Memory

Memory is a class of electronic devices which are used to store data. The main types of memory are random access memory (RAM), read-only memory (ROM), and flash memory. AT28HC256E-90JU is a type of integrated circuit memory (also known as IC memory) which is used in many applications including embedded systems, digital signal processing, and smart card applications.

AT28HC256E-90JU is an 8-bit, 256Kbit, 5VCMOS EEPROM memory device designed for a wide range of applications. It is used in devices such as remote controls, digital cameras, and home appliances.

AT28HC256E-90JU has an optimized architecture which enables it to operate at maximum speed at minimal power. The device utilizes a single 5V supply and is organized as 32K words by 8 bits. There are three power-saving features incorporated into the chip - high temperature erase, low voltage erase and high voltage erase. In addition, the memory device includes a variety of features such as low power read, write enable, and data sheet access for fast and efficient operation.

In terms of application fields, AT28HC256E-90JU is largely used in embedded systems, where it is used as non-volatile memory. In this kind of application, the chip can be programmed using an industrial-grade programmer and the internal microcontroller will execute instructions automatically on power up. It is also used in a wide range of automotive applications such as body control module, dash-board control module, and in-car entertainment systems.

In terms of working principle, AT28HC256E-90JU is a non-volatile memory chip which stores data even when power is removed, thus allowing the device to retain its content while the memory is in operation. To write onto the memory device, a write pulse with a specific frequency is used to erase and write data into the selected memory location. Similarly, to read data from the device, a read cycle is used to access data stored in the memory. Note that this device does not require any special device programming prior to use; rather, it can be operated in a self-timed read cycle in which the address and data accesses automatically complete the read cycle.

At28HC256E-90JU is a robust and reliable memory device suitable for many applications. The device is relatively inexpensive, making it a cost-effective choice for many applications. With its optimized architecture and power-saving features, it is an excellent choice for memory-intensive applications.
