Ethernet and USB On-the-Go peripherals, coupled with compact size, are the key features of two 68K/ColdFire families from Freescale Semiconductors. Though the chips are designed for applications like industrial control, home automation and environmental monitoring that require small size and low pricing, they still have 256 Kbytes of Flash. The two, 32-bit families run at 60 and 80 MHz, delivering 2.1 MIPS. One version offers a USB 2.0 full-speed Host/Device/On-The-Go Controller, while the other provides a10/100 Fast Ethernet Controller with Ethernet PHY. In volume quantities, the 3.3V lines list for $5.49 and $7.99.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
