SLAS706E –JULY 2011–REVISED AUGUST 2013
SYS/BIOS
SYS/BIOS is an advanced real-time operating system for the MSP430 microcontrollers. It features preemptive
deterministic multi-tasking, hardware abstraction, memory management, and real-time analysis. SYS/BIOS is
available free of charge and is provided with full source code.
Command-Line Programmer
MSP430 Flasher is an open-source, shell-based interface for programming MSP430 microcontrollers through a
FET programmer or eZ430 using JTAG or Spy-Bi-Wire (SBW) communication. MSP430 Flasher can be used to
download binary files (.txt or .hex) files directly to the MSP430 microcontroller without the need for an IDE.

processors from Texas Instruments and to foster innovation and growth of general knowledge about the
hardware and software surrounding these devices.
Device and Development Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
MSP430™ MCU devices and support tools. Each MSP430™ MCU commercial family member has one of two
prefixes: MSP or XMS (for example, MSP430F5259). Texas Instruments recommends two of three possible
prefix designators for its support tools: MSP and MSPX. These prefixes represent evolutionary stages of product
development from engineering prototypes (with XMS for devices and MSPX for tools) through fully qualified
production devices and tools (with MSP for devices and MSP for tools).
Device development evolutionary flow:
XMS – Experimental device that is not necessarily representative of the final device's electrical specifications
MSP – Fully qualified production device
Support tool development evolutionary flow:
MSPX – Development-support product that has not yet completed Texas Instruments internal qualification
testing.
MSP – Fully-qualified development-support product
XMS devices and MSPX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
MSP devices and MSP development-support tools have been characterized fully, and the quality and reliability of
the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (XMS) have a greater failure rate than the standard production devices.
Texas Instruments recommends that these devices not be used in any production system because their
expected end-use failure rate still is undefined. Only qualified production devices are to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type
(for example, PZP) and temperature range (for example, T). Figure 1 provides a legend for reading the complete
device name for any family member.
