P4040NSN7PNC

Microprocessors Overview

The P4040NSN7PNC is a microprocessor from the NXP QorIQ P4 series, featuring four Power Architecture e500mc cores operating at frequencies up to 1.5 GHz. It utilizes a 32-bit data bus and includes a three-level cache hierarchy with 32 KB instruction and data L1 caches per core, 128 KB private L2 cache per core, and a shared L3 cache. The device supports DDR2 and DDR3 memory controllers and integrates multiple high-speed interfaces including Ethernet, PCIe, USB, I2C, SPI, and UART. It operates within a temperature range of 0°C to +105°C and is housed in a 1295-FCPBGA package.

Microprocessors Procurement Notes

Verify component authenticity and datasheet revisions before integration. Confirm that the specific suffix matches design requirements as variations exist within the family. Check for end-of-life status or obsolescence notices from NXP Semiconductors. Ensure supply chain stability due to potential discontinuation risks associated with older architecture families.

Microprocessors Selection Notes

Select this processor for applications requiring high-throughput networking and control plane processing. Evaluate thermal management solutions suitable for the FCBGA package and 105°C operating limit. Compare against newer QorIQ T-series or LS-series alternatives if new designs are permitted. Verify peripheral compatibility with existing system buses and memory configurations.

Microprocessors Part Context

This component belongs to the QorIQ P4 multicore communications processor family, which also includes models like P4080 and P4081. These processors were designed for high-performance networking using 45 nm technology. The P4040 specifically offers a four-core configuration compared to the eight-core P4080, targeting cost-sensitive yet high-performance embedded networking markets.

Microprocessors Replacement Considerations

NXP recommends transitioning to Power Architecture T4080 or Arm-based LS1046, LS2044, and LS2080 processors for new designs. Direct pin-compatible replacements are not available; architectural migration is required.
