With wealthy connectivity choices and full-speed USB, it allows compact, cost-efficient designs for information loggers, gaming peripherals, and wireless-enabled functions.
Renesas Electronics has introduced the launch of its new RA2L2 microcontroller (MCU) group, the primary within the business to assist USB Kind-C Specification Revision 2.4. Designed for low-power efficiency, the MCUs goal moveable gadgets corresponding to USB information loggers, cost circumstances, barcode readers, gaming peripherals, and different compact electronics.
These energy-efficient options make it ideally suited for battery-powered functions. The system additionally features a low-power UART with an impartial clock, enabling wake-up performance from wi-fi modules like Wi-Fi or Bluetooth LE. The corporate backs the MCU with its Versatile Software program Package deal (FSP), which incorporates RTOS assist, drivers, middleware, and connectivity options. This permits speedy growth and simplifies code migration throughout Renesas’ RA household.
The important thing options are:
- Powered by 48 MHz Arm Cortex-M23 core
- Built-in full-speed USB
- Reduces want for exterior elements, saving area and price
The RA2L2 microcontroller is designed for ultra-low energy operation, consuming simply 87.5 µA/MHz in energetic mode and solely 250 nA in software program standby. It’s the first MCU to supply native assist for the USB-C Revision 2.4 normal, with up to date voltage detection thresholds of 0.613V for 1.5A sources and 1.165V for 3.0A sources, supporting energy supply as much as 15W (5V/3A). As well as, the RA2L2 encompasses a complete set of communication interfaces together with I3C, CAN, SPI, SCI, and I2S, enabling versatile connectivity whereas minimizing the necessity for exterior elements.
It’s accessible in a number of bundle choices—LQFP and QFN with 32 to 64 pins—and helps a large working voltage (1.6V to five.5V) and temperature vary (-40°C to 125°C).The corporate has additionally bundled the RA2L2 with complementary elements into a number of ready-to-use design options, together with information loggers, gaming keyboards, and toll programs. These “Profitable Mixtures” assist clients scale back design time and speed up market readiness.
