The Texas Instruments MSP430 family of ultralow-power microcontrollers consists 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 contribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 5 μs. The MSP430F543x(A) and MSP430F541x(A) series are microcontroller configurations with three 16-bit timers, a high performance 12-bit analog-to-digital (A/D) converter, up to four universal serial communication interfaces (USCI), hardware multiplier, DMA, real time clock module with alarm capabilities, and up to 87 I/O pins.
Typical applications for this device include analog and digital sensor systems, digital motor control, remote controls, thermostats, digital timers, hand-held meters, etc.
The MSP430X CPU incorporates features specifically designed for modern programming techniques such as calculated branching, table processing and the use of high-level languages such as C. The MSP430X CPU can address a 1-MB address range without paging. The MSP430X CPU is completely backwards compatible with the MSP430 CPU.
The MSP430X CPU features include:
• RISC architecture
• Orthogonal architecture
• Full register access including program counter, status register and stack pointer
• Single-cycle register operations
• Large register file reduces fetches to memory.
• 20-bit address bus allows direct access and branching throughout the entire memory range without paging.
• 16-bit data bus allows direct manipulation of word-wide arguments.
• Constant generator provides the six most often used immediate values and reduces code size.
• Direct memory-to-memory transfers without intermediate register holding.
• Byte, word, and 20-bit address-word addressing

MSP430F543x 100引腳目標(biāo)板MSP-TS430PZ5X100
MSP430F5xx 100-Pin Socket Target Board MSP-TS430PZ5X100,
The MSP-FET430U5x100 is a powerful flash emulation tool (FET) that includes the hardware and software required to quickly begin application development on the MSP430 MCU. It includes a ZIF socket target board (MSP-TS430PZ5x100) and a USB debugging interface (MSP-FET430UIF) used to program and debug the MSP430 in-system through the JTAG interface or the Spy Bi-Wire (2-wire JTAG) protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is ultra-low power, no external power supply is required.
The debugging tool interfaces the MSP430 to the included integrated software environment and includes code to start your design immediately. The included MSP-TS430PZ5x100 development board supports all MSP430F5xx flash parts in a 100-pin TQFP package (TI package code: PZ).
The 100-pin socket target board (MSP-TS430PZ5x100) is also available standalone without the additional debugging interface.
