The Digi NS7520 is a high-performance, highly integrated, 32-bit system-on-a chip ASIC designed for use in intelligent networked devices and Internet appliances. The NS7520 is based on the standard architecture in the NET+ARM family of devices.The NS7520 can support most any networking scenario, and includes a 10/100 BaseT 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.NET+ARM is the hardware foundation for the NET+Works family of integrated hardware and software solutions for device networking. These comprehensive platforms include drivers, popular operating systems, networking software, development tools, APIs, and complete development boards.

技术参数

  • CPU core Integrated 10/100 Ethernet MAC ARM7TDMI 32-bit RISC processor 32-bit internal bus
  • Integrated 10/100 Ethernet MAC 10/100 Mbps MII-based PHY interface 10 Mbps ENDEC interface TP-PMD and fiber-PMD device support
