72245LB10PFG

72245LB10PFG is an application field memory used in communication systems, security and consumer electronics. It is a dual-ported static random access memory (SRAM) device with a non-volatile write option, providing the security that data and application code remain retained during power-down periods.

The 72245LB10PFG, like other FIFOs (First In-First Out) Memory products has two ports, the write and the read ports. The write port is used to store the incoming data and the read port retrieves the data stored in the memory. The two-port architecture allows for simultaneous read and write operations, making it suitable for a variety of applications, but especially for those which require the implementation of data buffering. The memory includes 10 addressable registers, for a total of 256 words of 32-bit storage.

In terms of working principle, the 72245LB10PFG allows the user to write data to the memory and then time-stamp it upon write, with up to 8-bit time-stamps. The time-stamps ensures that the FIFO can be read in the order it is written, allowing for increased throughput when retrieving data from the memory device.

The device also includes write protection and read move functionality, allowing it to be used as a secure memory for protecting application code and data. The write protection functionality is enabled by setting the FIFO to write enable, preventing accidental writes and data corruption. This feature combined with the read-move option, enhances the security of the application data, as it requires the user to explicitly set the memory to read-move before any data can be moved from the FIFO.

Moreover, 72245LB10PFG operates at low power with a typical active power consumption at 2.2 W and an idle current consumption at 0.2 μA. This power consumption makes it effective for use in power-sensitive applications. It is available in an industrial temperature range of -40°C to +85°C.

In conclusion, the 72245LB10PFG is an ideal static memory device for storing data safely and managing read requests in security, consumer and communication applications. The write protection and the read move features make it suitable for use in secure applications and its low power consumption makes it a power-efficient choice.
