XE8000
Encyclopedia
The XE8000 series is a low-power microcontroller
family from XEMICS (now a business unit of Semtech
). Advanced analog features are combined with a proprietary RISC CPU
named CoolRISC on all XE8000 devices. The CPU has 8-bits data bus and 22 bits instruction bus. All instructions (including 8*8 bit multiplication) are executed in 1 clock cycle. The analog features include the ZoomingADC a new type of SD
ADC that includes capabilities to amplify and offset the input signal during the acquisition.

Central processing unit
The central processing unit is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in...

Timer
A timer is a specialized type of clock. A timer can be used to control the sequence of an event or process. Whereas a stopwatch counts upwards from zero for measuring elapsed time, a timer counts down from a specified time interval, like an hourglass.Timers can be mechanical, electromechanical,...
