AT89C5

1

is an 8-bit microcontroller and belongs to Atmel’s

8

0

5

family. ATMEL 89C5

1

has

4

KB of Flash programmable and erasable read only memory (PEROM) and

1

2

8

bytes of RAM. It can be erased and program to a maximum of

1

0

0

0

times. In

4

0

pin AT89C5

1

, there are four ports designated as P

1

, P

2

, P3 and P

0

. All these ports are 8-bit bi-directional ports, i.e., they can be used as both input and output ports. Except P

0

which needs external pull-ups, rest of the ports have internal pull-ups. When

1

s are written to these port pins, they are pulled high by the internal pull-ups and can be used as inputs. These ports are also bit addressable and so their bits can also be accessed individually. Port P

0

and P

2

are also used to provide low byte and high byte addresses, respectively, when connected to an external memory. Port 3 has multiplexed pins for special functions like serial communication, hardware interrupts, timer inputs and read/write operation from external memory. AT89C5

1

has an inbuilt UART for serial communication. It can be programmed to operate at different baud rates. Including two timers & hardware interrupts, it has a total of six interrupts.
