Renesas affords one of many first microcontroller households to help USB-C Revision 2.4 with its RA2L2 group of low-power Arm Cortex-M23 MCUs. The up to date USB Sort-C cable and connector specification lowers voltage detection thresholds to 0.613 V for 1.5 -A sources and 1.165 V for 3.0-A sources, enhancing compatibility with newer USB-C cables and units.
Low-power operation makes the RA2L2 MCUs well-suited for moveable units reminiscent of USB information loggers, charging circumstances, barcode readers, and PC peripherals like gaming mice and keyboards. These entry-level MCUs devour simply 87.5 µA/MHz in energetic mode, dropping to 250 nA in software program standby. An impartial UART clock allows wake-up from standby when receiving information from Wi-Fi or Bluetooth LE modules.
Along with USB-C cable and connector detection as much as 15 W (5 V/3A) and USB Full-Velocity help, the MCUs supply a low-power UART, I3C, SSI, and CAN interfaces for design flexibility. The 48-MHz Cortex-M23 core is paired with as much as 128 KB of code flash, 4 KB of knowledge flash, and 16 KB of SRAM.
RA2L2 microcontrollers are actually accessible. Samples and analysis kits may be ordered from the Renesas web site and licensed distributors.
