Product details
Overview
R5F523E6MDFM#10 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing, featuring a 32-MHz CPU core, 256-KB on-chip flash, 32-KB SRAM, 8-KB data flash, and a 24-bit delta-sigma A/D converter with 31.25 kSPS max sampling rate and ±5-V analog input range. It integrates CAN, SCI, I²C, RSPI, 16-bit D/A, excitation current sources, and voltage reference - deployed in smart sensor nodes and programmable logic controllers.
For engineers reviewing the R5F523E6MDFM#10 datasheet, R5F523E6MDFM#10 pinout, R5F523E6MDFM#10 application, or R5F523E6MDFM#10 equivalent, key selection criteria include its 64-pin LFQFP package (PLQP0064KB-C), –40°C to +85°C operating range (D version), absence of LCD controller, and trade-off between lower delta-sigma sampling rate (31.25 kSPS) versus higher-precision 125-kSPS variants.
Technical Context
The R5F523E6MDFM#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS performance at 32 MHz, and memory protection unit (MPU) for safety-critical firmware. Its analog subsystem centers on a single 24-bit delta-sigma A/D converter (DSADB) with fourth- to fifth-order sinc filtering, programmable gain instrumentation amplifier (×1–×128), and ±5-V HVAIN input capability.
Digital peripherals include one CAN 2.0B channel (1 Mbps), six SCIg interfaces (asynchronous/clock-sync/smart card), one RIICa (I²C/SMBus), one RSPIc (16 Mbps), four-channel DMAC, ELC for interrupt-free inter-module triggering, and low-power modes (sleep, deep sleep, software standby) supported by LPT and IWDT with dedicated 15-kHz oscillator.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E6BDFM#10 | Same 64-pin LFQFP package and D-temp grade, but 125 kSPS delta-sigma ADC (vs. 31.25 kSPS) | Required where higher sampling bandwidth is needed for dynamic sensor signals (e.g., vibration analysis) | Select R5F523E6BDFM#10 if full 125 kSPS capability is essential; otherwise R5F523E6MDFM#10 reduces noise floor at lower rates. |
| R5F523E5MDFM#10 | Same package, temp grade, and delta-sigma spec (31.25 kSPS, ±5 V), but 128 KB flash / 16 KB RAM (vs. 256 KB / 32 KB) | Suitable for cost-sensitive designs with smaller firmware footprint and less runtime data buffering | Choose R5F523E5MDFM#10 when application code size fits within 128 KB and SRAM usage stays below 16 KB. |
Compared with R5F523E6BDFM#10 and R5F523E5MDFM#10, the R5F523E6MDFM#10 uniquely balances mid-range delta-sigma sampling (31.25 kSPS), full 256-KB flash headroom, and industrial temperature rating - making it optimal for calibrated sensor nodes where resolution and firmware flexibility outweigh raw speed or cost minimization.

The R5F523E6MDFM#10 supports a maximum delta-sigma ADC sampling rate of 31.25 kSPS. This is confirmed in Table 1.3 of the R01DS0402EJ0100 datasheet, where the "M" suffix denotes the 31.25 kSPS variant with ±5-V input range. The device does not support the 125 kSPS mode found in "B"/"K"/"L"-suffixed parts.
Does the R5F523E6MDFM#10 include an LCD controller/driver?
No, the R5F523E6MDFM#10 does not include an LCD controller/driver. Per Figure 1.1 (page 10) of the datasheet, the "M" suffix explicitly indicates "LCD driver not included". This distinguishes it from "J" and "L" variants, which integrate LCD functionality for display-oriented applications.
What package type and pin count does the R5F523E6MDFM#10 use?
The R5F523E6MDFM#10 uses the PLQP0064KB-C package: a 64-pin Low-Profile Quad Flat Package measuring 10 × 10 mm with 0.5 mm pitch and an exposed thermal pad. This is verified in Table 1.3 (page 8) and Figure 1.1 (page 10) of the R01DS0402EJ0100 datasheet.
What is the operating temperature range specified for the R5F523E6MDFM#10?
The R5F523E6MDFM#10 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 (page 10) and confirmed in Table 1.3 (page 8) as the "D-version" specification.
How much on-chip flash and SRAM does the R5F523E6MDFM#10 provide?
The R5F523E6MDFM#10 integrates 256 Kbytes of on-chip flash memory and 32 Kbytes of SRAM. These values are explicitly listed in Table 1.3 (page 8) under "ROM Capacity" and "RAM Capacity", and correspond to the "6" digit in the part number per Figure 1.1 (page 10).
