Product details
Overview
R5F52108CDFM#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller designed for industrial and consumer embedded control applications. It operates at up to 50 MHz (78 DMIPS), integrates 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, a 12-bit A/D converter (16 channels, 1 µs conversion), and dual 10-bit D/A converters. It supports IEC60730 safety compliance functions and real-time clock with deep software standby wake-up capability.
For engineers reviewing the R5F52108CDFM#30 datasheet, R5F52108CDFM#30 pinout, R5F52108CDFM#30 application, or R5F52108CDFM#30 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064KB-A) package, −40°C to +85°C temperature grade (D version), chip version C feature set (including RTC, full ELC, and MTU2), and suitability for resource-constrained, safety-aware control systems requiring low-power operation and peripheral flexibility.
Technical Context
The R5F52108CDFM#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its memory subsystem includes zero-wait-state 50-MHz flash and SRAM, plus dedicated 8-KB data flash with 100,000 erase/program cycles and CPU-transparent operation.
Peripherals are orchestrated via the Event Link Controller (ELC), allowing direct module-to-module triggering without CPU intervention-critical for deterministic timing in motor control and sensor acquisition. The chip version C configuration enables full RTC functionality, 6-channel MTU2 timers with complementary PWM, and 16-channel 12-bit A/D with synchronized sampling and self-diagnostic support.
