CY62147EV30LL-45BVI

The CY62147EV30LL-45BVI is a high performance non-volatile memory device manufactured by Cypress Semiconductor that is specifically tailored for applications needing highly reliable data storage. It is a 1.8V, 45nm 5Kb embedded ferroelectric random access memory (FRAM) device with 22-bit programmable width addressing, optimized for low power operation, and taking two-phase 4MHz clock input. It has 30MHz maximum operating frequency, with a typical write current of less than 1mA and a typical read current of less than 0.6mA. In addition, the device features low operatingvoltage, low refresh current, and high data retention capabilities.

As its name implies, the CY62147EV30LL-45BVI is a highly reliable device for storing data for extended periods of time. It offers fast write and read speeds with minimized current consumption, making it suitable for applications that require frequent exchanging or updating of information, such as automotive, avionics and medical electronics. In addition, it has a minimum data retention of 10 years, ensuring that stored data is kept securely for long periods of time.

In terms of operation, the CY62147EV30LL-45BVI is divided into two main parts: the main control block and the FRAM control module and data buffer. The main control block consists of a 22-bit address decoder and a state machine that handles program and data execution. Its primary function is to decode the input address signals, fetch data from the FRAM modules, execute instructions, and store data back into the FRAM modules.

The FRAM control module and data buffer transports the data between the main control block and the FRAM. Its primary function is to write and read data to and from the FRAM cells. The FRAM control module also has a data buffer that is used for storing and transferring data between the internal RAM and the FRAM. The data buffer is divided into two sections; the input buffer used for writing data to the FRAM cells, and the output buffer used for reading data from the FRAM cells.

The CY62147EV30LL-45BVI also comes with a built-in NOR flash memory that can be used for storing code and other information. This NOR flash memory is accessed via the FRAM control module, allowing for fast and efficient access to stored data. The NOR flash memory also has a built-in high-speed SRAM that can be used for storing data and executing complex algorithms.

The CY62147EV30LL-45BVI is an ideal choice for applications that require high data security, fast read and write speeds, and low power consumption. Its 22-bit programmable width address mode allows for easy programming and access of data, and its low power consumption ensures that it can operate for extended periods of time without any significant impact on battery life. Together with its high data retention capabilities and NOR flash memory, the CY62147EV30LL-45BVI is an excellent choice for a wide range of applications that require high performance and reliable data storage.
