Product details
Overview
R5F523E6KDFM#10 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 ADC with ±10-V input capability, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), 256 KB on-chip flash, 32 KB SRAM, and CAN 2.0B interface - all operating at up to 32 MHz. Designed for weight scales, pressure transmitters, and strain-gauge-based condition monitoring systems.
For engineers reviewing the R5F523E6KDFM#10 datasheet, R5F523E6KDFM#10 pinout, R5F523E6KDFM#10 application, or R5F523E6KDFM#10 equivalent, key selection criteria include its 10-V analog input range, 125 kSPS delta-sigma sampling rate, integrated excitation current sources (50–1000 µA), low-drift voltage reference (2.5 V, 8 ppm/°C), and IEC60730-compliant self-test functions for safety-critical sensor nodes.
Technical Context
The R5F523E6KDFM#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) for deterministic real-time control. Its analog subsystem centers on the DSADB module: a 24-bit delta-sigma ADC with fourth- to fifth-order sinc filtering, simultaneous 50/60 Hz rejection at 10/54 SPS, and ±10-V HVAIN inputs enabled by internal low-side switches (10 Ω).
Clock management includes PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator; peripheral clock domains (PCLKA–PCLKD) are independently configurable - PCLKC drives DSADB at up to 16 MHz, enabling full 125 kSPS operation. The ELC enables event-triggered ADC conversions without CPU intervention, critical for low-power wake-on-event sensor firmware.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6KDFM#10?
The R5F523E6KDFM#10 supports a maximum delta-sigma ADC sampling rate of 125 kSPS at 24-bit resolution using a 4 MHz modulator clock. This rate is achievable with sinc4 filtering and applies specifically to the DSADB module, which is fully operational in the R5F523E6KDFM#10's 64-pin LFQFP package configuration.
Does R5F523E6KDFM#10 include an LCD controller?
No, the R5F523E6KDFM#10 does not include an LCD controller. Per Renesas' part numbering scheme, the "K" suffix indicates a 10-V analog input variant *without* LCD driver functionality. This distinguishes it from "L"-suffix parts (e.g., R5F523E6LDFP) that integrate LCD support.
What analog input voltage range does R5F523E6KDFM#10 support?
The R5F523E6KDFM#10 supports a ±10-V analog input range on its HVAIN0–HVAIN3 pins. This is enabled by internal high-voltage input circuitry and low-side switches (10 Ω), allowing direct connection of industrial bridge sensors without external signal conditioning.
Is R5F523E6KDFM#10 qualified for IEC60730 functional safety compliance?
Yes, the R5F523E6KDFM#10 includes hardware-assisted features for IEC60730 Class B compliance: self-test for RAM (via DOC), A/D converter calibration and disconnect detection, clock frequency accuracy measurement (CAC), and independent watchdog timer (IWDT) diagnostics - all documented in the RX23E-B hardware manual.
What is the operating temperature range of R5F523E6KDFM#10?
The R5F523E6KDFM#10 is rated for an operating ambient temperature range of –40°C to +85°C (D-version). This is confirmed by Renesas' official product table (R01DS0402EJ0100, Page 8) and applies to all package variants including the PLQP0064KB-C 64-pin LFQFP used in this part number.
