The Digi Net+ARM series is a family of 32-bit microcontrollers designed for network-enabled embedded systems. These System-on-Chip (SoC) solutions are ideal for high-bandwidth applications in intelligent network devices and Internet appliances. The Net+ARM microcontrollers, such as the NS7520 and NS9360, provide a robust platform for developing secure and network-connected products.
Key features of the Net+ARM microcontrollers include built-in Ethernet connectivity, UART, DMA, SPI interfaces, and support for multiple memory types, making them suitable for various industrial and consumer applications. They are often paired with Digi’s NET+OS, a development environment that simplifies building networked devices by providing an integrated solution that includes networking, security services, and a real-time operating system (ThreadX).
NET+ARM products are commonly used in devices requiring reliable, secure connectivity, and their development environment includes rich networking protocols (e.g., IPv4/IPv6), security features (e.g., SSL/TLS, IPsec), and file system support, making them highly versatile for applications such as industrial control, automation, and IoT
Digi Net+ARM® Microcontrollers
Digi’s Net+ARM® microcontrollers are system-on-chip (SoC) processors designed for intelligent networked devices and internet appliances. Built on the standard architecture of the Net+ARM family, these processors are ideal for a wide range of networking scenarios. They feature a 10/100BaseT Ethernet MAC, two independent serial ports (configurable in UART or SPI mode), and a powerful RISC processor core. The SoC also includes a robust set of peripherals, memory controllers (supporting Flash, SDRAM, and EEPROM), programmable timers, a 13-channel DMA controller, an external bus expansion module, and 16 GPIO pins.
One example, the NS9360, is a single-chip network-attached processor built on a 0.13 µm CMOS process. It features an ARM926EJ-S core with an MMU, DSP extensions, a Jazelle Java accelerator, 8 kB of instruction cache, and 4 kB of data cache in a Harvard architecture. Running at up to 177 MHz, with an 88 MHz system/memory bus and a 44 MHz peripheral bus, the NS9360 operates at 1.5 V for the core and 3.3 V for I/O. Designed for high-performance networked devices, this processor excels in applications like remote I/O, intelligent displays, and streaming cameras. As part of Digi’s award-winning Net+ARM family, it delivers a complete SoC solution, reducing unit costs while providing extensive peripheral support and processing power for demanding embedded systems
