The AT28C010-20JI is a 1-megabit (128K × 8-bit) CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) that is well suited for a variety of applications. It is a low-power device that can be used in almost any memory application, from automotive and industrial controls to consumer products. This article will discuss the application field and working principle of the AT28C010-20JI.

Application Field

The AT28C010-20JI is well suited for applications that require reliable non-volatile memory storage. It is commonly used in automotive and industrial controls, consumer products, communications systems, industrial and office automation, medical equipment, computer peripherals, data gateways, embedded microcontrollers, programmable logic controllers, etc. Typical applications include the storage of parameters, system codes and software, or other data that needs to be stored.

The AT28C010-20JI is particularly well suited for automotive and industrial applications. The device is designed to operate over an extended temperature range, and it is also highly reliable with a low probability of data retention failure. Additionally, the device is RoHS compliant and has a low-power design that is compatible with automotive and industrial environments.

Working Principle

The AT28C010-20JI is a CMOS EEPROM which uses an array of floating gate transistors to store data. A floating gate is an electrically isolated conductor that can be charged or discharged in order to store a bit of data. The device can be programmed and erased electrically, and data can be stored for many years.

Programming is accomplished by applying a particular programming voltage to the memory cell. The voltage ionizes the channel of the transistor and allows electrons to be injected into the floating gate. An erase cycle can then be used to remove the charge from the floating gate. This process allows the device to be reprogrammed many times, up to a maximum of 10,000 write cycles.

The AT28C010-20JI also features a number of safety features to protect the data stored in the device. For example, the device is equipped with a Write Inhibit (WIC) circuit which prevents accidental writes and erasing of the memory. The device also features a number of write protect pins that can be used to prevent programming of certain sections of the device.

In addition to its many safety features, the device also offers a wide variety of configuration options. The device can be configured for up to four different 32K word blocks and can be configured to access data as either static or dynamic memory. The device also supports both slow and fast programming and erase times, as well as a Sleep mode which enables the device to operate at minimum power consumption.

The AT28C010-20JI is a versatile EEPROM device which is ideal for a variety of applications. Its low-power design and wide range of configuration options make it a great choice for automotive and industrial applications, as well as in many other memory applications.
