MCUs Offer Configurable Single-Chain Elements to Sense Applications


MCU (Microcontroller) now offers extended operating temperatures up to 105°C, combined with increased analogue integration to meet industrial system requirements

Texas Instruments (TI) announced the addition of new MCUs with integrated signal-chain elements and an extended operating temperature range to its MSP430 value line portfolio.

Benefits of the MSP430FR2355 MCUs

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. It features a powerful 16-bit RISC CPU, 16-bit registers and a constant generator that contribute to maximum code efficiency.


The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode typically in less than 10 µs. The MSP430 ultra-low-power (ULP) FRAM microcontroller platform combines with embedded FRAM and a holistic ultra-low-power system architecture, allowing system designers to increase performance while lowering energy consumption.

Signal-chain configurability

Engineers can enjoy more flexibility in their system design with MSP430FR2355 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 analogue-to-digital converter (ADC) and two enhanced comparators.

Extended temperature range

Developers can use MSP430FR2355 MCUs for applications that require operation at temperatures as high as 105°C while also benefiting from FRAM data-logging capabilities.

MSP430 value line portfolio scalability

Engineers gain more options to select the right memory and processing speed for cost-sensitive applications with it, which add options to the MSP430 value line FRAM MCU family by offering the memory of up to 32 KB and central processing unit (CPU) that 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.
