Renesas Electronics has introduced the launch of a brand new 32-bit microcontroller in its RX household, this time bringing with it a high-precision analog front-end (AFE) — providing 24-bit decision at as much as eight instances the pace of its predecessor.
“With the addition of the RX23E-B which comes with an AFE sensor interface, we are able to now serve a broad vary of sensing functions from mid- to high-end programs,” claims Sakae Ito, vice chairman of Renesas’ Web of Issues Platform Enterprise Division, of the brand new half. “We are going to proceed to increase our product choices to satisfy the rising wants of battery-powered and wi-fi sensors that demand low energy consumption.”

The stand-out characteristic of the RX23E-B is its analog front-end (AFE), a 24-bit delta-sigma analog-to-digital converter (ADC) which delivers a claimed sampling price of 125 thousand samples per second (125kS/s) — an eightfold enchancment on the corporate’s earlier RX23E-B, Renesas says, with a 31.25kS/s variant accessible providing a decreased energy draw. It is also much less inclined to noise at low voltage ranges, the corporate claims, delivering root-mean sq. (RMS) noise of 0.18µVrms at 1kS/s — a 3rd of the RX23E-A.
Along with the AFE, the chip features a single 32-bit RXv2 processor core working at as much as 32MHz and together with directions for accelerating digital sign processing (DSP) workloads and floating-point arithmetic, 32kB of static RAM (SRAM), 256kB of flash reminiscence plus 8kB for background information storage, a 16-bit digital-to-analog converter (ADC), a 12-bit eight-channel analog-to-digital converter (ADC), seven UART, one SPI, one I2C, and one CAN bus, a 40-segment LCDC interface for an LCD show, a watchdog timer, 16-bit six-channel PWM timers, eight-bit four-channel and 16-bit two-channel general-purpose timers, a low-power timer, and a real-time clock (RTC).

To show its capabilities, Renesas has designed a reference implementation for the RX23E-B in a stress management system — utilizing the floating-point unit on the chip to speed up filter calculations and proportional–integral–spinoff (PID) management calculations, whereas combining it with a low drop-out (LDO) regulator and two “Clever Energy Gadget” digital relays to regulate solenoid valves within the system.
The RX23E-B is obtainable to order now, worth on utility, on the Renesas web site; the corporate has additionally launched a “Answer Starter Equipment” for code-free analysis and testing.
