The DS4520E+TRL from Analog Devices is a versatile 9-bit nonvolatile (NV) I/O expander designed to replace mechanical jumpers and switches. It offers a digitally programmable alternative for controlling digital logic nodes, with each I/O pin independently configurable. The device features an I2C-compatible serial interface, allowing up to 8 devices to be multidropped on the same bus.
Key electrical specifications include a wide operating voltage range of 2.7V to 5.5V and an operating temperature range of -40°C to +85°C. The outputs are open-drain with selectable pullups and are capable of sinking up to 12mA. The expander includes 64 bytes of NV user memory (EEPROM) and powers up in a desired state, enabling immediate control of digital logic inputs without host CPU intervention.
This I/O expander is suitable for applications such as RAM-based FPGA bank switching, selecting between boot flashes, and setting ASIC configurations. It is supplied in a 16-TSSOP surface-mount package, making it ideal for space-constrained designs. The device operates at a clock frequency of up to 400 kHz.
