MSP430F149IRTDR

The MSP430F149IRTDR from Texas Instruments is a highly integrated, ultra-low-power microcontroller based on the 16-bit MSP430 CPU16 core. It offers 60KB of Flash program memory and 2KB of SRAM, making it suitable for a wide range of embedded applications.

This device operates at frequencies up to 8MHz and supports a supply voltage range of 1.8V to 3.6V. Key peripherals include an 8-channel, 12-bit Analog-to-Digital Converter (ADC) with internal reference and sample-and-hold capabilities, two USART modules that can function as asynchronous UART or synchronous SPI interfaces, and on-chip comparators. It also features multiple timers, including Timer_A and Timer_B.

The MSP430F149IRTDR is available in a 64-VQFN exposed pad package, designed for surface mounting. It operates within a temperature range of -40°C to 85°C. The microcontroller supports various power-saving modes, with active mode consumption as low as 280 µA at 1 MHz and 2.2 V, and standby mode consuming only 1.6 µA.

This MCU is well-suited for applications requiring low power consumption and efficient processing, such as portable measurement equipment, industrial control systems, and consumer electronics.
