B4420NXN7QQMD

Microprocessors Overview

The B4420NXN7QQMD is a QorIQ Qonverge System on Chip (SoC) microprocessor manufactured by NXP Semiconductors. It features a quad-core architecture comprising two Starcore SC3900FP DSP cores operating at 1.2 GHz and two e6500 CPU cores running at 1.6 GHz. The device utilizes a 64-bit data bus and is housed in a 1020-ball FCPBGA package. Memory hierarchy includes 32 kB instruction and 32 kB data L1 caches per core, alongside 2 MB of L2 cache for both instruction and data storage. It supports multiple I/O voltages including 1V, 1.2V, 1.35V, 1.5V, and 1.8V, with an operational temperature range from 0°C to +105°C.

Microprocessors Procurement Notes

Verify the specific suffix QQMD against official NXP documentation to confirm pinout and thermal specifications. Ensure compliance with export regulations as this product may require additional documentation for shipment from the United States. Confirm moisture sensitivity level and shelf life requirements prior to assembly to prevent package damage during soldering processes.

Microprocessors Selection Notes

Select this component when a mixed-signal environment requiring both general-purpose computing and specialized digital signal processing is necessary. The inclusion of the MAPLE-B3 accelerator makes it suitable for applications demanding high throughput in packet processing or cryptographic operations without burdening the main CPU cores.

Microprocessors Part Context

This processor belongs to the NXP QorIQ Qonverge family, designed to bridge the gap between traditional networking processors and application processors. It targets markets requiring flexible compute resources that can handle complex operating systems while simultaneously managing real-time signal processing tasks efficiently.

Microprocessors Replacement Considerations

Consult NXP official substitution lists for verified alternatives. Generic cross-references are not recommended due to specific architectural differences in the Qonverge series.
