Trusted FLASH MCU
Renesas takes optimum EMI/EMS
performance into account in its
MCU design. Our careful attention
at this stage drastically reduces the
cost of EMI/EMS countermeasures.
This function offers complete
protection of a specified domain in
the built-in MCU flash memory.
This prevents illegal copying of the
software IP incorporated in the
protected domain.
Note: We plan to develop Trusted FLASH as a
standard function in the Renesas F-ZTAT MCUs.
Renesas MCUs realize process advances at the same time
as achieving reductions in power consumption. Low power
consumption design is made easy.
