Product details
Overview
R5F52106BDBM#U0 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels), 10-bit D/A converter (2 channels), RTC, ELC, MPC, and IEC60730-compliant safety functions - deployed in industrial control panels requiring deterministic real-time response and functional safety support.
For engineers reviewing the R5F52106BDBM#U0 datasheet, R5F52106BDBM#U0 pinout, R5F52106BDBM#U0 application, or R5F52106BDBM#U0 equivalent, key selection considerations include its 69-pin WLBGA package (3.91 × 4.26 mm, 0.40-mm pitch), −40°C to +85°C temperature grade, chip version B feature set (including full TPU/MTU2 timer support and RTC), and compatibility with Renesas E1 emulator via FINE interface.
Technical Context
The R5F52106BDBM#U0 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32-bit multiply-accumulate operations. Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), dedicated IWDT oscillator, and clock accuracy measurement circuit (CAC) for IEC60730 compliance.
It supports four low-power modes including deep software standby with RTC active, and uses Event Link Controller (ELC) to trigger peripheral operations (e.g., A/D conversion, timer output) without CPU intervention - enabling ultra-low-latency event-driven execution while maintaining sleep-state power efficiency.
