Toni_McConnel-September 25, 2012

Microchip Technology Inc. has expanded its 8-bit eXtreme low Power (XLP) Enhanced Midrange Core PIC microcontrollers (MCUs) with its new PIC16F1512/13 devices. The 28-pin MCUs offer a combination of advanced digital and analog peripherals, along with XLP for extended battery life. These features make the general-purpose PIC16F1512/13 MCUs ideal for a broad range of applications. Along with 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 PIC16F1512/13 MCUs are supported by Microchip’s full suite of standard development tools, including the free MPLAB X Integrated Development Environment (IDE), the MPLAB PM3 Universal Device Programmer (part # DV007004, $895.00), and the PICkit 3 (part # PG164130, $44.95) and MPLAB ICD 3 (part # DV164035, $189.99) debuggers/programmers. The PIC16F15XX MCUs are also supported by Microchip’s F1 Evaluation tools, including the F1 Evaluation Platform (part # DM164130-1, $39.99) and the F1 Evaluation Kit, which includes the PICkit 3 (part #DV164132, $69.99). Additionally, the MPLAB XC8 Compiler for 8-bit PIC MCUs is available. All of these tools can be ordered today, at http://www.microchip.com/get/NTJN.

The PIC16F1512 and PIC16F1513 MCUs are both available today for sampling and volume production in 28-pin SSOP, SOIC, SPDIP and 4 x 4 x 0.5 mm UQFN packages. Pricing starts at $0.58 each in high-volume quantities.
