DS4550E+ Description

Short technical summary and product information.

The DS4550E+ from Analog Devices is a versatile 9-bit, nonvolatile I/O expander designed to replace mechanical jumpers and switches. It provides 64 bytes of nonvolatile user memory and can be controlled via an I2C-compatible serial interface or a JTAG port.

 

Key features include independently configurable I/O pins with selectable pullups, capable of sinking up to 16mA. The device powers up in its desired state, allowing immediate control of digital logic inputs without host CPU intervention. It operates over a wide voltage range of 2.7V to 5.5V and a temperature range of -40°C to +85°C.

 

Applications for the DS4550E+ include RAM-based FPGA bank switching, selecting between boot flashes, and setting ASIC configurations. It is suitable for use in servers, network storage, routers, telecom equipment, and PC peripherals. The device is available in a 20-TSSOP package.
