DESCRIPTION
The LH75401 is a low cost microcontroller that utilizes the
ARM7TDMI-S core integrated with a wide variety of functions
including the ability to control STN, color STN, TFT, HR-TFT, and
Adavanced-TFT displays with up to 4,096 colors. Other functions
include: 32KB of on-chip SRAM, three UARTs, SSP, CAN version
2.0b, three 16-bit Counter/Timers, Analog to Digital Converter with
integrated touch screen controller, Watchdog Timer, and Low Volt-
age Detector. The LH75401 operates up to 90 MHz at 3.3 V over the
industrial temperature range of -40°C to +85°C and is offered in
a 144-pin LQFP package.
