Introduction to ARM7 LPC Microcontroller

A worldwide community of ARM partners and third-party vendors has developed among semiconductor and product design companies, including hardware engineers, system designers, and software developers. Then your first question is, how adchitecture earns?

It is the most widely used bit instruction set architecture in terms of quantity produced. There are three types of profile available.

And make embedded system by OS system programming. This is Cortex architecture which mostly used for real time purpose architetcure application abort is critical situation.

This profile is specially dedicated for microcontroller purpose only. Pin-out of LPC All these mode indicates its special work and execute under certain condition.

Modes other than User mode are collectively known as privileged modes.

Privileged modes are used to service interrupts or exceptions, or to access protected resources. ARM7 is greatest success family in embedded system application.

Low power real-time clock with independent power and dedicated 32 kHz clock input.


Vectored interrupt controller with configurable priorities and vector addresses. Up to nine edge or level sensitive external interrupt pins available.

Introduction to ARM7 Based Microcontroller (LPC2148)

Power saving modes include Idle and Power-down. CPU operating voltage range of 3. Cores designed by ARM Holdings.
