Have you migrated a design from I2C to SPMI? Or struggled with CRC errors on the power bus? Share your experience in the comments below.
Developed by Philips (now NXP Semiconductors) in 1982, I2C was designed to solve a simple problem: reduce the number of wires and pins needed to connect low-speed peripherals to a processor. Instead of parallel address and data buses, I2C uses just two bidirectional lines. spmi vs i2c
The protocol is the industry veteran. Developed in 1982, it is famous for its "two-wire" simplicity: SDA (Serial Data): A bidirectional line for data. SCL (Serial Clock): The line that keeps everyone in sync. Have you migrated a design from I2C to SPMI
