Microchip Technology Inc. has unveiled several new 8bit PIC microcontrollers that feature active currents of less than 50?A/MHz and sleep currents down to 20nA. The PIC12F182X MCUs extend Microchip's Enhanced Mid-range 8bit core product line into the 8-pin segment, and include mTouch capacitive touch-sensing, and communications peripherals.

The PIC16F19XX MCUs feature a broad range of peripherals, such as mTouch capacitive touch-sensing module, LCD drive, multiple communications and more pulse-width modulator (PWM) peripherals. All of these general-purpose MCUs are well-suited for applications in the appliance, consumer, industrial and automotive markets, among others.

nanoWatt XLP technology remains the standard for battery-friendly MCUs, which, combined with the extremely low active-current consumption of these new MCUs, improves overall energy efficiency to levels currently not readily available. Microchip's Enhanced Mid-range 8bit architecture provides an up to 50 percent increase in performance, and 14 new instructions that result in up to 40 percent better code execution over previous-generation 8bit PIC16 MCUs. The PIC1XF182X MCUs include dual I?C/SPI interfaces, multiple PWM channels with independent time bases, a data signal modulator, and other peripherals that enable designers to combine many functions into a single MCU. The PIC16F19XX MCUs provide up to 28Kbyte of flash program memory and numerous enhanced capabilities. The on-chip LCD drive supports up to 184 segments and provides a low-power drive mode for increased efficiency. The MCUs also include up to five PWM channels with independent time bases for controlling various motor types and peripherals.

"With active current of less than 50?A per MHz, Microchip has set the new industry benchmark for low-power microcontrollers," said Tony Massimini, chief of technology with Semico Research Corp. "These low active currents, plus sleep currents down to 20nA and the industry-leading number of peripherals integrated onto the PIC12F182X, PIC16F182X and PIC16F19XX MCUs, enable engineers to create battery-friendly designs that also incorporate capacitive touch sensing, LCD, communications and other functions, which will help differentiate their products in the marketplace."

Steve Drehobl, VP of Microchip's security, microcontroller and technology development division, said, "Microchip further solidifies its low-power leadership with the introduction of the PIC1XF182X and PIC16F19XX 8bit microcontrollers. The new MCUs represent a significant expansion of our enhanced Mid-range 8bit core product family, which provides additional memory, peripherals and performance. The improvements to the active power consumption in combination with our XLP technology set the industry standard for low power operation in small 8bit MCUs."
