Microchip Technology Inc. has announced new additions to its PIC12/16LF155X 8-bit microcontroller (MCU) family with the PIC16LF1554 and PIC16LF1559 devices. The new devices include two independent 10-bit 100K samples per second Analog-to-Digital Converters (ADC) with hardware Capacitive Voltage Divider (CVD) support for capacitive touch sensing. This ADC configuration enables more efficient sensor acquisition and assists with advanced touch-sensing techniques for extremely noisy environments, low-power applications, matrix keypads and water-resistant designs.
The 14- and 20-pin PIC16LF1554/9 MCUs combine up to 17 ADC channels with automated hardware CVD modules to implement capacitive sensing and other front-end sampling applications with minimal software overhead. These devices also include up to 14 KB Flash/512 Bytes RAM, a 32 MHz internal oscillator, two PWM modules, along with I2C, SPI and EUSART for communications. They are eXtreme Low Power (XLP) compliant with active and sleep currents of 35 µA/MHz and 30 nA, respectively, for applications where energy conservation is paramount.
The PIC16LF1554 MCUs are available now for sampling and production in 14-pin PDIP, TSSOP, SOIC and 16-pin QFN (4 x 4 x .9 mm) packages. The PIC16LF1559 MCUs are available now for sampling and production in 20-pin PDIP, SSOP and QFN (4 x 4 x .9 mm) packages. Pricing starts at $0.63 each, in 10,000-unit quantities.
