Victor, NY -- GCAT from DSP Design, the first commercially available
credit-card sized PC compatible is now available from The Saelig Company.
Measuring just 3.4" x 2.6" the card packs more functionality than you
would believe possible from a board this size, and will be of interest to
anyone who has previously been restricted by size, weight or power
consumption restraints.

At the heart of this remarkable product is the 14MHz F8680 PC/Chip
processor from Chips & Technologies - a high integration 16-bit CPU that
offers performance that compares favorably with the Intel 80286 or
80386SX. It has graphics hardware built in and will drive a CGA LCD screen
or CRT without using additional boards. The serial port is fully COM1
hardware compatible (can optionally be configured as RS485), and the board
has 1MB of DRAM and a 512K ROM disk capability as standard features. With
DOS and BIOS installed there is still about 400KB of application space
left for diskless applications.

Additionally, the GCAT has an on-board speaker, calendar clock, and
negative voltage generator for LCD screens. A PCMCIA memory card interface
is included so that removable memory media can be used without the need
for disk drives. This is configured to accept up to 256KB of SRAM and
256KB of Flash EEPROM, and all these memory types can co-exist
simultaneously if the application demands it.

One of the most important GCAT features is its surprisingly low power
consumption. Under normal conditions, the board consumes about 73ma from a
single 5v rail. However, in suspend mode, the consumption drops below
600ua (300ua with 3v supply).

Expansion to any I/O is via PCbus, so off-the-shelf I/O can be used if
required. A GCAT Development System is available, enabling users to
program the GCAT easily, and to use standard I/O cards. The Development
System combines dedicated Prototyping and Peripheral boards with a variety
of I/O connectors and a floppy disk drive. The aim of the system is to
encourage the developer to use the prototyping board to create custom I/O
in the same footprint as the GCAT, so that they stack together to form a
very compatct PC-compatible controller.

The GCATPB Peripheral Board contains the floppy disk controller, IDE hard
disk controller, bi-directional parallel port configured as a Centronics
port, and a second serial port that can be configured to RS485 (2 or 4
wire). A major part of the Peripheral Card is the inclusion of a 6 channel
12-bit plus sign A/D convertor (National Semiconductor LM12458). This
means you can store readings into a built-in FIFO and read when ready,
rather than regularly having to return to the A/D convertor to read each
channel individually (a process that MS-DOS does not excel at). With a
10us conversion time and alarm limits programmable on each channel, this
data acquisition unit is a very powerful tool.

The GCAT product range has been well thought out to meet the specific needs
of the OEM user and gives more power per square inch than any other
solution in the PC world. GCAT is the latest in a long line of
state-of-the-art microcontroller and high-integration PC-compatible
Eurocards that DSP Design has produced over the last ten years. The highly
integrated GCAT has many potential applications from palmtop personal
computers to embedded controllers in medical equipment and portable
instruments. It is available from stock at $799.
