Digi International’s NS7520 is a 32-bit system-on-chip (SoC) ASIC designed for use in intelligent networked devices and internet appliances. This processor is based on the standard architecture in the Net+Arm family of devices. The NS7520 can support most any networking scenario and includes a 10/100BaseT Ethernet MAC and two independent serial ports (each of which can run in UART or SPI mode). The CPU is an ARM7TDMI 32-bit RISC processor core with a rich complement of support peripherals and memory controllers for various types of memory (including Flash, SDRAM, EEPROM, and others), programmable timers, a 13-channel DMA controller, an external bus expansion module, and 16 general-purpose input/output (GPIO) pins.

The NS9360 is a single chip 0.13μm CMOS network-attached processor. The CPU is the ARM926EJ-S core with MMU, DSP extensions, Jazelle Java accelerator, and 8 kB of instruction cache and 4 kB of data cache in a Harvard architecture. The NS9360 runs up to 177 MHz, with an 88 MHz system and memory bus, and 44 MHz peripheral bus. The NS9360 operates at a 1.5 V core and 3.3 V I/O ring voltages. The NS9360 is designed specifically for use in high performance intelligent networked devices and Internet appliances including high performance/low-latency remote I/O, intelligent networked information displays, and streaming and surveillance cameras. The NS9360 is a member of the award-winning Net+Arm family of SoC solutions for embedded systems. Product unit costs are reduced dramatically with complete SoC, including Ethernet, display support, a robust peripheral set, and the processing headroom to meet the most demanding applications.
