LS1046ASE8Q1A

Microprocessors Overview

The LS1046ASE8Q1A is a microprocessor featuring four 32-bit/64-bit Arm Cortex-A72 cores operating up to 1.6 GHz, with a shared 2 MB L2 cache and 32 KB L1 data/48 KB L1 instruction caches per core. It includes one DDR4 SDRAM controller supporting ECC, eight SerDes lanes for high-speed interfaces including three PCIe 3.0 controllers, one SATA 3.0 controller, and multiple Ethernet options. The device integrates Data Path Acceleration Architecture (DPAA) with Frame Manager, Queue Manager, Buffer Manager, and Security Engine. It operates within a temperature range of 0°C to 105°C and utilizes a 780-ball FC-PBGA package measuring 23 mm x 23 mm.

Microprocessors Procurement Notes

Verify the specific suffix Q1A against official NXP documentation to confirm the exact operational temperature range and security fuse settings. Ensure compatibility with required DDR4 memory configurations and validate that the 780 FC-PBGA package dimensions align with the target PCB layout constraints before finalizing procurement.

Microprocessors Selection Notes

Select this component when a balance of multicore processing power and dedicated hardware acceleration for networking tasks is required. Consider the pin compatibility with other Layerscape processors like the LS1023A or LS1043A if future scalability is a design goal. Evaluate thermal management requirements given the 0°C to 105°C operating range and the density of the 780-ball BGA package.

Microprocessors Part Context

The LS1046A belongs to the NXP Layerscape family, designed for communications applications requiring high performance and low power consumption. It shares architectural similarities with the LS1026A but offers double the core count. The processor is part of the EdgeVerse platform, emphasizing secure boot and hardware-accelerated virtualization capabilities suitable for modern embedded network infrastructure.
