The other 32 are in four register banks, RB0 –RB3 of Learn about the 8051 Microcontroller, its architecture, features, and programming techniques for embedded systems.

What is a Microcontroller? Microcontroller is a programmable digital processor with necessary peripherals. Both microcontrollers and microprocessors are complex sequential digital circuits meant to carry out job according to the program / instructions. Sometimes analog input/output interface makes a part of microcontroller circuit of mixed mode (both analog and digital nature).

8051 MCU Architecture Irrespective of the manufacturer, the internal hardware design i.e. the 8051 Microcontroller Architecture remains more or less the same. The following image shows the 8051 Microcontroller Architecture in a block diagram style. Tutorial on Instruction Set types of 8051 Microcontroller, Addressing and PCON contains general user Modes, Instructions Types, Data Transfer, Arithmetic, Logical, Boolean. The 8051 is a flexible microcontroller with a relatively large number of modes of operations. Your program may inspect and/or change the operating mode of the 8051 by manipulating the values of the 8051’s Special Function Registers (SFRs).

Quick Links Account Products Tools & Software Support Cases Manage Your Account Profile Settings Notifications Various assembler directives in 8051 microcontrollers are used during assembly language programming. Unlike instructions being compiled and written to chip program memory, directives are commands of assembly language itself and have no influence on the operation of the microcontroller. Some of them are obligatory part of every program while some are used

Although the PSW register is 8-bit wide, only 6 bits are used by the 8051 microcontroller. The other two bits are user-definable and can be used according to the needs of the programmer.

Where are the Special Function Registers located? If you are familiar with the architecture of the 8051 microcontroller, you might remember that it has 128 bytes of RAM. Well, that only 6 bits with is not entirely true. The 8051 microcontroller has 256 bytes of RAM divided into two parts; a 128-byte general-purpose area and a 128-byte special function register space.
