Renesas R5F523E6JGFN#10

Overview

R5F523E6JGFN#10 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and measurement, featuring a 32-MHz CPU core, 256-KB on-chip flash, 32-KB SRAM, 8-KB data flash, integrated 24-bit delta-sigma ADC (125 kSPS, ±5-V input), rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), and CAN 2.0B interface compliant to ISO 11898-1 at up to 1 Mbps.

For engineers reviewing the R5F523E6JGFN#10 datasheet, R5F523E6JGFN#10 pinout, R5F523E6JGFN#10 application, or R5F523E6JGFN#10 equivalent, this MCU delivers deterministic real-time control with IEEE 754-compliant FPU, memory protection unit (MPU), ELC-triggered peripheral coordination, and IEC 60730-ready self-diagnostic support for safety-critical analog acquisition systems.

Technical Context

The R5F523E6JGFN#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 64 DMIPS performance at 32 MHz. Its analog subsystem centers on a 24-bit delta-sigma ADC with fourth- and fifth-order sinc filtering, ±5-V HVAIN inputs, and programmable excitation current sources (50–1000 µA) for bridge sensor conditioning.

Timing and reliability are managed via independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, low-voltage detection (LVD) across three circuits, and event link controller (ELC) enabling interrupt-free inter-module triggering - critical for synchronized sensor sampling and CAN message transmission without CPU wake-up.

FAQ

What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6JGFN#10?

The R5F523E6JGFN#10 supports a maximum sampling rate of 125 kSPS for its 24-bit delta-sigma ADC. This rate is achievable with modulator clock fMOD = 4 MHz and appropriate sinc filter configuration. At lower data rates (e.g., 3.8 SPS), the device achieves up to 24-bit effective resolution with simultaneous 50/60 Hz rejection - a key capability confirmed in the R01DS0402EJ0100 datasheet Section 1.1.

Does R5F523E6JGFN#10 include an integrated CAN transceiver?

No, the R5F523E6JGFN#10 integrates only the CAN protocol controller (RSCAN module) compliant with ISO 11898-1. An external CAN transceiver (e.g., TJA1042T/3) is required for physical layer signaling. The MCU provides CANH/CANL pins for connection to the transceiver, and its 1 Mbps capability assumes proper external termination and layout per ISO 11898-2 guidelines.

What analog input voltage range does R5F523E6JGFN#10 support on its HVAIN pins?

The R5F523E6JGFN#10 supports a ±5-V input range on its HVAIN0–HVAIN3 pins, as specified in Table 1.3 (List of Products) and confirmed in Section 1.1 "Outline of Specifications". This is distinct from variants with "L" or "K" suffixes that support ±10-V range. The ±5-V range is sufficient for most industrial bridge sensors and RTDs when paired with the on-chip PGA.

Is the LCD controller/driver included in R5F523E6JGFN#10?

Yes, the R5F523E6JGFN#10 includes an integrated LCD controller/driver supporting up to 36 SEG × 8 COM or 40 SEG × 4 COM configurations, as indicated by the "J" in its part number (per Figure 1.1). This matches the "LCD Available" entry in Table 1.3 for R5F523E6JGFN and enables direct driving of segment-based displays without external controllers.

What is the operating temperature grade of R5F523E6JGFN#10?

The R5F523E6JGFN#10 is a G-version device rated for –40°C to +105°C ambient operation, as defined in Table 1.3 and Figure 1.1 ("G: Operating ambient temperature: –40 to +105°C"). This extended temperature range makes it suitable for deployment in harsh industrial environments such as factory automation cabinets and outdoor metering enclosures.
