Product Brief
OVERVIEW
The
ECONA
CNS21XX integrates a high performance ARM CPU Core with a rich feature set delivering a highly flexible, scalable and
comprehensive SoC solution for network-based connected multimedia devices. This highly optimized SoC provides an ideal platform for
low-cost, low-power, high-performance retail and home network connected devices. The CNS21XX family provides developers with an
easy-to-use development environment with Linux operating system support, pre-ported applications and drivers for multimedia peripherals.
