Product Overview
The MPC855TVR50D4 is a 32-bit PowerQUICC communications processor from NXP’s MPC8xx family, operating at 50 MHz. Its independent CPM co-processor handles low-level network protocol tasks to reduce main core load, equipped with integrated 10/100Mbps Fast Ethernet MAC, SCC/SMC serial ports and PCMCIA interface. Packaged in lead-free PBGA-357 (25mm×25mm), it delivers low-latency data transmission for network gateways, industrial controllers and legacy telecommunication equipment.
Core Advantages
Dual-Processor Network Architecture
Utilizes an autonomous RISC-based Communications Processor Module (CPM) that processes data link protocol operations and low-level interrupts independently of the central core, optimizing data throughput and minimizing application lag.
Integrated 10/100 Fast Ethernet MAC
Natively incorporates a dedicated Ethernet controller link on-chip, simplifying board-level routing layouts and minimizing the necessity for complex external localized LAN acceleration silicon chips.
Flexible Multi-Protocol Interface Ports
Equipped with highly flexible Serial Communications Controllers (SCCs) capable of parsing various telecommunication serial data lines—including HDLC, UART, Transparent, and Asynchronous Time-Division Multiplexed (TDM) channels.
Comprehensive On-Chip System Protection
Features embedded system logic utilities including watchdog timers, periodic interrupt timers, and a robust external bus clock manager to guarantee stable, deterministic execution inside hazardous or unmonitored factory spaces.

Frequently Asked Questions
Q1: Is your currently available stock of the MPC855TVR50D4 100% original and genuine?
A: Yes, we guarantee that all MPC855TVR50D4 microprocessors in our inventory are 100% brand-new, factory-original products directly from NXP Semiconductors / Freescale. Every component batch is fully verified through our rigorous intake audit protocols and is stored and shipped in secure anti-static tray containers to safeguard BGA solder ball co-planarity.
Q2: What is the main design advantage of the dual-processor layout (Core CPU + CPM) inside the MPC855 family?
A: The dual-core architecture prevents networking bottlenecks. While the main 32-bit core processes upper-tier application software and operational workflows, the independent Communications Processor Module (CPM) handles low-level frame packing, bit-level error validation, and high-frequency data line traffic. This distribution of tasks eliminates CPU thread locking during heavy network loads.
Q3: What specific detail does the “VR” designator represent in this NXP part number sequence?
A: Under the PowerQUICC part numbering convention, the “VR” code indicates that this device is encapsulated within a lead-free (Pb-free) Plastic Ball Grid Array (PBGA) packaging format. This enables total compliance with modern global green electronics manufacturing directives, including RoHS and REACH regulations.
Q4: How can our design department request official reference manuals, hardware layouts, or secure a volume wholesale quotation?
A: Please input your target volume numbers and technical specifications into the Quick Inquiry form found directly on this webpage. Our embedded processing engineering group will analyze your requirements and follow up with comprehensive data assets and custom pricing within 24 hours.
