Big guy, what are KEIL C51 and KEIL MDK?
Let me popularize this for you.
Big guy


KEIL is the name of the company, and sometimes it also refers to all software development tools from KEIL. In 2005, Keil was acquired by ARM and became one of ARM’s companies.
KEIL C51, also known as PK51, is a development tool for microcontrollers based on the 8051 core, developed by KEIL and supports most 8051 cores, based on the uVision IDE.
The 51 microcontroller we refer to is the one that uses the 8051 core. Therefore, to learn the 51 microcontroller, you need to install KEIL C51.


MDK (Microcontroller Development Kit), also known as MDK-ARM, KEIL MDK, RealView MDK, KEIL For ARM, all refer to the same thing. ARM now uniformly uses the name MDK-ARM. The MDK device database contains many manufacturers’ chips and is a tool specifically designed for microcontroller development, created to meet the needs of engineers developing embedded software based on MCUs. It supports ARM7, ARM9, Cortex-M4/M3/M1, Cortex-R0/R3/R4, and other ARM microcontroller cores.
The STM32 we will learn later is a microcontroller with the ARM Cortex-M3 core, so students who need to learn about the 32 series should install MDK.


Alright, that’s the introduction for now, you should know the situation. Finally, here are the installation packages and the installation cracking video for MDK and C51. Everyone with a computer should hurry to install it!
