The world’s smallest 8pin microcontrollers, from Microchip, now have devices with advanced analogue to digital features. The PIC12C671 and PIC12C672 8bit, one time programmable microcontrollers, enable intelligent features to be integrated into mechanical designs. Advanced analogue features include A/D converter and two analogue channels for measuring environmental conditions such as temperature, pressure, motion and voltage. Specific applications include intruder detectors, pressure gauges, water meters, smoke detectors, thermostats, rheostats, and battery chargers. The Pic12C671 and 12C672 have 1024 and 2048 words of program memory respectively and 128bytes of user RAM.
