LS1046ASE8Q1A

Microprocessors Overview

The LS1046ASE8Q1A is a microprocessor from NXP Semiconductors featuring four 32-bit/64-bit Arm Cortex-A72 cores operating up to 1.6 GHz. It utilizes a 780 FC-PBGA package measuring 23 mm x 23 mm and supports an operating temperature range of 0°C to +105°C. The device includes a single 2 MB L2 cache, 32 KB L1 data cache, and 48 KB L1 instruction cache per core. It integrates a DDR4 SDRAM memory controller with ECC support running up to 2.1 GT/s, alongside Data Path Acceleration Architecture (DPAA) for packet processing.

Microprocessors Feature Summary

• Integrates four Arm Cortex-A72 cores sharing a 2 MB L2 cache for high-performance computing
• Includes Data Path Acceleration Architecture (DPAA) with hardware acceleration for cryptography and queue management
• Features eight SerDes lanes supporting multiple high-speed interfaces including PCIe 3.0 and Ethernet
• Provides integrated security engine and secure boot capabilities for trusted system initialization

Microprocessors Applications

• Enterprise routers and switches
• Network attached storage (NAS)
• Security appliances and gateways
• Virtual customer premise equipment (vCPE)

Microprocessors Procurement Notes

Verify the specific ordering suffix against official documentation to confirm exact performance grades, temperature ranges, and security configurations. Ensure compatibility with required DDR4 memory modules and external power sequencing components. Confirm that the FC-PBGA package dimensions align with the target PCB layout and thermal design specifications before finalizing procurement.

Microprocessors Selection Notes

Select this component when a balance of multi-core processing power and dedicated network acceleration is required. The integrated DPAA offloads packet parsing and classification tasks from the CPU cores. Consider the 780-ball BGA package size and pin density during board design. Evaluate the need for specific interface combinations such as SATA or USB 3.0 based on application requirements.

Microprocessors Part Context

This processor belongs to the QorIQ LS1046A family within the Layerscape architecture. It is designed for embedded networking applications requiring high throughput and low latency. The chip integrates networking elements, accelerators, and basic peripherals into a single system-on-chip solution, reducing bill of materials compared to discrete component designs.
