'''R-Car M2''' is a mid-range performance embedded [[tri-core]] SoC designed by [[Renesas]] for the automotive industry and introduced in late 2013. The M2 incorporates two {{armh|Cortex-A15}} cores operating at 1.5 GHz and a third {{renesas|SH-4A}} core for real-time processing. This chip incorporates [[imagination technologies|Imagination]]'s {{imgtec|PowerVR SGX544}} [[GPU]] operating at 520 MHz and supports up to dual-channel DDR3-1600 memory.
