MPC8321ZQADDC

Overview

The MPC8321ZQADDC is a microprocessor belonging to the PowerQUICC II Pro family, manufactured by NXP Semiconductors (formerly Freescale). It features a single-core e300c2 processor with a 32-bit data bus width and a maximum clock frequency of 266 MHz. The device utilizes a PBGA-516 package measuring 27 x 27 mm with a 1 mm pitch and 2.25 mm height. It includes 16 kB L1 instruction cache and 16 kB L1 data cache. Operating voltage is 1 V, with I/O voltages supporting 1.8 V, 2.5 V, and 3.3 V. The component supports DDR1/DDR2 SDRAM memory types and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an e300c2 core without floating-point unit for efficient integer operations
• Includes QUICC Engine for hardware-accelerated network protocol processing
• Features SEC2.2 hardware security engine for cryptographic acceleration
• Supports multiple interface protocols including Ethernet, USB 2.0, and PCI

Applications

• Residential gateways
• SOHO network devices
• VPN routers
• Industrial control systems

Procurement Notes

Verify the specific suffix ZQADDC against official NXP documentation to confirm pinout compatibility and feature set. Ensure RoHS compliance status matches project requirements, as older Freescale batches may differ. Confirm moisture sensitivity level handling procedures during assembly. Validate that the leaded packaging meets environmental regulations for the target market.

Selection Notes

Select this component when a cost-effective communications processor with integrated security and networking engines is required. The absence of a floating-point unit makes it suitable for integer-heavy tasks. Consider the 266 MHz performance limit and PBGA-516 package constraints for PCB layout. Verify thermal management capabilities for the specified operating temperature range.

Part Context

This part belongs to the MPC8321E/MPC8323E PowerQUICC II Pro family. These processors are designed for small office/home office (SOHO) and residential gateway applications. They offer higher CPU performance and faster interfaces compared to previous PowerQUICC II generations while maintaining low power consumption and reduced board space requirements.
