Embedded computing systems are based on hardware components that can control the operation of the systems. Microcontrollers are a special type of digital processor that can be found in a wide range of appliances, from electronic devices like sensors, commercial products, home appliances, industrial systems body monitoring systems, embedded systems means any type of computer system that is embedded into a larger system directly or indirectly. One of such microcontrollers is ATtiny85-20SFR.

ATtiny85-20SFR is a low-cost, low-power 8-bit AVR microcontroller and it includes 8K program memory, 512 bytes of EEPROM, 512 bytes of SRAM, up to 6 I/O lines, 3 timers and a 10-bit ADC. It has an on-chip debugging system that allows debugging of application code without the need of external debug hardware. It has an operating voltage range from 1.8V to 5.5V, so it can operate in both low-power applications and high-performance applications. The ATtiny85-20SFR is available in a 20-lead TSSOP package and it can be used in a wide variety of applications.

ATtiny85-20SFR applications include sensor node monitoring systems, dataloggers, remote monitoring systems, security systems, medical devices, metering systems and wearable applications. It is also used in automotive, industrial and commercial applications. Its low power consumption makes it suitable for battery-powered applications. Its on-chip debugging system and the ability to program and debug over USB makes it suitable for developing and debugging a variety of applications. The ATtiny85-20SFR also supports development tools like AVR Studio and Atmel Studio, which allows developers to easily create, debug and program applications.

ATtiny85-20SFR works by executing instructions from a program stored in the internal memory of the microcontroller. It fetches a set of instructions from memory and executes them one by one. The instructions can be conditional or unconditional. Conditional instructions are executed only if a given condition arises otherwise, the instruction is skipped. After an instruction is executed, the processor increments the program counter which points to the next instruction. The processor also contains a number of internal registers and flags which are used to store the results of instructions and to indicate the current state of the processor.

ATtiny85-20SFR also supports a number of peripherals such as timers, counters, I/O interfaces, communication modules and analog-to-digital converters. The on-chip peripherals provide functions like input/output, communication, timing, analog/digital conversion, and computation. These peripherals help to interface the microcontroller with external hardware components. In addition, it supports a number of software libraries and tools which allows the user to easily create applications for the microcontroller.

In conclusion, ATtiny85-20SFR is a low-cost, low-power 8-bit AVR microcontroller that can be used in a wide variety of embedded system applications. It has an on-chip debugging system, a wide operating voltage range and a number of peripherals that makes it suitable for a range of applications. In addition, its low power consumption makes it an ideal choice for battery-powered applications. With the help of development tools and libraries, developers can create and debug applications for this microcontroller with ease.
