The BQ4015MA-85 is a 256K x 8 static RAM integrated circuit (IC). It is a member of a family of bipolar static RAMs (SRAMs) manufactured by Texas Instruments and is used in a wide range of memory applications. It is intended for use in a variety of digital integrated circuits, including but not limited to: ASICs (Application-Specific-Integrated-Circuits), SoCs (System-On-Chip), and embedded-processor based systems.

The BQ4015MA-85 has a 8-bit wide chip organization and data output. The circuits are divided into 8-bit words and each word has a maximum size of 256Kbit. The BQ4015MA-85 also features random read and write capability, which makes it suitable for applications with variable amounts of data or for situations where data is updated frequently. It also features a low power/standby mode, meaning that it can be placed in a low power state when not being used, saving energy.

The BQ4015MA-85 has several application fields, such as memory for memory-intensive applications, like graphics, communications and media processing. It can also be used in system cache, ROM (read-only memory) for booting or storing system code or data, and as primary storage specified in embedded systems. The BQ4015MA-85 is ideal for low voltage applications due to its low power consumption capability.

The working principle of the BQ4015MA-85 is straightforward. The device has an internal control mechanism to manage the address and data lines between the memory and the integrated circuit. Each memory word includes 8-bits of data and is stored in a 256Kbit addressable array. When the device is enabled, it is transparent to the system, allowing data to be read or written to the memory just as if it were a normal memory chip. Data is read and written to the device via an addressable "write" and "read" addresses. It is possible to place the device into a low power/standby mode, which will reduce the power consumption of the device and also slightly reduce access times.

The BQ4015MA-85 is ideal for a variety of memory applications due its high-performance capabilities and low power mode. Its 8-bit Word organization, along with random read and write capability make it suitable for many data intensive applications. Its low power/standby mode is also a great feature that allows it to be used in low voltage applications. These features, combined with its availability in a wide range of packages, makes it an ideal choice for a variety of memory applications.
