MCUs for appliance, consumer and automotive market

Featuring 7 and 14KB of on-chip Flash memory, respectively, and up to 1K RAM, the devices are said to be the highest-memory PIC MCUs in eight- and 18-pin packages.

The LF versions feature Extreme Low Power (XLP) Technology, for active currents of less than 40uA/MHz and sleep currents down to 20nA.

With their high level of peripherals and features, including Mtouch capacitive touch-sensing and multiple communications peripherals, these general-purpose MCUs are suited for a range of applications in the appliance - coffee makers, blenders, dishwashers; consumer - battery chargers, vacuum cleaners, printers, remote controls; and automotive markets - LED lighting, keyless entry, body electronics.

Microchip's Extreme Low Power Technology helps to improve overall energy efficiency in a variety of applications.

The PIC12F(LF)1840 and PIC16F(LF)1847 MCUs are highly integrated, featuring multiple PWMs with independent time bases, a LIN-capable Eusart and up to two I2C/SPI interfaces.

The on-chip, 32-level voltage reference can be used as a simple digital-to-analogue converter and the Data Signal Modulator enables designers to create custom bit patterns using a range of inputs.

The PIC12F(LF)1840 MCUs are supported by the Pickit 2 Low Pin Count Demo Board, while the PIC16F(LF)1847 MCUs are supported by the Pickit 18-pin Demo Board.

All of the devices are supported by the Pickit 3 and MPLAB ICD 3 debugger/programmers, as well as the Picdem Lab Development Kit.

The latter comes complete with a development board containing five popular eight-bit PIC MCUs; a bag of discrete components; a debugger/programmer and a CD containing a user's guide, labs and application examples.
