产品概述
DS4520E+TRL is a 9-bit non-volatile (NV) I/O expander with 64 bytes of NV user memory controlled by an I²C compatible serial interface. It offers users a digitally programmable alternative to hardware jumpers and mechanical switches that are being used to control digital logic nodes. Furthermore, the digital state of each pin can be read through the serial interface. Each I/O pin is independently configurable. The outputs are open drain with selectable pullups. Each output has the ability to sink upto 12mA. Since the device is NV, it powers up in the desired state allowing it to control digital logic inputs immediately on power-up without having to wait for the host CPU to initiate control. It is used in applications such as RAM-based FPGA bank switching for multiple profiles, selecting between boot flash, setting ASIC configurations/profiles, servers, network storage, routers, telecom equipment, PC peripherals.
- Programmable replacement for mechanical jumpers and switches
