PC/104 Small Computer Cards

Embedded applications require specific features difficult to find on commercial PC main boards.
Creating a custom made board with desired features is expensive and time consuming.
A simpler and more cost effective solution is to add features by incorporating PC/104 modules.
PC/104 modules use a smart stacking bus design that allows you to expand the system by simply adding additional modules.

PCM-3346  486 CPU Module with LCD & Ethernet

The PCM-3346, has all the functions and power of a standard full-size PC applied into the form factor of an industry standard PC/104 (90 x 96 mm).

Even though this module is so small, it still contains everything that a full-fledged computer requires.
Advantech took its industry-proven PCM-3345 486-based PC/104 CPU module and
added an on-board LCD controller (C&T69000) as well as 10/100Base-T Ethernet.
The on-board LCD controller supports 36-bit video and has 2 MB display memory on chip.
These features give our customers a small, complete and cost-effective board solution for
applications that require network and LCD panel support in a limited space environment.

This module supports Watchdog timer protection.
There are two serial and one parallel ports,
one FDD connector and one IDE connector, allowing for as much peripheral expansion as most much larger size SBCs.
This board also supports one CompactFlashTM card for use as an emulated HDD.
Its on-board CPU is a 486 DX 66 MHz equivalent from ST Thompson (STPC).
It is unique for a 486-based CPU in that its front side bus runs at 66 MHz, instead of only 33 MHz like Intel® 486 CPUs.
Also, since it's integrated on board, there is no need to configure CPU frequency or voltage.
It supports 16, 32 and 64 MB EDO SODIMM (Small Outline DIMM: EDO 144 pin 3.3V).
Power requirements: +5V 2.17A typ

JED PC543: a new single board computer using the AMD ELAN SC300

Effectively a 386, 33 Mhz computer with up to 4 Mb DRAM and 8 Mb. FLASH. This PC/104 is an ideal embedded controller where multiple serial ports are needed: this board features
FIVE serial ports! As well, it has a full-featured bi-directional parallel port, a RTC, a JBUS port with 20 I/O lines from a 5202 or
5204 Xilinx gate array (add your own I/O logic).
For development or code update purposes, there is a floppy disk interface on board connected to the LPT port connector...just plug in a drive and download.

There is also an SPI interface to MMC of NexFlash plug-in serial FLASH cards...ideal for data logging data storage.

This card has a standard 16-bit PC/104 expansion connector, so it can work with PC/104 flat-panel VGA display adapters, or
Ethernet network cards.
If the complexity and resolution of a full VGA card is not needed, the SC300 ELAN chip can directly drive several smaller LCD displays: CGA or 1/4 VGA mono sizes are covered.

This is a low power fully PC compatible with all you need for communications intensive applications.
Example application: On a truck with a GPS satellite location system into one port, a GSM, radio modem or differential GPS receiver into another, a remote LCD display on the dashboard via a third, a data acquisition system gathering truck engine data into another, and a serial DataSafe connected to a fifth.

PC564, a new PC/104 quad 550 UART serial interface board.

This includes a powerful decoder and interrupt control EPLD with a variety of interrupt sharing schemes selected with a DIP switch.
One channel on the base PC564 can also communicate via RS485 (2 wire).

The PC564 can also host up to three J995P opto-isolated automatic RS485 interfaces. These mount on the PC564 (still inside the PC/104 profile) and provide two-wire or four-wire connections on a plug-in Phoenix 5-pin connector. Each J995P has its own PIC microprocessor to control the TX-ON of the RS485 transmitter, allowing this card to automatically sense the start of a transmitted character without the host having to know the exact time data transmission starts and data then clears the UART's shift register. This is the same as the JED J995X (above). (Status: in prototype test.)
