8-bit MCU'er med integreret konfigurerbar logik

Microchip er nu klar med med nye PIC 8-bit microcontrollere med integreret konfigurerbar logik i 6- til 20-pin pakninger (in english).

Microchip announces new 8-bit PIC microcontrollers (MCUs) in 6- to 20-pin packages that feature configurable logic and a high level of peripheral integration.  The PIC10F(LF)32x and PIC1xF(LF)150x MCUs each feature new peripherals, including Configurable Logic Cells (CLCs), Complementary Waveform Generators (CWGs) and Numerically Controlled Oscillators (NCOs), which introduce new functionality to low pin-count MCUs. 

These general-purpose MCUs expand the reach of the PIC10F, PIC12F and PIC16F families and support new applications for microcontrollers.  They enable designers to enhance the functionality, reduce design size, and decrease the cost and power consumption for products such as small kitchen appliances; interior automotive lighting; consumer power tools; utility meters and other applications.

The CLC peripherals on the PIC10F(LF)32x and PIC1xF(LF)150x MCUs enable software control of combinational and sequential logic, which increases the on-chip interconnection of peripherals and I/Os, thereby reducing external components, saving code space and adding functionality. 

The CWG works with multiple peripherals to generate complementary waveforms with dead-band control and auto shutdown, which provides improved switching efficiencies. Additionally, 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, Analogue-to-Digital Converter (ADC), and up to 4 Pulse-Width Modulation (PWM) peripherals.  An integrated temperature-indicator module enables low-cost temperature measurements.

Development is supported by the PICDEM Lab Development Kit (DM163045), which includes samples of both the PIC10F322 and PIC16F1507 MCUs.  Additionally, the F1 Evaluation Platform (DM164130-1) 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, which streamlines 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 can be downloaded from Microchip’s Web site at: http://www.microchip.com/get/NWUN

The new MCUs are also compatible with Microchip’s standard development tools, including the PICkit 3 Debugger/Programmer, as well as the MPLAB® IDE, MPLAB REAL ICE In-Circuit Emulator and MPLAB ICD3 In-Circuit Debugger, and the Microchip and HI-TECH C compilers.

PIC10F(LF)32x and PIC1xF(LF)150x MCUs are available in a range of 6- to 20-pin SOT–23, PDIP, MSOP, TSSOP, DFN and QFN packages.
