Texas Instruments (TI) has announced the lowest-power MCUs with an on-chip LCD controller within a new family of ultra-low-power MSP430 microcontrollers (MCUs) and a new low-cost LaunchPad rapid prototyping kit that provide all the advantages of non-volatile FRAM in a small memory footprint.
The new MSP430FR4x/FR2x MCUs include 60 capacitive-touch-enabled general-purpose input/output (GPIO) pins so developers can create flexible ultra-low-power products for home automation systems, household appliances, remote controls, energy harvesting applications and many more.
The MSP430FR4x series rounds out TI’s portfolio of ultra-low-power MCUs with integrated LCD support on-chip. The new MCU featured on the MSP-EXP430FR4133 LaunchPad kit includes a segmented LCD driver with software-configurable LCD pins to enable quick and easy hardware layout and an integrated charge pump that allows the LCD contrast level to be maintained even when the MCU is in low-power modes.
The LCD controller can drive up to 256 segments to support large displays used in panel meters and portable health and fitness equipment. TI’s continued focus on ultra-low-power consumption enabled the development of the MSP430FR4x devices, which are the lowest-power MCUs with LCD in the industry. The MSP430FR4133 LaunchPad is immediately available so developers can jump start LCD-based designs quickly.
