New MCUs Are Splendid for Moveable Units resembling Information Loggers and Cost Circumstances
Renesas Electronics Company, a premier provider of superior semiconductor options, launched the RA2L2 microcontroller (MCU) group with ultra-low energy consumption and the business’s first help for the brand new UCB-C Revision 2.4 commonplace. Based mostly on a 48-MHz Arm Cortex M23 processor, the brand new MCUs provide a wealthy characteristic set that makes them ideally suited for transportable units and PC peripherals resembling gaming mice and keyboards.
The brand new USB Kind-C Cable and Connector Specification Launch 2.4 has decreased voltage detection thresholds (0.613V for 1.5A supply, and 1.165V for 3.0A supply). The RA2L2 MCUs are the business’s first MCUs to help these new ranges.
The RA2L2 MCUs make use of proprietary low-power expertise that delivers 87.5 µA/MHz lively mode and software program standby present of simply 250nA. In addition they provide an impartial working clock for the low-power UART, which can be utilized to get up the system when receiving information from Wi-Fi and/or Bluetooth LE modules. Together with the USB-C help, this mix of options makes the RA2L2 the premier resolution obtainable for transportable units resembling USB information loggers, cost instances, barcode readers and different merchandise.
Along with USB-C with CC detection as much as 15W (5V/3A) and USB FS help, the brand new MCUs provide LP UART, I3C, and CAN interfaces, giving designers the power to scale back part depend, saving price, board-space and energy consumption.
The RA2L2 MCUs are supported by Renesas’ Versatile Software program Bundle (FSP). The FSP permits sooner software growth by offering all of the infrastructure software program wanted, together with a number of RTOS, BSP, peripheral drivers, middleware, connectivity, and networking in addition to reference software program to construct advanced AI, motor management and cloud options. It permits prospects to combine their very own legacy code and selection of RTOS with FSP, thus offering full flexibility in software growth. The FSP eases migration of present IP to and from different RA units.
“The RA2L2 Group MCUs are our first to understand full-speed USB together with USB-Kind C connector help. In addition they guarantee system prices stay low by lowering exterior elements, and so they provide the identical low-power traits as our standard RA2L1 units,” mentioned Daryl Khoo, Vice President of Embedded Processing Advertising Division at Renesas. “These new units show our dedication and talent to shortly ship the options our prospects require.”
