Texas Instruments' eZ430-F2013 USB stick-based development tool enables users of its microcontrollers trim part count in automated metering apps" target=_blank>MSP430 microcontroller architecture to complete an entire MSP430F20xx project from start to finish. The tool is available now for only $20.

The eZ430-F2013 tool connects to a standard PC USB port and is self-powered, requiring no extra cables or power supplies. Contained within the USB stick is an emulation interface board and an easily removable MSP430F2013 target board, which differentiates the eZ430 from other fixed-function evaluation systems.

Using TI's Spy bi-wire debug interface, only two signals, power and ground are needed to connect the emulation interface and target, enabling very compact, high-performance MCU development in a low-cost environment. The emulation board communicates with the MSP430 MCU target devices' emulation logic non-obtrusively, in-system and subject to the same electrical characteristics as the final application, which eliminates costly, time consuming intermediate steps. This board uses a TI TUSB3410 for the USB interface and a TPS77301 to provide 3V regulation to the system. The target board makes all 14 MSP430F2013 pins available on an industry standard 0.1 inch though-hole header and includes an LED for immediate development feedback.

The eZ430 tool includes a free IAR Kick Start Embedded Workbench IDE containing a debugger, assembler and C compiler. This is the same IDE currently used for all MSP430 MCUs, meaning designers can leverage existing code and expertise. To jump-start new projects, users can tap into more than 100 free C and assembler source code examples that are available from TI's website.

The MSP430F2013 MCU is part of the recently introduced MSP430F20xx series, operating up to 16MIPS with no external components. The MSP430F20xx series' fully programmable clock system is stable over temperature and voltage, providing wake-up from 500nA standby to full-speed operation in less than one micro-second. Ultra-low power combined with on-demand high-performance lets designers tune their systems to stay in standby longer so their applications conserve more power and use smaller, lower cost batteries. Operating from 1.8V to 3.6V, the MSP430F20xx MCUs allow direct battery operation and are available in a 14-pin footprint as small as 4-by-4mm.
