Working Principle

The MSP430F6749IPEU includes a high-performance 16-bit RISC processor core, an on-chip memory accelerator module, multiple peripherals, and up to 32KB of Flash memory and up to 24KB of RAM. The processor core is based on an ultra-low-power16-bit MSP430 CPU that operates at up to 16MHz and features a wide selection of peripherals, including three enhanced GPIOs, seven timers, three I2C peripherals and a USB 2.0 full-speed controller.

The CPU also includes an on-chip memory accelerator module with 64-bit addressable memory and 32-bit data pathways and a Direct Memory Access controller for up to two independent data channels. The 16-bit architecture reduces the number of cycles needed for a given task, decreasing execution time, power consumption and cost.

The MSP430F6749IPEU also features an extensive analog capabilities, including an analog-to-digital converter (ADC), four 12-bit digital-to-analog converters, two temperature sensors and two comparators. In addition, it supports an advanced ultra-low-power GPIOs with programmable input and output drive strength and slew-ratio. These features enable the design of advanced, energy-efficient, long life embedded applications.

The device features low-power modes that reduce power consumption to as low as 500nA, and provide intelligent power management at the application level. When the device enters low-power modes, it shuts down all unnecessary peripherals and puts the processor core into sleep or idle mode. This intelligent power management helps reduce standby and sleep mode current consumption, enabling longer system operation time before battery recharge.

The MSP430F6749IPEU also includes two time-programmable RAM and registers, allowing critical system parameters to be stored in an on-chip non-volatile memory. The device also supports up to eight channels in the range of 3VI to 3.4VI, which can be used to measure battery status and detect transients in the battery voltage.

The device is well-suited for embedded applications in the consumer, automotive and industrial markets, particularly those that require high performance, low power consumption, and the use of advanced peripheral configurations.
