new 32-bit All Flash(R) microcontrollers (MCUs) with built-in Ethernet
interface and embedded flash memory. The new products are ideal for
remote and supervisory control of industrial devices and
building-management systems and include six 128-pin variants, named
V850ES/JH3-E and three 144-pin variants, named V850ES/JJ3-E.
The new products have the following features: (1) Integrated Ethernet
media access controller (MAC) channel, eliminating the need for an
external Ethernet controller; (2) Up to 512 kilobytes (KB) of flash
memory and up to 124 KB of random access memory (RAM), making it
possible to run network software using on-chip memory alone; (3)
Peripheral functions including full speed USB 2.0 interface and CAN
interface.
Originally deployed as a networking technology for office computers,
servers, and office automation equipments, Ethernet is now the world's
most widespread wired local area network (LAN) technology. Over the
next few years, Ethernet is expected to be further used for remote and
supervisory control of industrial devices, building-management
systems, home networks, and utility meters for the gas, water, and
electricity. Factory Automation equipments in particular has been a
field in which designers traditionally used proprietary network
architectures but with the growing popularity of Ethernet, more and
more developers are moving to Ethernet to facilitate network
communication.
