Product details
Overview
MSP430FR5723IRHAR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 8 KB FRAM nonvolatile memory, 1 KB RAM, and a 16-channel analog comparator. It operates from 2 V to 3.6 V across –40°C to 85°C and delivers 8-MHz CPU performance with active-mode current as low as 81.4 µA/MHz - optimized for battery-powered sensor management and data acquisition systems.
For engineers reviewing the MSP430FR5723IRHAR datasheet, MSP430FR5723IRHAR pinout, MSP430FR5723IRHAR application, or MSP430FR5723IRHAR equivalent, key selection criteria include FRAM endurance (1015 write cycles), integrated RTC with crystal support, dual eUSCI modules (UART/IrDA/SPI/I²C), and 40-pin VQFN (RHA) package compatibility with industrial-grade thermal pad layout.
Technical Context
The MSP430FR5723IRHAR implements the MSP430xV2 CPU core with hardware multiplier and three-channel DMA, enabling efficient signal processing in LPM3 standby mode (6.3 µA typical). Its FRAM architecture eliminates erase-before-write latency and supports simultaneous read/write operations without wear leveling overhead.
It integrates two enhanced universal serial communication interfaces (eUSCI_A0/A1 for UART/IrDA/SPI; eUSCI_B0 for I²C/SPI), five 16-bit timers (including Timer_A with dual 3-CC instances and Timer_B with triple 3-CC instances), and a 10-bit ADC with internal reference - all synchronized via a flexible clock system with DCO, VLO, LFXT, and HFXT sources.

FAQ
What is the maximum operating frequency of the MSP430FR5723IRHAR?
The MSP430FR5723IRHAR supports a maximum system clock frequency of 8 MHz across its full operating voltage range (2 V to 3.6 V) and temperature range (–40°C to 85°C). This is achieved using the factory-trimmed DCO oscillator or external crystals (LFXT/HFXT), enabling deterministic real-time execution without frequency derating.
Does the MSP430FR5723IRHAR include hardware encryption or secure boot features?
The MSP430FR5723IRHAR does not integrate dedicated hardware encryption engines or secure boot ROM. It relies on software-based cryptographic libraries and the Memory Protection Unit (MPU) to restrict code/data access - sufficient for basic firmware integrity but not certified for FIPS or Common Criteria Level 5 security requirements.
Can the MSP430FR5723IRHAR drive an external crystal for the RTC function?
Yes, the MSP430FR5723IRHAR supports 32-kHz crystals on PJ.4/XIN and PJ.5/XOUT pins to operate the Real-Time Clock in LPM3.5 mode, consuming only 1.5 µA typical. The crystal oscillator circuit includes programmable load capacitance and automatic gain control for reliable startup across temperature and aging.
How many I²C interfaces does the MSP430FR5723IRHAR support?
The MSP430FR5723IRHAR supports one dedicated I²C interface via eUSCI_B0, capable of standard-mode (100 kbps) and fast-mode (400 kbps) operation with multi-slave addressing. It does not include a second I²C port - eUSCI_A0 and eUSCI_A1 are UART/IrDA/SPI-capable only.
Is the MSP430FR5723IRHAR pin-compatible with other devices in the MSP430FR57xx RHA package family?
Yes, the MSP430FR5723IRHAR shares identical pinout, package dimensions, and thermal pad layout with MSP430FR5721IRHAR, MSP430FR5725IRHAR, MSP430FR5727IRHAR, and MSP430FR5729IRHAR in the 40-pin RHA package - enabling hardware reuse across memory and peripheral variants.
