Microchip’s new PIC16(L)F170X and PIC16(L)F171X family of 8-bit microcontrollers (MCUs) combine a rich set of intelligent analog 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 analog control loops, sensor amplification and basic signal conditioning. 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 are designed to handle tasks with no code or supervision from the CPU to maintain operation.
The CLC peripheral allows designers to create custom logic and interconnections specific to their application. The COG peripheral is a powerful waveform generator that can generate complementary waveforms with fine control of key parameters, such as phase, deadband, blanking, emergency shutdown states and error recovery strategies.
The NCO is a programmable precision linear frequency generator, ranging from <1 Hz to 500 kHz+. It offers a step up in performance, while simplifying designs requiring precise linear frequency control, such as lighting control, tone generators, radio tuning circuitry and fluorescent ballasts.
The new MCUs feature up to 28 KB of self-read/write Flash program memory, up to 2 KB of RAM, a 10-bit ADC, a 5-/8-bit DAC, capture-compare PWM modules, standalone 10-bit PWM modules and high-speed comparators (60 ns typical response), in addition to EUSART, I²C and SPI peripherals. They also feature XLP technology for typical active and sleep currents of just 35 μA/MHz and 30 nA, respectively.
