Microchip announces the PIC16F(L)170X family of 8-bit microcontrollers (MCUs) which combine a rich set of intelligent analogue and core-independent peripherals, with cost-effective pricing and eXtreme Low Power (XLP) performance. Available in 14- and 20-pin packages, the PIC16F170X MCUs integrate two op amps to drive analogue control loops, sensor amplification and basic signal conditions, while reducing system cost and board space. These new devices are Microchip’s first PIC® MCUs with built-in Zero Cross Detect (ZCD) to simplify TRIAC control and minimise EMI caused by switching transients. In addition, the PIC16F170X MCUs are the first PIC16 devices with Peripheral Pin Select, a pin-mapping feature which gives designers the flexibility to designate the pin-out of certain peripheral functions. The PIC16F170X MCUs are ideal for general-purpose applications, as well as product segments and markets such as consumer home appliances, power tools and electric razors; portable medical equipment such as blood pressure meters, blood glucose meters and pedometers; LED lighting; battery charging; power supplies and motor-control applications.
The PIC16F170X MCU family features Core Independent Peripherals such as the Complementary Output Generator (COG) and Configurable Logic Cell (CLC). 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. In addition, the COG peripheral provides non-overlapping, complementary waveforms for such things as replacing FET drivers in motor-control applications to save cost and board space, while additionally enabling dead-band control, auto shutdown, auto reset, phase control and blanking control.
The new MCUs feature up to 14 KB of self-read/write Flash programme memory, up to 1 KB of RAM; 10-bit Analogue-to-Digital Converter (ADC); 8-bit Digital-to-Analogue Converter (DAC); Capture-Compare PWM (CCP) modules; stand-alone 10-bit PWM modules; high-speed comparators with 60 ns typical response; as well as EUSART, I2C™ and SPI peripherals. The PIC16F170X MCUs also feature XLP for typical active and sleep currents of just 35 µA/MHz and 30 nA, respectively, helping to extend battery life and reduce standby current consumption.
The PIC16F170X family is supported by Microchip’s standard suite of world-class development tools, including the PICkit™ 3 (PG164130) priced at $44.95; MPLAB ICD 3 (DV164035) priced at $189.99; PICkit™ 3 Low Pin Count Demo Board (DM164130-9) priced at $25.99; and PICDEM Lab Development Kit (DM163045) priced at $134.99.
The PIC16(L)F1703/1704/1705 MCUs are available now for sampling and production in 14-pin PDIP, TSSOP, SOIC and QFN (4 x 4 x 0.9 mm) packages. The PIC16F1707/1708/1709 MCUs are available now for sampling and production in 20-pin PDIP, SSOP, SOIC and QFN (4 x 4 x 0.9 mm) packages.
