Renesas R5F523E6AGFL#50

Overview

R5F523E6AGFL#50 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 (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. It operates at 32 MHz with 256 KB flash, 32 KB SRAM, and supports –40°C to +105°C ambient temperature.

For engineers reviewing the R5F523E6AGFL#50 datasheet, R5F523E6AGFL#50 pinout, R5F523E6AGFL#50 application, or R5F523E6AGFL#50 equivalent, this MCU is selected for high-accuracy weigh scales, RTD/thermocouple transmitters, and industrial process controllers requiring simultaneous multi-channel sigma-delta conversion, on-chip excitation, and functional safety support per IEC 60730.

Technical Context

The R5F523E6AGFL#50 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, programmable data rates (1.9–15625 SPS), and simultaneous 50/60 Hz rejection at 10/54 SPS. Each DSAD unit supports up to six differential inputs and includes offset/gain calibration, disconnect detection assist, and external reference voltage input.

Its analog front end includes a 2.5 V voltage reference (±10 ppm/°C drift), bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2), low-side switch (10 Ω max on-resistance), and four excitation current sources with ±0.2% matching and 5 ppm/°C drift matching - all synchronized via the Event Link Controller (ELC) for deterministic timing without CPU intervention.

FAQ

What is the maximum operating frequency and temperature rating of the R5F523E6AGFL#50?

The R5F523E6AGFL#50 operates at a maximum frequency of 32 MHz and is rated for an extended industrial temperature range of –40°C to +105°C (G-grade). This rating is confirmed in Table 1.3 of the datasheet and enables deployment in demanding environments such as motor control cabinets and outdoor process instrumentation where ambient heat exceeds standard commercial limits.

Does the R5F523E6AGFL#50 include integrated excitation current sources, and what are their specifications?

Yes, the R5F523E6AGFL#50 includes four integrated excitation current sources (IEXC0–IEXC3) supporting 50 µA to 1000 µA in programmable steps. They provide ±0.2% current matching and 5 ppm/°C drift matching - critical for ratiometric RTD and strain gauge measurements. These are explicitly documented in Section 1.1 "Outline of Specifications" and Figure 1.3 of the R01DS0330EJ0130 datasheet.

How many 24-bit delta-sigma ADC units does the R5F523E6AGFL#50 support, and what is their effective resolution?

The R5F523E6AGFL#50 supports two independent 24-bit delta-sigma ADC units (DSAD0 and DSAD1), each achieving up to 23-bit effective resolution at 7.6 SPS (gain = 1). This is specified in the "Analog functions" section of the datasheet and validated by the sinc4 filter, offset/gain calibration, and simultaneous 50/60 Hz rejection capabilities.

Is the R5F523E6AGFL#50 CAN-capable, and which CAN standard does it comply with?

Yes, the R5F523E6AGFL#50 includes one RSCAN (CAN) module compliant with ISO 11898-1 for standard and extended frames, supporting bit rates up to 1 Mbps. It provides 16 message boxes and is fully integrated into the MCU's peripheral bus - confirmed in Table 1.1 "Outline of Specifications" and Section 1.4 "Pin Functions" (CRXD0/CTXD0 pins).

What package type and pin count does the R5F523E6AGFL#50 use?

The R5F523E6AGFL#50 uses a 48-pin LFQFP package (PLQP0048KB-B), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This is explicitly stated in Table 1.3 ("List of Products") and Figure 1.4 ("Pin Assignments of the 48-Pin LFQFP") of the R01DS0330EJ0130 datasheet.
