Question 1

What is the Mfr

Accepted Answer

Mfr refers to the component's producing company, whose brand and manufacturing processes directly impact the component's performance, consistency, and traceability, making it a key reference during selection.

Question 2

What is the Series

Accepted Answer

Series indicates a manufacturer’s organized range of components, often named with a common prefix or code, to streamline product selection and ensure compatibility across similar models.

Question 3

What is the Package

Accepted Answer

his term denotes the protective casing (often made of plastic, ceramic, or metal) that encapsulates an integrated circuit, determining its size, reliability, and suitability for different mounting technologies like through-hole or SMT.

Question 4

What is the Base Product Number

Accepted Answer

By using the Base Product Number, manufacturers and customers can efficiently communicate about component families without detailing every specification, streamlining the procurement process.

Question 5

What is the Supplier Device Package

Accepted Answer

Supplier Device Package refers to the specific nomenclature or code used by a component manufacturer or distributor (supplier) to designate the physical outline and pin arrangement of an electronic component they produce or sell.

Question 6

What is the Memory Size

Accepted Answer

The total data storage capacity of a semiconductor memory device, measured in bits, bytes, or their multiples (e.g., KB, MB, GB). It defines the maximum amount of program code or data the device can hold, directly determining its application scope in syst

Question 7

What is the Memory Type

Accepted Answer

This parameter specifies the fundamental technology and architecture used for data storage within an integrated circuit or module. It defines the core operational characteristics, including volatility, access method, speed, and endurance. Common types inc

Question 8

What is the Package / Case

Accepted Answer

Package / Case refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.

Question 9

What is the Product Status

Accepted Answer

Product Status indicates the commercial availability and production stage of the component, such as Active, Not for New Design (NRND), Obsolete, or Last Time Buy (LTB).

Question 10

What is the Write Cycle Time - Word, Page

Accepted Answer

This parameter specifies the time required to program data into non-volatile memory, with distinct values for writing a single word (typically a few bytes) and for writing a larger, contiguous block known as a page. The word write time defines the latency

Question 11

What is the Memory Interface

Accepted Answer

A standardized physical and electrical protocol defining how a processor or controller accesses and exchanges data with volatile (e.g., DRAM) or non-volatile (e.g., Flash) memory. Key specifications include data width, clocking scheme (e.g., SDR, DDR), co

Question 12

What is the Access Time

Accepted Answer

The delay between a valid address being presented to a memory chip's address pins and the corresponding data becoming available and stable at its output pins. This critical timing parameter, measured in nanoseconds (ns), defines the maximum latency for a

Question 13

What is the Operating Temperature

Accepted Answer

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the powe

Question 14

What is the Memory Organization

Accepted Answer

This parameter defines the internal architecture of a memory device, specifying how its total storage capacity is structured into addressable units. It is typically expressed as a product, such as "M x N" or "M words x N bits," where M represents the numb

Question 15

What is the DigiKey Programmable

Accepted Answer

A service offering that allows customers to configure specific parameters of a component (e.g., memory size, clock frequency, or firmware) at the point of order. This enables the manufacturer to produce a custom variant from a base product, providing appl

Question 16

What is the Voltage - Supply

Accepted Answer

The nominal DC potential difference applied to the power input pin(s) of an integrated circuit or module, measured in volts (V). It defines the required energy level for proper operation and establishes the reference for internal logic levels and analog s

Question 17

What is the Technology

Accepted Answer

This parameter specifies the fundamental physical principle, manufacturing process, or architectural approach that defines a component's core operation and construction. It determines key performance boundaries, such as speed, power efficiency, integratio

Question 18

What is the Mounting Type

Accepted Answer

Mounting Type refers to the standardized classification of the method by which an electronic component or module is physically secured and electrically connected to a printed circuit board, chassis, or panel. It defines how the component integrates into t

Question 19

What is the Memory Format

Accepted Answer

A standardized physical and logical structure for data storage, defining the arrangement of cells, access methods, and electrical interface. It dictates compatibility with host controllers and is fundamental for integrating storage into systems, with comm
