The UNC20 module is housed in an industry-standard DIL48 package, making it extremely easy and cost-effective to integrate into designs which require Ethernet connectivity.Typical applications include industrial automation systems, medical instrumentation, retail point-of-sale scanners, data acquisition systems. The modular approach offers significant advantages compared to full custom designs since the interface to the module remains the same even if any device on the module changes.This results in a number of benefits to the OEM:- easier adaptation to application's performance (speed, memory size)- better long-term availability- shielding of complex board technology from the user (fine pitch/multi-layer/BGA)- cost-effective solutions for low to medium volume projects.The Microcontroller NET+ARM NS7520NetSilicon's NET+ARM is a cost-effective, highly integrated, 32-bit, system-on-a-chip ASIC, designed for use in intelligent networked devices and Internet appliances.To support a variety of networking scenarios, the NET+ARM includes a 10/100 Ethernet. MAC with MII interface and two independent serial ports, each of which can run in UART, HDLC or SPI mode. The CPU is an ARM7TDMI 32-bit RISC processor with a rich complement of support peripherals and memory controllers for various types of memory (including flash, SDRAM, EEPROM, and others), programmable timers, two 13-channel DMA controllers , an external bus expansion module, and up to 16 general-purpose I/O pins.
