Renesas Electronics Corporation introduced the RA2L2 microcontroller (MCU) group with ultra-low power consumption and the industry's first support for the new USB-C Revision 2.4 standard. Based on a 48-MHz Arm Cortex M23 processor, the new MCUs offer a rich feature set that makes them ideal for portable devices and PC peripheralals such as gaming mice and keyboards. The new USB Type-C Cable and Connector Specification Release 2.4 has reduced voltage detection thresholds (0.613V for 1.5A source, and 1.165V for 3.0A source).
The RA2L2 MCUs are the industry's first MCUs to support these new levels. The RA2L2 MC Us employ proprietary low-power technology that delivers 87.5 uA/MHz active mode and software standby current of just 250nA. They also offer an independent operating clock for the low-power UART, which can be used to wake up the system when receiving data from WiFi and/or Bluetooth®?
LE modules. Along with the USB-C support, this combination of features makes the RA2L2 the premier solution available for portable devices such as USB data loggers, charge cases, barcode readers and other products. In addition to USB-C with CC detection up to 15W (5V/3A) and USB FS support, the new MCUs offer LP UART, I3C, and CAN interfaces, giving designers the ability to reduce component count, saving cost, board-space and power consumption.
They also ensure system costs remain low by reducing external components, and they offer the same low-power characteristics as popular RA2L1 devices. Key Features of the RA2L2 MCUs: Core: 48 MHz Arm Cortex-M23; Memory: 128-64 KB Flash, 16 KB SRAM, 4 KB Dataflash; Peripherals: USB-C, USB-FS, CAN, Low Power UART, SCI, SPI, I3C, I2S, 12-bit ADC (17-channel), Low Power Timer, Real-Time Clock, High-Speed On-chip Oscillator (HOCO), Temp Sensor; Packages: 32-, 48- and 64-pin LQFP; 32- and 48-pin QFN; Security: Unique ID, TRNG; Wide Ambient Temperature Range: Ta = -40degC to 125degC; Operating Voltage: 1.6V - 5.5V; USB Operating Voltage: 3.0V to 3.6V to 3.6V.
