expandIO-USBTM
Driver-free USB I/O expander for software-controlled peripherals
Summary
expandIO-USB is an ultra-low cost USB I/O expander.
It allows a PIC microcontroller to be remotely controlled
via USB, significantly reducing time-to-market for simple
USB-based products.
expandIO-USB provides control of most microcontroller
functions and is available for PIC18F14K50, LF2455,
and LF4455 microcontrollers.
expandIO-USB uses the Human Interface Device (HID)
USB profile. It does not require USB drivers and so is
immediately plug-and-play compatible with present and
future Windows, Linux and Mac operating systems.
expandIO-USB is supplied as HexWax firmware, or pre-
programmed and pre-configured microcontroller is larger
volumes.
USB Features
True HID plug and play - No drivers required
Ultra-low cost, single chip solution
Low speed version can use a low cost resonator,
200 commands per second
Full speed version can process up to 32K
commands per second
Product name, manufacturer name, serial
number, GUID & 122-byte EEPROM configurable
over USB
No Vendor ID / Product ID registration required
USB 2.0 compatible
USB / Self Power inputs
Optional Configured, Suspended and All-
Systems-Go, Tx / Rx indications
DIL, SSOP, TSSOP and QFP packages
