Microchip announces, from EE Live! and the Embedded Systems Conference in San Jose, the PIC16(L)F170X and PIC16(L)F171X family of 8-bit microcontrollers (MCUs), which
combines a rich set of intelligent analogue and core independent peripherals, 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, whilst 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. Additionally, these are the first PIC16 MCUs with Peripheral Pin Select, a pin-mapping feature that gives designers the flexibility to designate the pin-out 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 and electric razors; portable medical products including blood-pressure meters, blood-glucose meters and pedometers; as well as LED lighting; battery charging; power supplies and motor control.
The PIC16F170X/171X family features Core Independent Peripherals (CIP), such as the Configurable Logic Cell (CLC), Complementary Output Generator (COG) and Numerically Controlled Oscillator (NCO). These “self-sustaining” peripherals take 8-bit PIC® MCU performance to a new level, as they are designed to handle tasks with no code or supervision from the CPU to maintain operation. As a result, they simplify the implementation of complex control systems and give designers the flexibility to innovate.
The CLC peripheral allows designers to create custom logic and interconnections specific to their application, thereby reducing external components, saving code space and adding functionality. The COG peripheral is a powerful waveform generator that can generate complementary waveforms with fine control of key parameters, such as phase, dead-band, blanking, emergency shut-down states and error-recovery strategies. It provides a cost-effective solution saving both board space and component cost when, for example, driving FETs in half- and full-bridge drivers for control and power-conversion applications.
