Datasheet

Microchip announces an expansion of its 8-bit segmented LCD microcontroller (MCU) family with five new devices combining low-cost LCD control with industry-leading low power consumption. The PIC16LF190x MCUs enable the implementation of LCD into cost-sensitive power-efficient designs, such as security tokens, smart cards, medical devices, home appliances, key fobs and other segmented LCD applications. Featuring eXtreme Low Power (XLP) technology, with sleep currents down to 20 nA and a typical active current of 35 microamperes per MHz, the MCUs extend battery life, whilst maintaining accurate timing with a RTC, and driving a segmented LCD.

Incorporating Microchip’s Enhanced Mid-range architecture, the PIC16LF190x family provides essential features and performance without incurring the cost of unused peripherals. The optimised feature set integrates up to 14 KB 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 PIC16LF190x MCUs can be evaluated with the F1 Evaluation Kit (DM164132), priced at $69.99, and F1 Evaluation Platform (DM164130-1), priced at $39.99, as well as the PICkit™ 3 In-Circuit Debugger (PG164130) at $44.95.

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