DS4520 - I/O Expander Plus Memory

Description

The DS4520 is a 9-bit nonvolatile (NV) I/O expander with 64 bytes of NV user memory controlled by an I2Ccompatible 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.

Features

  • Programmable Replacement for Mechanical Jumpers and Switches.
  • Nine NV Input/Output Pins.
  • 64-Byte NV User Memory (EEPROM).
  • I2C-Compatible Serial Interface.
  • 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.
  • Wide Operating Voltage (2.7V to 5.5V).
  • Operating Temperature Range: -40°C to +85°C Ordering Information PART TEMP RANGE D.

DS4520 9-Bit I2C Nonvolatile I/O Expander Plus Memory General Description The DS4520 is a 9-bit nonvolatile (NV) I/O expander with 64 bytes of NV user memory controlled by an I2Ccompatible 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.
