Product details
Overview
R5F523E6MDFM#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and measurement applications, featuring a 32-MHz CPU core, 256-KB on-chip flash, 32-KB SRAM, 8-KB data flash, integrated 24-bit delta-sigma ADC with 31.25 kSPS max sampling rate and ±5-V analog input range, and CAN 2.0B interface compliant to ISO11898-1 at up to 1 Mbps.
For engineers reviewing the R5F523E6MDFM#30 datasheet, R5F523E6MDFM#30 pinout, R5F523E6MDFM#30 application, or R5F523E6MDFM#30 equivalent, this MCU delivers calibrated low-drift analog front-end performance, real-time control via ELC-linked peripherals, IEC60730 safety support, and deterministic timing for sensor signal conditioning in programmable logic controllers, weigh scales, and industrial transmitters.
Technical Context
The R5F523E6MDFM#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, supporting 64 DMIPS at 32 MHz and IEEE 754-compliant single-precision FPU. Its analog subsystem centers on a 24-bit delta-sigma ADC (DSADB) with fourth- and fifth-order sinc filters, programmable gain instrumentation amplifier (gain = 1–128), ±5-V HVAIN inputs, and simultaneous 50/60 Hz rejection at 10/54 SPS.
Clock management includes PLL, main/sub oscillators, and CAC for frequency accuracy monitoring; power management supports three low-power modes with LPT operation during software standby; and event-driven operation is enabled by ELC, allowing peripheral chaining without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E6BDFM#30 | Same package and memory (256 KB flash/32 KB RAM), but 125 kSPS DSAD sampling rate and ±5-V input - higher-speed variant without LCD driver. | Better suited for dynamic sensor applications (e.g., vibration monitoring) requiring >31 kSPS sustained throughput. | Select R5F523E6BDFM#30 when sampling rate >31.25 kSPS is mandatory; otherwise R5F523E6MDFM#30 offers optimal power/performance trade-off for static measurements. |
| R5F523E5MDFM#30 | 128 KB flash / 16 KB RAM / same 31.25 kSPS DSAD and ±5-V input - lower memory capacity, identical analog performance and package. | Ideal for cost-sensitive designs where firmware footprint remains under 128 KB and no future feature expansion is planned. | Choose R5F523E5MDFM#30 for volume production where memory headroom is not required - saves ~15% unit cost with no analog performance penalty. |
Compared with R5F523E6BDFM#30 and R5F523E5MDFM#30, the R5F523E6MDFM#30 uniquely balances 256-KB code space for safety-certified firmware with 31.25-kSPS precision ADC performance in a compact 64-pin LFQFP - making it the optimal choice for Class 0.1 industrial transmitters where memory scalability and measurement stability are both critical.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MDFM#30?
The R5F523E6MDFM#30 features a 24-bit delta-sigma ADC (DSADB) with a maximum sampling rate of 31.25 kSPS. This rate is achieved at modulator clock = 4 MHz and applies to configurations using fourth-order sinc filtering. At lower data rates (e.g., 3.8 SPS), effective resolution reaches 24 bits with gain = 1.
Does R5F523E6MDFM#30 support IEC60730 Class B compliance out of the box?
The R5F523E6MDFM#30 includes hardware-assisted self-test functions for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM (via DOC), and analog input disconnect detection - enabling streamlined IEC60730 Class B certification when combined with appropriate software routines defined in Renesas Application Note R01AN3813.
What analog input voltage range does R5F523E6MDFM#30 support on its HVAIN pins?
The R5F523E6MDFM#30 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 number R5F523E6MDFM. The device does not support ±10-V input - that capability is reserved for variants with "K" or "L" suffixes (e.g., R5F523E6KDFM).
Is the R5F523E6MDFM#30 pin-compatible with other RX23E-B group MCUs in the same package?
Yes - all RX23E-B group devices in the PLQP0064KB-C (64-pin LFQFP) package share identical pinouts, including R5F523E6MDFM#30, R5F523E6BDFM#30, and R5F523E5MDFM#30. Function allocation per pin is consistent across variants; differences are limited to internal configuration (e.g., DSAD sampling rate, flash size) and do not affect PCB layout.
What is the operating temperature range specified for R5F523E6MDFM#30?
The R5F523E6MDFM#30 is rated for an operating ambient temperature range of –40°C to +85°C. This is indicated by the "D" suffix in the part number per Figure 1.1 of the datasheet, and confirmed in Table 1.3 under "Operating Temperature" for all "D-version" entries including R5F523E6MDFM.
