Product details
Overview
R5F523E5LDFP#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensor nodes 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), on-chip excitation current sources (50–1000 µA), and 128 KB flash/16 KB SRAM - all operating at up to 32 MHz with IEC60730 safety support.
For engineers reviewing the R5F523E5LDFP#30 datasheet, R5F523E5LDFP#30 pinout, R5F523E5LDFP#30 application, or R5F523E5LDFP#30 equivalent, this MCU delivers deterministic real-time control, low-drift analog front-end performance (11 nVRMS, 4 nV/°C offset drift), CAN 2.0B interface, and hardware-accelerated self-test functions critical for Class B compliance in smart transmitters and energy monitoring devices.
Technical Context
The R5F523E5LDFP#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) - enabling deterministic execution for safety-critical firmware. Its analog subsystem centers on the DSADB module synchronized to PCLKC (≤16 MHz), with configurable sinc filters and simultaneous 50/60 Hz rejection at 10/54 SPS.
Digital integration includes ELC-driven event-triggered operation (e.g., ADC start via MTU pulse), four-channel DMAC for zero-CPU-overhead data movement, and dual-clock domain architecture: ICLK (CPU/system bus, ≤32 MHz), PCLKA (MTU2a), PCLKC (DSAD), and PCLKD (S12AD). The device supports three low-power modes with LPT active during software standby.

The following parts are listed as comparable options for similar high-precision analog microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E5NDFP#30 | Same package and core, but 5-V analog input range (vs. ±10 V), 31.25 kSPS DSAD max sampling rate | Suitable for lower-voltage sensor interfaces (e.g., 0–5 V thermocouples) where full ±10 V range is unnecessary | Select when cost sensitivity outweighs need for high-voltage direct sensing; retains identical pinout and firmware compatibility |
| R5F523E5LDBS#30 | Same analog specs (±10 V, 125 kSPS), but 100-pin TFBGA (5.5 × 5.5 mm) vs. LFQFP (14 × 14 mm) | Targeted for space-constrained PCBs where footprint reduction justifies BGA assembly complexity | Choose for miniaturized designs requiring same analog performance; requires rework of layout and thermal management |

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E5LDFP#30?
The R5F523E5LDFP#30 supports a maximum DSAD sampling rate of 125 kSPS at reduced resolution, with 24-bit effective resolution achievable at 3.8 SPS. This trade-off enables high-speed transient capture or ultra-precise static measurement depending on application needs - both fully supported by the on-chip sinc filter configurations and ELC-triggered acquisition in the R5F523E5LDFP#30.
Does R5F523E5LDFP#30 include hardware support for IEC60730 Class B compliance?
Yes, the R5F523E5LDFP#30 integrates dedicated hardware for IEC60730 Class B: memory protection unit (MPU), clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with oscillator self-test, data operation circuit (DOC) for RAM testing, and analog subsystem diagnostics including DSAD input disconnect detection - all documented in the R5F523E5LDFP#30 functional safety manual.
What analog input voltage range does R5F523E5LDFP#30 support on its HVAIN pins?
The R5F523E5LDFP#30 supports a ±10-V input range on its HVAIN0–HVAIN3 pins, enabling direct connection to high-output industrial sensors like load cells and strain gauges without external level-shifting circuitry. This specification is confirmed in Table 1.3 of the R5F523E5LDFP#30 datasheet and applies exclusively to 'L' and 'K' variant part numbers.
Can R5F523E5LDFP#30 operate with a single power supply rail?
Yes, the R5F523E5LDFP#30 operates from a single 1.8-V to 5.5-V VCC supply, with AVCC0 requiring 4.5–5.5 V only when the 12-bit S12AD is active. Its low-power design includes three operational modes (sleep, deep sleep, software standby) and a low-power timer (LPT) that runs during standby - all enabled without auxiliary supplies, simplifying power architecture in the R5F523E5LDFP#30.
Is the R5F523E5LDFP#30 pin-compatible with other RX23E-B group MCUs in the same package?
Yes, all 100-pin LFQFP variants in the RX23E-B group - including R5F523E5LDFP#30, R5F523E5NDFP#30, and R5F523E6LDFP#30 - share identical pinouts and electrical characteristics per package type (PLQP0100KB-B). Firmware portability is further ensured by consistent peripheral register mapping and ELC/DMAC/DTC architecture across the R5F523E5LDFP#30 family.
