PCIe Sideband signal operation during lower Power entry and exit In modern applications such as mobile devices, servers, gaming systems, and network storage, there is a growing demand for increased storage capacity. To meet this need, many of these devices are transitioning to solid-state drives (SSDs) using the NVMe protocol over PCIe. While PCIe has […]
During the power-on sequence of a PCI Express (PCIe) system, the reference clock (REFCLK) and sideband signals may not have reached their required stability or operating tolerance. The PERST# (PCIe Reset) signal is an active-low, open-drain output driven by the Root Complex (RC). It is used to hold the endpoint (EP) devices in reset while […]
UFS 4.0 in Automotive: Powering Next-Generation Vehicles In today’s rapidly evolving automotive landscape, vehicles are transforming into sophisticated, connected computing platforms. As manufacturers push the boundaries of safety, connectivity, and user experience, the need for high-performance storage solutions becomes paramount. Universal Flash Storage (UFS) 4.0 is emerging as a critical technology that meets these demands, […]
Understanding Clock Stretching in I²C Communication and How PGY-I2C-EX-PD Simplifies Debugging Efficient communication between devices is crucial in modern embedded systems, especially when using protocols like I²C (Inter-Integrated Circuit). One of the key mechanisms that ensures smooth data transfer between fast masters and slower slaves is clock stretching. This blog explores the importance of clock […]
Universal Flash Storage (UFS) uses the MIPI Alliance’s MPHY physical layer specification to interconnect the UFS device with the host (SoC) or application processor. This is an embedded interface with no connectors between the host and UFS device. In typical electronic systems, the MPHY signals are routed between PCB layers, making them inaccessible. However, test […]
DDR5 is fifth generation dynamic random-access memory provides superior performance over DDR4. It is designed for next generation CPUs and GPU to address artificial intelligence applications and large data processing applications with fast access to the data. One of the key features of the DDR5 is power management integrated circuit (PMIC), which regulates the is […]
Introduction The MIPI I3C Bus interface enhances the legacy I2C standard by reducing the number of physical pins required in sensor systems while supporting low-power, high-speed digital communication, similar to UART and SPI interfaces. This versatility allows for seamless integration with existing systems. I3C is essential for integrating sensors in smartphones, IoT devices, and wearables, […]
Overview In the realm of embedded systems, I2C (Inter-Integrated Circuit) is a widely used communication protocol that enables devices to communicate with each other over a short distance. One critical aspect of I2C communication is clock stretching, which allows slower devices to control the pace of communication by holding the clock line low. One of […]
UFS is becoming widely used storage device in many different applications smartphone, Tablets, Digital Cameras and Camcorders, Automotive, Augmented Reality and Virtual reality, wearable, augmented devices and hard disk drives. Now it expected to used in laptops in the near future. UFS stands for Universal Flash Storage. It is type of non-volatile memory which can […]
MCTP Over I3C in the PGY-I3C-EX-PD Overview of I3C MIPI I3C, or I3C, stands for the MIPI I3C (Sensor Interface) standard, which serves as a versatile and efficient interface for connecting sensors to application processors, microcontrollers, and other intelligent devices. I3C is designed to overcome limitations of traditional sensor interfaces like I2C and SPI by […]
