Product details
Overview
R5F523E6NGFN#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 sampling rate and ±5-V analog input range. It integrates CAN, SCI, I²C, RSPI, 16-bit D/A, excitation current sources, and low-power operation down to software standby mode - deployed in smart sensor nodes and programmable logic controllers.
For engineers reviewing the R5F523E6NGFN#10 datasheet, R5F523E6NGFN#10 pinout, R5F523E6NGFN#10 application, or R5F523E6NGFN#10 equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options - all grounded in Renesas R01DS0402EJ0100 Rev.1.00 specifications for the RX23E-B Group G-version 80-pin LFQFP variant.
Technical Context
The R5F523E6NGFN#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS at 32 MHz, and memory protection unit (MPU) for safety-critical firmware execution. 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 - calibrated for <4 nV/°C offset drift and 1 ppm/°C gain drift.
Digital integration includes one CAN channel (ISO 11898-1, up to 1 Mbps), six SCIg interfaces (asynchronous/clock-synchronous/smart card), one RIICa I²C bus interface (400 kbps), one RSPIc (16 Mbps), and event-driven peripheral coordination via ELC - enabling deterministic low-latency response without CPU wake-up in deep sleep modes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5NGFN#10 | 128 KB flash / 16 KB RAM / same 31.25 kSPS DSADB and ±5-V HVAIN - lower memory capacity, identical analog and peripheral set | Suitable for cost-sensitive designs with smaller firmware footprint and fewer runtime variables | Select when full 256 KB flash is unnecessary and BOM cost reduction is prioritized over future firmware scalability |
| R5F523E6JGFN#10 | Same 256 KB flash / 32 KB RAM / 31.25 kSPS DSADB but adds LCD controller (40 SEG × 4 COM) - no HVAIN support | Targeted at human-interface devices (e.g., panel meters) requiring local display instead of high-voltage analog inputs | Choose only if integrated LCD driving is required and ±5-V sensor interfacing is not needed - incompatible for HVAIN-dependent applications |
Compared with R5F523E6NGFN#10, R5F523E5NGFN#10 offers identical analog performance at reduced memory cost, while R5F523E6JGFN#10 trades HVAIN capability for LCD integration - making R5F523E6NGFN#10 the optimal choice for high-accuracy sensor acquisition where ±5-V input range and 256 KB code space are essential.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6NGFN#10?
The R5F523E6NGFN#10 features a 24-bit delta-sigma A/D converter (DSADB) with a maximum sampling rate of 31.25 kSPS. This rate is achieved with modulator clock fMOD = 4 MHz and appropriate sinc filter configuration - supporting high-resolution measurements for strain gauges, load cells, and RTDs in industrial automation systems.
Does R5F523E6NGFN#10 support ±10-V analog inputs?
No, R5F523E6NGFN#10 does not support ±10-V analog inputs. Per Renesas R01DS0402EJ0100 Rev.1.00 Table 1.3, the 'N' suffix denotes a ±5-V analog input range. The ±10-V capability is reserved for 'K' and 'L' variants (e.g., R5F523E6KGFN#10). R5F523E6NGFN#10 uses HVAIN pins rated for ±5 V maximum.
What package type and pin count does R5F523E6NGFN#10 use?
R5F523E6NGFN#10 uses the PLQP0080KB-B package: an 80-pin Low-Profile Quad Flat Package measuring 12 mm × 12 mm with 0.5 mm pitch. This LFQFP variant is RoHS-compliant and designed for reflow soldering in high-volume industrial PCB assembly.
Is the R5F523E6NGFN#10 qualified for extended temperature operation?
Yes, R5F523E6NGFN#10 is the G-version part, qualified for operation from –40°C to +105°C ambient temperature. This extended range meets industrial requirements for deployment in control cabinets, motor drives, and outdoor metering equipment without active thermal management.
Does R5F523E6NGFN#10 include an integrated LCD controller?
No, R5F523E6NGFN#10 does not include an LCD controller. The 'N' suffix in the part number indicates inclusion of the 24-bit delta-sigma ADC with 31.25 kSPS and ±5-V input range, but omission of the LCD driver. LCD functionality is present only in 'J' and 'L' variants (e.g., R5F523E6JGFN#10).
