Product details
Overview
R5F523E6ADFL#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensor systems, featuring dual 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (gain = 1–128), 2.5 V low-drift voltage reference (10 ppm/°C), four excitation current sources (50–1000 µA), and integrated CAN 2.0B interface. It operates at up to 32 MHz with 256 KB flash, 32 KB SRAM, and 8 KB data flash, supporting IEC60730-compliant diagnostics.
For engineers reviewing the R5F523E6ADFL#30 datasheet, R5F523E6ADFL#30 pinout, R5F523E6ADFL#30 application, or R5F523E6ADFL#30 equivalent, this MCU delivers deterministic real-time control, synchronized multi-channel A/D conversion, low-power operation down to software standby mode, and hardware-assisted self-test functions critical for certified industrial instrumentation and smart sensor nodes.
Technical Context
The R5F523E6ADFL#30 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and inter-unit synchronized start capability - enabling precise differential measurements of thermocouples, RTDs, and strain gauges. Its analog front end includes a bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2), low-side switch (10 Ω max), and voltage fault detectors for reference, input, and excitation paths.
Digital subsystems include a 32-bit RXv2 CPU core (64 DMIPS @ 32 MHz), FPU compliant with IEEE754 single-precision, memory protection unit (MPU), event link controller (ELC) for interrupt-free peripheral chaining, and dedicated modules for CAN, SCI, RSPI, and RIIC - all clocked independently via configurable PCLK domains (PCLKA/B/D).

FAQ
What is the maximum effective resolution of the R5F523E6ADFL#30's delta-sigma ADCs?
The R5F523E6ADFL#30 achieves up to 23-bit effective resolution in its 24-bit delta-sigma A/D converters when operating in normal mode at 7.6 SPS with gain = 1. This is confirmed in the datasheet (R01DS0330EJ0130, Page 1) and reflects actual measured performance after sinc4 filtering and calibration, not theoretical bit count.
Does the R5F523E6ADFL#30 support simultaneous sampling across both delta-sigma ADC units?
Yes, the R5F523E6ADFL#30 supports inter-unit synchronized A/D conversion start via software trigger or ELC event. This ensures deterministic phase alignment between DSAD0 and DSAD1 - essential for multi-sensor applications like 3-phase power measurement or differential bridge configurations.
What are the supported excitation current values on the R5F523E6ADFL#30?
The R5F523E6ADFL#30 provides four programmable excitation current sources (IEXC0–IEXC3) with six selectable output levels: 50 µA, 100 µA, 250 µA, 500 µA, 750 µA, and 1000 µA. Current matching is ±0.2% and drift matching is 5 ppm/°C, as specified in the analog front-end section (Page 4).
Is the R5F523E6ADFL#30 pin-compatible with other RX23E-A group members in the same package?
Yes, the R5F523E6ADFL#30 uses the 48-pin LFQFP (PLQP0048KB-B) package and shares identical pin assignments with other 48-pin RX23E-A variants like R5F523E5ADFL#30 and R5F523E6AGFL#30 - enabling drop-in replacement where memory or temperature grade differences are acceptable.
How does the R5F523E6ADFL#30 meet IEC60730 Class B requirements?
The R5F523E6ADFL#30 integrates hardware-assisted self-test features required for IEC60730 compliance, including RAM test assistance via DOC, A/D converter offset/gain calibration, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) disconnect detection, and analog input disconnect assist - all documented in Section 1.1 of the datasheet.
