The AT27C2048-70JC is a type of electronically-erasable programmable read-only memory (EEPROM) integrated circuit (IC) manufactured by Atmel. It is an 8-Kbit device with a wide range of applications in commercial, industrial, and consumer systems. This type of memory has become increasingly popular due to its high speed, small size, and cost-effectiveness.

The AT27C2048-70JC is primarily used in application fields where the ability to store data and program preferences is critical. It is widely used in consumer electronics products such as TV sets, digital cameras and digital music players. It is also used in industrial control and automotive systems in order to store settings and parameters that need to be changed on a regular basis. It is also widely used in industrial automation systems, where performance and reliability are paramount.

The AT27C2048-70JC features a 256 x 8-bit nonvolatile memory array. It has an extended temperature range of -40 ^oC to +85 ^oC and a wide voltage range from 8V to 25V. It has a low current consumption and normal cycling time of 5 ms. The device can be electrically erased, then programmed using a standard 5V programming voltage and fast programming algorithms.

Data is stored in the AT27C2048-70JC using a type of non-volatile memory cell called a floating gate transistor. This type of memory cell consists of two transistors, which are connected in series between two capacitors. A voltage is applied to the gate of the first transistor, which, in turn, controls the flow of current through the second transistor. The capacitors act as storage units, retaining the gate voltage and thus the data even when the device is powered off.

The AT27C2048-70JC has three major control signals. The CE pin is used to select the device and enable read and write operations. The OE pin is used to enable the output buffer and to provide access to the contents of a selected address. The WE pin is used to control write operations.

The AT27C2048-70JC is one of the most widely used EEPROMs due to its flexibility, cost-effectiveness, and reliability. It is designed for a number of applications and is suitable for use in a variety of systems. It is a versatile memory solution that can easily be integrated into any system.
