8-bit PICs with 8 pins
2 April 2014
DSP, Micros & Memory
Microchip announced an expansion of its 8-bit PIC microcontroller (MCU) portfolio with the PIC12(L)F157X family, which features multiple 16-bit PWMs with an assortment of analog peripherals and serial communications in an 8-pin package.
These chips deliver three full-featured 16-bit PWMs with independent timers, for applications where high resolution is needed, such as LED lighting, stepper motors, battery charging and other general-purpose applications. In addition to standard and centre-aligned PWM output modes, the peripheral also has four compare modes and can serve as an additional 16-bit timer.
The Complementary Waveform Generator (CWG), in combination with the 16-bit PWMs, can be used to create half-bridge and full-bridge drive control. The CWG is a powerful waveform generator which can generate complementary waveforms with fine control of key parameters such as polarity, dead band and emergency shutdown states. It can save both board space and component cost when driving FETs in motor control and power conversion applications.
The CWG and 16-bit PWMs are core independent peripherals which are coupled with the 10-bit ADCs, comparator and 5-bit DAC to enable closed-loop feedback and control.
The PIC12F157X MCUs are well suited for a wide range of applications, such as indoor/outdoor LED lighting and RGB LED colour mixing; consumer applications such as electric razors and radio controlled toys; and automotive interior LED lighting.
The PIC12F1572 enables communication with an EUSART at the lowest price point in the PIC MCU portfolio. The addition of the EUSART enables general-purpose serial communication and LIN for automotive and industrial control. The integrated 10-bit ADCs enable human-interface/touch applications using Microchip’s capacitive mTouch sensing solution.
Additionally, the PIC12F157X offers non-volatile data storage via High Endurance Flash (HEF) memory. The LF versions feature low-power technology, for active currents of less than 35 μA/MHz and sleep currents down to 20 nA, which is ideal for battery-powered applications.
Microchip’s full suite of development tools supports the PIC12F157X MCUs, including the MPLAB X IDE and the PICkit 3; the 8-bit Low Pin Count Development Kit; MPLAB ICD 3; and PICDEM Lab Development Kit. Microchip has also created the RGB Badge Demonstration Platform and High Resolution RGB LED Colour Mixing Application Note #AN1562 to assist developers in designing lighting applications using the PIC12F157X family.
The PIC12LF1571, PIC12LF1572, PIC12F1571 and PIC12F1572 are all available in 8-pin PDIP, SOIC, MSOP and 3 x 3 mm DFN packages.
