Product details
Overview
R5F523E6JGFN#50 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and control, 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 125-kSPS max sampling rate and ±5-V analog input range, and built-in LCD controller. It operates across –40°C to +105°C and supports CAN, SCI, I²C, RSPI, and ELC-based event-driven operation.
For engineers reviewing the R5F523E6JGFN#50 datasheet, R5F523E6JGFN#50 pinout, R5F523E6JGFN#50 application, or R5F523E6JGFN#50 equivalent, this MCU delivers deterministic real-time performance for precision measurement systems requiring simultaneous high-resolution analog acquisition, low-latency communication, and embedded signal processing without external ADCs or display drivers.
Technical Context
The R5F523E6JGFN#50 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, 64 DMIPS @ 32 MHz, single-precision IEEE754 FPU, and memory protection unit (MPU). Its analog subsystem centers on an 8-channel 24-bit delta-sigma ADC with programmable gain instrumentation amplifier (gain = 1–128), fourth- and fifth-order sinc digital filters, and ±5-V HVAIN inputs-configured for direct connection to load cells and RTDs.
Timing and system control are managed via dedicated clocks: PCLKC up to 16 MHz for DSAD operation, PCLKD up to 32 MHz for S12AD, and independent IWDT-dedicated 15-kHz oscillator. The ELC enables autonomous peripheral chaining-including MTU-triggered ADC conversion and DTC-assisted data movement-without CPU intervention during sleep modes.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6JGFN#50?
The R5F523E6JGFN#50 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC. This rate is achievable with reduced digital filter order and is specified under fMOD = 4 MHz modulator clock conditions. At lower rates (e.g., 10 SPS), the device enables simultaneous 50/60 Hz rejection using configurable sinc filters - a key capability for precision AC power monitoring applications.
Does R5F523E6JGFN#50 include an integrated LCD controller, and what display configurations does it support?
Yes, the R5F523E6JGFN#50 includes an integrated LCD controller supporting 36-segment × 8-common (36 SEG × 8 COM) displays. It uses internal voltage boosting and supports capacitor-split or external resistor-divider bias methods. This eliminates external LCD driver ICs and simplifies design for panel meters, industrial HMIs, and portable test equipment requiring alphanumeric readouts.
What analog input voltage range is supported by the HVAIN pins on R5F523E6JGFN#50?
The HVAIN pins on R5F523E6JGFN#50 support a ±5-V input range. This is confirmed by Table 1.3 in the datasheet, which lists "5 V" under "Analog Input Range (max.)" for part numbers ending in "J", including R5F523E6JGFN#50. The ±5-V tolerance enables direct interfacing with industrial sensors such as strain gauges, pressure transducers, and isolated 4–20 mA receivers without external level-shifting circuitry.
How many communication interfaces does R5F523E6JGFN#50 provide, and which protocols are supported?
The R5F523E6JGFN#50 provides one CAN channel (ISO11898-1, up to 1 Mbps), six SCI channels (asynchronous, clock-synchronous, smart card), one I²C bus interface (up to 400 kbps, SMBus-compatible), and one RSPI channel (up to 16 Mbps). These interfaces support industrial networking, sensor communication, display control, and firmware updates - all concurrently operable due to independent clock domains and ELC-assisted synchronization.
What is the operating temperature range for R5F523E6JGFN#50, and how is it indicated in the part number?
The R5F523E6JGFN#50 is rated for –40°C to +105°C operation, denoted by the "G" in the part number (R5F523E6JGFN#50). Per Figure 1.1 of the datasheet, "G" specifies the extended industrial temperature grade, distinguishing it from "D"-grade variants rated to +85°C. This makes R5F523E6JGFN#50 suitable for deployment in high-ambient environments like electrical substations and factory-floor controllers.
