NXP has launched the MCX A34 mixed-signal Arm Cortex-M33 industrial MCU, an upgrade of the MCX A14x and MCX A15x MCUs, which were introduced in 2024.

The MCUs come with SMS (SNOOZE Mode Sequencer), which allows dynamic LCD segment display without CPU intervention. By offloading tasks to the SMS, the devices minimise CPU wake-ups and contribute to ...

Renesas Electronics has introduced the new 16-bit RL78/L23 microcontroller (MCU) group, expanding its low-power RL78 family.
