Low Power Pulse Counter with SPI Interface

Project Code :TVMAFE720

Objective

Integrate SPI Interface for Communication • Provide a Serial Peripheral Interface (SPI) to allow external microcontrollers or systems to read the count value. The SPI interface should support basic read (and optionally write/reset) operations. • Ensure the SPI logic is low-power and does not dominate the overall power budget.

Abstract

Low-power digital systems are essential in modern embedded and Internet of Things (IoT) applications, where energy efficiency and reliable data communication are critical. Pulse counters are widely used to measure events such as sensor outputs, rotational speed, frequency, and energy consumption. This project presents the design and implementation of a low-power pulse counter integrated with a Serial Peripheral Interface (SPI) for efficient data transfer. The proposed system accurately counts input pulses while minimizing power consumption through optimized sequential logic and clock-gating techniques. The SPI interface enables reliable communication between the pulse counter and an external microcontroller or processor. The design achieves low power operation, scalability, and ease of integration, making it suitable for battery-powered and real-time embedded applications.
