CY7C1265V18-400BZC is a 256Kx18 high-speed CMOS static RAM. The CMOS static RAM has high integration characteristics and low power consumption, making it suitable for applications where operating temperature, operating voltage and power consumption are tight. The CY7C1265V18-400BZC chip features 18-bit wide access and low pin count, making it ideal for a wide range of use.

In the memory field, CY7C1265V18-400BZC is mainly used as a high-speed embedded RAM for digital signal processing, real-time control, and multimedia applications. This chip is suitable for applications with high speed operation, long standby time, and strong air defense. More importantly, it needs to meet the needs of high-definition images and 3D graphics. In addition, it can also be used in data storage, buffering, and memory expansion.

In terms of working principle, CY7C1265V18-400BZC is composed of eight sectors of 256K synchronous RAM. Each sector contains decoding circuits, data output and access control circuits, data input and decoding circuits, and data memory cells. All elements are interconnected by a 16-bit multiplexed address input/output control circuit. After power is turned on, the contents of RAM will be reset. When the operation control clock is provided, each sector will be activated according to the address codes. The selected sector will read or write data, store or access RAM operation register, and execute the command operations.

In order to make the chip enter the stand-by state to reduce its power consumption, the data chips use the built-in power-down mode. In this mode, all data pins are disconnected from the external bus, data input and output pins are taken over, and the command pin is internally disabled. At this time, the power consumption of the chip is about 1/3 of the normal operating condition. When the chip is out of standby mode, the chip will recover its normal operating state, which is convenient for flexible control and optimized system.

In summary, the CY7C1265V18-400BZC chip is in line with the current memory requirements, widely used in digital signal processing, real-time control, multimedia applications and other fields, with high speed, power saving, strong air defense and other advantages. Compared with other chips, its performance is not compromised, making it a ideal choice for the application field.
