MSP430F135IPM

The MSP430F135IPM is one member of the MSP430 series.The Texas Instruments MSP430 family of 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 device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency.The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6 s.

Features of the MSP430F135IPM are:(1)five power-saving modes; (2)wake-up from standby mode in less than 6 s; (3)16-bit RISC architecture,125-ns instruction cycle time; (4)12-bit A/D converter with internal reference, sample-and-hold and autoscan feature; (5)16-bit timer_b with seven capture/compare-with-shadow registers; (6)16-bit timer_a with three capture/compare registers; (7)on-chip comparator; (8)serial onboard programming,no external programming voltage needed programmable code protection by security fuse; (9)low supply-voltage range, 1.8 V . . . 3.6 V.

The absolute maximum ratings of the MSP430F135IPM can be summarized as:(1)voltage applied at Vcc to Vss:-0.3 to 4.1V;(2)storage temperature range:-40 to 85;(3)voltage applied to any pin (see Note):-0.3 V to VCC+0.3 V;(4)diode current at any device terminal:±2mA.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.Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if the TMS is being held low during power up. The second positive edge on the TMS pin deactivates the fuse check mode. After deactivation, the fuse check mode remains inactive until another POR occurs. After each POR the fuse check mode has the potential to be activated.
