Product Overview

The DS4550E+ is an I2C and JTAG non-volatile 9bit I/O expander plus memory in 20 pin TSSOP package. It is a 9bit, non-volatile (NV) I/O expander with 64bytes of NV user memory controlled by either an I2C-compatible serial interface or an IEEE 1149.1 JTAG port. The DS4550 offers a digitally programmable alternative to hardware jumpers and mechanical switches that are being used to control digital logic nodes. Each I/O pin is independently configurable. The outputs are open drain with selectable pull-ups. Each output has the ability to sink up to 16mA and 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. Typical applications include RAM based FPGA bank switching for multiple profiles, selecting between boot flash, setting ASIC configurations/profiles, servers, network storage, routers, telecom equipment and PC peripherals.
  • Supply voltage range is 2.7V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Programmable replacement for mechanical jumpers and switches
  • Nine NV inputs/outputs
  • Up to 8 devices can be multidropped on the same I2C bus
  • Low power consumption
