AT28C010E-15JU-235 Application Field and Working PrincipleIntroductionThe AT28C010E-15JU-235 is an EEPROM (Electrically Erasable Programmable Read-Only Memory) organized as a1024-word by 8-bit device. It is often used as an economical replacement for EPROM (Erasable Programmable Read-Only Memory). This memory device provides a nonvolatile memory to store data and code. It is available in a 20-lead dual in-line package (DIP).Application FieldThis device has become a popular memory component in many applications, such as the embedded system, telecommunications, instrumentation, automotive electronics, and consumer electronics.In the embedded system, AT28C010E-15JU-235 is capable of storing the control programs which are reprogrammable to accommodate different types of microcontrollers. Moreover, it allows the controller to make decisions on how to control the system’s operations based on the information stored in its memory.In telecommunication, AT28C010E-15JU-235 is frequently used for the storage of telephone numbers, installation data and system default settings. The memory component helps to store the large amount of data required for network operations and to further reduce transmission delays.In instrumentation, it helps to store diagnostic information and can provide self-education and self-calibration.In automotive electronics, it provides a reliable way to store critical information, such as engine control parameters, serial numbers and safety information.Furthermore, in the consumer electronics, AT28C010E-15JU-235 is widely used for storing the settings of digital products such as television and audio devices.Working PrincipleAT28C010E-15JU-235 works as a nonvolatile memory, which means it can retain the stored data even if the power is removed. It operates on a single 5V power supply and draws nominal supply current of 350µA active and 1µA standby.On top of the chip, there are Data Input/Data Output (I/O) buffers for transferring data between the memory and external systems. There is also an 8-bit latch, which works as a temporary storage during the data write operation. The Chip Enable (CE), Output Enable (OE) signals are responsible for enabling the data transfer between external components. The Write Enable (WE) signal is used to initiate the write operations on the device.The data write operation begins when the Write Enable signal is enabled and continues until the Write Protect pin (WP) is disabled. When the WP pin is enabled, all write operations are blocked and disabled. The data read operation can be started when the CE and OE signals are enabled. The data output is available on the data output pins (DQ) as soon as the read operation is completed.ConclusionAT28C010E-15JU-235 is a widely used EEPROM device in many applications, such as the embedded system, telecommunications, instrumentation, automotive electronics, and consumer electronics. It provides a nonvolatile memory for storing data and code and requires a single 5V power supply for operation. Its main components are the Data Input/Data Output (I/O) buffers, the 8-bit latch, the Chip Enable (CE) and Output Enable (OE) signals and the Write Enable (WE) signal. Its write operation begins when the Write Enable signal is enabled and continues until the Write Protect pin (WP) is disabled. Its data read operation can be started when the CE and OE signals are enabled. AT28C010E-15JU-235 memory is a reliable and economical device for storing data and code.
