9-Bit I C Nonvolatile  
I/O Expander Plus Memory  
General Description  
Features  
♦ Programmable Replacement for Mechanical  
The DS4520 is a 9-bit nonvolatile (NV) I/O expander with  
64 bytes of NV user memory controlled by an I2CTM  
-
Jumpers and Switches  
♦ Nine NV Input/Output Pins  
♦ 64-Byte NV User Memory (EEPROM)  
♦ I2C-Compatible Serial Interface  
compatible serial interface. The DS4520 offers users a  
digitally programmable alternative to hardware jumpers  
and mechanical switches that are being used to control  
digital logic nodes. Furthermore, the digital state of each  
pin can be read through the serial interface. Each I/O  
pin is independently configurable. The outputs are open  
drain with selectable pullups. Each output has the ability  
to sink up to 12mA. Since the device is NV, it powers up  
in the desired state allowing it to control digital logic  
inputs immediately on power-up without having to wait  
for the host CPU to initiate control.  
♦ Up to 8 Devices Can be Multidropped on the  
Same I2C Bus  
♦ Open-Drain Outputs with Configurable Pullups  
♦ Outputs Capable of Sinking 12mA  
♦ Low Power Consumption  
Applications  
RAM-Based FPGA Bank Switching for  
Multiple Profiles  
♦ Wide Operating Voltage (2.7V to 5.5V)  
♦ Operating Temperature Range: -40°C to +85°C
