Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE: All voltages referenced to V_SS . The JTAG fuse-blow voltage, V_FB, is allowed to exceed the absolute maximum rating. The voltage is applied
to the TDI/TCLK pin when blowing the JTAG fuse.

The Texas Instruments MSP430C1331 ultralow-power microcontrollers consist of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with five low power modes is optimized to achieve extended battery life in portable measurement applications. The MSP430C1331 features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency.

The digitally controlled oscillator (DCO) of MSP430C1331 allows wake-up from low-power modes to active mode in less than 6 s.

The MSP430C1331 is a microcontroller configuration with two built-in 16-bit timers, one universal serial synchronous/asynchronous communication interfaces (USART), and 48 I/O pins.

Typical applications of MSP430C1331 include sensor systems that capture analog signals, convert them to digital values, and process and transmit the data to a host system. The timers make the configurations ideal for industrial control applications, hand-held meters, etc.
