Overview
The NXP USA Inc. LS1024ASN7JLA is a member of the LS1024A family of multicore communications processors. These processors are based on single- or dual-core Arm® Cortex®-A9 CPU cores and are designed to deliver scalability, superior packet handling capabilities, and vastly increased VPN and SSL throughput. The LS1024A is optimized for low power consumption, typically less than 3 W at 900 MHz, making it suitable for a variety of network-centric applications. Although the LS1024A is not recommended for new designs (with the LS1023A being the suggested alternative), it remains a powerful solution for existing implementations.
