MCUs – Microchip unveils new low-power 8-bit PIC MCUs with nanoWatt XLP

Chandler, Ariz. – Microchip Technology Inc. has launched a new family of 8-bit PIC microcontrollers (MCUs) featuring nanoWatt XLP technology, which enables extremely low sleep currents.'The high-performance, low-power PIC18F13K22, PIC18LF13K22, PIC18F14K22 and PIC18LF14K22 (PIC18F1XK22) MCUs MCUs are available in 20-pin packages and provide 1.8 to 5.5V operation, with up to 16 Kbytes Flash program memory.

The devices feature an enhanced peripheral set that includes support for mTouch capacitive touch sensing, and are well suited for a variety of general-purpose applications.

nanoWatt XLP technology allows the PIC18LF1XK22 MCUs to operate longer using less power, or with fewer battery changes, by enabling sleep current of 34 nA, typical at 1.8V; Timer1 oscillator currents of 800 nA, typical at 1.8V, 32 kHz; and Watchdog Timer currents of 300 nA, typical at 1.8V.'Most low-power applications require one or more of these features, and nanoWatt XLP Technology combines all of them into one device in the “LF” versions of the PIC18F1XK22 family.

Features provided by the PIC18F1XK22 MCUs include a 64 MHz precision internal oscillator, which lowers total system costs by reducing the number of external components needed for complete designs; Master Synchronous Serial Port (MSSP) with SPI/I2C interface and address masking; 12-channel, 10-bit Analog-to-Digital Converter (ADC); and S/R-latch module that supports mTouch capacitive touch-sensing (up to 4 buttons).

Also included are enhanced Capture/Compare/Pulse-Width Modulation [PWM (ECCP)] with steering capabilities; dual rail-to-rail comparators; programmable Brown Out Reset (BOR); low-power 1.8 to 5.5V operation, with full analog peripheral functionality; and small package options, including 4 mm x 4 mm QFN.

The PIC18F1XK22 MCUs are appropriate for a wide variety of general-purpose applications in the appliance, consumer/home electronic, industrial, automotive, and medical markets.

Microchip offers engineers a complete suite of standard development tools to design with the PIC18F1XK22 microcontrollers.'More information on development tools is available at http://www.microchip.com/developmenttools.

Pricing for the PIC18F1XK22 devices starts at $1.27 each, in 10,000-unit quantities.'All of the devices are available in 20-pin PDIP, SSOP, SOIC and 4 mm x 4 mm QFN packages.'Samples are available at http://sample.microchip.com.'Volume production quantities can be ordered at http://www.microchipdirect.com.For further information, visit Microchip's Web site at http://www.microchip.com/pic18k or http://www.microchip.com/xlp.
