MPC8545VTATGB

Overview

The MPC8545VTATGB is a 32-bit embedded microprocessor from the PowerQUICC III family, built on the e500 core architecture. It operates at clock speeds up to 1 GHz and features a dual-issue, superscalar pipeline with a seven-stage depth. The device integrates 32 KB each of L1 data and instruction caches, along with 256 KB of on-chip L2 cache. Connectivity includes two Tri-Speed Ethernet Controllers (TSEC) supporting 10/100/1000 Mbps, a RapidIO controller, and PCI-X/PCI bus interfaces. Memory support is provided via a DDR SDRAM controller with ECC capability.

Feature Summary

• Integrates high-performance e500 compatible embedded cores for balanced processing throughput
• Provides extensive I/O connectivity including Gigabit Ethernet and RapidIO interfaces
• Includes hardware security engines and enhanced debugging support mechanisms

Applications

• Enterprise networking equipment
• Telecom transmission and switching systems
• Industrial control applications

Procurement Notes

Verify the specific suffix VTATGB against official NXP documentation to confirm package type and temperature range. Confirm current lifecycle status as many devices in this series are marked obsolete or end-of-life. Ensure compatibility with existing board designs regarding voltage levels and pin assignments before procurement.

Selection Notes

Select this component when gigahertz-class performance is required alongside integrated high-speed serial and parallel interfaces. The e500 core offers software compatibility with other Power Architecture processors. Consider the 783-pin BGA package constraints and thermal requirements during system design.

Part Context

This processor belongs to the PowerQUICC III family developed by Freescale Semiconductor, now part of NXP Semiconductors. These devices utilize a scalable System-on-Chip platform designed for communications processing. The MPC8545 variant specifically targets applications requiring robust integration of network controllers and processing power within a single die.

Replacement Considerations

Consult official substitution guides for equivalents such as the MPC8540 or MPC8548E families. Verify functional parity and pin compatibility before replacing obsolete units.
