LS1023ASE7QQB

Microprocessors Overview

The NXP LS1023ASE7QQB is a dual-core, 64-bit ARM Cortex-A53 microprocessor from the QorIQ Layerscape LS1023A series. It operates at a maximum clock frequency of 1 GHz and utilizes an FCPBGA-621 package with dimensions of 21x21 mm. The device features 32 KB instruction and data L1 caches per core, alongside a shared 1 MB L2 cache protected by ECC. It supports DDR3L/DDR4 SDRAM memory interfaces and includes integrated security engines. The processor is qualified under AEC-Q100 standards for automotive applications and functions within a temperature range of 0°C to +105°C.

Microprocessors Procurement Notes

Verify the specific suffix 'QQB' against official NXP documentation to confirm exact binning, packaging, and qualification parameters. Ensure compatibility with existing PCB layouts due to the 21x21mm FCPBGA-621 footprint. Confirm that the 0 to 105°C operating temperature range meets the environmental requirements of the target deployment scenario before finalizing procurement.

Microprocessors Selection Notes

Select this component for designs requiring a balance of processing power and low power consumption in small-form-factor networks. The dual-core configuration offers a cost-effective alternative to quad-core variants while maintaining software compatibility with the broader Layerscape family. Consider the single-clock design and BOM optimizations when evaluating total system costs for industrial or networking infrastructure projects.

Microprocessors Part Context

This part belongs to the QorIQ Layerscape LS1023A series, designed as a purpose-built solution for small-form-factor networking and industrial applications. It shares architectural similarities with the quad-core LS1043A but provides a dual-core option for value-tier performance. The series emphasizes pin-compatibility across different core counts to facilitate scalable product development strategies.

Microprocessors Replacement Considerations

The LS1023A series is pin-compatible with the LS1043A, LS1046A, and LS1088A processors. Designers may consider these alternatives if higher core counts or different core architectures are required without changing the physical board layout.
