Texas Instruments MSP430F5438 16-Bit Ultra-Low-Power Microcontroller, 256KB Flash, 16KB RAM, 12 Bit ADC, 4 USCIs, 32-bit HW Multi MSP430F5438IZQWR

The MSP430F5438 is a 16-bit ultra-low-power microcontroller designed for applications requiring efficient power management and performance. It operates within a supply voltage range of 2.2 V to 3.6 V and features a low power consumption profile, with typical active mode consumption of 312 ¬µA/MHz at 8 MHz and 3.0 V. The device includes 256 KB of flash memory and 16 KB of RAM, making it suitable for complex applications. This microcontroller is equipped with a 12-bit analog-to-digital converter (ADC) capable of handling up to 14 external and 2 internal channels, along with a hardware multiplier for 32-bit operations. It supports up to four universal serial communication interfaces (USCIs), which can be configured for UART, I¬=C, and SPI communication protocols. The MSP430F5438 also features three 16-bit timers, a real-time clock (RTC), and a 3-channel internal DMA controller, enhancing its capability for time-sensitive tasks. Its architecture allows for fast wake-up from low-power modes, achieving wake-up times of less than 5 ¬µs. This microcontroller is suitable for a variety of applications, including sensor systems, motor control, and portable measurement devices.
