Product details
Overview
R5F52106BDFN#30 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 (12 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.
For engineers reviewing the R5F52106BDFN#30 datasheet, R5F52106BDFN#30 pinout, R5F52106BDFN#30 application, or R5F52106BDFN#30 equivalent, this page delivers verified package mapping (PLQP0080KB-A, 80-pin LQFP), validated peripheral channel counts (6 SCI, 1 RIIC, 1 RSPI, 12-channel S12AD), confirmed low-power modes (deep software standby with RTC active), and two field-validated alternative parts with documented functional trade-offs.
Technical Context
The R5F52106BDFN#30 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip debugging via FINE interface. Its RX CPU core supports 64-bit accumulator results from 32×32-bit operations and executes multiplication in one cycle.
It integrates event-driven operation via ELC (59 event sources), enabling timer and peripheral activation without CPU intervention, and uses MPC to remap peripheral functions across multiple pins - critical for PCB layout flexibility in space-constrained industrial modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52106ADFN#V0 | Chip version A; lacks RTC and TPU; only 4 SCI channels vs. 6; no ELC or MPC. | Suitable for cost-sensitive, non-time-critical control where RTC and event-driven peripheral coordination are unnecessary. | Select when RTC, ELC, or MPC are not required - reduces BOM cost but sacrifices advanced timing and safety features. |
| R5F52106BDFP#30 | Same chip version B, same memory and peripherals, but 100-pin LQFP (PLQP0100KB-A) - adds 16 more GPIOs and 2 extra ADC channels. | Preferred for designs needing expanded I/O or additional analog inputs (e.g., multi-sensor environmental monitors). | Choose for higher I/O density or future-proofing; requires larger PCB footprint and different land pattern. |
Compared with R5F52106ADFN#V0, the R5F52106BDFN#30 adds RTC, ELC, MPC, and 2 extra SCI channels - essential for time-stamped diagnostics and deterministic peripheral coordination. Against R5F52106BDFP#30, it trades 16 GPIOs and 2 ADC inputs for compact 80-pin layout - optimizing board area in space-constrained industrial enclosures.
