Product details
Overview
R5F523E6AGNF#20 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision industrial sensor signal conditioning, featuring dual 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (PGA gain ×1 to ×128), 2.5 V low-drift voltage reference (10 ppm/°C), four excitation current sources (50–1000 µA), and CAN 2.0B interface compliant to ISO11898-1 at up to 1 Mbps.
For engineers reviewing the R5F523E6AGNF#20 datasheet, R5F523E6AGNF#20 pinout, R5F523E6AGNF#20 application, or R5F523E6AGNF#20 equivalent, this device supports IEC60730-compliant diagnostics for A/D converters, clock accuracy measurement (CAC), RAM self-test assistance, and simultaneous 50/60 Hz rejection - critical for thermocouple, RTD, and load cell measurement systems requiring <10 nV/°C offset drift and ±0.2% current matching.
Technical Context
The R5F523E6AGNF#20 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, delivering 64 DMIPS at 32 MHz. Its analog subsystem integrates two independent 24-bit delta-sigma ADCs with fourth-order sinc filters, selectable normal/low-power modes (7.6–15625 SPS), and inter-unit synchronized start capability.
Digital peripherals include a CAN module (RSCAN) with 16 message boxes, RSPI (16 Mbps), SCI (3 channels), RIIC (400 kbps), and ELC-driven event linking that enables timer-triggered ADC conversions without CPU wake-up - essential for ultra-low-power sensor node operation in deep sleep mode.

FAQ
What is the maximum operating temperature specification for the R5F523E6AGNF#20?
The R5F523E6AGNF#20 is rated for operation from –40°C to +105°C (G-grade), making it suitable for deployment in high-ambient-temperature industrial environments such as motor control cabinets, outdoor metering enclosures, and process automation equipment where thermal derating of standard D-grade parts would otherwise limit performance. This rating is confirmed in Table 1.3 of the R01DS0330EJ0130 datasheet.
Does the R5F523E6AGNF#20 support simultaneous sampling across both 24-bit delta-sigma ADC units?
Yes, the R5F523E6AGNF#20 supports inter-unit A/D conversion synchronized start, allowing DSAD0 and DSAD1 to begin sampling at precisely the same time - critical for coherent multi-sensor measurements like differential pressure or torque-angle correlation. This feature is enabled via the ELC or software trigger and documented in Section 1.1 "Outline of Specifications" under DSAD functionality.
How many excitation current sources does the R5F523E6AGNF#20 provide, and what are their key matching specifications?
The R5F523E6AGNF#20 provides four independent excitation current sources (IEXC0–IEXC3) with programmable output from 50 µA to 1000 µA. Their key matching specs are ±0.2% current matching and 5 ppm/°C drift matching - verified in the "Analog front end (AFE)" section of the datasheet - ensuring minimal ratio error in 3- or 4-wire RTD and bridge sensor configurations.
Can the R5F523E6AGNF#20 perform 50 Hz and 60 Hz noise rejection simultaneously?
Yes, the R5F523E6AGNF#20's delta-sigma ADCs support simultaneous 50 Hz and 60 Hz rejection when configured at specific output data rates (e.g., 10 SPS or 54 SPS), leveraging the fourth-order sinc filter architecture. This capability is explicitly listed in the "Analog functions" section and enables robust operation in globally deployed equipment subject to mixed-line-frequency interference.
Is the R5F523E6AGNF#20 pin-compatible with other members of the RX23E-A Group in the same package?
Yes, all RX23E-A devices in the 40-pin HWQFN (PWQN0040KD-A) package - including R5F523E6AGNF#20, R5F523E6ADNF#20, R5F523E5AGNF#20, and R5F523E5ADNF#20 - share identical pin assignments and electrical characteristics per Table 1.4 and Figure 1.5 of the datasheet, enabling drop-in replacement within the same temperature and memory grade family.
