1.1 Product Overview
LH75400/01/10/11 is a family of four 16/32-bit System-on-Chip (SoC) devices:
• LH75401 — contains the superset of features. See Chapter 2.
• LH75411 — similar to the LH75401, without the Controller Area Network (CAN) 2.0B
interface. See Chapter 3.
• LH75400 — similar to the LH75401, but with a Grayscale Liquid Crystal Display (LCD)
Controller only. See Chapter 4.
• LH75410 — similar to the LH75400, without the CAN 2.0B interface. See Chapter 5.
All four devices are low-cost solutions that use the ARM7TDMI-S core integrated with a
wide variety of functions. All operate up to 51.6096 MHz at 3.3 V and come in a 144-pin
Low-profile Quad Flat Pack (LQFP) package.
NOTE: In this User's Guide, the nonspecific term 'SoC' or 'device' refers collectively to all four SoCs.
