Product details
Overview
R5F523E6MDFL#50 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing, featuring a 24-bit delta-sigma ADC with 31.25 kSPS max sampling rate, ±5-V analog input range, 256 KB on-chip flash, 32 KB SRAM, and integrated excitation current sources. It operates at up to 32 MHz and supports CAN, SCI, I²C, and RSPI interfaces in a 48-pin LFQFP package for weight scales, process transmitters, and energy meters.
For engineers reviewing the R5F523E6MDFL#50 datasheet, R5F523E6MDFL#50 pinout, R5F523E6MDFL#50 application, or R5F523E6MDFL#50 equivalent, this MCU delivers calibrated 24-bit measurement capability with programmable gain instrumentation amplifiers, on-chip voltage reference (2.5 V, 8 ppm/°C), and IEC60730-compliant self-diagnostic functions for safety-critical analog front-end designs.
Technical Context
The R5F523E6MDFL#50 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 with fourth- to fifth-order sinc digital filters, offset/gain error calibration, 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. The ELC enables interrupt-free inter-module triggering-e.g., MTU timer events initiating DSAD conversions-while the DTC and DMAC offload data movement from CPU execution.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MDFL#50?
The R5F523E6MDFL#50 supports a maximum 24-bit delta-sigma ADC sampling rate of 31.25 kSPS, as defined by its "M" suffix in the part number. This rate applies to the DSADB module with modulator clock at 4 MHz and is confirmed in Table 1.3 of the R01DS0402EJ0100 datasheet. At lower data rates (e.g., 3.8 SPS), effective resolution reaches 24 bits with gain = 1.
Does R5F523E6MDFL#50 include an LCD controller?
No, R5F523E6MDFL#50 does not include an LCD controller. The "M" suffix in the part number explicitly denotes exclusion of the LCD driver, as specified in Figure 1.1 of the R01DS0402EJ0100 datasheet. This distinguishes it from "L" and "N" variants which integrate LCD functionality. The R5F523E6MDFL#50 is optimized for compact sensor interface applications where display driving is handled externally.
What analog input voltage range is supported by R5F523E6MDFL#50?
R5F523E6MDFL#50 supports a ±5-V analog input range on its AIN pins, consistent with its "M" suffix designation per Figure 1.1. It does not support the ±10-V range offered by "K" and "L" variants. This range is enabled by internal rail-to-rail PGA and compatible with AVCC0 = 4.5–5.5 V, ensuring full-scale utilization for industrial sensor signals without external level-shifting.
Which communication interfaces are available on R5F523E6MDFL#50?
R5F523E6MDFL#50 provides CAN (1 channel, ISO 11898-1), 6× SCI (asynchronous/clock-sync/smart card), 1× I²C (400 kbps, SMBus-compatible), and 1× RSPI (16 Mbps). It excludes SCI12 (LIN) and LCD-related interfaces due to its 48-pin LFQFP package constraints, as verified in Table 1.2 of the R01DS0402EJ0100 datasheet.
What is the operating temperature range for R5F523E6MDFL#50?
R5F523E6MDFL#50 is rated for an operating ambient temperature range of –40°C to +85°C, indicated by the "D" suffix in its part number. This industrial-grade specification is validated across all electrical parameters in the R01DS0402EJ0100 datasheet and aligns with common requirements for factory automation, building controls, and outdoor metering equipment.
