Product details
Overview
R5F523E6MDFL#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 31.25 kSPS max sampling rate, ±5-V input range, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), on-chip excitation current sources (50–1000 µA), and a low-drift 2.5-V voltage reference (8 ppm/°C). It operates at up to 32 MHz and supports IEC60730 safety compliance functions.
For engineers reviewing the R5F523E6MDFL#30 datasheet, R5F523E6MDFL#30 pinout, R5F523E6MDFL#30 application, or R5F523E6MDFL#30 equivalent, key selection criteria include its 48-pin LFQFP package, 256-KB flash / 32-KB SRAM / 8-KB data flash memory configuration, integrated CAN interface (ISO11898-1, up to 1 Mbps), and support for simultaneous 50/60 Hz rejection at 10/54 SPS - critical for precision weight scale and energy metering designs.
Technical Context
The R5F523E6MDFL#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) for secure embedded execution. Its analog subsystem centers on the DSADB module, synchronized to PCLKC (≤16 MHz), with configurable sinc filters (4th/5th-order), offset/gain calibration, and disconnect detection for HVAIN pins.
Digital peripherals include a 1-channel CAN controller (RSCAN), 6-channel SCIg (asynchronous/clock-sync/smart card), 1-channel RIIC (I²C/SMBus), and RSPI (up to 16 Mbps), all coordinated via the Event Link Controller (ELC) to enable CPU-free inter-module triggering - essential for deterministic sensor acquisition without interrupt latency.

FAQ
What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MDFL#30?
The R5F523E6MDFL#30 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma ADC (DSADB). This rate is achieved with modulator clock fMOD = 4 MHz and appropriate sinc filter configuration. At lower data rates (e.g., 10 or 54 SPS), the device delivers simultaneous 50/60 Hz rejection - a key capability for industrial AC-line-noise immunity. The R5F523E6MDFL#30 does not support the 125 kSPS mode found in 'B'/'J'/'K'/'L' variants.
Does R5F523E6MDFL#30 include an integrated CAN controller?
Yes, the R5F523E6MDFL#30 integrates one channel of the RSCAN CAN module compliant with ISO11898-1, supporting standard and extended frames at up to 1 Mbps. It includes 16 message boxes, programmable acceptance filtering, and automatic retransmission. The CANH and CANL pins are assigned to dedicated package pins in the 48-pin LFQFP (PLQP0048KB-B), and the R5F523E6MDFL#30 requires no external transceiver for basic bus connection - though an external PHY is needed for robust industrial deployment.
What analog input voltage range does R5F523E6MDFL#30 support?
The R5F523E6MDFL#30 supports a ±5-V differential input range on its HVAIN pins (HVAIN0–HVAIN3), as indicated by the 'M' suffix in its part number per Renesas' naming convention. It does not support the ±10-V range offered by 'K'/'L' variants. This ±5-V range is fully compatible with common industrial sensors including 350-Ω strain gauges, 4–20 mA loop receivers, and RTD front-ends when used with the integrated excitation current sources and rail-to-rail PGA.
Is the R5F523E6MDFL#30 pin-compatible with other RX23E-B group MCUs in the same package?
Yes, the R5F523E6MDFL#30 is pin-compatible with all other RX23E-B group devices in the 48-pin LFQFP (PLQP0048KB-B) package, including R5F523E5MDFL#30 and R5F523E6BDFL#30. Pin functions, power domains, and peripheral mappings are identical across these variants. Firmware portability is supported at the HAL level, though users must verify flash size, RAM allocation, and enabled peripherals (e.g., RTC is not available in 48-pin variants) when migrating between R5F523E6MDFL#30 and other members.
What is the operating temperature grade of R5F523E6MDFL#30?
The R5F523E6MDFL#30 is rated for industrial operation from –40°C to +85°C, denoted by the 'D' suffix in its part number. This grade meets JEDEC JESD47 reliability requirements and is validated for continuous operation across the full range with no derating. It is not qualified for the extended –40°C to +105°C ('G' grade) range used in under-hood automotive or high-ambient industrial enclosures.
