EMBEDDED WORLD: Microchip Technology Inc. unveiled an expanded range of 8-bit PIC microcontrollers with devices that feature active currents of less than 50 A/MHz and sleep currents down to 20 nA.
The PIC12F182X MCUs extend Microchip's enhanced mid-range 8-bit core product line into the 8-pin segment, and include mTouch capacitive touch-sensing, and communications peripherals.
The PIC16F19XX MCUs feature a broad range of peripherals, such as mTouch capacitive touch-sensing module, LCD drive, multiple communications and more pulse width modulator (PWM) peripherals. All of these general-purpose MCUs are suitable for applications in the appliance; consumer; industrial and automotive markets, among others.
The enhanced mid-range 8-bit architecture provides an up to 50 per cent increase in performance, and 14 new instructions that result in up to 40 per cent better code execution over previous-generation 8-bit PIC16 MCUs.
The PIC1XF182X MCUs include dual I2C/SPI interfaces, multiple PWM channels with independent time bases, a data signal modulator, and other peripherals that enable designers to combine many functions into a single MCU.
The PIC16F19XX MCUs provide up to 28 Kbyte of flash program memory and numerous enhanced capabilities. The on-chip LCD drive supports up to 184 segments and provides a low-power drive mode for increased efficiency. The MCUs also include up to five PWM channels with independent time bases for controlling various motor types and peripherals.
Designers can use Microchip's F1 Evaluation Platform for developing with enhanced 8-bit PIC MCUs. The platform includes a 44-pin development board populated with a PIC16LF1937 MCU, prototyping space, 3V LCD glass, support for the PICkit 3 in-circuit debugger/programmer, as well as a motor-control add-on. The PIC16F1937 plug-in module for Microchip's PIC18 explorer board is also available.
Microchip's PICDEM lab development kit can be used with the PIC1XF182X MCUs. The kit comes complete with a development board containing five popular 8-bit PIC MCUs; a bag of discrete components; a debugger/programmer, and a CD containing a User's Guide, labs and application examples.
Microchip's complete suite of standard development tools can also be used with the new MCUs, including the free MPLAB IDE, along with the selection of the HI-TECH C compiler for PIC16 MCUs. The HI-TECH C Lite edition is a free, fully functional compiler with no time limitations. For applications with limited program space, the Standard and PRO editions offer denser code and improved performance.
The PIC1XF182X and PIC16F19XX MCUs are available in DFN, PDIP, QFN, SOIC, TQFP, TSSOP and UQFN packages of varying sizes, from 8- to 64-pins.
