September 22, 2014 - Microchip Technology announced PIC16LF1554/9 8-bit PIC MCU that includes 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. Additionally, 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. These features, combined with the low cost and small footprint of the PIC16LF1554/9, make it well suited for a wide range of applications in the consumer-electronic (e.g., remote controls, audio players, cell phone accessories, small appliances, wearable devices such as headphones, watches and fitness wristbands), medical (e.g., blood-pressure monitors and wearable heart-rate monitors), automotive markets (e.g., automotive interior controls and control panels) and industrial markets (e.g., RFID and sensors), among others. Microchip’s full suite of development tools support the PIC16LF1554/9 MCUs, including the MPLAB® X Integrated Development Environment (IDE), PICkit 3 (part # PG164130, $47.95), MPLAB XC8 Compiler for 8-bit PIC MCUs and MPLAB® Code Configurator. Pricing & Availability 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.
