Renesas R5F523E5MGFM#10

Overview

R5F523E5MGFM#10 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and measurement, featuring 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 integrated excitation current sources (50–1000 µA). It operates at up to 32 MHz and supports IEC60730 safety compliance functions.

For engineers reviewing the R5F523E5MGFM#10 datasheet, R5F523E5MGFM#10 pinout, R5F523E5MGFM#10 application, or R5F523E5MGFM#10 equivalent, key selection criteria include its 31.25 kSPS delta-sigma sampling rate, 10-V analog input range, 64-pin LFQFP package with HVAIN support, CAN 2.0B interface, and built-in voltage reference (2.5 V, 8 ppm/°C).

Technical Context

The R5F523E5MGFM#10 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 5-stage CISC Harvard pipeline, and memory protection unit (MPU) - enabling deterministic real-time control in safety-critical sensor nodes. Its analog subsystem integrates a dedicated DSAD module synchronized to PCLKC (≤16 MHz), with fourth- and fifth-order sinc digital filters and simultaneous 50/60 Hz rejection at 10/54 SPS.

Power management includes three low-power modes (sleep, deep sleep, software standby), a low-power timer (LPT) running off sub-clock or IWDT oscillator, and independent voltage detection circuits (LVDAb) with 14-level programmable thresholds. Clock generation supports main (1–20 MHz), sub (32.768 kHz), and PLL (4–8 MHz input) sources, with CAC for frequency accuracy monitoring.

FAQ

What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E5MGFM#10?

The R5F523E5MGFM#10 supports a maximum delta-sigma ADC sampling rate of 31.25 kSPS. This is confirmed in Table 1.3 of the datasheet (R01DS0402EJ0100) under the "Sampling Rate (max.)" column for part number R5F523E5MGFM. The device achieves this rate with fMOD = 4 MHz and supports lower rates down to 3.8 SPS for ultra-high-resolution measurements.

Does R5F523E5MGFM#10 include a real-time clock (RTC) or LCD controller?

No, R5F523E5MGFM#10 does not include an RTC or LCD controller. Per Table 1.2 (page 7), the "Realtime clock" row shows "Not supported" for all 64-pin packages, including PLQP0064KB-C. Similarly, the "LCD controller/driver" row indicates "Not available" for 64-pin variants. These peripherals are only present in 100-pin and 80-pin RX23E-B devices.

What analog input voltage range does R5F523E5MGFM#10 support?

R5F523E5MGFM#10 supports a ±10-V analog input range on its HVAIN pins (HVAIN0–HVAIN3), as specified in Table 1.3 for the "K" and "L" chip versions. The "M" version (used in R5F523E5MGFM#10) retains the same ±10-V HVAIN capability but operates the DSAD at 31.25 kSPS instead of 125 kSPS - distinguishing it from the "K" variant (R5F523E5KGFM#10).

Which communication interfaces are available on R5F523E5MGFM#10?

R5F523E5MGFM#10 includes CAN 2.0B (1 channel, up to 1 Mbps), SCIg (6 channels), RIIC (1 channel, up to 400 kbps), and RSPI (1 channel, up to 16 Mbps). It does not include SCIh or an LCD interface. All interfaces are confirmed in Table 1.2 (page 7) for the 64-pin LFQFP package, and the block diagram (Figure 1.2, page 11) shows their integration with the ELC and peripheral buses.

Is R5F523E5MGFM#10 qualified for extended temperature operation?

Yes, R5F523E5MGFM#10 is a G-version device rated for –40°C to +105°C operation, as indicated by the "G" in the part number per Figure 1.1 (page 10). This is verified in Table 1.3 (page 9), where R5F523E5MGFM appears under the "RX23E-B (G-version)" section with "Operating Temperature: –40 to +105°C" explicitly listed.
