Datasheet
A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to understand the role of the component in the overall system. Typically, a datasheet is created by the manufacturer and begins with an introductory page describing the rest of the document, followed by listings of specific characteristics, with further information on the wikt:connectivity, connectivity of the devices. In cases where there is relevant source code to include, it is usually attached near the end of the document or separated into another file. Datasheets are created, stored, and distributed via product information management or product data management systems. Depending on the specific purpose, a datasheet may offer an average value, a typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FD1771 FDC Datasheet
The FD1771, sometimes WD1771, is a floppy disk controller chip, the first in a line of floppy disk controllers produced by Western Digital. It uses single density FM encoding introduced in the IBM 3740. Later models in the series added support for MFM encoding and increasingly added onboard circuitry that formerly had to be implemented in external components. Originally packaged as 40-pin dual in-line package (DIP) format,"The FD1771 is a single-chip floppy disk formatter/controller that interfaces with most available disk drives and virtually all types of computers." The FD1771 was announced on July 19, 1976, and sold for $60 each in lots of 100. later models moved to a 28-pin format that further lowered implementation costs. Derivatives The FD1771 was succeeded by many derivatives that were mostly software-compatible: *The FD1781 was designed for double density, but required external modulation and demodulation circuitry, so it could support MFM, M2FM, GCR or other doub ...

Electronic Component
An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components and elements. A datasheet for an electronic component is a technical document that provides detailed information about the component's specifications, characteristics, and performance. Discrete circuits are made of individual electronic components that only perform one function each as packaged, which are known as discrete components, although strictly the term discrete component refers to such a component with semiconductor material such as individual transistors. Electronic components have a number of electrical terminals or leads. These leads connect to other electrical components, often over wire, ...

Specification (technical Standard)
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard. There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts. They often refer to particular documents, and/or particular information within them. The word ''specification'' is broadly defined as "to state explicitly or in detail" or "to be specific". A requirement specification is a documented requirement, or set of documented requirements, to be satisfied by a given material, design, product, service, etc. It is a common early part of engineering design and product development processes in many fields. A functional specification is a kind of requirement specification, and may show functional block diagrams. A design or product specification describes the features of the ''solutions'' for the Requirement Specificatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Guide
A user guide, also commonly known as a user manual, is intended to assist users in using a particular product, service or application. It is usually written by a technician, product developer, or a company's customer service staff. Most user guides contain both a written guide and associated images. In the case of computer applications, it is usual to include screenshots of the human-machine interface(s), and hardware manuals often include clear, simplified diagrams. The language used is matched to the intended audience, with jargon kept to a minimum or explained thoroughly. Contents of a user manual The sections of a user manual often include: *A cover page *A title page and copyright page *A preface, containing details of related documents and information on how to navigate the user guide *A contents page *A Purpose section. This should be an overview rather than detail the objective of the document *An Audience section to explicitly state who is the intended audience who is ...

Trade Literature
Trade literature is a general term including advertising, customer technical communications, and catalogues. Trade journal A trade magazine, or trade rag, also called a professional magazine, is a magazine published with the intention of target marketing to a specific industry or type of trade. The collective term for this area of publishing is the trade press. Trade magazines typically contain advertising content centered on the industry in question with little if any general-audience advertising. Trade catalog Definitions of the term "trade catalog" vary, but originally, trade catalogs are printed materials published by manufacturing, wholesaling, or retailing firms. They promote sales by making advertising claims, give instructions in using products, provide testimonials from satisfied customers, and include detailed descriptions of sale products. Trade catalogs first appeared in the 18th century, with the expansion in trade, commerce Commerce is the organized Complex s ...

Brochure
A brochure is an promotional document primarily used to introduce a company, organization, products, or services and inform prospective customers or members of the public of the benefits. Although, initially, a paper document that can be folded into a template, pamphlet, or Folded leaflet, leaflet, a brochure can also be a set of related unfolded papers put into a pocket folder or packet or can be in digital format. A brochure is a corporate marketing instrument to promote a product or service. It is a tool used to circulate information about the product or service. A brochure is like a magazine but with pictures of the product or the service which the brand is promoting. Depending on various aspects there are different types of brochures: Gate Fold Brochures, Trifold Brochures, and Z-Fold Brochures. Brochures are distributed in many ways: as newspaper inserts, handed out personally, by mail, or placed in brochure racks in high-traffic locations, especially in tourist precincts. ...
