In the first instalment of a three-part article we will look at recent developments in 32-bit ARM based microcontrollers, concentrating on those devices that are available, do not cost an arm and a leg or require a major investment in surface mount soldering equipment!
ARM stands for Advanced RISC Machine, where RISC means Reduced Instruction Set Computer. The ARM 32-bit architecture has been around for a number of years and has been used in products where low power consumption is essential such as for mobile phones and PDA’s. Its 32-bit core is available in several guises including the ARM7, ARM9, ARM10 and the recently announced ARM11, each of which offers enhanced levels of computing power.
