Renesas has introduced one other new household in its microcontroller lineup, this time focusing on USB-connected gadgets like knowledge loggers: the RA2L2, which introduces the vary’s first assist for the USB Kind-C Cable and Connector Specification Launch 2.4 and its decrease voltage detection threshold.
“The RA2L2 group MCUs [Microcontroller Units] are our first to comprehend full-speed USB together with USB-Kind C connector assist. In addition they guarantee system prices stay low by lowering exterior elements, and so they provide the identical low-power traits as our common RA2L1 gadgets,” says Renesas’ Daryl Khoo of the brand new elements. “These new gadgets display our dedication and talent to rapidly ship the options our prospects require.”

The chips are Renesas’ — and, the corporate says, the broader business’s — first to implement the necessities of the USB Kind-C Cable and Connector Specification Launch 2.4, which launched decrease voltage detection thresholds of 0.613V for a 1.5A supply and 1.165V for a 3.0A supply. They embrace assist for USB Full Pace (FS) connectivity and USB Kind-C connectivity with CC detection for an influence draw of as much as 3A at 5V (15W), which Renesas says makes them appropriate for all the pieces from charging instances for headphones and different wearables to USB knowledge loggers, barcode readers, and even gaming peripherals.
The chips function a single Arm Cortex-M23 microcontroller core working at as much as 48MHz, with claimed energy draw of 87.5µA/MHz in energetic mode and a 250nA software program standby draw, with 16kB of static RAM (SRAM) and 64–128kB of flash storage, relying on mannequin, plus 4kB of information flash.

USB apart, peripherals embrace low-power UART (LPUART), SCI, SPI, I3C, I2S, CAN bus, and a 17-channel 12-bit analog to digital converter (ADC), plus a low-power timer, real-time clock (RTC), high-speed on-chip oscillator (HOCO), and built-in temperature sensor, plus a safety subsystem with a singular per-chip identifier and a real random quantity generator (TRNG).
Extra info on the chips is out there on the Renesas product web page; the corporate has additionally launched an analysis board constructed across the half, priced at round $50 relying on provider. As inspiration, the corporate has used the chips in a collection of “Successful Combos” reference designs: a USB knowledge logger, an digital toll system with International Navigation Satellite tv for pc System (GNSS) assist, a gaming keyboard, and a gaming mouse.
