Embedded firmware programming is different from normal PC programming because it is usually designed to do one task or set of tasks. The power of a PC is that it can run many different programs. You may choose to write a letter in Word or read a pdf document in reader,

There is a whole segment of electronic devices that don’t need this flexibility. In fact mobility and size may be a primary consideration that tips the balance in favor of a microcontroller. Consider a microwave which needs to read the keypad and display the resulting cook time. After the cook time is set and the start button is pressed, it will need to count down the seconds and turn the microwave off after it is complete. Pretty simple, right? Firmware has some definite advantages in this case. The microcontroller is simpler and therefore cheaper than a comparable microprocessor. Also the fact that the program is simpler makes it more reliable. What would you do if your microwave blue screened while making popcorn?

Firmware is normally referred to as "embedded" because it is stored in memory internal to the chip. In fact,

A contract firmware firm such as ours helps a customer select the best microcontroller for the job and then provides the underlying embedded firmware programming required to run the task. A contract firmware company can typically complete a design in less than 6 months and possibly sooner depending upon the complexity of the project. Using contract firmware labor means you pay for the design and maintenance tasks if you choose which means you don’t have to hire a full time embedded firmware programmer.
