Product details
Overview
R5F52106BDFB#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 (16 channels, 1 μs conversion), and real-time clock with deep software standby wake-up capability - deployed in industrial control panels requiring deterministic timing and IEC60730-compliant self-diagnostic functions.
For engineers reviewing the R5F52106BDFB#30 datasheet, R5F52106BDFB#30 pinout, R5F52106BDFB#30 application, or R5F52106BDFB#30 equivalent, key selection criteria include its 144-pin LQFP package (20 × 20 mm, 0.5-mm pitch), full peripheral set including ELC, MPC, RSPI, RIIC, and dual 10-bit D/A outputs - critical for motor control feedback loops and sensor fusion systems.
Technical Context
The R5F52106BDFB#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a dedicated on-chip PLL (4–12.5 MHz input) generating 50-MHz ICLK, with independent PCLK (max 32 MHz), BCLK (max 12.5 MHz), and FCLK (max 32 MHz) domains for precise peripheral clock gating.
Its event-driven architecture includes the Event Link Controller (ELC) supporting 59 event sources - enabling timer-triggered A/D conversion, RTC alarm wake-up from deep software standby, and direct peripheral-to-peripheral transfers without CPU intervention - essential for low-latency, energy-efficient embedded control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52106ADFP#V0 | Chip version A, 100-pin LQFP, 256 KB flash, same peripherals except no external bus, TPU, or RTC - lacks deep software standby RTC wake-up. | Targeted for cost-sensitive consumer appliances without stringent real-time logging or ultra-low-power requirements. | Select when board space is constrained and external bus/RTC functionality is unnecessary - saves ~$0.80/unit but sacrifices industrial-grade power management. |
| R5F52106BDFP#30 | Same chip version B and memory config, but 100-pin LQFP (PLQP0100KB-A) - reduced I/O count (84 vs. 122), no external bus, no TPU, no RTC, fewer SCI channels (6 vs. 13). | Suitable for compact HMI controllers or sensor nodes where full peripheral set is unused. | Choose for smaller footprint and lower assembly cost where MTU2, ELC, and RTC are not required - maintains same firmware compatibility within RX210 family. |
Compared with R5F52106ADFP#V0 and R5F52106BDFP#30, the R5F52106BDFB#30 uniquely delivers full peripheral integration (including RTC, TPU, ELC, and external bus) in a 144-pin LQFP package - making it the only RX210 variant capable of standalone motor control, time-stamped diagnostics, and expansion-capable industrial designs without external glue logic.

FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F52106BDFB#30?
The R5F52106BDFB#30 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS (Dhrystone MIPS) performance. This metric reflects its execution capability under real-world embedded workloads, validated per the industry-standard Dhrystone 2.1 benchmark. The RXv1 core achieves this through a 5-stage pipeline, variable-length instruction encoding, and zero-wait-state access to both flash and SRAM - enabling deterministic real-time response in control applications.
Does the R5F52106BDFB#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F52106BDFB#30 includes hardware-assisted features specifically for IEC60730 Class B compliance, including self-diagnostic routines for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM test assist functions. These capabilities reduce software validation burden and enable certified safety firmware development - confirmed in Renesas Application Note R01AN1409EU0100.
What package type and pin count does the R5F52106BDFB#30 use, and is it RoHS-compliant?
The R5F52106BDFB#30 uses a 144-pin LQFP package (PLQP0144KA-A) measuring 20 × 20 mm with 0.5-mm pitch and matte tin (Sn) lead finish. It is fully RoHS-compliant and halogen-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard reflow assembly. The exposed pad enhances thermal dissipation in industrial ambient conditions up to +85°C.
How many A/D converter channels does the R5F52106BDFB#30 support, and what is the minimum conversion time?
The R5F52106BDFB#30 integrates a 12-bit S12AD module with 16 input channels (AN000–AN015). Its minimum conversion time is 1.0 μs per channel when operating with ADCLK at 50 MHz - verified in the R01DS0041EJ0150 datasheet Section 24.3.2. This enables high-speed sampling for multi-axis motor current sensing and real-time FFT-based vibration analysis.
Can the R5F52106BDFB#30 generate complementary PWM waveforms with dead-time control for 3-phase inverter drives?
Yes, the R5F52106BDFB#30's MTU2 (Multi-function Timer Pulse Unit 2) supports complementary PWM output mode with programmable dead-time insertion across six channels (MTIOA0–MTIOA5 and MTIOB0–MTIOB5). This is coordinated by the Port Output Enable 2 (POE2) module, which controls high-impedance states during fault conditions - enabling safe, efficient 3-phase inverter gate driving without external dead-time ICs.
