Product details
Overview
R5F523E6MGFL#50 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensing applications. It integrates a 24-bit delta-sigma A/D converter with 31.25 kSPS max sampling rate, ±5-V input range, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), on-chip excitation current sources (50–1000 µA), and 256-KB flash/32-KB SRAM - all operating at up to 32 MHz within a –40°C to +85°C ambient range.
For engineers reviewing the R5F523E6MGFL#50 datasheet, R5F523E6MGFL#50 pinout, R5F523E6MGFL#50 application, or R5F523E6MGFL#50 equivalent, this MCU delivers calibrated high-resolution sigma-delta conversion, integrated analog front-end signal conditioning, and CAN/SCI/I²C connectivity - making it suitable for load cell interfaces, precision weigh scales, and industrial process transmitters requiring IEC 60730 compliance support.
Technical Context
The R5F523E6MGFL#50 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, memory protection unit (MPU), and event link controller (ELC) enabling interrupt-free peripheral coordination during low-power sleep modes. Its analog subsystem centers on the DSADB module, synchronized to PCLKC (≤16 MHz), with fourth- and fifth-order sinc digital filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and offset/gain error calibration.
Digital integration includes one CAN channel (ISO 11898-1, up to 1 Mbps), six SCIg channels (asynchronous/clock-sync/smart card), one RIICa (400 kbps SMBus), one RSPIc (16 Mbps), and four-channel DMAC for autonomous data movement - all coordinated via ELC-triggered transfers without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog measurement MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5MGFL#50 | 128 KB flash / 16 KB RAM; identical 24-bit DSAD specs (31.25 kSPS, ±5 V), same package and temp grade | Lower memory capacity suits simpler firmware with minimal calibration tables or no OTA update capability | Select when application firmware fits within 128 KB flash and does not require background data logging or dual-bank updates |
| ADUCM360BCPZ-RL7 | ARM Cortex-M3 core; 24-bit ΣΔ ADC (1.2 kSPS max), integrated 4 mA–20 mA DAC, no CAN, lower clock speed (26 MHz) | Targeted at 4–20 mA loop-powered transmitters; lacks CAN, SCI multiplexing, and ELC autonomy | Prefer for ultra-low-power, loop-powered designs where CAN is unnecessary and 1.2 kSPS suffices for slow-process control |
Compared with R5F523E5MGFL#50, the R5F523E6MGFL#50 provides 128 KB additional flash for complex calibration models and secure boot code, while ADUCM360BCPZ-RL7 trades MCU performance and interface flexibility for integrated loop-driver functionality and lower active power.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MGFL#50?
The R5F523E6MGFL#50 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma A/D converter. This rate is achieved with modulator clock fMOD = 4 MHz and applies to configurations using fourth- or fifth-order sinc filters. Lower rates (e.g., 10 or 54 SPS) enable simultaneous 50/60 Hz rejection for industrial noise immunity.
Does R5F523E6MGFL#50 include an integrated CAN transceiver?
No, the R5F523E6MGFL#50 integrates only the CAN protocol controller (RSCAN module). An external CAN physical-layer transceiver (e.g., SN65HVD23x or TJA1042) must be used on the PCB to drive the CAN bus. The MCU provides CAN_TX and CAN_RX signals compatible with standard ISO 11898-2/3 PHYs.
What analog input voltage range does R5F523E6MGFL#50 support on its HVAIN pins?
The R5F523E6MGFL#50 supports a ±5-V input range on its HVAIN0–HVAIN3 pins. This is confirmed by Table 1.3 in the datasheet, which lists "5 V" under "Analog Input Range (max.)" for part numbers ending in "M", including R5F523E6MGFL#50. The "L" and "K" variants support ±10 V; "M" and "N" variants are limited to ±5 V.
Can R5F523E6MGFL#50 operate from a single 3.3-V supply?
Yes, the R5F523E6MGFL#50 operates from a single 1.8-V to 5.5-V supply on VCC. At 3.3 V, it supports maximum 32-MHz operation per the power supply vs. frequency specification (VCC = 2.7–5.5 V → 32 MHz). AVCC0 must be supplied separately at 4.5–5.5 V for full 12-bit ADC and analog front-end performance.
Is the R5F523E6MGFL#50 pin-compatible with other RX23E-B group members in the same package?
Yes, all RX23E-B MCUs in the PLQP0048KB-B (48-pin LFQFP) package share identical pinouts, including R5F523E6MGFL#50, R5F523E5MGFL#50, and R5F523E6BDFL. Function allocation per pin is consistent across variants; differences are limited to internal configuration (e.g., flash size, DSAD sampling rate, LCD inclusion) and do not affect pin mapping or electrical behavior.
