µPac-535

This product is End-of-Life. Please contact our Sales Department for the recommended replacement or consider.

The MICROPAC series of Single Board Computers feature micro size with micro power consumption at a micro price. The MICROPAC 535 has dimensions of 5.375" by 3.675" with a power requirement of 45 ma. typical and 80 ma. with the upgrade option installed. The MICROPAC 535 is ideally suited for controller applications requiring an on board Liquid Crystal Display (LCD) and/or keypad interface circuitry.

Features

  • CPU: Infineon CMOS 80C535 with 11.0592 MHz. crystal speed.
  • DIGITAL I/O: 18 TTL level, bit programmable I/O lines, with an additional 3 input and 3 output lines available with the purchase of the upgrade option. The 24 I/O lines, 8 of which can be optionally configured as high drive outputs, terminate to a standard 50 pin I/O rack header connector.

  • COUNTER/TIMERS/PWM: Three, 16 bit counter/timers are included standard. One of these has four I/O lines which can be used as compare outputs, or capture inputs (for Pulse Width Modulation/Demodulation). A watchdog timer is also provided. An additional 16 bit counter/timer is included with purchase of the upgrade option.
  • COMMUNICATION: A total of 3 RS232 serial ports, 1 of which is standard and 2 of which are provided with purchase of the upgrade option. Conversion of any port from RS232 to RS422/485 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.
  • PERIPHERAL EXPANSION: The address bus, data bus, reset and interrupt lines are available on a 50 pin bus expansion header for connecting to external peripherals from EMAC, or to peripherals of your own design.
  • MEMORY: Memory space for up to 128K of EPROM/FLASH and up to 128K of RAM. Total memory capacity is 256K bytes.
  • DISTRIBUTION CD: A CD is included with a demo program in assembly language and both assembly and C drivers for the on-board peripherals.
  • THIRD PARTY SOFTWARE: The 80C535 is supported by Keil Software's C-compiler and their RTOS. A more economical DDS ANSI C subset compiler is also available as an alternative. There are C drivers for the on-board peripherals.

Overview

The MICROPAC series of Single Board Computers feature micro size with micro power consumption at a micro price. The MICROPAC 535 has dimensions of 5.375" by 3.675" with a power requirement of 45 ma. typical and 80 ma. with the upgrade option installed. The MICROPAC 535 is ideally suited for controller applications requiring an on board Liquid Crystal Display (LCD) and/or keypad interface circuitry.

The MICROPAC 535 Single Board Computer utilizes the Infineon 80C535 microprocessor. This high integration processor features an enhanced 8051 instruction set, programmable I/O ports, Boolean processor, interrupt controller, watchdog timer, A/D converter, Pulse Width Modulation, and timer/counters. You can think of this processor as being a next generation 8051.

EMAC integrated this powerful processor onto a board that contains up to 24 digital I/O lines, 3 serial RS-232/485 ports, EEPROM, LCD interface, keypad interface, 8 channels of A/D, and 4 channels of D/A.

The MICROPAC 535 comes complete with an 8051 assembler and complete driver source code written in assembly language on a PC compatible CD. A Monitor/Debugger EPROM that allows you to upload HEX files into RAM as well as a Flash Bootloader are optionally available. If you do not desire to program it in assembler, an optional EPROM containing BASIC 52 with high level drivers can be purchased as well as third party C compilers.

The MICROPAC 535 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.
