Basic Features of 68HC11 Family of Microcontrollers
The 68HC11 (also abbreviated as 6811 or HC11) is an 8-bit microcontroller that was introduced by Motorola in the year 1984. The production of these chips was later done by Freescale semiconductor. Currently they are fabricated by NXP semiconductors which acquired Freescale semiconductor. I have listed some of the basic features of 68HC11 family of…

How a Microcontroller can be used in a Temperature Measurement System
The figure below illustrates the key elements of a temperature measurement system employing a MC68HC11 microcontroller. The temperature sensor provides a voltage proportional to the temperature; an example of such a sensor is LM25 (a temperature sensor that can be used with an analogue to digital converter like ADC0804 to give a digital output suitable…
