The unique dual-ADC configuration of Microchip’s new 8-bit PIC16LF1554/9 microcontrollers enables efficient sensor acquisition and adds support for advanced touch-sensing even in noisy operating environments, as well as in hand-held and water-resistant designs. The new 8-bit PIC16LF1554/9 microcontrollers integrate two independent 10-bit 100K samples per second Analogue-to-Digital Converters (ADC), which offer up to 17 ADC channels, with hardware Capacitive Voltage Dividers (CVD) for advanced touch-sensing.

The automated hardware CVD provides capacitive sensing and other frontend sampling functions whilst cutting touch-sensing code by more than 40% to minimise software overhead.
Offered in a choice of compact 14-, 16- and 20-pin packages, the PIC16LF1554/9 also combine up to 14 KB Flash and 512 Bytes RAM with a 32 MHz internal oscillator and two PWM modules. I2C™, SPI and EUSART interfaces provide flexible connectivity, whilst eXtreme Low Power (XLP) technology enables these MCUs to be used in handheld or other battery-powered applications.
Key facts:
- Unique dual-ADC configuration
- Reduced software overhead for touch-sensing
- Low cost & low power consumption
