X28HC256JIZ-90T1

Memory

X28HC256JIZ-90T1 is a type of memory chip used for data storage. It is a non-volatile memory chip, meaning that it can store data even when there is no power present. It is used in a wide variety of applications ranging from consumer electronics, to automotive, to industrial applications.

The X28HC256JIZ-90T1 is organized into 8 blocks of 64K of 8-bit memory each. The chip can be configured either as 32K x 8 or 64K x 8 with either two or four blocks enabled, depending on the application. The chip also includes an on-board Power-On Reset circuit as well as an Auto-Refresh circuit providing automated data backup.

The X28HC256JIZ-90T1 has an 8-bit data bus and address bus, allowing for the transfer of 8 bits of data between the chip and the rest of the system. The chip also has a serial data input and output port, allowing for the chip to be programmed or programmed data to be retrieved externally.

The X28HC256JIZ-90T1 is a relatively low-cost solution for data storage and provides some of the flexibility of a more expensive EEPROM chip. It is also quite energy efficient and can be used in battery operated applications. This makes it a great choice for applications such as embedded systems, automotive, and industrial applications.

The working principle of the X28HC256JIZ-90T1 is relatively simple. The chip stores data in 8 bit segments and operates on 8 bit commands. Commands are sent to and from the chip on the data and address buses. The chip can be programmed or read through the Serial Data Input (aka SPI) and Serial Data Output (aka SDP) ports. Access to the chip is controlled by the chip\'s Chip Select (CS) and either the Chip Enable (CE) or the Program Enable (PE) inputs.

The X28HC256JIZ-90T1 is a robust and reliable memory solution and is used in a wide variety of applications. It can store up to 64K of data, which makes it ideal for applications needing to store large amounts of data. The chip is relatively low-cost, energy efficient, and can be used in battery powered applications, making it a great choice for embedded, automotive, and industrial applications.
