Microchip PIC16LF190X microcontrollers

Microchip has expanded its 8-bit segmented LCD microcontroller family with five devices - the PIC16LF1902/3/4/6/7 (PIC16LF190X).

The PIC16LF190X family supports many general-purpose applications and enables the implementation of LCD into low-power and cost-sensitive designs, such as security tokens, smart cards, medical devices, home appliances, key fobs or any application involving a segmented LCD.

Featuring eXtreme low-power technology for sleep currents down to 20 nA and a typical active current of 35 µA per MHz, the devices extend battery life, while maintaining accurate timing with a RTC and driving a segmented LCD.

The MCUs provide an optimised feature set, including up to 14 KB of flash program memory, up to 512 B of RAM, up to 14 10-bit analog-to-digital converter channels, serial communication, temperature indicator and the capability to drive up to 116 LCD segments.

With the addition of XLP technology for extended battery life, and capabilities such as using the integrated temperature indicator to provide crystal-accuracy compensation, low-power RTC support and low voltage-detect support using the internal ADC and voltage reference, the MCUs enable low-cost LCD solutions for a multitude of portable devices.
