Battery-powered water meters face a challenge: continuously measuring water flow information while consuming as little power as possible. The EVM430-FR6989 used in this design uses a MSP430 FRAM-based microcontroller, which can provide 100uA/MHz active mode current and 450nA standby mode current, support real-time clock function, and integrate low-power analog and digital peripherals. Additionally, the MCU offers virtually unlimited write endurance, fast/low power writes and data flexibility. This reference design demonstrates how to use the integrated Extended Scan Interface (ESI) on a microcontroller to achieve ultra-low power consumption (versus the same detection method using external circuitry). In a water meter design, if coupled to the LC rotation detection sensor (supplied), the ESI continuously detects thruster rotation while the rest of the microcontroller is in a low power mode. The design automates the measurement process and reduces CPU involvement by using the ESI integrated in the MSP430 MCU, which helps reduce overall power consumption.
The 4K Ultra HD display reference design enables emerging applications of DLP Cinema® technology such as digital signage, laser TVs, and office or education projectors that require cost-effective high-resolution solutions for large, bright digital displays. Comes proven and reliable performance. Delivering twice as many pixels as competing products, DLP micromirror technology's advanced image processing and high-speed switching capabilities enable 8.3 million pixels of resolution on the screen, delivering clear and detailed images for any scene. Whether a stand-alone display system or embedded into an existing design, complete reference designs and development guides accelerate display product innovation.
