Introduction and solutions for various industries with digital content and signal analysis in consumer electronics. Such as MIPI I3C etc.

eSPI (Enhanced Serial Peripheral Interface) - eSPI Analysator

Enhanced Serial Peripheral Interface (eSPI) is the transmission protocol used in the new generation of base boards. Its specification is the integration of SMBus/LPC/SPI Flash Interface to simplify the bus and increase the transmission efficiency.

MIPI I3C - Interface and Analysis

MIPI I3C is a serial communications interface specification that improves the features, performance and power consumption of I²C while maintaining backward compatibility for most devices.

MIPI I3C offers the advantages of I²C in terms of simplicity, low pin count, simple PCB design and multi-drop (as opposed to point-to-point), but offers the higher data rates, simpler pads and lower power consumption of SPI. MIPI I3C then adds higher throughput for a given frequency, in-band interrupts (from target to controller), dynamic addressing, advanced power management and hot join.

MIPI I3C was originally intended for mobile applications as a single interface that can be used for all digitally connected sensors, but it has now evolved to be used for all medium-speed embedded applications and for deeply embedded applications involving sensors, actuators, power controllers, MCUs, FPGAs, etc. The interface is also useful for other applications as it provides high-speed data transfer at very low power consumption while allowing multidrop, which is highly desirable for any embedded system.

DDR5 also uses MIPI I3C as one of the core technologies for DDR5 SPD. By using MIPI I3C instead of I2C, the bit rate can be increased by 12.5 to 125 times, depending on the actual design conditions.

MIPI I3C Protocol Analyzer can be very helpful to perform MIPI I3C packet sniffing. Acute Analyzer also provides MIPI I3C trigger and decode software to debug your MIPI I3C packets by cascading with other brands' oscilloscopes, such as Keysight, R&S, Tektronix, Acute TS series, etc.
