Texas Instruments SMD MSP430F149IPMR Microcontroller

About This Item: The Texas Instruments MSP430™ family of ultra-low-power microcontrollers (MCUs) 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 µs. The MSP430F13x, MSP430F14x, and MSP430F14x1 MCUs support two built-in 16-bit timers, a fast 12-bit ADC on the MSP430F13x and the MSP430F14x devices, one USART on the MSP430F13x devices or two USARTs on the MSP430F14x and MSP430F14x1 devices, and 48 I/O pins. The hardware multiplier enhances the performance and offers a broad code and hardware-compatible family solution.Features: Low Supply Voltage Range, 1.8 V to 3.6 V Ultra-Low Power Consumption: Active Mode: 280 µA at 1 MHz, 2.2 V Standby Mode: 1.6 µA Off Mode (RAM Retention): 0.1 µA Five Power-Saving Modes Wakeup From Standby Mode in Less Than 6 µs 16-Bit RISC Architecture, 125-ns Instruction Cycle Time 12-Bit Analog-to-Digital Converter (ADC) With Internal Reference, Sample-and-Hold, and Autoscan Feature 16-Bit Timer_B With Seven Capture/Compare-With-Shadow Registers 16-Bit Timer_A With Three Capture/Compare Registers On-Chip Comparator Serial Onboard Programming, No External Programming Voltage Needed, Programmable Code Protection by Security Fuse Serial Communication Interface (USART), Functions as Asynchronous UART or Synchronous SPI Interface Two USARTs (USART0, USART1) On MSP430F14x and MSP430F14x1 Devices One USART (USART0) On MSP430F13x Devices Family Members (Also See Device Comparison) MSP430F133 8KB + 256 Bytes of Flash Memory,256 Bytes of RAM MSP430F135 16KB + 256 Bytes of Flash Memory,512 Bytes of RAM MSP430F147, MSP430F1471 32KB + 256 Bytes of Flash Memory,1KB of RAM MSP430F148, MSP430F1481 48KB + 256 Bytes of Flash Memory,2KB of RAM MSP430F149, MSP430F1491 60KB + 256 Bytes of Flash Memory,2KB of RAM
