UPD720102GC-YEB-A

UPD720102GC-YEB-A is an interface controller that enables high-speed communications between two electronic devices. It functions as a single-chip interface solution with two data lines and two control lines, allowing the transfer of signals between two components.

In applications, UPD720102GC-YEB-A is used as a bridge between two components that may use different communication protocols. It simplifies the connectivity process by providing a simple interface between two components and is especially useful in applications involving data transfer between two components with different protocols. Typical applications include transferring data between two different microcontrollers, two different memory devices, and two different processors. The UPD720102GC-YEB-A also has the capability to store data on the internal SRAM prior to communication.

Working principle

The UPD720102GC-YEB-A has a four-wire interface with two data/control wires (D/C) and two control wires (P/C). The controller contains a single internal SRAM for storing data before sending it out. When data is written via D/C line, it is first stored in the SRAM. After data is stored in the SRAM, it can be sent out via P/C line. The controller can also operate in the opposite direction, where the data can be sent via P/C line first, then stored in the SRAM before being sent out via D/C line.

In order to control data transfer in both directions, UPD720102GC-YEB-A has two separate ports, as mentioned above. P/C port is used to control data transfer from the external device to the internal SRAM, while D/C port is used to control data transfer in the other direction.The UPD720102GC-YEB-A controller also has several optional features, such as data rate support, synchronization support and error correction. These optional features provide more flexibility in applications where data rate control, synchronization or error correction is required.

In summary, UPD720102GC-YEB-A is an interface controller that enables high-speed data exchange between two electronic components. It operates by storing data in the internal SRAM and sending it out via two different ports. Optional features such as data rate support, synchronization support and error correction make UPD720102GC-YEB-A a very useful and versatile tool for data exchange between different components.
