Product details
Overview
R5F523E5BDFL#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensing applications. 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 one CAN channel compliant to ISO 11898-1 at up to 1 Mbps.
For engineers reviewing the R5F523E5BDFL#30 datasheet, R5F523E5BDFL#30 pinout, R5F523E5BDFL#30 application, or R5F523E5BDFL#30 equivalent, key selection criteria include its 125 kSPS delta-sigma sampling rate, ±10-V HVAIN support, 32 MHz CPU operation, integrated excitation current sources (50–1000 µA), and 48-pin LFQFP package with 5-V tolerant I/O.
Technical Context
The R5F523E5BDFL#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU). Its analog subsystem centers on the DSADB module-synchronized to PCLKC (≤16 MHz)-with fourth- and fifth-order sinc digital filters, simultaneous 50/60 Hz rejection, and offset/gain error calibration.
Real-time control is enabled via six-channel MTU2a timers (16-bit), ELC-triggered A/D conversion, and low-power modes including software standby with active LPT. The device supports IEC 60730 Class B compliance through built-in self-test functions for ADC, clock accuracy (CAC), IWDT, and RAM.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E5BDFL#30?
The R5F523E5BDFL#30 supports a maximum delta-sigma ADC sampling rate of 125 kSPS at 3.8 SPS effective resolution. This rate is achievable with modulator clock fMOD = 4 MHz and appropriate sinc filter configuration. Lower data rates (e.g., 10 SPS) enable simultaneous 50/60 Hz rejection for industrial noise immunity.
Does R5F523E5BDFL#30 support ±10-V analog inputs?
No - the R5F523E5BDFL#30 supports up to ±5-V input on HVAIN pins, as indicated by the 'B' suffix in its part number. For ±10-V input capability, select the R5F523E5KDFL#30 ('K' suffix), which shares the same 48-pin LFQFP package and memory configuration.
What communication interfaces are available on R5F523E5BDFL#30?
The R5F523E5BDFL#30 includes one CAN channel (ISO 11898-1, up to 1 Mbps), one I2C interface (up to 400 kbps), one RSPI channel (up to 16 Mbps), and up to five SCI channels (asynchronous/clock-synchronous modes). It does not include an LCD controller or SCIh (LIN) support in this 48-pin variant.
Is the R5F523E5BDFL#30 qualified for IEC 60730 Class B compliance?
Yes - the R5F523E5BDFL#30 includes hardware-assisted self-test features required for IEC 60730 Class B, including ADC disconnect detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT), RAM test support via DOC, and voltage detector functions for analog supply monitoring.
What is the operating voltage range for the analog supply (AVCC0) of R5F523E5BDFL#30?
The R5F523E5BDFL#30 requires AVCC0 = 4.5 V to 5.5 V for full 24-bit ADC performance and specified PGA accuracy. When only the 12-bit S12AD is active, AVCC0 may operate down to 1.8 V, but the 24-bit DSADB module mandates the higher range to ensure reference stability and noise floor integrity.
