Texas Instruments - First MCU with a configurable low-leakage transimpedance amplifier (MSP430FR2311)

 1097. To enable designers to extend battery life in sensing and measurement applications, Texas Instruments has developed the MSP430FR2311 microcontroller (MCU) – the industry ’s only MCU with integrated low-leakage transimpedance amplifier (TIA), only Consumes 50pA. The new microcontroller is an extension of the ultra-low-power MSP430 MCU family, with 20 times the leakage current of alternative voltage and current detection solutions, and provides analog and storage technologies without sacrificing battery life or board space Configurability. A highly integrated MCU solution with configurable analog functions can help developers simplify their schematics and save up to 75% of PCB space. The MSP430FR2311 MCU allows developers to connect to a variety of sensors through its analog integration including ADCs, operational amplifiers, comparators, and TIAs. The solution also integrates ferroelectric random access memory (FRAM) technology and eliminates the need for a single 3.5mm x 4mm package to provide on-board crystals. This single-chip solution will reduce design complexity and overall project development time. The MSP430FR2311 MCU allows developers to choose the desired amplifier configuration (in-phase, inverting, or transimpedance) and expand their application by choosing the amount of memory to allocate to application code or data, eliminating the flash-to-RAM ratio boundary. Customers can use the Code Composer Studio integrated development environment (IDE) and the MSP430FR2311 MCU LaunchPad development kit supported by IAR Embedded WorkBench to get started in minutes. Customers can then explore application implementation using the MSP430FR2311 smoke sensing subsystem reference design (launched in the second quarter of 2016), which uses photodiode and TIA configurations for current sensing. In addition, users developing systems for medical health, fitness, building automation, and personal electronic devices can take advantage of this TI Design Reference Design (TIDA-00242) to further extend battery life, which uses TI energy in MSP430FR2311 MCU based systems Collect IC (bq25570). MSP430G2x MCU users currently using 2KB and 4KB devices can easily migrate their designs to the MSP430FR2311 MCU and take advantage of higher performance through non-volatile FRAM and higher analog integration including op amps, ADCs, and comparators. Users can review the MSP430F2xx and MSP430G2xx Series Migration Guides to learn how to easily move between series when more analog capabilities are needed.
