TI has added two MCUs with integrated signal-chain elements and an extended operating temperature range to its MSP430 value line portfolio.
New MSP430FR2355 ferroelectric random access memory (FRAM) MCUs allow developers to reduce PCB size and BOM cost while meeting temperature requirements for sensing and measurement in applications such as smoke detectors, sensor transmitters and circuit breakers.
The MCUs integrate smart analogue combos – configurable signal-chain elements that include options for multiple 12-bit digital-to-analog converters (DACs) and programmable gain amplifiers, along with a 12-bit analog-to-digital converter (ADC) and two enhanced comparators.
Developers can use MCUs for applications that require operation at temperatures as high as 105°C while also benefiting from FRAM data-logging capabilities.
Engineers gain more options to select the right memory and processing speed for cost-sensitive applications with the MCUs, which add options to the value line FRAM MCU family by offering memory up to 32 KB and central processing unit (CPU) speeds up to 24 MHz.
Designers can also scale to the rest of the MEP430 MCU portfolio for applications that require up to 256 KB of memory, higher performance or more analogue peripherals.
