The MPC555 can be added to any PC/104 computer board. It provides 24 digital I/O lines, sixteen 12-bit analog input lines, and three 16-bit counter/timer channels that will operate from 40C to +85C. Eight user LEDs and four general-purpose readable jumpers are also included. An option adds eight 12-bit analog output lines. For many systems, this "combo" board will be the only add-on board needed. 
The analog input section of the MPC555 implements a complete data acquisition system, with software programmable full-scale ranges of +5V, +10V, 5V, and 10V. The digital I/O lines are TTL level, and can source and sink 2.5mA each. The counter/timer channels can be used to count digital input events, measure time between events, and generate system timing interrupts. The counter/timers are normally clocked by the PC/104 system clock, but can be clocked by a user-installed oscillator if a particular frequency is needed. The analog output options add 4 or 8 DACs with +10V full-scale outputs. Both analog inputs and analog outputs can support data rates to 100kHz. 
The MPC555 ships with full documentation and a diskette that has C language example programs for MPC555 operation. Source code is included for customization, if desired. A device driver for Linux is also provided. The MPC555 is $265 in single quantity. An industrial temperature (-40C to +85C) version is also available starting at $275. The 4 and 8 channel analog output options are $95 and $175, respectively. Significant OEM discounts are available.
