'''R-Car M1A''' is a mid-range performance embedded [[dual-core]] SoC for the automotive industry designed by [[Renesas]] and introduced in 2011. The M1A features a single {{armh|Cortex-A9|l=arch}} core and an additional {{renesas|SH-4A|l=arch}} core, both operating at 800 MHz. This chip incorporates [[Imagination]]'s {{imgtec|PowerVR SGX540}} [[GPU]] operating at 200 MHz. This SoC supports up to 1 GiB of dual-channel DDR3-1066 memory.

Introduced early-2011 with samples available in May 2011. Renesas expected mass production to begin in June 2012.
