Overview
The NET+50 is a low-cost, high-performance 32-bit network attached ARM7 processor
developed especially for print servers. It includes an RM7TDMI microprocessor core,
integrated 10/100Base-T Ethernet MAC with an MII interface, a 10-channel DMA
controller and a memory controller supporting all of the popular memory devices in use
today.
Like all of our processors, the NET+50 is supported by the royalty-free NET+Works
®
software development tool suite. The integrated NET+Works package contains either
Green Hills
