Low-cost 8-bit MCU for low power embedded apps

Microchip Technology Inc. has expanded its 8-bit segmented LCD microcontroller (MCU) family with five new devices-the PIC16LF1902/3/4/6/7 (PIC16LF190X) MCUs. The PIC16LF190X family targets 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. These MCUs feature sleep currents down to 20 nA, and a typical active current of 35 microamperes per MHz.

The feature set includes up to 14 KB of Flash program memory, up to 512 Bytes of RAM, up to 14 10-bit Analog-to-Digital Converter (ADC) 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 utilizing the integrated temperature indicator to provide crystal-accuracy compensation, low-power RTC support and low voltage-detect support utilizing the internal ADC and voltage reference, the MCUs enable low-cost LCD solutions for a multitude of portable devices, says Microchip.

"With industry-leading low power and an optimised feature set, the PIC16LF190X family is designed for any low-power segmented LCD or general-purpose application," said Steve Drehobl, vice president of Microchip's Security, Microcontroller & Technology Development Division.
