Cost-efficient, small footprint ARM9 microprocessor

Digi Device Cloud
  • 32-bit system-on-chip with ARM926EJ-S core
  • Integrated 10/100 Mbit Ethernet MAC
  • On-chip high-performance encryption engine
  • Power management and rich set of interfaces
  • Drop-in replacement option for NS7520 designs

Part of Digi’s NET+ARM processor family, the NS9210 is the ideal choice for every network-enabled embedded application requiring a cost-efficient 32-bit solution. With high-performance attributes such as up to 150 MHz clock speed and 4 KB of I-cache and D-cache, it is the ideal choice for a broad range of applications such as security/access control, medical, industrial/building automation, transportation and remote monitoring.

Offering a subset of essential interfaces provided on the NS9215, the NS9210 supports industrial operating temperature and integrates two independent on-chip DRPIC1655X processor cores for a growing list of application-specific interface implementations. State-of-the-art data privacy and superior performance is guaranteed by an integrated and NIST-certified 256-bit AES accelerator. Digi's patented dynamic power management addresses the needs of power budget conscious designs.

The easy-to-use and complete NS9210 development kit for NET+OS® is based on the field-proven ThreadX® Real-Time Operating System, and delivers a true and IPv6-ready turnkey solution. It includes the Eclipse-based Digi ESP™ IDE as well as all integrated building blocks for secure network-enabled embedded software development.

The NS9210 is also a pin-compatible upgrade path for existing NS7520 designs requiring minimized design migration effort.
