STMicroelectronics has cut-down its STM32F7 or STM32H7 MCU lines, which have up to 2Mbyte flash and up to 1Mbyte RAM, to make the pin-compatible ScF7x0 and H7x0 microcontrollers. “These new lines trim embedded flash to the essential, still allowing secure boot, sensitive code and real-time routines to run safely on-chip,” said the firm. Overall, STM32F7 ...

Diodes is aiming at non-isolated mains-powered IoT nodes with an ac-dc power chip that can deliver 60mA at 3.3V. AL17050 is a universal (85-265Vac) universal off-line buck converter with an integrated 500V 30Ω mosfet. Static consumption is 100μA, which my calculator tels me is 24mW at 240V. “The device automatically adjusts to low loads, so it ...

STEF01 is an 8-48V 4A programmable electronic fuse from STMicroelectronics. When connected in series to the main power rail, it protects the load against over-current and over-voltage. Voltage is clamped to a user-defined maximum, preset with external resistors. Excessive current is restricted to the programmed safe limit by controlling the internal power mosfet, and folds-back ...
