Analog, Digital, and Timer I/O for PC/104 MPC555 Features Sixteen 12-bit channels of analog input 100kHz A/D sampling rate Software selectable A/D input ranges 24 digital I/O lines 4 Input Jumpers and 8 LEDs Three 16-bit counter/timers Optional 12-bit DACs, 4 or 8 channels 5V-only operation PC/104 form factor Extended temperature operation available The MPC555 Analog and Digital I/O module ranges. The input ranges supported can be provides 16 channels of analog input to PC/104 either unipolar or bipolar. Ranges available are systems that run high or low speed CPUs. The +5V, +10V, ±5V, and ±10V. module also includes 24 bits of digital I/O, 4 general-purpose input jumpers, 8 user LEDs, The three 16-bit counter/timer channels can be and three general-purpose counter/timers. Addi- used to count digital input events, measure time tionally, up to 8 channels of analog output are between events, and generate system timing available. interrupts. The counter/timers are normally clocked by the PC/104 system clock, with options The analog input section implements a complete for a user-supplied oscillator if a particular fre- data acquisition system with programmable input quency is needed.
