<title>openMSP430 Overview</title>
</head>
<body>
<h1>Introduction</h1>
The openMSP430 is a synthesizable 16bit microcontroller core written in Verilog. It is compatible with Texas Instruments' MSP430 microcontroller family and can execute the code generated by an MSP430 toolchain in a cycle accurate way.
<br /><br />
The core comes with some peripherals (GPIO, TimerA, generic templates) and a Serial Debug Interface for in-system software development.
