Introduction to CY7C1021D-10VXIT

CY7C1021D-10VXIT is an 8-pin, 10 MHz, dual-voltage, 256 Kbit I²C Buffer Non-Volatile Static RAM (NvSRAM) that functions as both a buffer non-volatile SRAM (Nv SRAM) and a stand-alone read/write non-volatile SRAM (NV SRAM). It provides a high-speed, reliable and low-power solution for data retention applications that require both a non-volatile memory and a fast, low-power buffer for data transfer.

CY7C1021D-10VXIT Memory Application Fields

CY7C1021D-10VXIT memory is widely used in embedded applications such as the following:

• Automotive infotainment systems,
• Industrial and consumer electronics,
• Medical and health devices,
• Printing and imaging,
• Security,
• Consumer appliances,
• Avionics,
• Entertainment,
• Telecom,
• Communication, and
• Machine control.

CY7C1021D-10VXIT is a low-power device which is suitable for high-volume and high-density applications. It provides fast data storage/retention performance and is also ideal for safety critical applications requiring memory retention and regular erasing/rewriting. The device can be easily connected to sensors or other interfacing devices, such as serial ports, audio interfaces and touch screens.

CY7C1021D-10VXIT Working Principle

The CY7C1021D-10VXIT uses a 3-wire serial interface. Data can be written to, and read from the memory with standard I²C commands. The device can be powered by a single voltage supply and can also be set up to operate in either a high or low speed I²C mode.

The device also comes with an internal clock generator which is an ideal feature for applications where there is no external clock available. Some applications may require that data be stored in a secure location. The device can be password protected and the memory can be write-protected to prevent accidental erasures of data.

The device has a write-protection mechanism that makes sure that data cannot be written to the memory without first writing the password. The device also has an enhanced power-down protection mechanism that ensures that data is safely retained when the device is powered down.

The device can store up to 256 Kbit of data, making it ideal for large data storage applications. It comes with an internal write-protection buffer, to ensure that data can be written and retrieved reliably.

The device has been designed with low power consumption and a very low standby voltage consumption so that it can be used in battery powered applications.

Conclusion

CY7C1021D-10VXIT is a high-speed, reliable and low-power memory solution which is well suited for data retention and data processing applications. It is suitable for a wide range of applications and provides fast read/write capabilities, secure data protection and low power consumption.
