The DS4520E+ from Analog Devices is a versatile 9-bit nonvolatile (NV) I/O expander designed to replace mechanical jumpers and switches. It utilizes an I2C-compatible serial interface for control and configuration, allowing digital states of each pin to be read. The device includes 64 bytes of NV user memory (EEPROM) and supports up to 8 devices on the same I2C bus.
Key electrical features include open-drain outputs with selectable pullups, capable of sinking up to 12mA. It operates from a wide supply voltage range of 2.7V to 5.5V and maintains functionality across an industrial temperature range of -40°C to +85°C. The integrated nonvolatile memory ensures the device powers up in the 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 housed in a compact 16-TSSOP package, suitable for surface mount applications. The DS4520E+ is an efficient solution for simplifying digital logic control and configuration in various electronic systems.
The operating voltage range is 2.7V to 5.5V.
The DS4520E+ is available in a 16-TSSOP package.
The operating temperature range is -40°C to +85°C.
The RoHS status is RoHS3 Compliant.
The DS4520E+ has 9 I/O channels.
The DS4520E+ uses an I2C interface.
The outputs of the DS4520E+ are capable of sinking up to 12mA.
