The DS4520E from Analog Devices is a 9-bit nonvolatile I/O expander designed as a programmable alternative to mechanical jumpers and switches. It features an I2C-compatible serial interface and includes 64 bytes of nonvolatile user memory.
This device offers independently configurable I/O pins with open-drain outputs and selectable pullups, capable of sinking up to 12mA. It operates over a wide voltage range of 2.7V to 5.5V and maintains functionality within an operating temperature range of -40°C to +85°C. The DS4520E powers up in its desired state, allowing immediate control of digital logic inputs without host CPU intervention.
Applications include RAM-based FPGA bank switching, boot flash selection, and setting ASIC configurations. The DS4520E is supplied in a 16-TSSOP package, suitable for surface mounting. Its clock frequency is up to 400 kHz.
The operating voltage range is 2.7V to 5.5V.
The operating temperature range is -40°C to 85°C.
The DS4520E is available in a 16-TSSOP package.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level is 1 Unlimited.
The clock frequency is 400 kHz.
The output type is Open Drain.
