Hardware RTOS speeds industrial Ethernet chip
Renesas has announced a series of industrial Ethernet communication chips with support for multiple communication protocols.
“Because the hardware covers heavy load operations for the CPU, the combination of the CPU and integrated hardware RTOS result in responsiveness five to ten times that of a conventional software real-time OS,” claimed the firm. “In addition, the fluctuation caused by inconsistencies in the operation time with conventional CPU processing is reduced substantially from one-fifth to one-tenth of the previous level.”
Protocols such as CC-Link IE and EtherCAT are supported, as well as the automotive CAN (control area network) protocol which has been adopted so enthusiastically by industrial users – and conventional UART.
“There are also plans to provide support for the SSCNET III/H optical network standard, which uses fully synchronous communication,” said Renesas.
R-IN32M3-CL is the variant with a slave controller for supporting 1Gbit/s CC-Link IE Field as a circuit.
The -EC variant has a slave for EtherCAT with a 10/100Mbit/s EtherPHY.Tags: ethernet, hardware RTOS, industrial, Renesas
