Product details
Overview
R5F523E5NGFN#10 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensing systems. It integrates a 24-bit delta-sigma ADC with ±5-V input range, 31.25 kSPS max sampling rate, 16-KB SRAM, 128-KB flash, and one CAN channel compliant to ISO11898-1 at up to 1 Mbps - deployed in load cell signal conditioning and smart sensor nodes.
For engineers reviewing the R5F523E5NGFN#10 datasheet, R5F523E5NGFN#10 pinout, R5F523E5NGFN#10 application, or R5F523E5NGFN#10 equivalent, key selection criteria include its 80-pin LFQFP package, –40°C to +85°C operating range (D version), integrated excitation current sources (50–1000 µA), rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), and on-chip voltage reference (2.5 V, 8 ppm/°C).
Technical Context
The R5F523E5NGFN#10 implements the RXv2 CPU core running at up to 32 MHz (64 DMIPS), with IEEE 754-compliant single-precision FPU and memory protection unit (MPU). Its analog subsystem centers on the DSADB module - a 24-bit delta-sigma ADC with fourth- and fifth-order sinc filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and ±10-V-capable HVAIN pins (though this variant supports only ±5 V per datasheet Table 1.3).
It features event-driven operation via ELC, enabling low-power synchronized peripheral triggering without CPU wake-up. Clock management includes PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator; power supply operates from 1.8–5.5 V with three low-power modes and LPT active during software standby.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5JDFN | Same RX23E-B D-version, 80-pin LFQFP, but includes LCD controller (J suffix) and supports 125 kSPS DSAD sampling. | Targeted at HMI-integrated sensor nodes (e.g., portable test equipment with local display); lacks ±5-V HVAIN support in J variant per Table 1.3. | Select R5F523E5JDFN only if LCD driving is required and 125 kSPS sampling is needed - otherwise R5F523E5NGFN#10 offers better analog input range for bridge sensors. |
| ADUCM360BCPZ | Analog Devices 32-bit ARM Cortex-M3 with 24-bit ΣΔ ADC (3.75–2400 SPS), 4-KB SRAM, no CAN, 48-pin LFCSP. | Optimized for ultra-low-power (<380 µA @ 1 kHz) battery-operated sensors; lacks integrated excitation sources, FPU, and industrial comms (CAN/I²C). | Choose ADUCM360BCPZ for sub-1 mA battery life and simple analog-only tasks; R5F523E5NGFN#10 is superior for CAN-connected, computation-heavy, or excitation-dependent industrial nodes. |
Compared with R5F523E5JDFN and ADUCM360BCPZ, the R5F523E5NGFN#10 uniquely balances 31.25 kSPS 24-bit acquisition, ±5-V HVAIN, dual excitation sources, CAN, and 32-MHz RXv2 processing - making it optimal for wired industrial sensor nodes requiring both precision analog and deterministic communication.

The R5F523E5NGFN#10 is a D-version device with an operating ambient temperature range of –40°C to +85°C, as specified in Renesas datasheet R01DS0402EJ0100 Section 1.2 and Figure 1.1. This rating is validated across all electrical specifications and qualifies the part for deployment in standard industrial enclosures without forced cooling.
Which package type does R5F523E5NGFN#10 use?
The R5F523E5NGFN#10 uses an 80-pin LFQFP package designated PLQP0080KB-B - a 12 × 12 mm body with 0.5 mm pitch and exposed thermal pad. This package is RoHS-compliant, supports standard reflow profiles, and is pin-compatible with other RX23E-B 80-pin variants like R5F523E5JDFN and R5F523E5NDFN.
