Receiving Notification of Document Updates

To receive notification of documentation updates—including silicon errata—go to the product folder for your device on (for links to product folders, see Section 7.5). In the upper right corner, click the "Alert me" button. This registers you to receive a weekly digest of product information that has changed (if any). For change details, check the revision history of any revised document.


User's Guides

    MSP430 Flash Device Bootloader (BSL) User's Guide

    The MSP430™ bootloader (BSL) lets users communicate with embedded memory in the MSP430 microcontroller (MCU) during the prototyping phase, final production, and in service. Both the programmable memory (flash memory) and the data memory (RAM) can be modified as required.

    MSP430 Programming With the JTAG Interface

    This document describes the functions that are required to erase, program, and verify the memory module of the MSP430 flash-based and FRAM-based microcontroller families using the JTAG communication port. In addition, it describes how to program the JTAG access security fuse that is available on all MSP430 devices. This document describes device access using both the standard 4-wire JTAG interface and the 2-wire JTAG interface, which is also referred to as Spy-Bi-Wire (SBW).

    MSP430 Hardware Tools User's Guide

    This manual describes the hardware of the TI MSP-FET430 Flash Emulation Tool (FET). The FET is the program development tool for the MSP430 ultra-low-power microcontroller. Both available interface types, the parallel port interface and the USB interface, are described.

Application Reports

    MSP430 32-kHz Crystal Oscillators

    Selection of the right crystal, correct load circuit, and proper board layout are important for a stable crystal oscillator. This application report summarizes crystal oscillator function and explains the parameters to select the correct crystal for MSP430 ultra-low-power operation. In addition, hints and examples for correct board layout are given. The document also contains detailed information on the possible oscillator tests to ensure stable oscillator operation in mass production.

    General Oversampling of MSP ADCs for Higher Resolution

    Multiple MSP430 ultra-low-power microcontrollers offer ADCs to convert physical quantities into digital numbers, a function that is widely used across numerous applications. There are times, however, when a customer design demands a higher resolution than the ADC of the selected MSP can offer. This application report describes how an oversampling method can be incorporated to increase ADC resolution past the currently available number of bits.

    MSP430 System-Level ESD Considerations

    System-Level ESD has become increasingly demanding with silicon technology scaling towards lower voltages and the need for designing cost-effective and ultra-low-power components. This application report addresses three different ESD topics to help board designers and OEMs understand and design robust system-level designs.
