Product details
Overview
R5F523E6JDFN#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and measurement, 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 supporting 36-segment × 8-common drive. It operates across –40°C to +85°C and integrates CAN, SCI, I²C, RSPI, and precision analog front-end functions including programmable-gain instrumentation amplifier, excitation current sources, and voltage reference.
For engineers reviewing the R5F523E6JDFN#30 datasheet, R5F523E6JDFN#30 pinout, R5F523E6JDFN#30 application, or R5F523E6JDFN#30 equivalent, key selection criteria include its 80-pin LFQFP package with LCD driver support, 125-kSPS delta-sigma ADC performance at ±5-V input, real-time clock with calendar mode, and integrated CAN 2.0B compliance up to 1 Mbps - all critical for smart sensor nodes, industrial process controllers, and energy metering systems requiring embedded signal conditioning and display capability.
Technical Context
The R5F523E6JDFN#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, delivering 64 DMIPS at 32 MHz and supporting IEEE 754-compliant single-precision FPU, DSP instructions (multiply-accumulate/subtract), and memory protection unit (MPU). Its analog subsystem centers on the DSADB module synchronized to PCLKC (≤16 MHz), with configurable sinc filters and PGA gain settings (×1–×128) enabling high-resolution weight scale or strain gauge readouts.
Real-time control is enabled by ELC-driven event chaining between MTU2a timers and ADC conversion triggers, while low-power operation leverages three sleep modes and LPT running off sub-clock oscillator during software standby. The device supports IEC 60730 Class B compliance via hardware-assisted self-test for ADC, IWDT, clock accuracy (CAC), and RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E6JDFP | Same RX23E-B core, identical peripherals and ADC specs, but in 100-pin LFQFP (PLQP0100KB-B) with larger pin count and LCD support. | Offers 10 additional GPIOs, full 6-channel SCI, and 40×4 LCD drive - suited for designs needing more serial interfaces or larger display. | Select R5F523E6JDFP when board layout allows larger package and requires extra I/O or enhanced LCD capability beyond 36×8. |
| R5F523E5JDFN | Same 80-pin LFQFP package and LCD support, but with 128-KB flash, 16-KB SRAM, and identical 24-bit ADC (125 kSPS, ±5-V). | Lower memory capacity limits firmware complexity; suitable for cost-sensitive applications with simpler feature sets. | Choose R5F523E5JDFN where application firmware fits within 128 KB and no future feature expansion is planned - reduces cost without sacrificing analog performance. |
Compared with R5F523E6JDFN#30, R5F523E6JDFP offers higher I/O density and extended LCD drive at the cost of larger footprint, while R5F523E5JDFN trades flash/SRAM capacity for lower unit cost - both retain identical analog precision and real-time capabilities essential for industrial sensing.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6JDFN#30?
The R5F523E6JDFN#30 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC (DSADB) when operating with fMOD = 4 MHz. This rate is achievable with reduced digital filter order and is specified for ±5-V analog input range - making it suitable for high-speed sensor acquisition such as dynamic strain or fast-response thermocouple measurements.
Does R5F523E6JDFN#30 include an integrated LCD controller, and what display configurations does it support?
Yes, R5F523E6JDFN#30 includes an integrated LCD controller/driver (LCDC) supporting 36-segment × 8-common multiplexed displays. It implements internal voltage boosting and supports capacitor-split or external resistor-divider bias methods. This enables direct drive of alphanumeric LCD modules in portable instruments and panel meters without external display drivers.
What analog input voltage range is supported by the HVAIN pins on R5F523E6JDFN#30?
The R5F523E6JDFN#30 features four HVAIN pins rated for ±10-V input, but the specific variant R5F523E6JDFN#30 is configured for ±5-V analog input range as indicated by the 'J' suffix in its part number. This configuration balances high-voltage tolerance with optimal noise performance for industrial sensor interfaces like 4–20 mA receivers and bridge amplifiers.
Can R5F523E6JDFN#30 operate with a single power supply, and what is the valid voltage range?
Yes, R5F523E6JDFN#30 operates from a single VCC supply ranging from 1.8 V to 5.5 V, with corresponding maximum CPU frequencies of 8 MHz (1.8–2.4 V), 16 MHz (2.4–2.7 V), and 32 MHz (2.7–5.5 V). However, the analog section (AVCC0) requires 4.5–5.5 V for full 12-bit ADC and analog front-end performance - necessitating either a dedicated analog rail or LDO regulation.
Is R5F523E6JDFN#30 qualified for IEC 60730 Class B compliance, and which hardware features enable this?
Yes, R5F523E6JDFN#30 includes hardware-assisted features for IEC 60730 Class B compliance, including ADC self-calibration (offset/gain), independent watchdog timer (IWDT) with dedicated oscillator, clock frequency accuracy measurement circuit (CAC), RAM test assistance via data operation circuit (DOC), and analog input disconnect detection - all documented in Renesas' functional safety manual R01US0402EJ0100.
