Microchip expands low pin-count, enhanced mid-range 8-bit PIC® MCU family
Key Facts:
• Highest-memory PIC® MCUs in 8- and 18-pin packages
• Rich peripheral-set with mTouch™ capacitive touch sensing
• Extreme low power technology
Microchip has announced the latest additions to the Enhanced Mid-Range core 8-bit PIC® microcontroller (MCU) family with the peripheral-rich, low pin-count PIC12F(LF)1840 and PIC16F(LF)1847. Featuring 7 KB and 14 KB of on-chip Flash memory, respectively, and up to 1 K RAM, the new devices are the highest-memory PIC® MCUs in 8- and 18-pin packages. The LF versions feature eXtreme 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 40 µA/MHz and sleep currents down to 20 nA.
The combination of large memories, low power consumption and a high number of peripherals, such as mTouch™ capacitive touch-sensing and multiple communications peripherals, helps designers to extend battery life, reduce board space and also lower their bill-of-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), whilst 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), whilst the PIC16F(LF)1847 MCUs are supported by the PICkit 18-pin Demo Board (DM164120-4). 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), 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 mm x 3 mm DFN SOIC packages; and the PIC16F(LF)1847 MCUs are offered in 18-pin PDIP, SOIC, SSOP and 4 mm x 4 mm UQFN packages.
