RH850/D1M

High-end automotive microcontroller suitable for instrument cluster supporting basic or low-level 2D drawing.

 

The RH850/D1M microcontroller has up to 5 MB embedded flash, 3.5 MB embedded RAM and dedicated features for instrument clusters with middle or high level 2D drawing. Therefore it integrates a 2D GPU, Sprite Engine, JPEG Unit, HUD Warping Engine and the RAM Wrapper. Furthermore it supports an external memory interface up to DDR2.
