The MICROPAC series of Single Board Computers feature micro size with micro power consumption at a micro price. The MICROPAC HC11 has dimensions of 5.375" by 3.625" with a power requirement of 45 ma. typical. The MICROPAC HC11 is ideally suited for controller applications requiring an on-board Liquid Crystal Display (LCD) and/or keypad interface circuitry.

Features


  • CPU: CMOS 68HC11F1 with 8.0 MHz crystal speed
  • DIGITAL I/O: 12 TTL level, bit programmable I/O lines, and 8 additional high drive (500 ma. sink, not to exceed package dissipation of 2.25 Watts) outputs. The 20 I/O lines terminate to a standard 50 pin I/O rack header connector.
  • ANALOG INPUTS: Fast 8 channel, 8 bit analog to digital converter with an 16 microsecond conversion rate.
  • ANALOG OUTPUTS: The optional D/A has 4 channels with 8 bit resolution.
  • COUNTER/TIMERS/PWM: 1, 16 prescaled counter featuring 4, 16 bit output compare registers, and a bi-directional input/output register providing PWM capability. An 8 bit counter/timer is also available. A Watchdog Timer is also included
  • COMMUNICATION: A total of 2 RS232 serial ports, 1 of which is standard and 1 of which is optional. Conversion of one port from RS232 to RS-422/485 is available optionally.
  • INTERFACES: A Backlit LCD interface is provided standard with an optional 20 key, keypad interface available. Also included is a 50 pin bus expansion header.

Overview


The MICROPAC series of Single Board Computers feature micro size with micro power consumption at a micro price. The MICROPAC HC11 has dimensions of 5.375" by 3.625" with a power requirement of 45 ma. typical. The MICROPAC HC11 is ideally suited for controller applications requiring an on-board Liquid Crystal Display (LCD) and/or keypad interface circuitry.

The MICROPAC HC11 Single Board Computer utilizes the Freescale 68HC11F1 microprocessor. This high integration processor features programmable I/O ports, Boolean processor, interrupt controller, watchdog timer, A/D converter, pulse width modulation (PWM) capability, EEPROM and timer/counters. The F1 is the most powerful processor in the 68HC11 processor family.

EMAC integrated this powerful processor onto a board that contains up to 20 digital I/O lines, 2 serial RS232/485 ports, LCD interface, keypad interface, 8 channels of A/D and 4 channels of D/A. This is a do-it-all Single Board Computer.

The MICROPAC HC11 comes complete with an 68HC11 assembler on a PC compatible disk and a Buffalo Monitor EPROM that allows you to upload HEX files, single step through code, dump memory, and more. Complete commented driver source code, written in assembly language is also included. If you do not desire to program it in assembler, an optional EPROM containing BASIC 11 with high level drivers can be purchased as well as a number of third party C compilers.

The MICROPAC HC11 is ideal for low cost data acquisition and control applications that require a display and keypad entry. The 8 channels of A/D allow the board to be connected to temperature sensors, pressure sensors, strain gauges, and LVDTs. Conditioned signals from these sensors can be used to make decisions in controlling motors, lights, heaters, etc. Try this board in your application for 30 days risk free!
