Preliminary Data Sheet
DESCRIPTION
The SHARP BlueStreak LH75400/01/10/11 family
consists of four low-cost 16/32-bit System-on-Chip
(SoC) devices.
LH75401 — contains the superset of features.
LH75411 — similar to LH75401, without CAN 2.0B.
LH75400 — similar to LH75401, but with a Gray-
scale LCDC only.
LH75410 — similar to LH75400, without CAN 2.0B.
