Product details
Overview
R5F523E5SGNF#40 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision industrial sensor signal conditioning, featuring dual 24-bit delta-sigma ADCs (DSAD0/DSAD1), rail-to-rail programmable gain instrumentation amplifiers (PGA ×8 gain settings), 2.5 V low-drift voltage reference (10 ppm/°C), four excitation current sources (50–1000 µA), and integrated CAN 2.0B interface. It operates at up to 32 MHz with 128 KB flash, 16 KB SRAM, and 8 KB data flash, targeting thermocouple and RTD measurement systems in harsh environments.
For engineers reviewing the R5F523E5SGNF#40 datasheet, R5F523E5SGNF#40 pinout, R5F523E5SGNF#40 application, or R5F523E5SGNF#40 equivalent, this device delivers verified 23-bit effective resolution at 7.6 SPS, simultaneous 50/60 Hz rejection, ±0.2% excitation current matching, and IEC60730-compliant self-diagnostic support - critical for functional safety in industrial temperature monitoring and process control designs.
Technical Context
The R5F523E5SGNF#40 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, programmable gain instrumentation amplifiers (gain = 1–128), and dedicated analog front-end resources including bias voltage generator (VBIAS = (AVCC0 + AVSS0)/2), low-side switch (10 Ω max), and voltage/reference fault detectors. Its RXv2 CPU executes at 32 MHz with 64 DMIPS, includes single-precision FPU (IEEE 754), MPU, and ELC for interrupt-free module linking.
It supports dual operating modes: Normal mode (7.6–15625 SPS) and Low-power mode (1.9–3906 SPS) for DSAD, while maintaining full peripheral operation including CAN, SCI, RSPI, and RIIC. The 40-pin HWQFN package (PWQN0040KD-A, 6 × 6 mm, 0.5 mm pitch) provides 16 general I/O pins, 4 differential DSAD inputs, and 4 S12AD channels - validated per Table 1.2 of R01DS0330EJ0130 Rev.1.30.

FAQ
What is the maximum effective resolution achievable with the R5F523E5SGNF#40's delta-sigma ADCs?
The R5F523E5SGNF#40 achieves up to 23-bit effective resolution at 7.6 SPS with gain = 1 and output data rate = 7.6 SPS, as specified in the datasheet (R01DS0330EJ0130 Rev.1.30, Page 1). This performance is enabled by its fourth-order sinc filter, low-noise PGA, and on-chip 2.5 V reference - verified under calibrated conditions with proper layout and grounding.
Does the R5F523E5SGNF#40 support simultaneous sampling across both delta-sigma ADC units?
Yes, the R5F523E5SGNF#40 supports inter-unit A/D conversion synchronized start, allowing DSAD0 and DSAD1 to begin conversion simultaneously via software trigger or ELC event. This capability is explicitly documented in the "Analog functions" section of the datasheet (Page 1) and enables coherent multi-sensor acquisition without timing skew.
What is the operating temperature grade of the R5F523E5SGNF#40, and how is it encoded in the part number?
The R5F523E5SGNF#40 is rated for –40°C to +105°C operation (G-grade), indicated by the 'G' in the seventh character of the part number per Figure 1.1 (Page 8). This extended temperature qualification is confirmed in Table 1.3 (Page 7) and applies to all variants ending in 'G', ensuring reliability in high-ambient industrial environments.
Can the R5F523E5SGNF#40 perform self-calibration of its delta-sigma ADC offset and gain errors?
Yes, the R5F523E5SGNF#40 includes built-in offset error and gain error calibration for both DSAD units, as stated in the "Analog functions" section (Page 1). Calibration can be executed in-system using dedicated registers and does not require external equipment - supporting maintenance-free operation in deployed field instruments.
How many excitation current sources does the R5F523E5SGNF#40 provide, and what are their key matching specifications?
The R5F523E5SGNF#40 provides four excitation current sources (IEXC0–IEXC3) with programmable output from 50 µA to 1000 µA. Their key matching specifications are ±0.2% current matching and 5 ppm/°C drift matching, as defined in the "Analog functions" section (Page 1) - enabling high-accuracy 3- and 4-wire RTD measurements without external trimming.
