Renesas: MCU using advanced 28nm Embedded Flash technology

Renesas announced the sample shipment of the industry's first on-chip flash memory microcontroller using a 28 nm process technology. To contribute to the realization of next-generation green cars and autonomous vehicles with higher efficiency and higher reliability, the revolutionary RH850/E2x Series MCU incorporates up to six 400 MHz CPU cores, which makes it the first on-chip flash memory automotive MCU to achieve the industry's highest processing performance of 9600 MIPS. The new MCU series also features a built-in flash memory of up to 16 MB as well as enhanced security functions and functional safety.

Targeting ASIL-D, the highest level of the ISO 26262 functional safety standard for automotive E/E systems, the RH850/E2x Series adopts the dual core lock step CPU structure that guarantees that the calculations performed by two CPU cores are identical. The RH850/E2x also provides up to four sets of CPU pairs, and features a variety of hardware functional safety improvements. In applications where a system malfunction could lead to life-endangering accidents, these features immediately detect faults should a malfunction occur and allow system safety to be maintained. Renesas will provide safety analysis tools that can flexibly support a wide range of use cases to implement safe systems.

Under Renesas autonomy, an open, innovative and trusted platform for assisted and automated driving, Renesas provides end-to-end solutions that advance the evolution of vehicles towards next-generation green cars, connected cars, and autonomous-driving vehicles. The 28nm-generation automotive control MCU is a new breakthrough product featuring next-generation technology for achieving vehicle control, which, together with the R-Car Family of systems-on-chip designed for cloud connectivity and sensing, constitute the two main pillars of the Renesas autonomy Platform.

Samples of both 28nm and 40nm MCUs from RH850/E2x are scheduled to be available from March 2018.
