Of RISC architectures, such as a large register set and separate memory spaces for program instructions and data. It is an example of a CISC computer, but also has some of the features The 1980s and early 1990s, and compatible derivatives remain popular up to today. Intel's original versions were very popular in ) who was an American engineer specializing in microprocessors and he did an amazing job. The MCS-51 family succeeds the MCS-48 family, if you take a closer look at both you will see the resemblance. I also have a Facebook Group on Retro Computing and Electronics, feel frtee to join! About the MCS-51 processor family On this page I give an overview of the MCS-51 family MCU’s and the different types. I alsoĬollect old processors so I have a love of MCS-51 types of chips in my collection, not only from Intel but also from a lot of other manufacturers. I even build an 8052 programming IDE for Windows 10 / 11. Nowadays I still used the STC and Atmel 8752 in a lot of electronic projects. I even made a Basic version once but at the time modems needed much more processing power, we switched to Intel 80188 processors. All of our low end modems had the 8052 as MCU I really loved this processor, I started with an 8031Īnd external eprom but soon we switched to Atmel series of 8052 chips with internal flash memory. At a certain point I knew the processor in and out and every trick it had. Many years ago (1987) I was programming the 8052 professionally and I had all the assemblers and a PL/M compiler and an in circuit emulator at myĭevelopment seat.
