Product details
Overview
R5F523E5SDFL#10 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision industrial sensor signal conditioning, featuring one 24-bit delta-sigma ADC unit, 128 KB on-chip flash, 16 KB SRAM, and integrated programmable gain instrumentation amplifier (PGA) with 30 nVRMS noise at gain=128. It operates from 1.8–5.5 V across –40°C to +85°C and supports IEC60730-compliant self-diagnostic functions for safety-critical measurement systems.
For engineers reviewing the R5F523E5SDFL#10 datasheet, R5F523E5SDFL#10 pinout, R5F523E5SDFL#10 application, or R5F523E5SDFL#10 equivalent, this device delivers calibrated 23-bit effective resolution at 7.6 SPS, rail-to-rail PGA (gain 1–128), on-chip 2.5 V ±10 ppm/°C reference, four excitation current sources (50–1000 µA), and CAN 2.0B interface - all in a 48-pin LFQFP package.
Technical Context
The R5F523E5SDFL#10 implements a dedicated analog front end with two independent 24-bit delta-sigma A/D converters (DSAD0/DSAD1), though only one unit (DSAD0) is enabled per its S-series designation. Its fourth-order sinc filter, simultaneous 50/60 Hz rejection at 10/54 SPS, and offset/gain calibration support high-accuracy thermocouple and RTD measurements without external signal conditioning.
It integrates an RXv2 CPU core running at up to 32 MHz (64 DMIPS), single-precision FPU compliant with IEEE754, memory protection unit (MPU), and event link controller (ELC) enabling low-power synchronized operation of ADC, timers, and communication peripherals without CPU intervention - critical for deterministic sensor data acquisition in industrial PLCs and metering systems.

FAQ
What is the maximum effective resolution achievable with the R5F523E5SDFL#10's delta-sigma ADC?
The R5F523E5SDFL#10 achieves up to 23-bit effective resolution at 7.6 samples per second (SPS) with gain = 1, verified under specified conditions in the datasheet. This performance includes on-chip offset and gain calibration and assumes use of the fourth-order sinc filter and internal 2.5 V reference. Resolution decreases with higher output data rates due to reduced oversampling ratio.
Does the R5F523E5SDFL#10 support IEC60730 Class B compliance out of the box?
The R5F523E5SDFL#10 includes hardware-assisted self-test features required for IEC60730 Class B, including RAM test assistance via DOC, ADC disconnect detection, clock frequency accuracy measurement (CAC), and independent watchdog timer (IWDT) diagnostics. Full compliance requires proper firmware implementation per Renesas' AN1900 application note - the R5F523E5SDFL#10 provides the foundational hardware capabilities.
How many excitation current sources does the R5F523E5SDFL#10 integrate, and what are their key specifications?
The R5F523E5SDFL#10 integrates four independent excitation current sources (IEXC0–IEXC3), each programmable from 50 µA to 1000 µA in discrete steps. They feature ±0.2% current matching and 5 ppm/°C drift matching, enabling high-accuracy 4-wire RTD measurements. The sources support bidirectional operation and can be routed to any AIN pin via the analog multiplexer.
Is CAN functionality available on the R5F523E5SDFL#10, and what protocol versions does it support?
Yes, the R5F523E5SDFL#10 includes one fully integrated CAN module (RSCAN) compliant with ISO11898-1, supporting standard (11-bit) and extended (29-bit) frame formats at up to 1 Mbps. It implements full CAN 2.0B protocol handling, including message buffering (16 mailboxes), automatic retransmission, and error confinement - no external CAN transceiver is required for logic-level interface, though a PHY is needed for bus coupling.
What package type and pin count does the R5F523E5SDFL#10 use, and is it RoHS compliant?
The R5F523E5SDFL#10 uses the PLQP0048KB-B package: a 48-pin Low-Profile Quad Flat Package (LFQFP) with 7 mm × 7 mm body size and 0.5 mm lead pitch. It is RoHS compliant and halogen-free per Renesas' environmental policy. The package includes an exposed thermal pad (non-electrical) and supports standard reflow soldering profiles.
