Introduction
The PCM-53E52 is a compact Half-EBX board with PC/104Plus, SSD, Ethernet, and four COM ports.
Unlike other compact Half-EBX boards, the PCM-53E52 has an optional Analog and Digital I/O Daughter
Board, allowing for data acquisition and greater flexibility.
The PCM-53E52 features a low power AMD® ELAN-SC520 133Mhz processor (no fan required, P120
equiv.). This compact Half-EBX board has on board, 16MB of SDRAM memory standard. A 32MB to
128MB memory upgrade option is also available as is a DiskOnChip® 2000 (DOC) solid state flash disk
(no moving parts). The PCM-53E52 can be connected onto a network using the Realtek® RTL8139C
10/100Base-T Ethernet controller and onboard RJ-45 connector. In addition, the PC/104Plus connectors
provide both ISA and PCI connectivity.
The PCM-53E52 offers three RS-232 serial ports, one RS-232/422/485 serial port, and a parallel port that
supports SPP/EPP/ECP parallel modes. This board includes a mini-DIN keyboard/mouse connector, an
onboard 34-pin FDD interface that supports two floppy disk drives, and an onboard 44-pin EIDE interface
that supports two EIDE devices. The PCM-53E52 is 5.75" in length and 4" wide, making it a great fit for
harsh environment and limited-space applications.
The optional Analog and Digital I/O Daughter Board adds micro-controller capability with the power of a
PC. The I/O daughter board includes 16, General Purpose I/O lines and eight high current sink outputs on
a standard I/O Rack compatible 50 pin header. This board also includes: 16 channels of A/D with 10
or12-bit resolution, and four channels of D/A with 12-bit resolution. In addition, the I/O daughter board
supports up to a 24-key keypad and is capable of driving up to a 40 x 4 character and graphic LCD
displays.
