Renesas R5F523E5MGFL#30

Overview

R5F523E5MGFL#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing, featuring a 24-bit delta-sigma ADC with ±10-V input capability, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), 128-KB flash, 16-KB SRAM, and integrated excitation current sources (50–1000 µA). It operates at up to 32 MHz, supports IEC60730 safety compliance, and targets weight scales, strain gauge interfaces, and precision process transmitters.

For engineers reviewing the R5F523E5MGFL#30 datasheet, R5F523E5MGFL#30 pinout, R5F523E5MGFL#30 application, or R5F523E5MGFL#30 equivalent, key selection criteria include its 31.25 kSPS delta-sigma sampling rate, 10-V analog input range, built-in voltage reference (2.5 V, 8 ppm/°C), CAN interface (ISO11898-1, 1 Mbps), and support for software standby mode with low-power timer operation.

Technical Context

The R5F523E5MGFL#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, 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 for simultaneous 50/60 Hz rejection at 10/54 SPS.

Power management includes three low-power modes (sleep, deep sleep, software standby), LVD with 14-level detection, and independent watchdog timer driven by a 15-kHz on-chip oscillator. Clocking supports main (1–20 MHz), sub (32.768 kHz), and PLL inputs, with CAC for frequency accuracy monitoring - critical for metrology-grade timing stability.

FAQ

What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E5MGFL#30?

The R5F523E5MGFL#30 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 R5F523E5MGFL#30. The device achieves this rate with fMOD = 4 MHz and supports lower rates down to 3.8 SPS for enhanced noise rejection.

Does R5F523E5MGFL#30 support ±10-V analog inputs?

Yes, R5F523E5MGFL#30 supports ±10-V analog inputs via its HVAIN0–HVAIN3 pins. As specified in Figure 1.1 and Table 1.3, the "M" in the part number denotes the 31.25 kSPS variant with 10-V analog input range, and the "K"/"L"/"M" suffix explicitly defines ±10-V capability. These pins are electrically isolated from standard I/O and tolerate the full ±10-V range.

What is the operating temperature range for R5F523E5MGFL#30?

R5F523E5MGFL#30 is rated for an operating ambient temperature range of –40°C to +85°C (D-version). This is indicated by the "D" in the part number suffix per Figure 1.1, and confirmed in Table 1.3 where all R5F523E5xxx entries list "–40 to +85°C" under Operating Temperature.

Which package type does R5F523E5MGFL#30 use?

R5F523E5MGFL#30 uses the PLQP0048KB-B package: a 48-pin LFQFP with 7 mm × 7 mm body size and 0.5 mm pin pitch. This is explicitly stated in Table 1.3 (List of Products) and verified in Figure 1.1's package coding ("FL" = LFQFP/48/0.50).

Does R5F523E5MGFL#30 include a CAN interface?

Yes, R5F523E5MGFL#30 includes one CAN channel compliant with ISO11898-1, supporting data rates up to 1 Mbps. This is documented in the "Features" section (page 1), "Outline of Specifications" (Table 1.1), and block diagram (Figure 1.2), where the RSCAN module is shown as integral to the RX23E-B Group architecture.
