Product details
Overview
R5F523E5ADFL#30 from Renesas is a 32-bit RXv2 core MCU optimized for high-precision analog measurement in industrial sensor systems, featuring dual 24-bit delta-sigma ADCs (23-bit effective resolution at 7.6 SPS), rail-to-rail programmable gain instrumentation amplifiers (gain = 1–128), on-chip 2.5 V low-drift voltage reference (10 ppm/°C), and integrated excitation current sources (50–1000 µA, ±0.2% matching). It operates up to 32 MHz with 128 KB flash, 16 KB SRAM, and supports IEC60730-compliant diagnostics.
For engineers reviewing the R5F523E5ADFL#30 datasheet, R5F523E5ADFL#30 pinout, R5F523E5ADFL#30 application, or R5F523E5ADFL#30 equivalent, this device is selected for high-accuracy weigh scales, temperature transmitters, and strain-gauge-based process instrumentation where simultaneous multi-channel sigma-delta conversion, PGA front-end conditioning, and embedded self-test are required.
Technical Context
The R5F523E5ADFL#30 integrates two independent 24-bit delta-sigma A/D converters with fourth-order sinc filters, programmable data rates (1.9–15625 SPS), and simultaneous 50/60 Hz rejection at 10/54 SPS. Each DSAD unit supports up to six differential inputs and includes offset/gain calibration, disconnect detection assist, and external reference input capability.
Its analog front end includes a 2.5 V voltage reference (±10 ppm/°C drift), bias voltage generator ((AVCC0 + AVSS0)/2), four excitation current sources (50–1000 µA), low-side switch (10 Ω max), and voltage fault detectors for AVCC0, reference, and excitation outputs - all synchronized via the Event Link Controller (ELC) to enable deterministic, low-latency sensor acquisition without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision analog measurement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F523E6ADFL#30 | 256 KB flash, 32 KB RAM, identical analog peripherals and pinout | Required for larger firmware (e.g., Modbus TCP stack + web server) while retaining same sensor interface capabilities | Select when firmware footprint exceeds 128 KB or additional SRAM is needed for buffering high-rate DSAD data streams |
| ADS131M04IPBSR | Standalone 24-bit delta-sigma ADC (quad-channel), no MCU, no PGA, no excitation sources | Used with external host MCU; lacks integrated processing, diagnostics, or sensor excitation - requires full external signal chain | Choose only when separating analog acquisition and control functions is preferred; adds BOM cost and layout complexity versus single-chip R5F523E5ADFL#30 |
Compared with R5F523E6ADFL#30, the R5F523E5ADFL#30 offers identical analog performance and package compatibility but reduced memory - ideal for cost-sensitive, fixed-function sensor nodes. Versus ADS131M04IPBSR, it delivers full embedded intelligence and sensor-specific integration, eliminating external components and reducing system-level validation effort.

FAQ
What is the maximum effective resolution of the R5F523E5ADFL#30's delta-sigma ADCs?
The R5F523E5ADFL#30 achieves up to 23-bit effective resolution at 7.6 SPS with gain = 1 and output data rate set to minimum. This is measured under specified conditions (AVCC0 = 5.0 V, PGA bypassed, sinc4 filter enabled) and reflects actual noise-limited performance, not theoretical bit count. The device maintains ≥20-bit ENOB across its full 1.9–15625 SPS operating range.
Does the R5F523E5ADFL#30 support simultaneous sampling across both 24-bit delta-sigma ADC units?
Yes, the R5F523E5ADFL#30 supports inter-unit A/D conversion synchronized start via software or ELC trigger, ensuring phase-coherent sampling across both DSAD0 and DSAD1 units. This capability is essential for applications like multi-axis load cells or differential bridge measurements where timing skew must be eliminated.
What are the key differences between the R5F523E5ADFL#30 and R5F523E6ADFL#30?
The R5F523E5ADFL#30 and R5F523E6ADFL#30 share identical package (PLQP0048KB-B), analog peripherals, pinout, and operating specifications. The primary difference is memory: R5F523E5ADFL#30 has 128 KB flash and 16 KB RAM, while R5F523E6ADFL#30 provides 256 KB flash and 32 KB RAM - both with 8 KB data flash and same DSAD/S12AD capabilities.
Can the R5F523E5ADFL#30 operate from a 1.8 V supply?
Yes, the R5F523E5ADFL#30 supports operation down to 1.8 V on VCC, but at reduced maximum frequency: 8 MHz below 2.4 V, 16 MHz between 2.4–2.7 V, and full 32 MHz above 2.7 V. Note that AVCC0 must be ≥2.7 V for full DSAD performance; it may operate at 1.8 V only if using the 12-bit S12AD exclusively.
How does the R5F523E5ADFL#30 support IEC60730 compliance for Class B safety applications?
The R5F523E5ADFL#30 includes hardware-assisted IEC60730 functions: RAM test via Data Operation Circuit (DOC), A/D converter disconnect detection, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, and self-diagnostic routines for voltage reference and analog inputs - all documented in Renesas' Functional Safety Manual R01US0094EJ0200.
