MSP430F5437IPNR  

16-bit ultra-low-power microcontroller, 256KB of flash memory, 16KB of memory, 12-bit ADC, 2 USCIs, 32-bit hardware multiplier

illustrate   Texas Instruments' MSP430 ultra-low-power microcontroller family includes multiple devices with peripheral sets for a variety of different applications. The architecture, with five low-power modes combined, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and contributes to maximum code efficiency generators. The digitally controlled oscillator (DCO) allows wake-up from low-power mode in active mode for no more than 5 microseconds. The MSP430F543x and MSP430F541x series are three 16-bit timers, a high-performance microcontroller-configured 12-bit analog-to-digital (A/D) converter, four universal serial communication interfaces (USCI), hardware multipliers, DMA, true real-time clock modules with alarm functions, and up to 87 I/O pins.   characteristic   Low supply voltage range: 2.2 V to 3.6 V Ultra-low power consumption Active Mode (AM): All system clock activity 312 microamps/MHz at 8 MHz, 3.0 volts, flash program execution (typical) 140 microamps/MHz at 8 MHz, 3.0 volts, program execution with RAM (typical) Standby Mode (LPM3): Real-Time Clock Crystal, Watchdog, and Power Monitoring Service, RAM Remains Intact, Fast Wake-Up: 3.0 V (typical) at 2.6μA Low Power Oscillator (VLO), Universal Counter, Watchdog, and Supply Supervisor Service, RAM Remains Intact, Fast Wake-Up: 3.0 V (typical) at 1.8μA Off Mode (LPM4): RAM Intact, Supply Supervisor Service, Fast Wake-Up: 3.0 V (typical) at 1.69μA Standby mode with a wake-up time of less than 5μs 16-bit RISC architecture Memory expansion System clock up to 18 MHz Flexible power management system Fully integrated LDO regulation with programmable core supply voltage Power supply voltage monitoring, monitoring, and power failure Unified clock system FLL's stable control loop frequency Low-Power/Low-Frequency Internal Clock Source (VLO) Low-Frequency Edge Internal Reference Source (REFO) Crystal at 32 kHz High frequency up to 32 MHz crystals 16-bit timer TA0 with five Timer_A capture/comparison registers The 16-bit timer TA1 has three Timer_A capture/compare registers
