I2C combines features of SPI and UART for multiple master-slave communication. Uses only two wires: SDA for data and SCL for clock. Supports up to 128 unique addresses with 7-bit addresses
Databook contains 235,000 SMD codes for active semiconductor components. Covers diodes, transistors, thyristors and integrated circuits. Includes case pin assignments, pinout, marking style and schematic diagrams. Provides manufacturer information and case drawings
Doping involves intentionally introducing impurities into intrinsic semiconductors. Low doping (1 dopant/100M atoms) is light, high doping (1/10K atoms) is heavy. Doped materials are called extrinsic semiconductors. Highly doped semiconductors behave like conductors
