It operates at up to 32 MHz and supports CAN, SCI, I²C, and RSPI interfaces.

For engineers reviewing the R5F523E6MDFL#10 datasheet, R5F523E6MDFL#10 pinout, R5F523E6MDFL#10 application, or R5F523E6MDFL#10 equivalent, this MCU delivers calibrated 24-bit sigma-delta conversion, on-chip excitation current sources (50–1000 µA), low-drift voltage reference (2.5 V, 8 ppm/°C), and real-time clock functionality - all in a 48-pin LFQFP package rated for –40°C to +85°C operation.

Technical Context

The R5F523E6MDFL#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS performance at 32 MHz, and memory protection unit (MPU) for safety-critical firmware. Its analog subsystem centers on the DSADB module, synchronized to PCLKC (≤16 MHz), with fourth- or fifth-order sinc filtering, simultaneous 50/60 Hz rejection at 10/54 SPS, and PGA gain settings from ×1 to ×128.

Digital integration includes ELC-driven event-triggered A/D conversion, four-channel DMAC, DTC with chain transfer, and RSCAN CAN controller compliant with ISO 11898-1 (1 Mbps). Power management supports three low-power modes, LPT operation during software standby, and voltage detection circuits with 14-level programmability on LVDAb1.

FAQ

What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MDFL#10?

The R5F523E6MDFL#10 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma ADC. This rate is achieved with the modulator clock set to 4 MHz and appropriate sinc filter configuration. At lower data rates (e.g., 3.8 SPS), the device achieves 24-bit effective resolution with gain = 1, while maintaining simultaneous 50/60 Hz rejection at 10/54 SPS.

Does R5F523E6MDFL#10 include an integrated CAN controller?

Yes, the R5F523E6MDFL#10 integrates a fully compliant ISO 11898-1 CAN module (RSCAN) supporting standard and extended frames at up to 1 Mbps. It includes 16 message boxes, automatic retransmission, and error confinement - eliminating the need for an external CAN transceiver PHY in many industrial network designs.

What analog input voltage range does R5F523E6MDFL#10 support on its HVAIN pins?

The R5F523E6MDFL#10 supports a ±5-V input range on its HVAIN0–HVAIN3 pins. This is confirmed by the part number suffix "M", which denotes the 31.25 kSPS / ±5-V variant per Renesas' product coding in Table 1.3 and Figure 1.1 of R01DS0402EJ0100 Rev.1.00.

Is the R5F523E6MDFL#10 compatible with the Renesas E1 emulator for debugging?

Yes, the R5F523E6MDFL#10 supports on-chip debugging via the FINE interface and is fully compatible with the Renesas E1 emulator. The device includes dedicated debug pins and adheres to the RX family's debugging architecture, enabling full SWD-style breakpoints, watchpoints, and real-time variable inspection during development.

What is the operating temperature range specified for R5F523E6MDFL#10?

The R5F523E6MDFL#10 is rated for an operating ambient temperature range of –40°C to +85°C. This is indicated by the "D" suffix in the part number per Figure 1.1, and confirmed in Table 1.3 where all "MDFL" variants are listed under the RX23E-B (D-version) column with "–40 to +85°C".
