1. Meeting the computer needs of the task efficiently & cost effectively-
· Speed , the amount of the ROM & RAM, the no. of the i/o ports & timers, size, packaging, power consumption.
· Easy to upgrade.
2. Availability of software develop tool-
· Assembler. Debugger(use in check syntax), Compiler, emulator(hard wire).
Wide availability & reliable source of microcontroller
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
89c51 is an microcontroller of 8051 series it is an 8-bit device packed in 40-pin package.
AT89C51 function
The at89c52 are ones that are more advanced. This means that they are programmable compared to the 8051 which is not. So this makes a really big difference.
In a traffic light control application, a microcontroller is used to manage the timing and sequence of the traffic lights at an intersection. It processes input from sensors or timers to determine when to change the lights, ensuring safe and efficient traffic flow. The microcontroller executes programmed logic to switch the lights from red to green to yellow, while also coordinating pedestrian signals if needed. By implementing these functions, the microcontroller enhances road safety and optimizes traffic management.

The most important factor in choosing a microcontroller for a battery-based embedded product is power consumption. A microcontroller with low power consumption extends battery life, which is crucial for portable devices. Additionally, it's essential to consider the processing capabilities, peripheral support, and sleep modes, as these features can significantly impact overall energy efficiency and performance in the product's intended application. Balancing these factors ensures optimal functionality while maximizing battery longevity.

the criteria in choosing our national hero are the following: * must be a Filipino citizen * displayed unconditional love for the country * done something good or for the benefit of the country * must be loyal and a patriot
That depends on the specific microcontroller.
