Renesas has introduced a brand new entry in its RA0 microcontroller household, bringing capability contact to the ultra-low-power vary for the primary time with the RA0L1.
“The RA0L1 combines the industry-leading energy consumption and cost-effectiveness of our RA0 Sequence MCUs [Microcontroller Units] with our unmatched capacitive contact expertise and instruments,” says Renesas’ Daryl Khoo of the corporate’s newest microcontroller launch. “We look ahead to the various revolutionary contact interface options that our prospects will create utilizing these gadgets.”

The RA0L1 relies on a 32-bit Arm Cortex-M23 core, designed for a small footprint and low vitality draw, operating at as much as 32MHz, with 16kB of static RAM (SRAM) and both 32kB or 64kB of flash reminiscence relying on mannequin. There is a 12-bit analog to digital converter with temperature sensor and inner reference voltage, three UART, two asynchronous UARTs, six simplified SPI, six simplified I2C, and two commonplace I2C buses, and timers together with an eight-channel 16-bit timer array unit and a 32-bit interval timer cut up into 4 eight-bit channels plus a real-time clock (RTC).
The most important stand-out function in comparison with the remainder of the RA0 vary, although, is the RA0L1’s human machine interface capabilities: it is the primary within the household to incorporate on-board capacitive contact assist, with a controller delivering as much as 24 channels and as much as eight managed present drive ports to cut back the general invoice of supplies for touch-sensitive initiatives.

Different options embody a real random quantity generator (TRNG), flash entry window and browse safety capabilities, distinctive per-chip identifiers, invalid reminiscence entry safety, A/D check capabilities, a cyclic redundancy verify (CRC) calculator, SRAM parity verify, register write safety, output degree detection, and frequency detection.
Extra info on the elements, which at the moment are accessible, could be discovered on the Renesas web site; the corporate has additionally introduced the FPB-RA0L1 fast prototyping board at $15.34 — and, as is common, has partnered the brand new chips with different elements in its catalog to create a reference design, on this case a capacitive-touch distant management with gesture assist.
