Overview

The PCM-37E12 is a powerful Data Acquisition and Control I/O PC/104 module based on the Motorola 68HCS12 processor. Although being extremely powerful with ample I/O for demanding applications, this board consumes minimal power, is low cost, and has a small footprint. The PCM-37E12 uses the Standard PC/104 form factor (3.8" x 3.5") allowing the it to interface to any Single Board Computer that provides PC/104 connectivity.

Also available is an optional Screw Terminal board for the PCM-37E12 that is stackable, providing numerous I/O points with screw termination, in a very small package. Two Screw Terminal boards are required to accommodate all of the PCM-37E12 I/O.

The 68HCS12 coprocessor unit utilized on the PCM-37E12 is a 16-bit device composed of standard on-chip peripherals consisting of two asynchronous serial communications interfaces (SCI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), 29 discrete digital I/O channels, 16 discrete digital I/O lines with interrupt capability, and CAN 2.0 A, B software compatible modules.

EMAC integrated this powerful 16 bit processor onto a board which contains 32 digital I/O lines, 24 A/D inputs, 4 D/A outputs, 2 serial ports, CAN port, keypad interface, and an LCD interface. This is a do-it-all Data Acquisition module which could comprise up to 4 competitors PC/104 modules to duplicate the PCM-37E12's I/O capability.
