DS4520E Description

Short technical summary and product information.

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.
