This unique A/D converter configuration enables more efficient sensor acquisition and brings advanced touch sensing techniques to environments with extreme noise levels, low-power applications, matrix keypads, and water-resistant designs.
The 14- and 20-pin PIC16LF1554/9 microcontrollers combine up to 17 A/D conversion channels with hardware-driven CVD modules to implement capacitive sensing and other input-stage sampling applications with minimal software overhead. Specifically, the hardware CVD reduces the code required to implement capacitive touch sensing by more than 40%. These devices also include up to 14 KB Flash/512 Bytes RAM, an internal
32 MHz oscillator, and two PWM modules, as well as I2C™, SPI, and EUSART for communication. They also offer eXtreme Low Power (XLP) features with active and sleep currents of 35 µA/MHz and 30 nA, respectively, for applications where energy conservation is paramount. These characteristics, along with the low cost and small size of the PIC16LF1554/9, make them suitable for a wide variety of applications in consumer electronics, such as remote controls, audio players, mobile phone accessories, small household appliances, wearable devices such as headphones, watches and fitness trackers; in medical applications such as blood pressure monitors and portable heart rate monitors; in the automotive market for in-cabin controls and control panels; and in industrial markets such as RFID and sensors; as well as other applications.
The entire Microchip development tools suite offers support for the PIC16LF1554/9 microcontrollers, including the MPLAB® X Integrated Development Environment (IDE); the PICkit™ 3 (PG164130) priced at $44.95; the MPLAB XC8 compiler for 8-bit microcontrollers; and the MPLAB® code configurator.
The PIC16LF1554 microcontrollers are now available for sampling and production in 14-pin PDIP, TSSOP, and SOIC packages, and 16-pin QFN (4 x 4 x 0.9 mm) packages. The PIC16LF1559 microcontrollers are available for sampling and production in 20-pin PDIP, SSOP, and QFN (4 x 4 x 0.9 mm) packages.
