Motorola PCE I 01-W3839F-07A Processor Module

General Description

The 01-W3839F-07A is part of Motorola's PCE I series of VMEbus processor modules, built for embedded computing applications requiring deterministic performance. This single-board computer (SBC) utilizes a PowerPC architecture, providing a balance of processing power and low power consumption. It is designed to operate as a system controller in VMEbus chassis or as a standalone embedded processor in industrial environments.

Key Features

• Processor: PowerPC 740 or 750 (G3) running at 300-400 MHz, with 256 KB L2 cache.

• Memory: 128 MB SDRAM (expandable to 512 MB), 32 MB Flash for boot firmware and application storage.

• VMEbus Interface: VME64 compliant, system controller capability, A32/A24 addressing, D32/D16/D08 data transfers.

• I/O Interfaces: 2x Ethernet (10/100 Base-T), 2x RS232 serial ports, 1x parallel port, 2x USB 1.1.

• PMC Expansion: Single PMC slot (PCI Mezzanine Card) for adding custom I/O or communication modules.

• Real-Time Clock: Battery-backed with calendar.

• Watchdog Timer: Programmable hardware watchdog for system recovery.

• Operating Systems: Supports VxWorks, Linux, QNX, and other real-time operating systems.

Technical Specifications

• Power Consumption: < 20 W typical.

• Operating Temperature: 0°C to +55°C (extended temperature options available).

• Storage Temperature: -40°C to +85°C.

• Humidity: 5% to 95% non-condensing.

• Form Factor: 6U VMEbus, single-slot (4HP width).

• Dimensions: 233 x 160 mm (6U x 160mm depth).

• Compliance: VME64 specification ANSI/VITA 1-1994.

Functional Description

The 01-W3839F-07A integrates a PCI-to-VME bridge for high-speed data transfer between the processor and VMEbus. Boot firmware (U-Boot) supports loading of operating systems from Flash, network, or IDE storage. The module includes DMA engines for efficient data movement. It also features a programmable interrupt controller for handling VMEbus interrupts. Diagnostic LEDs on the front panel indicate power, status, and user-defined conditions.

Applications

• Industrial automation and robotics control.

• Data acquisition and signal processing systems.

• Military and aerospace embedded computing.

• Medical imaging and diagnostic equipment.

• Telecommunications infrastructure.

Integration and Software

The module is designed for use in standard VMEbus chassis with P1/P2 backplanes. Board support packages (BSPs) are available for VxWorks, Linux, and QNX. Development tools include GNU toolchains and integrated development environments. The PMC slot allows expansion with additional Ethernet, serial, or data acquisition modules.

Certifications

• CE, FCC Class A.

• RoHS compliant.

• Designed to meet industrial shock and vibration standards.
