Microchip has announced the latest additions to its enhanced mid-range core 8-bit PIC microcontroller (MCU) range with the peripheral-rich, low pin-count PIC12F(LF)1840 and PIC16F(LF)1847.

Featuring 7KB and 14KB of on-chip Flash memory, respectively, and up to 1,000 RAM, the new devices are claimed to be the highest-memory PIC MCUs in eight- and 18-pin packages.

The LF versions feature Xtreme Low Power (XLP) technology, which remains the industry standard for battery-friendly MCUs, helping to improve overall energy efficiency with active currents of less than 40uA/MHz and sleep currents down to 20nA.

The combination of large memories, low power consumption and a high number of peripherals, such as Mtouch capacitive touch-sensing and multiple communications peripherals, is intended to help designers extend battery life, reduce board space and lower their materials costs in a wide range of applications.

These include appliances such as coffee makers, blenders, dishwashers; consumer electronics such as battery chargers, vacuum cleaners, printers or remote controls; and automotive LED lighting, remote keyless entry and body electronics.

The PIC12F(LF)1840 and PIC16F(LF)1847 MCUs are highly integrated and feature 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 (DAC), while the data signal modulator enables designers to create custom bit patterns using a broad spectrum of inputs.

The PIC12F(LF)1840 MCUs can be evaluated using the PICkit 2 Low Pin Count Demo Board (DM164120-1), priced at USD23.99; while the PIC16F(LF)1847 MCUs are supported by the PICkit 18-pin Demo Board (DM164120-4) priced at USD23.99.

All of the devices are also supported by the PICkit 3 (PG164130) and MPLAB ICD 3 (DV164035) debugger/programmers.

They can also be developed using the PICDEM Lab Development Kit (DM163035), priced at USD124.99, which features five popular 8-bit PIC MCUs; a selection of discrete components; a debugger/programmer; and a CD containing a user’s guide, labs and application examples.

The PIC12F(LF)1840 MCUs are available in 8-pin PDIP, SOIC and 3 x 3mm DFN SOIC packages; and the PIC16F(LF)1847 MCUs are offered in 18-pin PDIP, SOIC, SSOP and 4 x 4 mm UQFN packages.
