Microchip adds configurable logic to 8-bit PICs

Microchip Technology’s latest 8-bit PIC microcontrollers feature configurable logic for the first time. 

The configurable logic cells on the PIC10F(LF)32X and PIC1XF(LF)150X microcontrollers can be used for software control of combinational and sequential logic for on-chip interconnection of peripherals and I/Os. 

The 6- and 8-pin MCUs also include new peripherals such as complementary waveform generators (CWGs) and numerically-controlled oscillators (NCOs).

“This is functionality that was not possible before with low pincount MCUs,” claimed Micochip. 

The CWG peripheral works with multiple peripherals to generate complementary waveforms with dead-band control and auto shutdown, which provides improved switching efficiencies. 

The NCO peripheral enables linear frequency control and high resolution, which is required for applications such as lighting ballast, tone generation and other resonant control circuits. 

The MCUs also feature low power consumption, with currents of less than 30 µA/MHz in active mode, and less than 20 nA in sleep; as well as an on-chip 16 MHz internal oscillator, Analog-to-Digital Converter (ADC), and up to 4 Pulse-Width Modulation peripherals.  An integrated temperature-indicator module enables low-cost temperature measurements.

“These new MCUs expand the reach of the PIC10F, PIC12F and PIC16F families, enabling new applications for microcontrollers that didn’t exist before,” said Steve Drehobl, v-p of Microchip’s security, microcontroller and technology development division.  

Target applications are white good, automotive and industrial meters.

To facilitate application development, the PICDEM Lab Development Kit (part # DM163045, $134.99) now includes samples of both the PIC10F322 and PIC16F1507 MCUs. 

The PIC10F(LF)320 and PIC10F(LF)322 MCUs are available in a 6-pin SOT-23 package, as well as 8-pin PDIP and 2 mm x 3 mm DFN packages.  The PIC12F(LF)1501 MCU will be available in 8-pin PDIP, SOIC, MSOP and 2 mm x 3 mm DFN packages, and the PIC16F(LF)1503 MCU in 14-pin PDIP, SOIC and TSSOP packages, as well as a 3 mm x 3 mm QFN package.  The PIC16F(LF)1507 MCU is available in 20-pin SSOP, PDIP, SOIC, and 4 mm x 4 mm QFN packages, as will the PIC16F(LF)1508/9 MCUs, when available.

The F1 Evaluation Platform (part # DM164130-1, $39.99) is available for development with enhanced mid-range core 8-bit PIC MCUs, including the PIC1XF(LF)150X family. 

Also available is a free CLC Configuration Tool, to streamline the setup process of the CLC module by simulating the functionality of the registers and combinational logic in a graphical user interface (GUI). 

This tool is available today and can be downloaded from Microchip’s Web
