Microcontroller
PIC16F877A is one of the PICMicro Family microcontroller which
is popular at this moment, start from beginner until all
professionals. Because very easy using PIC16F877A and use FLASH
memory technology so that can be write-erase until thousand
times. The superiority this Risc Microcontroller compared to
with other microcontroller 8-bit especially at a speed of and
his code compression. PIC16F877A have 40 pin by 33 path of I/O. PIC16F877A
perfectly fits many uses, from automotive industries and
controlling home appliances to industrial instruments, remote
sensors, electrical door locks and safety devices. It is also
ideal for smart cards as well as for battery supplied devices
because of its low consumption. EEPROM memory makes it easier to
apply microcontrollers to devices where permanent storage of
various parameters is needed (codes for transmitters, motor
speed, receiver frequencies, etc.). Low cost, low consumption,
easy handling and flexibility make PIC16F877A applicable even in
areas where microcontrollers had not previously been considered
(example: timer functions, interface replacement in larger
systems, coprocessor applications, etc.). In System
Programmability of this chip (along with using only two pins in
data transfer) makes possible the flexibility of a product,
after assembling and testing have been completed. This
capability can be used to create assembly-line production, to
store calibration data available only after final testing, or it
can be used to improve programs on finished products.
