MCP750-1342 Technical Specifications

Name: MCP750-1342 MOTOROLA Card AND PLC control module
Price: 6578 CNY
Availability: InStock

Overview

The MCP750-1342 is a family of PowerPC microprocessor-based CompactPCI host-slot processor modules. Leveraging Motorola’s PowerPlus Architecture, it delivers unprecedented levels of performance and functionality.

Equipped with Motorola’s low-power, high-performance PowerPC 750 microprocessor (with 1MB secondary cache), the module integrates a PCI bus for on-board peripherals, a processor/memory bus-to-PCI bus bridge, and a 64-bit bridge to the CompactPCI interface. It packs optimal performance and functionality into a single CompactPCI slot, maximizing the capabilities of Motorola’s low-power, high-performance microprocessor.

TMCP700 Transition Module

The TMCP700 transition module provides industry-standard connector access to the following interfaces:

IEEE-1284 parallel port
Single mouse/keyboard connector
Two USB Series A receptacles
EIDE and floppy connectors
Two RJ-45 connectors (for asynchronous serial ports configured as EIA DTE)
