Overview

R5F52106BDFL#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), 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 R5F52106BDFL#30 datasheet, R5F52106BDFL#30 pinout, R5F52106BDFL#30 application, or R5F52106BDFL#30 equivalent, key selection criteria include its 48-pin LQFP package, −40°C to +85°C temperature grade, 50-MHz operation with no wait states, integrated event link controller for low-latency peripheral triggering, and support for IEC60730 self-test functions including A/D diagnostic and clock accuracy measurement.

Technical Context

The R5F52106BDFL#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual timer subsystems: MTU2 (6-channel 16-bit) for complementary PWM and phase counting, and TPU (6-channel 16-bit) for input capture and synchronized A/D triggers - both controllable via Event Link Controller without CPU intervention.

Its clock system includes PLL (4–12.5 MHz input), sub-clock oscillator (32.768 kHz), dedicated IWDT oscillator (125 kHz), and Clock Accuracy Check (CAC) circuit. Power management supports four low-power modes, deep software standby with RTC active, and voltage detection across three independent circuits (LVDA0–LVDA2) with configurable thresholds.

FAQ

What is the maximum operating frequency and CPU performance of the R5F52106BDFL#30?

The R5F52106BDFL#30 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS of processing performance. Its RXv1 CPU core supports single-cycle 32×32-bit multiplication with 64-bit accumulation, enabling efficient signal processing and real-time control tasks without external co-processors. This performance level is sustained across its full 1.62–5.5 V supply range.

Does the R5F52106BDFL#30 support IEC60730 functional safety requirements?

Yes, the R5F52106BDFL#30 includes dedicated hardware features for IEC60730 Class B compliance: self-diagnostic A/D converter, clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assist functions, and analog input disconnection detection. These reduce external component count and simplify safety certification for household and industrial appliances.

What package type and pin count does the R5F52106BDFL#30 use?

The R5F52106BDFL#30 uses a 48-pin LQFP package (PLQP0048KB-A) with 7 × 7 mm body size and 0.5-mm pitch. It features 34 general-purpose I/O pins, 16 dedicated A/D input pins, and supports 5-V tolerant operation on selected I/Os - making it suitable for space-constrained industrial and consumer designs where board area and assembly cost are critical.

Can the R5F52106BDFL#30 operate from a single low-voltage supply?

Yes, the R5F52106BDFL#30 operates from a single supply ranging from 1.62 V to 5.5 V. At 1.62–1.8 V, it supports up to 20 MHz operation; at 1.8–2.7 V, up to 32 MHz; and at 2.7–5.5 V, full 50 MHz performance. This wide voltage range simplifies power design and enables direct battery operation (e.g., 3.3 V or 5 V rails) without external regulators in many applications.

What communication interfaces are integrated into the R5F52106BDFL#30?

The R5F52106BDFL#30 integrates SCI (4 channels: SCI1, SCI5, SCI6, SCI8), I2C bus interface (RIIC, 1 channel, 400 kbps), and RSPI (1 channel, 16 Mbps). It does not include CAN or Ethernet. The SCI supports asynchronous, clock-synchronous, and smart card modes; RIIC is SMBus-compatible; RSPI supports master/slave operation with 8–32 bit frame lengths and double-buffered TX/RX.
