NS7520 Data Sheet
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.
