Product details
Overview
R5F523E6NDBS#00 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision analog measurement in industrial sensor nodes and metering systems. It integrates a 24-bit delta-sigma ADC with 31.25 kSPS max sampling rate, ±5-V analog input range, rail-to-rail programmable gain instrumentation amplifier (gain = 1–128), on-chip excitation current sources (50–1000 µA), and a low-drift 2.5-V voltage reference (8 ppm/°C). Operating at up to 32 MHz with 256 KB flash and 32 KB SRAM, it supports CAN, SCI, I²C, and RSPI interfaces.
For engineers reviewing the R5F523E6NDBS#00 datasheet, R5F523E6NDBS#00 pinout, R5F523E6NDBS#00 application, or R5F523E6NDBS#00 equivalent, key selection criteria include its 31.25 kSPS delta-sigma ADC performance at ±5 V full-scale, TFBGA100 package footprint, integrated excitation current matching (±0.2%), and IEC60730-compliant self-diagnostic features for safety-critical analog acquisition.
Technical Context
The R5F523E6NDBS#00 implements the RXv2 CPU core with IEEE 754-compliant single-precision FPU, 64 DMIPS @ 32 MHz, and memory protection unit (MPU) for secure embedded execution. Its analog subsystem centers on the DSADB module - a 24-bit delta-sigma ADC with fourth- and fifth-order sinc filters, simultaneous 50/60 Hz rejection at 10/54 SPS, and offset drift of 4 nV/°C (gain = 64–128).
Clock management includes PLL, main/sub oscillators, and CAC for frequency accuracy monitoring; power control supports three low-power modes with LPT active during software standby. The ELC enables event-triggered peripheral operation without CPU wake-up, critical for deterministic sensor data acquisition in energy-constrained applications.
