8-bit PICs gain integrated peripherals for reduced system cost

March 31, 2014 // By Graham Prophet
Microchip’s PIC16(L)F170X and PIC16(L)F171X family of 8-bit microcontrollers (MCUs) combine intelligent analogue and core-independent peripherals, along with cost-effective pricing and eXtreme Low Power (XLP) technology.

Available in 14-, 20-, 28-, and 40/44-pin packages, the 11-member PIC16F170X/171X family of MCUs integrates two op amps to drive analogue control loops, sensor amplification and basic signal conditioning, while reducing system cost and board space. These new devices also offer built-in Zero Cross Detect (ZCD) to simplify TRIAC control and minimise the EMI caused by switching transients. These are the first PIC16 MCUs with Peripheral Pin Select, a pin-mapping feature that gives you the flexibility to designate the pinout of many peripheral functions. The PIC16F170X/171X are general-purpose MCUs that are ideal for a broad range of applications, such as consumer (home appliances, power tools, electric shavers), portable medical (blood-pressure meters, blood-glucose meters, pedometers), LED lighting, battery charging, power supplies and motor control.
