1 Introduction
This manual describes the operation, configuration and installation instructions for the PMC23X and PMC24X
High Capacity Disk modules. The PMC23X/PMC24X family provides a single PMC slot storage solution utilizing
industry standard ATA rotating and solid state disks. Designed to be plugged onto a host processor (e.g., Single
Board Computer) card, these products provide an extremely compact, flexible and economical high performance
storage solution.
The PMC23X/PMC24X family of embedded disk modules offers a totally new high performance, low cost option
for file system and boot storage. Combining high performance controllers developed for high-end workstations,
with disk technology used in laptops, the PMC23X/PMC24X embedded disk module delivers very high data rates
in a compact form factor implemented with components designed for physically demanding environments. With
the PMC23X/PMC24X “single slot,” computing solutions do not need to compromise in either capacity or
performance. In addition, card edge PCI systems can be accommodated using RAMiX's PMC239 adapter for
rapid prototype and development.
The PMC23X/PMC24X is fully PMC compliant, meeting all mechanical, electrical and protocol specifications.
Disk capacities from 10GB to 60GB (rotating media) and from 32MB to 2GB (Flash) are supported.
The PCI controller on the PMC23X/PMC24X makes full and efficient use of the PCI bandwidth. FIFO buffers
allow effective use of PCI burst modes, critical to achieving low PCI overheads. The PMC23X/PMC24X can
execute data transfers at full PCI bus speeds. The PMC23X/PMC24X will mount on any PMC location (either
directly on a processor card or on a PMC carrier board).
On the disk side, the controller can support ATA 66 for the PMC 233/234/235 and ATA 100 on the
PMC243/244/245.
1.1 Features
The PMC233 and PMC234 use the CMD Technology CMD646 controller, the PMC235 uses the CMD648
controller. The PMC243, PMC244 and PMC245 use the Promise Technology PDC20269 controller (fully PCI 2.1
compliant). The most significant difference between the two sets of products is the performance, both on the PCI
(the PMC233, PMC234 and PMC235 supports 32bit/33Mhz, the PMC243, PMC244 and PMC245 supports 32 bit
wide PCI and speeds up to 66Mhz) and on the ATA (to disk) bus.
Within each group, the products are distinguished by mechanical layout and the style of disk they support.
All of these modules comply with the CMC specification for PCI Mezzanine Cards (commonly known as PMC).
As such, they will directly connect to any Single Board Computer (SBC) or Expansion Card that supports PMC
modules. All initialization, and functional configuration of the module is done automatically by software.
All of the products offer:
• Boot OS (e.g. Windows, NT, RTOS, etc.)
• Runs under the local Operating System File System
• Utilize industry standard storage solutions (e.g., 2.5” and Compact FLASH drives), allowing capacity and
performance improvements as they become available.
• Drivers for most popular RTOS, UNIX and Microsoft Window environments

1.2.1 PMC233/PMC243
These two products offer high capacity, high performance disk solutions. They integrate a 2.5” disk (either
rotating or Solid State) directly into the product assembly. As such they provide a small form factor rugged
storage solution for embedded systems.

Features include:
• Boot and Runtime file system solution in a single slot
• Rotating Media from 10GB to 60GB
• Flash disk from 32MB to 2GB
• Flash option available in Industrial Temperatures
• Fast read/write performance (rotating media)
• Compact and extremely rugged
1.2.2 PMC234/PMC244
Industry standard CompactFlash/MicroDrive storage devices are accommodated either via front panel (excellent
for situations where the storage needs to be easily transportable), or recessed for higher mechanical robustness.
(NB: the PMC234/PMC244 do not have hot swap support, power must be off before removing/inserting the
drive).

2 Hardware Installation
This chapter provides unpacking, hardware preparation and installation procedures for the PMC233/PMC243
modules.
2.1 Unpacking Instructions
RAMiX’s boards are protected by an anti-static envelope and/or wrapping. Observe anti-static precautions and
work at an approved anti-static workstation when unpacking the board.
Note: The units are shipped in an individual, reusable shipping box. When the shipping
container is received, inspect it for any evidence of physical damage. If the container is
damaged, request that the carrier’s agent be present during unpacking and inspection of
the unit.
Unpack the module from shipping carton. Check and verify that all items are present by referring to the packing
list.
2.2 Included Items
Each PMC23X/PMC24X is shipped with a corresponding PMC assembly.
2.3 Handling
Electronic assemblies use devices that are sensitive to static discharge; this applies to both the
PMC23X/PMC24X and the host board onto which it will be mounted. Observe anti-static procedures when
handling these boards. The PMC23X/PMC24X should be in an anti-static plastic bag or conductive foam for
storage or shipment.

3.7 Assembly Diagram
The PMC23X/PMC24X module is now ready for installation. Turn all system power off. Remove the host board
from the chassis (if currently installed). Locate the PMC connectors on the host board. Carefully plug the
PMC23X or PMC24X into the mating connectors on the host's printed circuit board. Be sure module is seated
properly into CMC connectors on the host. Use screws to fasten module into host PCB.
1. Remove the four screws from the bottom of the stand-offs.
2. Line up the J1 and J2 connectors on the host PCB to the PMC23X/PMC24X J1 and J2 connectors.
3. Push the PMC23X/PMC24X down, making sure all connectors are positioned properly.
4. Use the four screws to connect the PMC23X/PMC24X stand-offs to the host PCB.

4 Architecture
The PMC23X/24X utilizes a single chip solution that interfaces the PCI to the ATA bus. The PMC23X is ATA66,
compatible while the PMC24X extends the compatibility to ATA100. The PMC23X has a 32/33Mhz PCI bus
interface. The PMC24X has a 32/66Mhz PCI bus interface. Further, the PCI bus signaling of the PMC23X is +5V
only, while the PMC24X is +3.3V as well as +5V.
