MPC8309CVMAHFCA

Overview

The MPC8309 is a PowerQUICC II Pro integrated communications processor featuring an e300c3 core with 16 KB instruction and data caches. It operates at frequencies up to 417 MHz with a 1.0 V core supply voltage. The device includes five Unified Communication Controllers (UCCs), a DDR2 memory controller supporting up to 333 MHz, and a 32-bit PCI interface running at 66 MHz. Additional peripherals include USB 2.0, FlexCAN, eSDHC, and dual I2C interfaces.

Feature Summary

• Integrated QUICC Engine block with five Unified Communication Controllers for flexible protocol support including Ethernet, HDLC, and TDM.
• Enhanced local bus controller supporting boot from parallel NOR and NAND Flash with programmable clock ratios.
• Dual-role USB 2.0 controller supporting high-speed host, device, and OTG operations.
• DDR2 SDRAM memory controller with integrated ECC and support for up to two physical banks.

Applications

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

Procurement Notes

Verify the specific suffix of the part number against official NXP documentation to confirm temperature range and package variations. Confirm current product status as some MPC8309 variants may be obsolete or end-of-life. Ensure compatibility with required DDR2 and PCI interface specifications during design-in.

Selection Notes

Select this processor for applications requiring high integration of communication protocols and networking features. Consider the e300c3 core performance and available peripheral sets such as UCCs and DMA engines. Evaluate power consumption requirements against the specified operating conditions and thermal characteristics.

Part Context

The MPC8309 belongs to the PowerQUICC II Pro family, designed for cost-effective and highly integrated communications processing. It extends previous offerings by adding higher CPU performance and faster interfaces while addressing time-to-market and power consumption constraints in embedded networking solutions.

Replacement Considerations

Consult official NXP documentation for confirmed substitute part numbers within the MPC83xx family. Verify pinout and electrical compatibility before considering alternatives.
