Overview
R5F523E6NGFP#30 from Renesas is a 32-bit RXv2 microcontroller optimized for high-precision industrial sensing and measurement, 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.
For engineers reviewing the R5F523E6NGFP#30 datasheet, R5F523E6NGFP#30 pinout, R5F523E6NGFP#30 application, or R5F523E6NGFP#30 equivalent, this MCU delivers calibrated high-resolution analog front-end performance in a 100-pin LFQFP package with industrial temperature grade (–40°C to +105°C), making it suitable for load cell, strain gauge, and precision sensor signal conditioning in factory automation and test equipment.
Technical Context
The R5F523E6NGFP#30 implements the RXv2 CPU core with IEEE 754-compliant single-precision FPU, 32-bit multiply-accumulate DSP instructions, and memory protection unit (MPU). Its analog subsystem centers on a dedicated 24-bit delta-sigma A/D converter (DSADB) synchronized to PCLKC (up to 16 MHz), with fourth- and fifth-order sinc digital filters, offset/gain error calibration, and ±5-V HVAIN input capability.
Real-time control is enabled by six-channel MTU2a timers, event link controller (ELC) for interrupt-free peripheral coordination, and low-power modes including software standby with active LPT. Clock management includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.
