Renesas has introduced one other new entry in its microcontroller lineup, the ultra-low-power RA4C1 — that includes an Arm Cortex-M33 core working at as much as 80MHz and an lively energy draw of simply 168µA/MHz.
“Renesas’ RA4C1 group MCUs [Microcontroller Units] provide an unmatched answer for metering purposes, a really massive market that’s rising quickly,” claims Renesas’ Daryl Khoo of 1 potential marketplace for the brand new chips. “It is an instance of our gross sales, advertising and marketing, and engineering groups working along with our prospects to develop the best product for the best market on the proper time.”

The RA4C1 microcontroller chips are constructed round a 32-bit Arm Cortex-M33 core working at as much as 80MHz and that includes Arm’s TrustZone safety subsystem, full with true random quantity generator (TRNG) and hardware-accelerated AES cryptography, and will be specified with 256–512kB of dual-bank flash storage alongside facet 8kB of knowledge flash and 96kB of static RAM (SRAM).
Peripherals embrace low-power UART, CAN FD, SCI, SPI, quad-SPI, I2C buses, plus a 12-bit analog to digital converter (ADC) with an on-chip temperature sensor with a claimed ±1 p.c accuracy, an on-chip LCD controller for low-power segment-based shows, a real-time clock with battery backup, and a low-power timer.

Whereas Renesas has made a lot of the chip’s safety — together with the promise of a RSIP-300 safety engine with remoted subsystem protected by devoted management logic and assist for a 256-bit distinctive key — it is the ability draw that’s more likely to entice most curiosity: the corporate claims a 168µA/MHz lively energy draw and a standby present of below 1.79µA whereas retaining all SRAM contents.
Extra data on the RA4C1 household, together with a “analysis board” for experimenting with the chip, is offered on the Renesas web site; as is common, the corporate has additionally used the brand new half in a “Profitable Mixture” reference design, this time for a wise metering system.
