overview
MSP430FR2355TPTR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 32KB program FRAM, 4KB RAM, and four Smart Analog Combo (SAC-L3) modules supporting configurable op-amps and 12-bit DACs. It operates from 1.8 V to 3.6 V across –40°C to 105°C, features 44 GPIOs in LQFP-48, and targets sensor signal conditioning and battery-powered industrial sensing.
For engineers reviewing the MSP430FR2355TPTR datasheet, MSP430FR2355TPTR pinout, MSP430FR2355TPTR application, or MSP430FR2355TPTR equivalent, key selection criteria include FRAM endurance (1015 writes), LPM3.5 current (620 nA), SAC-L3 programmable gain (×1–×33), 12-bit SAR ADC (200 ksps), and dual eUSCI_A/B for UART/I²C/SPI in compact industrial designs.
Technical Context
The MSP430FR2355TPTR integrates a 24-MHz DCO-based clock system with FLL, ±1% accuracy at room temperature, and support for external HFXT (up to 24 MHz) and LFXT (32.768 kHz). Its memory subsystem combines 32KB FRAM + 512B data FRAM + 4KB SRAM, with ECC and configurable write protection.
Four SAC-L3 modules each provide rail-to-rail OA/PGA/DAC functionality with independent power modes; two enhanced comparators include 6-bit reference DACs and selectable hysteresis; and Timer_B7 (7 CCR) plus three Timer_B3 modules enable precise timing and PWM generation for sensor interface and control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2355TPT | Same die, identical FRAM/RAM/peripherals, but in leaded LQFP-48 (no tape-and-reel packaging) | No functional difference; TPT is tray-packaged, TPTR is tape-and-reel - same electrical and thermal behavior | Select TPTR for automated SMT assembly; choose TPT for prototyping or low-volume hand-soldering |
| MSP430FR2155TPTR | Same package and pinout, but lacks SAC-L3 modules; retains 12-bit ADC, comparators, and FRAM | Cannot replace SAC-dependent analog front ends; suitable only where discrete op-amps or simpler signal chains are used | Choose MSP430FR2155TPTR only when SAC functionality is unnecessary and cost reduction is prioritized |

FAQ
What is the maximum operating frequency of the MSP430FR2355TPTR?
The MSP430FR2355TPTR features a digitally controlled oscillator (DCO) with frequency-locked loop (FLL) capable of operating up to 24 MHz. 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), as confirmed in the device's electrical characteristics and clock system documentation. The MSP430FR2355TPTR maintains timing compliance at this speed under specified conditions.
Does the MSP430FR2355TPTR support hardware real-time debugging?
Yes, the MSP430FR2355TPTR supports hardware real-time debugging via its integrated Spy-Bi-Wire (SBW) interface using the TEST/SBWTCK and RST/NMI/SBWTDIO pins. This 2-pin interface enables full-speed debugging, flash programming, and breakpoint execution without halting peripheral operation - essential for validating timing-critical sensor algorithms during development of MSP430FR2355TPTR-based systems.
How many analog input channels does the MSP430FR2355TPTR ADC support?
The MSP430FR2355TPTR integrates a 12-bit SAR analog-to-digital converter with up to 12 single-ended input channels. These channels map to dedicated analog pins (A0–A11) and are accessible through the device's port multiplexing scheme. Channel count is fixed and verified in the device comparison table and ADC section of the MSP430FR2355TPTR datasheet.
What is the purpose of the Smart Analog Combo (SAC-L3) modules in the MSP430FR2355TPTR?
The MSP430FR2355TPTR includes four SAC-L3 modules, each combining a rail-to-rail operational amplifier, programmable-gain amplifier (gain ×1–×33), and 12-bit DAC. These modules enable configurable analog signal conditioning - such as sensor amplification, offset adjustment, and reference generation - without external components, reducing BOM cost and PCB footprint in MSP430FR2355TPTR-based sensor nodes.
Is the MSP430FR2355TPTR pin-compatible with other devices in the MSP430FR235x family?
Yes, the MSP430FR2355TPTR is pin-compatible with other 48-pin LQFP variants in the MSP430FR235x family, including MSP430FR2353TPTR. Both share identical pinouts, peripheral mappings, and package dimensions (7 mm × 7 mm). Functional differences (e.g., 32KB vs. 16KB FRAM, 4KB vs. 2KB RAM) do not affect physical compatibility, allowing drop-in replacement where memory requirements align.
