The iPac HCS12 is a powerful Single Board Computer (SBC) based on the Freescale 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 iPac HCS12 uses the Standard PC/104 form factor (3.8" x 3.5") allowing the use of standard PC/104 mounting hardware and enclosures.

Also available is an optional Screw Terminal board for the iPac (shown above) 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 iPac I/O.

The 68HCS12 microcontroller unit (MCU) used on the iPac is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit,128K bytes of Flash, 8K bytes of RAM, 2K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), two serial peripheral interfaces (SPI), 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, 20 discrete digital I/O lines with interrupt and wakeup capability, and CAN 2.0 A, B software compatible modules.

EMAC integrated this powerful 16 bit processor onto a board which contains 48 digital I/O lines, 24 A/D inputs, 6 D/A outputs, 2 serial ports, CAN port, Real Time Clock, keypad interface, and an LCD interface. This is a do-it-all Single Board Computer.

The resident flash on the iPac can be programmed via it's serial bootloader firmware over the RS232 com port or via it's BDM port. Software can be written with Cosmic Software's HC12 paged compiler or the Free GNU compiler located at:

ftp://m68hc11.serveftp.org/pub/m68hc11/gnu/.

For more information on 68HC12 GNU tools go to: http://m68hc11.serveftp.org/blog/.

EMAC provides Driver object files and Demo application source code usable by the free GNU or Cosmic compilers, allowing the user to quickly develop custom applications. Programs developed in this manner can download over the provided serial bootloader at no extra cost to the user other than the original purchase of the hardware.
