Product details
Overview
MSP430FR5734IPWR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller featuring 8 KB of nonvolatile FRAM, 1 KB of RAM, a 10-bit 12-channel ADC, 16-channel analog comparator, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 2 V to 3.6 V across –40°C to 85°C and targets battery-powered sensor nodes in industrial monitoring systems.
For engineers reviewing the MSP430FR5734IPWR datasheet, MSP430FR5734IPWR pinout, MSP430FR5734IPWR application, or MSP430FR5734IPWR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), RTC with calendar mode, LPM3.5 current (1.5 µA), 32-pin TSSOP package compatibility, and integrated hardware multiplier for signal processing.
Technical Context
The MSP430FR5734IPWR implements the MSP430 CPUXV2 core with 16-bit RISC architecture and executes instructions at up to 8 MHz. Its memory subsystem integrates FRAM as unified program/data/storage space with built-in ECC and MPU protection, eliminating flash erase delays and enabling byte-level writes.
Peripherals include two independent eUSCI_A modules (UART/IrDA/SPI) and one eUSCI_B module (I²C/SPI), five 16-bit timers (three Timer_A, three Timer_B), a 32-bit hardware multiplier, and a real-time clock with calendar and alarm functions-all optimized for deterministic low-power operation in intermittent-sensing applications.

FAQ
What is the maximum operating frequency of the MSP430FR5734IPWR?
The MSP430FR5734IPWR operates at up to 8 MHz using its factory-trimmed DCO oscillator or external crystals. This frequency is fully supported across the entire –40°C to +85°C temperature range and 2.0 V to 3.6 V supply voltage, enabling deterministic real-time execution for time-critical sensor sampling and control loops without performance derating.
Does the MSP430FR5734IPWR support hardware UART bootloading?
Yes, the MSP430FR5734IPWR includes a hardware UART bootloader (BSL) accessible via eUSCI_A0 or eUSCI_A1. The BSL requires no external voltage and supports firmware updates over UART using standard TI BSL protocols, enabling field upgrades without JTAG hardware - a key advantage for sealed or remotely deployed devices using the MSP430FR5734IPWR.
How does the FRAM memory in the MSP430FR5734IPWR differ from traditional flash in terms of endurance and write speed?
The MSP430FR5734IPWR's 8 KB FRAM offers 10¹⁵ write cycles - orders of magnitude higher than flash - and performs byte-level writes in 125 ns without erase latency. Unlike flash, FRAM requires no block erase before writing, enabling true EEPROM-like usage for frequent data logging, parameter storage, or firmware patching directly within the MSP430FR5734IPWR application code.
What low-power modes are available on the MSP430FR5734IPWR, and what is the current draw in RTC-active mode?
The MSP430FR5734IPWR supports seven low-power modes, including LPM3.5 where the RTC remains active with a 32-kHz crystal. In this mode, typical current consumption is 1.5 µA - verified across temperature and voltage - allowing decade-scale battery operation in time-stamped sensor applications while maintaining precise calendar functionality within the MSP430FR5734IPWR.
Is the MSP430FR5734IPWR pin-compatible with other devices in the MSP430FR57xx family?
Yes, the MSP430FR5734IPWR in the 32-pin TSSOP (PW) package shares identical pinout and electrical characteristics with MSP430FR5732IPW and MSP430FR5739IPW. This enables direct substitution within the same footprint for design flexibility, firmware reuse, and simplified BOM management across variants - a verified compatibility confirmed by TI's device comparison table and package documentation for the MSP430FR5734IPWR.
