The 8051 microcontroller high number of microcontroller providers incorporate touch-sensing capabilities in their designs. Portable electronics such as cell phones, media players and gaming devices are examples of microcontroller-based touch screens.

Bit as well as byte addressable RAM area of 16 bytes. Four 8-bit ports, short models have two 8-bit ports.

Typical applications[ edit ] chips the 8051 microcontroller used in a wide variety of control systems, telecom applications, robotics as well as in the automotive industry.

Pin should be held high for 2 machine cycles.

The has a built-in oscillator amplifier hence we need to only connect a crystal at these pins to provide clock pulses to the circuit. PIN 40 and Pins 40 and 20 are The 8051 microcontroller and ground respectively. As described in the the 8051 microcontroller of thethis chip contains a built-in flash memory.

PIN 30 is called ALE address latch enablewhich is used when multiple memory chips are connected to the controller and only one of them needs to be selected.

What is 8051 Microcontroller?

the 8051 microcontroller We will deal with this in depth in the later chapters. This is "program store enable". Set when addition produces a signed overflow. Register select 0, RS0. The 8051 microcontroller low-order bit of the register bank. Set when banks at 0x08 or 0x18 are in use.

Register select 1, RS1. The high-order bit of the register bank.

Set when banks at 0x10 or 0x18 are in use. Auxiliary the 8051 microcontrollerAC. Set when addition produces a carry from bit 3 to bit 4.

Carry bitC. Often used as the general register for bit computations, or the "Boolean accumulator". Accumulator, A 0xE0 This register is used by most the 8051 microcontroller.

B, register 0xF0 This is used as an extension to the 8051 microcontroller accumulator for multiply and divide instructions. The 8051 microcontroller bit of these bytes may be directly accessed by a variety of logical operations and conditional branches.

For the former, the most significant bit of the accumulator can be addressed directly, as it is a bit-addressable SFR.
