Saelig Debuts Universal USB Controller with 50 I/O Pins

Pittsford, NY, USA: Saelig Company, Inc. (Saelig) ( has introduced IO-Warrior56 - a universal USB Controller that allows easy access to input or output functions via a USB bus. Featuring 50 generic I/O lines, IO-Warrior56 is also an I2C/SPI master, allowing interface with a wide range of available ICs.

IO-Warrior56 offers a simple access to the USB since it has been designed as a generic HID device - the protocol is all in the IO-Warrior56 chip. Only a few simple lines of code are needed to access the I/O pins. If you need to connect simple devices to a computer, like relays, switches, keypad, or a small display, IO-Warrior56 is a simple solution. Working with USB used to mean that you had to develop specific code for a USB-enabled microcontroller, developing a unique driver with lots of documentation, using expensive development systems. Now driving LCDs, LEDs, or keypads from USB is easy! IO-Warrior56 also supports a range of industrial standard interfaces such as I2C and SPI to simplify interfacing to chips, modules, or displays.

  • Full Speed USB2.0-compliant interface (12MBit/sec)
  • 50 general purpose I/O Pins, typ. 1000Hz rate (input or output)
