Memory: AT27C512R-90JI Application Field and Working Principle

AT27C512R-90JI (hereinafter referred to as \'AT27\') is an advanced memory component used in a range of applications across different industries. AT27 memory components are used in computing to store data, as well as in electronic and industrial applications.

The AT27 component is a type of CMOS electrically erasable programmable logic device (EEPLD). This component is a 128K-word memory component, which uses the Erasable Programmable Read Only Memory (EPROM) technology for data storage. It has a storage capacity of 16,777,216 bits and is organized as 2048 words of 8 bits each.

AT27 Features

The AT27 has several features that make it an ideal choice for advanced electronic and industrial applications. These features include:

• High speed access time: 125 ns
• High speed data rate: 100 MHz
• Low power consumption: 500 µW
• Extended temperature range: -40°C to +125°C
• Automatic write protection when powered off
• Wide range of languages supported: English, French, German, Spanish, and Dutch

Working Principle

The working principle of the AT27 memory component is based on electrical charge stored on an insulating material. A high-voltage electrical pulse is applied to the component to write a \'1\' or a \'0\' bit, depending on the type of access that is needed. When the voltage drops, the charge is retained and can be read back by applying a lower voltage pulse.

The AT27 is capable of performing single or multiple read and write operations in the same chip. It also allows for partial read and write operations, in which only certain parts of the memory array are written or read. This feature enables the AT27 to be used for complex application fields, where more precise data manipulation is required.
