It delivers 7,000+ CoreMarks® at ≤3 W typical system power and targets fanless networked edge devices such as IoT gateways and industrial routers.
For engineers reviewing the LS1021AXN7MQB datasheet, LS1021AXN7MQB pinout, LS1021AXN7MQB application, or LS1021AXN7MQB equivalent, key selection criteria include dual Cortex-A7 core support with virtualization, integrated security engine (SEC 5.5), four CAN interfaces, IEEE 1588-capable triple Gigabit Ethernet, and LCD controller for HMI-enabled embedded systems.
Technical Context
The LS1021AXN7MQB implements a cache-coherent interconnect (CCI-400) linking two ARM Cortex-A7 cores, each with 32 KB I/D cache, NEON SIMD, and dual-precision FPU. L2 cache is shared (512 KB), ECC-protected, and coherently managed.
