New microcontrollers extend temperature range

14th June 2018


Texas Instruments has announced the addition of new microcontrollers (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 printed circuit board (PCB) size and bill-of-materials (BOM) cost while meeting temperature requirements for sensing and measurement in applications such as smoke detectors, sensor transmitters and circuit breakers. 

Engineers can enjoy more flexibility in their system design with these MCUs, which integrate smart analogue combos – configurable signal-chain elements that include options for multiple 12-bit digital-to-analogue converters (DACs) and programmable gain amplifiers, along with a 12-bit analgue-to-digital converter (ADC) and two enhanced comparators.

Developers can use them for applications that require operation at temperatures as high as 105°C while also benefiting from FRAM data-logging capabilities.

There are more options to select the right memory and processing speed for cost-sensitive applications, which add options to the MSP430 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 MSP430 FRAM MCU portfolio for applications that require up to 256 KB of memory, higher performance or more analogue peripherals.
