MPC8309CVMAFDCA

Overview

The MPC8309CVMAFDCA is a PowerQUICC II Pro integrated communications processor featuring an e300c3 core operating at 266 MHz. It includes 16 KB L1 instruction and data caches, a QUICC Engine block with five Unified Communication Controllers (UCCs), and a 32-bit PCI controller. The device supports DDR2 SDRAM via a 16/32-bit memory controller with ECC. Key interfaces include USB 2.0, FlexCAN, I2C, SPI, DUART, and Ethernet MII/RMII. It operates on a 1.0 V core supply and 3.3 V I/O voltage within a MAPBGA-489 package.

Feature Summary

• Integrates a high-performance e300c3 superscalar processor core with floating-point capabilities and dynamic power management.
• Features a QUICC Engine block with five UCCs for flexible protocol support including Ethernet, HDLC, and TDM.
• Includes an enhanced local bus controller supporting boot from parallel NOR/NAND Flash and multiple chip selects.
• Provides integrated security features and DMA engines for efficient data movement and processing offload.

Applications

• Residential gateways
• Modem/routers
• Industrial control systems
• Test and measurement applications

Procurement Notes

Verify the specific suffix 'FDCA' against official NXP documentation to confirm temperature range and packaging details. Confirm current production status as older MPC8309 variants may be obsolete. Ensure compatibility with existing board designs regarding pinout and voltage levels before procurement.

Selection Notes

Select this component for applications requiring high integration of communication protocols and networking functions. Consider the e300c3 core performance and QUICC Engine flexibility for protocol offloading. Evaluate DDR2 memory interface requirements and available GPIO pins for system design constraints.

Part Context

The MPC8309 belongs to the PowerQUICC II Pro family, designed for cost-effective, highly integrated communications processing. It extends previous offerings with higher CPU performance and faster interfaces. The device targets networking applications needing low-cost solutions with rapid time-to-market.

Replacement Considerations

Consult NXP documentation for recommended replacements if the MPC8309 series is discontinued. Verify functional and pin compatibility with successor devices in the PowerQUICC or Power Architecture families.
