Tuesday, 20 October, 2009 | Supplied by: Soanar Limited


NEC Electronics has developed nine 32-bit All Flash microcontrollers with built-in ethernet interface and embedded flash memory.

The devices are suitable 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 devices have: integrated ethernet media access controller channel, eliminating the need for an external ethernet controller; high-performance CPU core - the V850ES/Jx3 family can execute 103 Dhrystone million instructions per second at a clock speed of 50 MHz; up to 512 KB of flash memory and up to 124 KB of random access memory, making it possible to run network software using on-chip memory alone; peripheral functions including full-speed USB 2.0 interface and CAN interface; network software includes an optimised ethernet driver and a lightweight transmission control protocol/internet protocol stack.
