SMBus 2.0 defines a ‘High Power’ class that includes a 4 mA sink current that cannot be driven by I²C chips unless the pull-up resistor is sized to I²C-bus levels. NXP devices have a higher power set of electrical characteristics than SMBus 1.0. The main difference is the current sink capability with V OL = 0.4 V. SMBus low power = 350 μA
Original IBM power supplies for the PC (model 5150), XT and AT included a line-voltage power switch that extended through the side of the computer case. In a common variant found in tower cases, the line-voltage switch was connected to the power supply with a short cable, allowing it to be mounted apart from the power supply.
An ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+4-pin) auxiliary connector providing additional power to the CPU and a main 24-pin power supply connector, an extension of the original 20-pin version. 20-pin Molex 39-29-9202 at the motherboard. 20-pin ...
In a typical example, a socket on a computer motherboard would have one end of a cable plugged into it, while the other end of the cable plugged into a disk drive or other device. Some cables have different types of connectors on them, and some cables can have as many as 16 connectors (allowing 16 devices to be wired together).
In addition to carrying analog RGB video, the connector supports analog stereo audio signals (input and output), Apple Desktop Bus (ADB), and S-video input. [4] Because the AudioVision 14 Display has front-mounted connectors for ADB and audio and video, a single consolidated cable and proprietary connector was used to simplify the connection to the computer and reduce cable clutter.
ITE Super I/O chip (IT8712F) SMSC™ (now Microchip) Super I/O chip (FDC37M813) on IBM motherboard. Super I/O (sometimes Multi-IO) [1] is a class of I/O controller integrated circuits that began to be used on personal computer motherboards in the late 1980s, originally as add-in cards, later embedded on the motherboards.
These cables use a Riser Card PCB and an edge connector on each side of the cable, with a copper alloy surrounded by a plastic insulator that allows for the further data transmission distances. [3] Such cables are now commonly used in modern household gaming PC's to allow for different positioning of PCI Express Cards and GPU cards in a ...
Low Pin Count interface Winbond chip Trusted Platform Module installed on a motherboard, and using the LPC bus. The Low Pin Count (LPC) bus is a computer bus used on IBM-compatible personal computers to connect low-bandwidth devices to the CPU, such as the BIOS ROM (BIOS ROM was moved to the Serial Peripheral Interface (SPI) bus in 2006 [1]), "legacy" I/O devices (integrated into Super I/O ...
