GPC® 81F

General Purpose Controller, Zilog 84C00

The GPC® 81F, an ultra powerful control module packaged on a standard EUROPE Single Size pcb (100x160 mm), is designed to operate on the similarly powerful ABACO® 16-bit industrial BUS, thereby exploiting a generous range of industrial peripherals.

The board is based on the Z80 family of CMOS technology CPUs and peripherals.

Basic frequency is 8 MHz, though a 10 MHz clock is also available.

Modular design renders the unit ideal for the construction of architectures with distributed logic, the resources afforded being advantageous in terms of I/O, and optimum as regards processing and memory.

With 512 Kbytes EPROM, in effect, the GPC®-81F is especially suitable for those applications where there is a need for a large quantity of code memory.

With powerful software packages available, the user can rapidly and conveniently develop all such programs as may be required for a given application, and using high level programming languages. Programming and exploiting the resources of this module is extremely easy thanks to the help of the stout GDOS Romated Operative System. This latter supports high level languages such as BASIC, PASCAL, C Compilers and so on.; it makes available the memory resources as they should be ROM/RAM-Disk allowing an immediate use of this devices at high level. This module linked to the MCI-64 and FGDOS manages PCMCIA cards of RAM cards and, directly, the on-board Peripherals as serial EEPROM. In addition to that the GPC® 81F allows a direct management of LCD or Fluorescent Displays. The FGDOS affords truly notable debug facilities, and allows to program directly on board a FLASH with the user program.

• EUROPE Single Size pcb measuring 100x160 mm; Interface to ABACO® Industrial BUS.
• CMOS Z80 chip, with 84C00 type 16 or 20 MHz quartz clock.
• 3 I/O ports controlled by PPI 82C55 assignable from software to give a total 24 input/output lines.
• Two RS 232 Serial lines controlled from SIO 84C44. One of which switchable to RS 422, RS 485 or Current Loop; communication protocol selectable via software, with transmission speed variable from 50 to 19200 Baud.

• 2K or 8K RAM with backup accessible in I/O, which can include a Real Time Clock giving time, hours, minutes, seconds, and date (day, month, year), naming day of the week.
• Watch-Dog, with selection of monostable and bistable operating modes and trigger time.
• Activity indicator LED with control from software, plus one set of board Status Indicator LEDs.
• Operating/Debug mode selector.
• 576K internal memory split as 512K EPROM or FLASH EPROM and 64K RAM. ROM operated as ROM disk, using FGDOS, with facility of Erasing and Programming FLASH EPROM directly in 16K sectors.
• Serial EEPROM with capacity 2 to 64K bit.
• CMOS technology applied throughout, bringing low power consumption.
• Single power supply: +5Vdc 150 mA.
• Wide range of developement software such as: Remote-Symbolic-Debugger, Macro Assembler, GET-80, BASIC Compiler, FORTH, C Compiler, DDS, HTC-80, NoICE, CBZ-80, PASCAL Compiler, CMX-RTX, etc. No development system required in order to operate; for example, the FGDOS package and a connection to any PC is sufficient.
