MPC8321CVRADDCA

Overview

The MPC8321CVRADDCA is a PowerQUICC II Pro integrated communications processor built on the e300c2 core. It features a 32-bit architecture with 16 KB L1 instruction and data caches, dual integer units, and an on-chip MMU. The device includes a QUICC Engine block with five unified communication controllers (UCCs) supporting Ethernet, HDLC, UART, and TDM protocols. It integrates a 32-bit PCI controller, USB 2.0 interface, and a DDR1/DDR2 SDRAM memory controller. Operating at up to 266 MHz, it supports I/O voltages of 1.8 V, 2.5 V, and 3.3 V within a PBGA-516 package.

Feature Summary

• Integrates a high-performance e300c2 core with dual integer units for efficient parallel processing.
• Features a versatile QUICC Engine block with five UCCs for flexible protocol termination including Ethernet and ATM.
• Includes hardware security acceleration for cryptographic algorithms via the SEC 2.2 engine.
• Supports multiple peripheral interfaces such as PCI, USB 2.0, and local bus for system connectivity.

Applications

• ADSL SOHO and residential gateways
• Modem/routers
• Industrial control systems
• Test and measurement applications

Procurement Notes

Verify component authenticity through official NXP channels or authorized distributors. Confirm the specific ordering suffix matches the required voltage and temperature specifications. Check for end-of-life status as this family may be discontinued. Ensure design compatibility with existing software drivers and hardware schematics before procurement.

Selection Notes

Select this processor for applications requiring a balance of CPU performance and dedicated networking capabilities. Consider the e300c2 core's lack of a floating-point unit when evaluating computational needs. Verify that the available UCCs meet the specific protocol requirements, noting that ATM support may vary by variant. Ensure the PBGA-516 package fits the board layout constraints.

Part Context

This component belongs to the MPC8323E PowerQUICC II Pro family, designed as a cost-effective solution for networking applications. It extends previous PowerQUICC offerings with improved CPU performance and faster interfaces. The family targets small office/home office and broadband access markets, offering flexibility for evolving protocol standards.

Replacement Considerations

Check for direct substitutes within the MPC8321E or MPC8323E families. Verify pinout and feature compatibility, particularly regarding UTOPIA support which differs between variants. Consult the latest product summary page for updated availability and errata information.
