Sharp Blue Treak LH75400 User Manual

7/3/03 xxxiPrefaceThis User’s Guide describes the SHARP BlueStreak LH75400/01/10/11 16/32-bit ARM-based System-on-Chip (SoC) devices. These four devices are:• LH75400• LH75401• LH75410• LH75411.This User’s Guide is the principal technical reference for these SoCs. It is intended forengineers responsible for designing, integrating, programming, and testing embeddedsystems based on these four SHARP SoCs. Electrical Characteristics are found in theData Sheet.This User’s Guide assumes that the reader:• Is familiar with the basic principles and techniques of embedded-microprocessorsystem engineering• Has familiarity with programming the ARM7TDMI-S Processor• Has access to documentation, support, and training available from ARM.NOTE: This User’s Guide does not cover the ARM instruction set. For information about ARM instruction set,and programming the ARM7TDMI-S processor, visit the ARM Web site at www.arm.com.Supplemental DocumentationAn abridged version of this User’s Guide (and containing the Electrical Characteristics), isavailable as a Data Sheet. An even more abbreviated version is available as a single-pageProduct Brief. Please contact your local SHARP representative for details, or visit theSHARP Microelectronics of the Americas Web site at www.sharpsma.com.Terms and ConventionsThis User’s Guide describes four devices that differ only in feature sets. In referring tothese devices collectively, the term ‘LH75400/01/10/11’ becomes clumsy and difficult toread, so this Guide uses the terms ‘SoC’ and ‘device’ to describe this set of System-on-Chip devices.For information about specific terms and acronyms, see the Glossary in this User’s Guide.Multiplexed PinsThese devices are manufactured in a 144-pin Low Profile Quad Flat Pack (LQFP) pack-age. Some pins have only one function, but others are multiplexed and may carry as manyas three functions. Although more than one function can be assigned to multiplexed pins,the pins support only one function at a time.
