MCUs enable LCD implementation into designs

Featuring Extreme Low Power (XLP) technology, with sleep currents down to 20nA and a typical active current of 35mA/MHz, the MCUs extend battery life, while maintaining accurate timing with a RTC and driving a segmented LCD.

Incorporating Microchip's Enhanced Mid-range architecture, the PIC16LF190x range provides features and performance without incurring the cost of unused peripherals.

The optimised feature set integrates up to 14kB of Flash programme memory, up to 512 bytes of RAM and up to 14 10-bit Analogue-to-Digital Converter (ADC) channels, as well as serial communication and the capability to drive up to 116 LCD segments.

The MCUs also feature XLP technology for extended battery life and capabilities such as an integrated temperature indicator to provide crystal-accuracy compensation, as well as support for low-power RTC and low-voltage detect using the internal ADC and voltage reference.

The PIC16LF1902, PIC16LF1903 and PIC16LF1906 MCUs are available in 28-pin SPDIP, SOIC, SSOP and 4 x 4mm UQFN and die packages, while the PIC16LF1904 and PIC16LF1907 MCUs feature 40-pin PDIP, 5 x 5mm UQFN and die packages, as well as a 44-pin TQFP.
