The de facto standard for 3.5 inch drives uses a 34-pin header mating to an IDC Berg connector, collectively slightly smaller than the PCB edge pin connector and mating socket used for the 5¼ inch standard but with the same 34 pin definitions as the 5¼ inch standard. [7] A separate connector is provided for DC power. [1]
A plug-in bus duct system or busway can have disconnect switches and other devices mounted on it, for example, to distribute power along a long building. Many forms of busway allow plug-in devices such as switches and motor starters to be easily moved; this provides flexibility for changes on an assembly line, for example. [4]
The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi in the 1980s. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 40 character lines. Using an extension driver, the device can display up to 80 characters. [1]
Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
Hitachi HD64180 DIP64. The HD64180 is a Z80-based embedded microprocessor developed by Hitachi with an integrated memory management unit (MMU) and on-chip peripherals. [1] It appeared in 1985. [2] The Hitachi HD64180 "Super Z80" was later licensed to Zilog and sold by them as the Z64180 and with some enhancements as the Zilog Z180.
An 82GB Hitachi Deskstar hard disk. Deskstar was the name of a product line of computer hard disk drives.It was originally announced by IBM in October 1994. [1] The line was continued by Hitachi, when in 2003 it bought IBM's hard disk drive division and renamed it Hitachi Global Storage Technologies.
Advanced security capabilities include Hitachi Data Retention Utility software with its “write once, read many” feature that protects data from overwrites or erasures for long periods of time. System management access limits authorization to change the system. System audit logging records all system changes.
In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant.
