Memory

X28HC256JI-90R5699 is a 256K-bit serial electrically erasable and programmable read-only memory (EEPROM) for high-speed microcontroller applications. It features a 3-wire serial I/O (SIO) interface for communication with a microcontroller or other system processor. It includes a 16-bit architecture for the address and data bytes.

Since X28HC256JI-90R5699 is a nonvolatile memory, it can store data even when powered off. This makes X28HC256JI-90R5699 suitable for applications where data needs to be kept even after power failure. Typical applications include automotive control systems, factory automation systems, industrial robot control, smart energy systems, medical equipment, home appliance control, and HVAC systems.

X28HC256JI-90R5699 is designed to quickly and reliably program, read, and erase data. It has an operating speed of 120 kHz and is designed to read data in 300 ns. It is designed to erase data of up to 64K bits with a single command. The X28HC256JI-90R5699 also features low power consumption for battery powered applications.

X28HC256JI-90R5699 is composed of three main components - control logic, I/O logic and memory cells. The control logic is responsible for decoding instructions from the microcontroller. Once decoded, the I/O logic handles communication between the microcontroller and the memory cells. The memory cells are where the data is stored.

When the microcontroller sends an instruction, the control logic decodes it and the I/O logic communicates with the memory cells. Depending on the instruction, data is either read, written, or erased. When data is written, the instruction notifies the memory cells to either place a 1 or a 0 into the specified address.

When data is read, the instruction notifies the memory cells to send the data stored in the specified address to the microcontroller. When data is erased, all the data in the specified address is set to 0. Erasing data can be done for individual addresses or for entire blocks of data.

X28HC256JI-90R5699 is a reliable memory component, suitable for many applications where data needs to be kept even after power failure. Its fast read and write speed, along with its low power consumption, make it suitable for high-speed microcontroller applications where battery powered operation is desired.
