MSP430P337PJM

The MSP430P337PJM is one member of the MSP430x33x series.The Texas Instruments MSP430 series is a ultra low-power microcontroller family consisting of several devices which features different sets of modules targeted to various applications. The controller is designed to be battery operated for an extended application lifetime. With the 16-bit RISC architecture, 16 integrated registers on the CPU, and the constant generator, the MSP430 achieves maximum code efficiency. The digital-controlled oscillator, together with the frequency lock loop (FLL), provides a fast wake up from a low-power mode to an active mode in less than 6 s. The MSP430x33x series micro-controllers have built in hardware multiplication and communication capability using asynchronous (UART) and synchronous protocols.

Features of the MSP430P337PJM are:(1)low supply voltage range 2.5 V5.5 V; (2)low operation current, 400 A at 1 MHz, 3 V; (3)ultra-low power consumption (standby mode down to 0.1 m A); (4)five power-saving modes; (5)wake up from standby mode in 6 S; (6)16-bit RISC Architecture, 300 ns instruction cycle time; (7)single common 32 kHz crystal, internal system clock up to 3.8 MHz; (8)integrated LCD driver for up to 120 segments; (9)integrated hardware multiplier performs signed, unsigned, and MAC operations for operands Up to 16 X 16 bits; (10)serial communication interface (USART),select asynchronous UART or synchronous spi by software; (11)slope A/D converter using external components; (12)16-bit timer with five capture/compare registers; (13)programmable code protection by security fuse.

The absolute maximum ratings of the MSP430P337PJM can be summarized as:(1)supply voltage range, between Vcc terminals:0.3 V to 0.3 V;(2)supply voltage range, between Vss terminals  :0.3 V to 0.3 V;(3)input voltage range, Vcc1 to any Vss terminal:0.3 V to 6 V;(4)storage temperature:-55 to 150;(5)input voltage range to any terminal (referenced to VSS)  :0.3 V to V  + 0.3 V;(6)diode current at any device terminal:±2 mA.Two counter inputs (load, enable) control the counter operation. The load input controls load operations. A write-access to the counter results in loading the content of the preload register into the counter. The software writes or reads the preload register with all instructions. The preload register acts as a buffer and can be written immediately after the load of the counter is completed. The enable input enables the count operation. When the enable signal is set to high, the counter will count-up each time a positive clock edge is applied to the clock input of the counter.
