Microchip’s new 8-bit PIC microcontrollers offer automated touch sensing

Microchip has announced the expansion of its 8-bit eXtreme low Power (XLP) Enhanced Midrange Core PIC microcontrollers (MCUs), with the new PIC16F1512/13 devices. These 28-pin MCUs offer a combination of advanced digital and analogue peripherals, combined with XLP for the extended battery life required by many applications. These features make the general-purpose PIC16F1512/13 MCUs suitable for a broad range of applications in the appliance, medical, consumer, automotive and many other markets.

In addition to industry-leading active current down to 30 µA/MHz and sleep current down to 20 nA, these MCUs integrate a 17×10-bit ADC, EUSART, I2C/SPI, two Capture Compare PWMs, 7 KB Flash and 256B RAM.

Compared to other members of the PIC16F151X family, these two new devices deliver increased analogue capability, including a 10-bit Analogue-to-Digital Converter (ADC) with hardware Capacitive Voltage Divider (CVD) support for implementing mTouch capacitive touch sensing. 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 PIC16F1512/13 MCUs are supported by Microchip’s full suite of standard development tools, including the free MPLAB X Integrated Development Environment (IDE) by Microchip’s F1 Evaluation tools, including the F1 Evaluation Platform (DM164130-1).

The PIC16F1512 and PIC16F1513 MCUs are available now for sampling and volume production in 28-pin SSOP, SOIC, SPDIP and 4 x 4 x 0.5 mm UQFN packages.
