LS1021ASN7KQB

LS1021ASN7KQB is NXP’s LS1021A QorIQ System-on-Chip (SoC). It’s designed for secure networking and industrial edge devices such as routers, gateways, and switches.
Key points:
- Dual ARM Cortex-A7 cores for efficient performance at low power.
- Hardware security/crypto engine to accelerate TLS, encryption, and authentication.
- Integrated high-speed I/O options (e.g., PCIe, USB, Ethernet interfaces) and memory controller for DDR3/DDR4.
- Targeted for embedded Linux (Yocto) and other Linux-based deployments.
- The suffix N7KQB denotes a specific package/revision of the device.
In short, LS1021ASN7KQB is a compact, security-focused SoC for small-to-medium network appliances, combining dual-core processing, crypto hardware, and rich peripherals. For exact specs (clock speeds, exact I/O counts, memory options), consult the official LS1021A datasheet and the package guide.
