Overview
MSP430FR5728IRGET from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16KB ferroelectric RAM (FRAM), 1KB SRAM, 8-MHz system clock, 10-bit ADC with 6 external channels, and 10-channel analog comparator. It operates across 2 V–3.6 V supply and –40°C to 85°C, targeting battery-powered sensor nodes and energy-harvesting data loggers.
For engineers reviewing the MSP430FR5728IRGET datasheet, MSP430FR5728IRGET pinout, MSP430FR5728IRGET application, or MSP430FR5728IRGET equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), RTC-enabled LPM3.5 current (1.5 µA), eUSCI_A0/A1 UART/IrDA/SPI support, and 24-pin VQFN package compatibility with space-constrained PCB layouts.

FAQ
What is the maximum operating frequency of the MSP430FR5728IRGET?
The MSP430FR5728IRGET supports a maximum system clock frequency of 8 MHz, achieved via its factory-trimmed DCO oscillator or external HFXT crystal. This speed enables real-time processing of sensor data while maintaining ultra-low active-mode current (81.4 µA/MHz typical), making it ideal for responsive yet energy-efficient edge nodes. The MSP430FR5728IRGET sustains this performance across its full 2 V–3.6 V supply range.
Does the MSP430FR5728IRGET include hardware encryption or secure boot features?
No, the MSP430FR5728IRGET does not integrate hardware cryptographic accelerators or secure boot functionality. Its security model relies on software-based approaches and the Memory Protection Unit (MPU) to restrict code/data access. For applications requiring certified secure execution, designers should consider TI's MSP430FR59xx series or companion secure elements. The MSP430FR5728IRGET prioritizes ultra-low power and FRAM endurance over cryptographic capability.
Can the MSP430FR5728IRGET drive an external crystal for the RTC function?
Yes, the MSP430FR5728IRGET supports a 32-kHz crystal connected to PJ.4/XIN and PJ.5/XOUT pins to operate the Real-Time Clock in LPM3.5 mode, achieving 1.5 µA typical current consumption. This configuration provides high-accuracy timekeeping essential for scheduled wake-ups in data loggers. The MSP430FR5728IRGET's LFXT oscillator circuit includes automatic gain control and fault detection to ensure reliable crystal startup and operation.
How many general-purpose I/O pins does the MSP430FR5728IRGET provide in the RGE package?
The MSP430FR5728IRGET in the 24-pin VQFN (RGE) package provides 17 general-purpose I/O pins, including P1.0–P1.5, P1.7, P2.0–P2.6, PJ.0–PJ.3, and RST/NMI/SBWTDIO (configured as GPIO after reset release). All support interrupt and wake-up from low-power modes. Pin functions are multiplexed with peripherals like timers, ADC, and eUSCI modules, enabling flexible resource allocation in compact designs.
Is the MSP430FR5728IRGET compatible with Code Composer Studio IDE?
Yes, the MSP430FR5728IRGET is fully supported by Texas Instruments' Code Composer Studio™ IDE (CCS), including compiler toolchain, debugger integration, and out-of-box examples for FRAM usage, low-power modes, and peripheral initialization. CCS v10+ provides optimized MSP430FR57xx device support, enabling rapid development of energy-efficient firmware.
