8-bit MCUs

22 June 2011 DSP, Micros & Memory

Microchip has added to its Enhanced Mid-Range core 8-bit PIC 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 KB 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, helping to improve overall energy efficiency with active currents of less than 40 μA/MHz and sleep currents down to 20 nA. The devices 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 DAC, whilst the data signal modulator enables designers to create custom bit patterns using a broad spectrum of inputs.
