Introduction to the MSP430FR4x/FR2x microcontrollers

The MSP430 ultra-low-power microcontroller family now includes the MSP430FR4x/FR2x series of MCUs. The MSP430FR4x MCU series offers the world's lowest power microcontrollers with an on-chip 256-bit segmented liquid crystal display controller, consuming as little as 900 nA in standby.

The built-in charge pump also enables maintained LCD contrast when the MCUs are in low-power modes. Plus, with software configurable LCD control pins, hardware layout is simplified. Beyond the LCD, the MSP430FR4x and MSP430FR2x microcontrollers also offer unmatched flexibility with up to 16 KB unified non-volatile FRAM memory and up to 60 IO pins.

These devices also feature analogue peripherals like a 10bit ADC and special IR Modulation Logic for simplified design in applications such as remote controllers. These FR4 and FR2 devices feature a comprehensive ecosystem for quick evaluation and shortened development cycles. The new MSP430FR4133 device is available on a new LaunchPad Development Kit with an on-board segmented display for getting started for under $20.
