Microchip’s New 8-bit PIC® Microcontrollers Combine High Integration, Low Power and a Highly Efficient Method to Implement Touch Sensing
These new 28-pin MCUs offer a combination of advanced digital and analog peripherals, along with XLP for the extended battery life that many applications require. These features make the general-purpose PIC16F1512/13 MCUs ideal for a broad range of applications in the appliance, medical, consumer and automotive markets, among many others. Along with industry-leading active current down to 30 µA/MHz and sleep current down to 20 nA, these MCUs integrate a 17x10-bit ADC, EUSART, I2C™/SPI, 2x Capture Compare PWMs, 7 KB Flash and 256B RAM.
Compared to other members of the PIC16F151X family, these two new devices deliver increased analog capability, including a 10-bit Analog-to-Digital Converter (ADC) with hardware Capacitive Voltage Divider (CVD) support for mTouch™ capacitive touch sensing implementation. The additional control logic enables automated touch sampling, which reduces software size and lowers CPU usage. It also provides an automatic control of guard-ring drive and a programmable sample-and-hold capacitance to better match larger touch or proximity sensors.
“The new PIC16F1512/13 devices support a wide range of applications that require best-in-industry low-power modes, with the added ability to reduce software overhead and improve performance when touch sensing is required,” said Steve Drehobl, vice president of Microchip’s MCU8 Division.”
