Main features:
- PIC® Microcontrollers with 16-bit PWM and communications for precision drive capability in a small footprint
- Lowest cost PIC microcontroller with EUSART, advanced PWM and core independent peripherals
- Combines a Complementary Waveform Generator (CWG) and powerful analog peripherals
- Offers low power technology for battery powered applications
Microchip announces, from Embedded World, an expansion to its portfolio of 8-bit PIC® microcontrollers with the PIC12(L)F157X family, incorporating multiple 16-bit PWMs and a suite of analog peripherals and serial communications in an 8-pin package. . These microcontrollers provide three full 16-bit PWM, with independent timers for applications where high resolution is required, such as LED lighting, stepper motors, battery charging, and other general applications. In addition to standard and center-aligned PWM output modes, the peripheral also has four compare modes and can serve as an additional 16-bit timer.
The CWG, along with 16-bit PWM, can be used to create full-bridge and half-bridge drive control. The CWG is a powerful waveform generator that can generate complementary waveforms with precise control of key parameters such as polarity, deadband, and emergency shutdown states. It provides an economical solution that saves board space and component cost when driving FETs in motor control and power conversion applications. The 16-bit CWG and PWM are Core Independent Peripherals (CIPs) combined with the 10-bit A/D converters, comparator, and 5-bit D/A analog peripherals to allow feedback and closed-loop control. .
The PIC12F157X microcontrollers are well suited for a wide variety of applications, such as indoor/outdoor LED lighting and RGB LED color mixing; consumer applications such as electric shavers and radio controlled toys; and LED lighting inside the car.
The PIC12F1572 allows communication with a EUSART for the lowest price in the PIC microcontroller catalogue. The incorporation of the EUSART allows a serial communication of general application and LIN for the automobile and industrial control. Integrated 10-bit A/D converters enable touch/human interface applications using Microchip's mTouch™ capacitive sensing solution. In addition, the PIC12F157X offers non-volatile data storage with HEF (High Endurance Flash) memory. The “LF” versions incorporate low power technology for active currents below 35 µA/MHz and sleep mode currents as low as 20 nA, which is ideal for battery-powered applications.
Microchip's full suite of development tools support the PIC12F157X microcontrollers, including the MPLAB® X Integrated Development Environment (IDE); and the PICkit™ 3 (PG164130) which is priced at $44,95; Low Pin Count 8-Bit Development Kit (DM164130-9) for $25,99; the MPLAB ICD 3 (DV164035) for $189,99; and the PICDEM™ Lab Development Kit (DM163045) for $134,99. Microchip has also created the RGB Board Development Platform and “LED Color Mixing” Application Note (#AN1562) to help developers design lighting applications using the PIC12F157X family.
