The new features which are aimed at safety critical applications are: Most of the new features seemed to be aimed at anything with a motor in it, either domestic appliances or small industrial products.
They also have 24 bit “Signal Measurement Timers”. For example, they have hardware zero crossing detection which could be very useful in applications such as TRIAC control or measuring mains frequency but are nothing to do with “safety critical applications”. They really seem to be targeted at specific applications because they also include new features not seen on PICs before but which are nothing to do with safety. The PIC12F1612 and the PIC16F1613 (plus LF versions of both) seem to be the only ones for now. They are also quite a bit more expensive than the PICs.Īt the moment there are very few Microchip devices in this new category for “safety critical applications”. The Texas Instruments “Hercules” TMS470M/TMS570M and RM4x microcontrollers are 16/32 bit, high pincount devices which are presumably targeting a different market to the low pincount 8 bit devices offered by Microchip.
The first thing I found out was that there don’t seem to be many microcontrollers aimed at safety critical applications. I was interested to see what the difference was and how they might compare with other manufacturers’ microcontrollers aimed at similar applications. Microchip recently announced some microcontrollers for “safety critical applications”.
