The IS65C256AL-25ULA3 devices are low-cost memories designed specifically for low power applications. The IS65C256AL-25ULA3 devices are constructed with CMOS technology, offering power saving circuit design techniques and extremely low power consumption. These devices consists of 256K bits (32K words by 8-bits) of non-volatile memory organized into 8 non-volatile RAM registers of 32K words. They feature quick random read access times as low as 25ns with a maximum power consumption of 25mA. They also feature on-chip power-down, write protection and write enable functions.

The IS65C256AL-25ULA3 memories are suitable for applications such as controller core memories, printer controllers, set top box memory, automotive infotainment, radio receivers and other small embedded systems requiring an extremely low power consumption and high performance. They are also well suited for applications involving frequent write operations, such as digital video and audio devices. Also, they are designed to provide a user-friendly development environment with a wide selection of tools, libraries and source code modules.

The IS65C256AL-25ULA3 memory works by utilizing the CMOS technology, the core technology used in the fabrication of integrated circuits. CMOS stands for Complementary Metal Oxide Semiconductor and is a major form of digital logic circuitry which has the advantage of requiring lower power consumption, higher speed and has a smaller footprint. The core features of the IS65C256AL-25ULA3 memory are provided by the on-chip write protection, write enable, and power-down control. The on-chip write protection includes a 3-bit write protect register that allows for write protection of specified word banks. The on-chip write enable feature provides a 5-bit write enable register to enable or disable writing of specified word banks.

The on-chip power-down control provides low power consumption through the use of fast triggers, power sequence detectors, and current of supply control. When active, the IS65C256AL-25ULA3 memory uses a maximum of 25mA at 3.3V and can be powered down to 0.25mA when inactive. During write operations, the device outputs a write strobe signal to indicate when writes are enabled and disabled.

In summary, the IS65C256AL-25ULA3 memory is an extremely low power consumption memory device with an on-chip feature set for low power operation and quick access times. Its features make it well suited for applications that require frequent write operations and fast read access times. Its low power consumption and quick access times make it well suited for controller core memories, automotive infotainment systems, audio and video devices, and other embedded systems. Its on-chip features make it easy to develop and code for, adding to its utility in embedded systems applications.
