Segmented displays are used in a wide variety of applications, ranging from meters to portable medical devices to thermostats to exercise equipment. Microcontrollers (MCUs) with integrated LCD drivers can directly drive segmented displays with letters, numbers, characters and icons. Developed to meet the low power design requirements, these MCUs are easy and scalable solutions that help extend battery life in your LCD applications. We also offer a family of LCD Analog-to-Digital Converters (ADCs) and a stand-alone LCD driver.

MCUs with Integrated LCD Controller

Our MCUs with integrated LCD drivers can directly drive segmented displays with letters, numbers, characters and icons with up to 512 segments. These MCUs meet low-power design requirements, including driving the LCD display in sleep mode and software contrast control for boosting or dimming.

LCD Display ADCs

Our  LCD display ADCs are complete data acquisition systems that directly drive multiplexed LCDs. They feature a dual slope ADC, seven segment decoders, polarity and digit drivers, a voltage reference and a clock circuit. These devices are useful for panel meter, digital multimeters or instrumentation applications.

Stand-Alone LCD Driver

The AY0438 stand-alone LCD driver includes an on-chip oscillator and can drive up to 32 segments of arbitrary configuration. It is basically a simple-to-use smart peripheral with only three control lines. The AY0438 can be used in a variety of industrial, consumer, telecom and automotive segmented displays.

Featured Product: PIC24F ‘GU/GL/GP' MCUs with Core-Independent Autonomous Animation


Animations like alternating between displays, blinking and blanking of pixels are common in most LCDs. The PIC24F ‘GU/GL/GP’ family of MCUs features an integrated LCD driver with autonomous animation to offload most of these animation routines from the CPU. This allows you to enable animation in power-saving modes while the CPU is in doze, idle or sleep mode.
