描述The MSP430F2619S ultra-low-power microcontroller features 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 1 µs. The MSP430F2619S is a microcontroller configuration with two built-in 16-bit timers, a fast 12-bit A/D converter, a comparator, dual 12-bit D/A converters, four universal serial communication interface (USCI) modules, DMA, and up to 64 I/O pins. Typical applications include sensor systems that capture analog signals, convert them to digital values, and then process the data for display or for transmission to a host system. Stand-alone RF sensor front end is another area of application.特性Low-Supply Voltage Range 1.8 V to 3.6 V Ultra-Low Power Consumption Active Mode: 365 µA at 1 MHz, 2.2 V Standby Mode (VLO): 0.5 µA Off Mode (RAM Retention): 0.1 µA Wake-Up From Standby Mode in Less than 1 µs 16-Bit RISC Architecture, 62.5-ns Instruction Cycle Time Three-Channel Internal DMA 12-Bit Analog-to-Digital (A/D) Converter With Internal Reference, Sample-and-Hold, and Autoscan Feature Dual 12-Bit Digital-to-Analog (D/A) Converters With Synchronization 16-Bit Timer_A With Three Capture/Compare Registers 16-Bit Timer_B With Seven Capture/Compare-With-Shadow Registers On-Chip Comparator Four Universal Serial Communication Interfaces (USCIs) USCI_A0 and USCI_A1Enhanced UART Supporting Auto-Baud-Rate Detection (LIN) IrDA Encoder and Decoder Synchronous SPI USCI_B0 and USCI_B1 I2C Synchronous SPI Supply Voltage Supervisor/Monitor With Programmable Level Detection Brownout Detector Bootstrap Loader Serial Onboard Programming, No External Programming Voltage Needed Programmable Code Protection by Security Fuse MSP430F2619S 120KB + 256B Flash Memory, 4KB RAM Available in 64-Pin QFP Package or 64-Pin and 80-Pin KGD Options For Complete Module Descriptions, Refer to MSP430x2xx Family User’s Guide (SLAU144).
