Product details
Overview
MSP-FET430U28A from Texas Instruments is a USB-based Flash Emulation Tool (FET) debugger interface for MSP430 microcontrollers, supporting JTAG and Spy-Bi-Wire (SBW) protocols, delivering 5 V target power, operating up to 25 MHz SWD clock, and enabling full-speed debugging, flash programming, and real-time trace on MSP430F1xx through MSP430FR6xx device families.
For engineers reviewing the MSP-FET430U28A datasheet, MSP-FET430U28A pinout, MSP-FET430U28A application, or MSP-FET430U28A equivalent, this tool is essential for low-power embedded development, firmware validation, energy profiling with EnergyTrace™, and production-ready debug infrastructure across TI's ultra-low-power MCU portfolio.
Technical Context
The MSP-FET430U28A implements a dedicated USB 2.0 Full-Speed interface to host PCs and integrates TI's proprietary emulation logic compatible with Code Composer Studio v10.x and legacy versions. It supports both JTAG (4-wire) and Spy-Bi-Wire (2-wire) physical interfaces, with automatic protocol detection and dynamic voltage translation from 1.8 V to 5 V for target compatibility.
It provides regulated 5 V @ 500 mA output to power target boards, includes integrated level-shifting circuitry for mixed-voltage debugging, and enables hardware breakpoints, watchpoints, and memory access via the Enhanced Emulation Module (EEM) of supported MSP430 devices - all without requiring external power or level translators.

FAQ
What is the MSP-FET430U28A used for?
The MSP-FET430U28A is a production-grade USB debug probe used to program, debug, and profile MSP430 microcontrollers via JTAG or Spy-Bi-Wire. It enables full IDE integration with Code Composer Studio, supports EnergyTrace™ technology for current/power measurement, and delivers regulated 5 V power to target boards - making it indispensable for firmware development, low-power validation, and production programming workflows involving the MSP-FET430U28A.
Does the MSP-FET430U28A support MSP430FR5969?
Yes, the MSP-FET430U28A fully supports the MSP430FR5969 FRAM-based MCU, including flash programming, real-time debugging, hardware breakpoints, and EnergyTrace++ mode. TI documentation explicitly lists MSP430FR5xx/FR6xx families as supported, and the MSP-FET430U28A firmware (v3.0+) includes password protection handling and BSL access features required by the MSP430FR5969 - confirming native compatibility with the MSP-FET430U28A.
How does the MSP-FET430U28A differ from the MSP-FET430UIF?
The MSP-FET430U28A replaces the legacy MSP-FET430UIF with enhanced USB reliability, broader voltage range (1.8–5.0 V vs. 2.2–3.6 V), higher SWD clock (25 MHz vs. 12 MHz), and native support for MSP430FRxx FRAM devices. Unlike the MSP-FET430UIF, the MSP-FET430U28A includes improved ESD protection, integrated 5 V power regulation, and full backward compatibility - making the MSP-FET430U28A the recommended debug interface for new MSP430 designs.
Can the MSP-FET430U28A be used with IAR Embedded Workbench?
No - the MSP-FET430U28A is designed exclusively for use with Texas Instruments' Code Composer Studio IDE and TI's MSP Debug Stack. It is not supported by IAR Embedded Workbench, which requires I-jet or I-scope debug probes. While third-party tools may offer limited JTAG/SBW access, official functionality, EnergyTrace™ integration, and BSL password handling are only guaranteed within the TI toolchain - so the MSP-FET430U28A must be used with CCS to realize its full capability.
Is the MSP-FET430U28A compatible with Windows 11 and CCS v11?
Yes, the MSP-FET430U28A is fully compatible with Windows 11 and Code Composer Studio v11.x. TI's MSP Debuggers User's Guide confirms USB HID-class driver support without additional INF installation, and CCS v11 retains full backward compatibility with all MSP-FET430U28A firmware versions (v2.0+). The MSP-FET430U28A continues to support all documented MSP430 families, EnergyTrace™, and secure BSL access - ensuring seamless operation across the latest TI development environment - including the MSP-FET430U28A.
