Product details
Overview
R5F523E5LDFP#10 from Renesas Electronics is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensing and metering systems. It integrates a 24-bit delta-sigma ADC with ±10-V input capability, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), 128 KB on-chip flash, 16 KB SRAM, and a CAN 2.0B interface compliant to ISO 11898-1 at up to 1 Mbps.
For engineers reviewing the R5F523E5LDFP#10 datasheet, R5F523E5LDFP#10 pinout, R5F523E5LDFP#10 application, or R5F523E5LDFP#10 equivalent, this MCU delivers deterministic real-time control, IEC 60730-compliant self-test features, low-drift voltage reference (2.5 V, 8 ppm/°C), and simultaneous 50/60 Hz rejection - critical for energy metering, load cell interfaces, and precision sensor signal conditioning.
Technical Context
The R5F523E5LDFP#10 implements the RXv2 CPU core operating at up to 32 MHz (64 DMIPS), with IEEE 754-compliant single-precision FPU, memory protection unit (MPU), and event link controller (ELC) enabling interrupt-free peripheral coordination during CPU sleep. Its analog subsystem centers on the DSADB module, synchronized to PCLKC (≤16 MHz), with fourth- and fifth-order sinc digital filters and background operation (BGO) for data flash.
It supports three low-power modes (sleep, deep sleep, software standby), with LPT running off sub-clock during standby. Clock generation includes main oscillator (1–20 MHz), PLL (4–8 MHz input), and dedicated IWDT oscillator (15 kHz), while reset architecture includes POR, LVD (3-level configurable), and oscillation stop detection.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5NDFP#10 | Same package and core, but 5-V analog input range (vs. ±10 V), 31.25 kSPS max DSADB sampling rate | Suitable for lower-voltage sensor interfaces (e.g., 0–5 V potentiometers) where ±10 V range and 125 kSPS are unnecessary | Select when cost sensitivity outweighs need for high-voltage input or fast sampling; retains identical pinout and firmware compatibility |
| R5F523E5LDBS#10 | Same analog specs (±10 V, 125 kSPS), but 100-pin TFBGA (5.5 × 5.5 mm) vs. LFQFP; no LCD driver | Targeted at space-constrained PCBs where fine-pitch BGA assembly is available and display interface is unused | Choose for ultra-compact designs with BGA capability; requires different layout and rework process versus QFP |
Compared with R5F523E5NDFP#10, the R5F523E5LDFP#10 provides higher analog input range and faster sampling for demanding metrology, while versus R5F523E5LDBS#10 it offers easier assembly and thermal management via QFP packaging - critical for industrial environments with vibration and thermal cycling.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in the R5F523E5LDFP#10?
The R5F523E5LDFP#10 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC (DSADB). This rate is achievable with modulator clock fMOD = 4 MHz and appropriate digital filter configuration (e.g., sinc1 or reduced-order sinc filters). At lower rates like 10 SPS or 54 SPS, the device enables simultaneous 50 Hz/60 Hz rejection for energy metering compliance.
Does the R5F523E5LDFP#10 include an integrated CAN transceiver?
No, the R5F523E5LDFP#10 integrates a CAN 2.0B controller (RSCAN module) but does not include a physical-layer transceiver. External CAN transceivers (e.g., SN65HVD23x, TJA1042) must be used on the PCB to interface with the CAN bus. The R5F523E5LDFP#10 provides CAN_TX and CAN_RX signals compatible with standard ISO 11898-2/3 transceivers.
What analog input voltage range does the R5F523E5LDFP#10 support on its HVAIN pins?
The R5F523E5LDFP#10 supports a ±10-V input voltage range on its HVAIN0–HVAIN3 pins, enabled by its high-voltage analog input circuitry. This allows direct connection to industrial sensors such as strain gauges, shunt-based current monitors, and bipolar transducer outputs without external level-shifting or attenuation networks.
Is the R5F523E5LDFP#10 pin-compatible with other members of the RX23E-B Group?
Within the same package type (e.g., PLQP0100KB-B), the R5F523E5LDFP#10 is pin-compatible with other 100-pin LFQFP variants like R5F523E5NDFP#10 and R5F523E6LDFP#10. Differences lie in flash/RAM size, analog range, and sampling rate - all supported by identical pin assignments and electrical characteristics per the Renesas RX23E-B hardware manual.
What is the operating temperature range specified for the R5F523E5LDFP#10?
The R5F523E5LDFP#10 is rated for an operating ambient temperature range of –40°C to +85°C (D version). This specification applies to all functional blocks including the 24-bit delta-sigma ADC, PGA, voltage reference, and CPU core, and is validated per JEDEC JESD22-A104 reliability testing standards.
