Microchip med nye low-power MCU’er
Nye Microchip 8-bit MCU’er har aktiv strøm på mindre end 50 µA/MHz og integrerer en særdeles bred vifte af periferifunktioner (in english)
Microchip Technology has unveiled several new 8-bit PIC microcontrollers (MCUs) that according to the company sets the industry benchmark for low-power microcontrollers and peripheral integration.
These new MCUs feature active currents of less than 50 µA/MHz and sleep currents down to 20 nA. The PIC12F182X MCUs extend Microchip’s Enhanced Mid-range 8-bit 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 8-bit architecture provides an up to 50% increase in performance, and 14 new instructions that result in up to 40% better code execution over previous-generation 8-bit PIC16 MCUs. The PIC1XF182X MCUs include dual I2C/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 28 KB 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 5 Pulse-Width Modulation (PWM) channels with independent time bases for controlling various motor types and peripherals.
- With active current of less than 50 µA per MHz, Microchip has set the new industry benchmark for low-power microcontrollers, says Tony Massimini, chief of technology with Semico Research Corporation.
- These low active currents, plus sleep currents down to 20 nA 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.
