IDT7200L25SO8 Application Field and Working Principle

IDT7200L25SO8 is part of the IDT7200L series FIFOs (First In First Out) memories developed by Integrated Device Technology (IDT) for high-performance electronic systems. IDT7200L25SO8 is an SRAM-based device with a fast asynchronous FIFO structure. IDT7200L25SO8 is designed for controlling data flow between devices with different speed and control timing, providing complete independence between a transmitting device (write or output) and a receiving device (read or input). This ensures that high speed devices can transfer data streams to low speed devices that cannot keep up with the input clock.

Application fields of IDT7200L25SO8

IDT7200L25SO8 provides high-speed and low-latency asynchronous FIFO interfaces, which can be used in a variety of application scenarios including synchronizing and buffering data between two asynchronous sources, providing data flow control in complex systems, and performing communication protocol conversion. Therefore, IDT7200L25SO8 is ideal for applications such as communication products, like routers, DSLAMs, TP-MSANs and ATM switches, military-grade communication products, as well as product test systems, printer/copier/fax machines, thin-client/server applications, data validation/verification applications, high-performance data acquisition systems, high-speed ADCs/DACs and image processing systems.

Working Principle of IDT7200L25SO8

FIFO devices like IDT7200L25SO8 use a simple memory structure to store data that are constantly streamed from an output port to an input port. Data is usually streamed through a FIFO device known as WR (write), which sends data to an array of buffers. Each buffer is then read in a first-in first-out order by the RD (read) port. The data is thus read out of the memory in the same order in which it was written, hence the name “FIFO”.The IDT7200L25SO8 FIFO has two different ports, each with 8-bit wide data paths. It can store up to 2 kbytes of data, and can be configured to be full-duplex or half-duplex. It contains seven external control and two status signals, one chip enable signal(CE), one write enable signal(WE) and one read enable signal (RE).The IDT7200L25SO8 FIFO is designed to support wide range of data rates. It offers retransmission and alternate bus master options for dual port, full-duplex operation. Both ports are protected by parity circuits, parity select and parity detect inputs, and output enable.

Conclusion

IDT7200L25SO8 is a fast asynchronous FIFO memory developed by Integrated Device Technology. This memory is widely used in applications such as communication products, military-grade communication products, product test systems, high-performance data acquisition systems, high-speed ADCs/DACs and image processing systems. It is designed for controlling data flow between devices with different speed and control timing, and offers retransmission and alternate bus master options for dual port, full-duplex operation.
