When we have to learn about a new computer we have to familiarize about the machine capability we are using, and we can do it by studying the internal hardware sign (devices architecture), and also to know about the size, number and the size of the registers.
A microelectronic is a single chip that contains the processor (the CAP]), non-volatile memory for the program (ROOM or flash), volatile memory for input and output (RAM), a clock and an 1/0 control unit. Also called a “computer on a chip,” billions of microelectronic units (Mimics) are embedded each year in a myriad of products from toys to appliances to automobiles. For example, a single vehicle can SE 70 or more microelectronics. The following picture describes a general block diagram of microelectronic.
ROTC A real-time clock (ROTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. Although the term often refers to the devices in personal computers, servers and embedded systems, Arts are present in almost any electronic device which n ROTC DISHES FEATURES: s to keep accurate time. 1 . Real-time clock (ROTC) counts seconds, minutes, hours, date of the month, month, ay of the week, and year with leap-year compensation valid up to 2100. . 56-byte, battery-backed, nonvolatile (NV) RAM for data storage. 3. Two-wire serial interface Programmable square wave output signal Automatic power-fail detect and switch circuitry. 4. Consumes less than nana in battery backup mode with oscillator running. 5. Optional industrial temperature range: -ICC to +ICC. 6. Available in 8-pin DIP or SOCIO Underwriters Laboratory (LU) recognized. BLOCK DIAGRAM REGULATED POWER SUPPLY 8 9 s
