Renesas R5F523E6MGFM#30

Overview

R5F523E6MGFM#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing, featuring a 24-bit delta-sigma ADC with 31.25 kSPS max sampling rate, ±5-V analog input range, 256 KB on-chip flash, 32 KB SRAM, and integrated programmable gain instrumentation amplifier (PGA) with gain up to 128. It operates at up to 32 MHz and supports CAN, SCI, I²C, and RSPI interfaces in a 64-pin LFQFP package.

For engineers reviewing the R5F523E6MGFM#30 datasheet, R5F523E6MGFM#30 pinout, R5F523E6MGFM#30 application, or R5F523E6MGFM#30 equivalent, this MCU delivers calibrated high-resolution analog acquisition, low-drift voltage reference (2.5 V, 8 ppm/°C), excitation current sources (50–1000 µA), and IEC60730-compliant self-test functions - critical for load cell, pressure sensor, and weigh scale systems requiring metrological accuracy and functional safety.

Technical Context

The R5F523E6MGFM#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU). Its analog subsystem centers on the DSADB module synchronized to PCLKC (≤16 MHz), supporting fourth- and fifth-order sinc digital filters and simultaneous 50/60 Hz rejection at 10/54 SPS.

It integrates dual A/D converters: a 24-bit delta-sigma unit (8-channel differential, 31.25 kSPS, ±5 V range) and an 8-channel 12-bit SAR ADC (1.4 µs conversion time). The analog front end includes rail-to-rail PGA, ±10-V HVAIN pins (though unused in M-variant), two 50–1000 µA excitation current sources with ±0.2% matching, and bias voltage generator (AVCC0 + AVSS0)/2.

FAQ

What is the maximum sampling rate of the 24-bit delta-sigma ADC in R5F523E6MGFM#30?

The R5F523E6MGFM#30 supports a maximum sampling rate of 31.25 kSPS for its 24-bit delta-sigma ADC. This is confirmed in Table 1.3 of the datasheet (R01DS0402EJ0100) under the M-variant specification, which defines the part as having "31.25 kSPS" sampling capability and ±5-V analog input range. Higher rates (125 kSPS) apply only to B/J/K/L variants.

Does R5F523E6MGFM#30 include an LCD controller?

No, R5F523E6MGFM#30 does not include an LCD controller. Per Figure 1.1 and Table 1.3, the "M" suffix denotes a variant with 31.25 kSPS DSADC, ±5-V input range, and no LCD driver. This is explicitly stated as "Not available" in the LCD column for all M-variants in Table 1.2, including R5F523E6MGFM#30 in the 64-pin LFQFP configuration.

What is the operating temperature range for R5F523E6MGFM#30?

R5F523E6MGFM#30 is a D-version device rated for –40°C to +85°C ambient operating temperature. This is indicated by the "D" in the part number's temperature grade field (Figure 1.1) and confirmed in Table 1.3, where all R5F523E6xxx#xx parts with "D" suffix (e.g., R5F523E6MDFM, R5F523E6MGFM) list "–40 to +85°C" under Operating Temperature.

Which package type does R5F523E6MGFM#30 use?

R5F523E6MGFM#30 uses the PLQP0064KB-C package: a 64-pin Low-profile Quad Flat Package measuring 10 × 10 mm with 0.5 mm lead pitch. This is unambiguously specified in Table 1.3 (List of Products), where R5F523E6MGFM appears under the "64-pin LFQFP" row with package code "PLQP0064KB-C".

Does R5F523E6MGFM#30 support CAN communication?

Yes, R5F523E6MGFM#30 integrates a fully compliant CAN 2.0B module (RSCAN) supporting data rates up to 1 Mbps and 16 message boxes. This is documented in the "Communication functions" section (Page 5), Table 1.2 (CAN module listed as "Available" for all 64-pin variants), and the block diagram (Figure 1.2), confirming CAN functionality is retained in the M-variant 64-pin configuration.
