The X28HC64D-90 is a 64K dynamic random-access memory (DRAM) chip from Intel. It is a low-power memory chip with a maximum power dissipation of 350 mW. The X28HC64D-90 is a synchronous 4Mb dynamic random access memory (DRAM). It can be arranged in a 64-bit or 32-bit data bus configuration and is an ideal memory solution for embedded systems and applications that require high performance.

The X28HC64D-90 is designed to provide high performance and low power consumption when operating in a high-speed read-write memory environment. It features a three-phase clock system, with a 500 MHz maximum clock frequency and advanced controller-specific logic. The chip also features an on-die register set. This feature makes the X28HC64D-90 ideal for applications where high data throughput is required.

The X28HC64D-90 provides a reliable and efficient means of storing data in an environment where fast access and write times are essential. The chip is designed to be used in conjunction with a controller and can operate as a standalone memory device. It also offers a programmable interface, as well as support for a wide range of access methods, including DMA, programmed I/O, and interrupts.

The chip provides data retention, which means that data stored in the chip can be preserved for a long time even when the power is removed. The chip is also capable of resetting itself when the power is restored. This allows for very low power consumption during periods of inactivity or in the event of a power failure.

In terms of its working principle, the X28HC64D-90 is a synchronous dynamic random-access memory (DRAM) device. It works by consolidating the data into a series of memory cells. Each of these cells is then separated into two parts: the control gates and the access gates. The control gates are responsible for controlling address and data signals while the access circuit is responsible for the read and write operations.

The X28HC64D-90 is designed to provide low power consumption and a high level of performance. It is used in a wide range of embedded applications, including industrial automation, automotive, consumer electronics, and communications systems. The chip is used in many mission-critical systems, and it has been used in some of the most sophisticated and complex designs.

In summary, the X28HC64D-90 is a 64K dynamic random-access memory (DRAM) chip from Intel. It is a low-power memory chip with a maximum power dissipation of 350 mW. It is a synchronous device with a 500 MHz maximum clock frequency and an extensive register set. It is used in embedded systems and applications that require high performance and low power consumption. The chip features a three-phase clock system, data retention, and a wide range of access methods.
