Microcontroller is a compact electronic device that integrates a central processing unit (cpu), memory (both ram and rom), input/output (i/o) ports, and various peripherals onto a single integrated circuit (ic chip) for specified tasks.In this comprehensive course, you'll delve into the fundamentals of the 8051 microcontroller, a cornerstone in embedded systems.
In this video architecture, features and various versions of 8051 microcontroller are explainedfor the theory of 8051 and pic microcontroller refer the follo.If the program size is more than 4 k bytes 8051 will fetch the code automatically from external memory.A microcontroller can also be referred as a 'microcomputer'.
Operating voltage range of 2.4v to 6v.Let us now discuss the architecture of 8051 microcontroller.
From understanding its architecture to mastering programming in both assembly and embedded.The oscillator circuit is responsible for generating a square wave signal of a specific frequency.These versions are 8051h, 8051bh and 8051ch.

O'Ward Overcomes Palou To Win Indy 200 In Ohio
TROYES, France -- Frenchman Anthony Turgis emerged victorious from a long breakaway through the dust of gravel roads to claim the ninth stage of the Tour de France after a hectic day of racing, marked by relentless attacks Sunday.
Behind the breakaway, race leader Tadej Pogacar tried to set the race on fire as the fight between the main contenders raged but could not gain time on his main rivals for the yellow jersey.
Turgis, who rides for the Total Energies team, posted the biggest win of his career in a sprint, edging Tom Pidcock and Derek Gee in the Champagne city of Troyes. It was the third stage win by a French rider since the race started last week.
"It's incredible, it was a long time since I did not win," said Turgis. "It was a long day, the team put its trust in me by giving me carte blanche today. I dedicate this win to all the people who trusted me."
There was no major change in the overall standings, with Pogacar keeping his 33-second lead over Remco Evenepoel. Two-time defending champion Jonas Vingegaard remained in third place, 1:15 off the pace.
The tough stage took riders on a nearly 200-kilometer (124-mile) trek through 14 sections of so-called white roads -- including six in the stage finale -- that have become a trademark of Italy's Strade Bianche.
Pogacar loves riding on this difficult terrain, having won the Strade Bianche twice, and proved it with a series of sharp attacks that put his rivals on the back foot. Primoz Roglic suffered but managed to bridge gaps every time he got dropped and kept his fourth place overall, 1:36 behind Pogacar.
Vingegaard adopted a conservative strategy and did not collaborate with Pogacar and Evenepoel when they had the possibility to break away from other top contenders.
"For sure I will remember," Pogacar said. "But everybody have their own race, I have nothing against it. I like to race with the heart and that was one of those days."
Asked whether he thought Vingegaard and his team were afraid of him, Pogacar replied: "I think they are scared of me and they just follow me."
Evenepoel was also critical of Vingegaard's strategy.
"It's a bit of a shame that Jonas did not take turns with us, because otherwise the race would have been over, we could have taken three or four minutes," Evenepoel said.
The peloton will enjoy its first rest day on Monday.
The Tour paid tribute to Norwegian rider Andre Drege, who died Saturday after crashing in a downhill at the Tour of Austria. To honor his memory, cyclists from the Norwegian team Uno-X Mobility arrived at the start line five minutes ahead of the start, with the rest of the peloton staying behind during a moment of applause.
There was a flurry of attacks from the start. A group of 10 riders including Turgis managed to escape before the first sector of gravel and were joined by a handful of counterattackers.
Behind, a traffic jam of riders formed at the foot of a very steep segment of white roads, with many competitors forced to dismount and to run up the climb. Vingegaard and Pogacar avoided the jam but Roglic got dropped, lagging about 30 seconds behind at one point before he bridged the gap.
Vingegaard later suffered a mechanical problem and teammate Jan Tratnik gave his leader his bike. Pogacar then sped up the pace, followed by Evenepoel. The pair could not break away from the pack, though, and Vingegaard's Visma Lease A Bike teammates moved to the front to add to the frenetic pace.
The battle between the main contenders intensified when Evenepoel attacked with 78 kilometers left in the Côte de Chacenay. Pogacar and Vingegaard did not panic and managed to chase him down. Roglic, however, could not follow. Still on his teammate's bike, Vingegaard did not take his turn in the lead as the trio joined the main break.
With Vingegaard refusing to collaborate, they finally slowed down and Evenepoel looked dejected by his rival's attitude.
"It's their tactics, there is nothing we can do," Evenepoel added.
Pogacar attacked again with about 20 kilometers left as Evenepoel and Roglic could not follow. Vingegaard, with the help of teammate Matteo Jorgenson, stayed in his wake. Again, Vingeaard did not take his turn and Pogacar stopped his effort.
Pogacar tried to go away one last time with eight kilometers left, but once again Vingegaard responded.
