The other connectors with the same pin spacing are the DA-26, DB-44, DC-62, DD-78 and 104-pin. They all have three rows of pins, except the DD-78 which has four, and the 104-pin which has five rows. [1] The double density series of D-sub connectors features even denser arrangements and consists of the DE-19, DA-31, DB-52, DC-79, and DD-100 ...
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
100-pin: printer SDRAM and printer ROM (e.g., PostScript) 168-pin: SDR SDRAM sometimes used for FPM/EDO DRAM in workstations or servers, may be 3.3 or 5 V; 184-pin: DDR SDRAM; 200-pin: FPM/EDO DRAM in some Sun workstations and servers; 240-pin: DDR2 SDRAM, DDR3 SDRAM and FB-DIMM DRAM; 278-pin: HP high density SDRAM; 288-pin: DDR4 SDRAM and DDR5 ...
A link is a point-to-point communication channel between two PCI Express ports allowing both of them to send and receive ordinary PCI requests (configuration, I/O or memory read/write) and interrupts (INTx, MSI or MSI-X).
Pin configuration of Type-A and Type-B plugs viewed end-on. (Both shapes are inaccurate.) The Type-A plug. This plug has an elongated rectangular cross-section, inserts into a Type-A receptacle on a downstream port on a USB host or hub, and carries both power and data. Captive cables on USB devices such as keyboards or mice terminate with a ...
GPIO interfaces vary widely. In some cases, they are simple—a group of pins that can switch as a group to either input or output. In others, each pin can be set up to accept or source different logic voltages, with configurable drive strengths and pull ups/downs. Input and output voltages are usually, but not always, limited to the supply ...
In the male connector, this pin numbering corresponds with the cable's wire-and-solder side. The Video Graphics Array ( VGA ) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [ 1 ] as well as many monitors ...
A PIN diode is a diode with a wide, undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts .
