Overview
R5F52206BDFL#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (49 DMIPS), featuring 256 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (8 channels), and integrated RTC with IEC60730 support - deployed in industrial control panels requiring deterministic real-time response and functional safety compliance.
For engineers reviewing the R5F52206BDFL#30 datasheet, R5F52206BDFL#30 pinout, R5F52206BDFL#30 application, or R5F52206BDFL#30 equivalent, key selection criteria include its 48-pin LQFP (PLQP0048KB-A) package, −40°C to +85°C temperature grade, 1.62–5.5 V supply range, ELC event-driven peripheral activation, and MPC pin function remapping capability for layout flexibility.
Technical Context
The R5F52206BDFL#30 implements the 32-bit RXv1 core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling ultra-compact code density and single-cycle 32×32-bit multiplication. Its CISC design supports DSP instructions and 64-bit accumulator operations for embedded signal processing tasks.
It integrates an Event Link Controller (ELC) that routes 46 event signals directly to peripherals without CPU intervention, and a Multi-function Pin Controller (MPC) allowing dynamic assignment of functions like MTU2, SCI, or RIIC to multiple I/O pins - critical for PCB reuse across variants in cost-sensitive industrial designs.

FAQ
What is the maximum operating frequency of the R5F52206BDFL#30 and under what voltage conditions?
The R5F52206BDFL#30 operates at a maximum frequency of 32 MHz when powered at 2.7 V to 5.5 V. At 1.62 V to 2.7 V, the maximum frequency is derated to 8 MHz. This dual-voltage scalability allows the R5F52206BDFL#30 to serve both high-performance control loops and ultra-low-power battery-backed applications without changing MCU families.
Does the R5F52206BDFL#30 support IEC60730 Class B compliance out of the box?
Yes, the R5F52206BDFL#30 includes hardware-assisted features required for IEC60730 Class B: clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, A/D converter self-diagnostic, analog input disconnection detection, and RAM test assistance. These are documented in the R01DS0130EJ0110 datasheet and enable certified safety firmware implementation without external components.
How many A/D converter channels does the R5F52206BDFL#30 provide, and what is their resolution and speed?
The R5F52206BDFL#30 integrates an 8-channel, 12-bit successive-approximation A/D converter (S12AD). Each conversion completes in 1.56 μs when ADCLK runs at 32 MHz. Channels AN000–AN007 are accessible on dedicated pins, with sample-and-hold, scan modes, and double-trigger capability - sufficient for multi-sensor monitoring in compact industrial controllers.
What communication interfaces are available on the R5F52206BDFL#30, and which ones are supported in its 48-pin package?
The R5F52206BDFL#30 supports 3 × SCI (channels 1, 5, 9), 1 × RIIC, and 1 × RSPI. In the 48-pin PLQP0048KB-A package, SCI12 and SCIf functionality are omitted, and only three SCI channels (SCI1, SCI5, SCI9) are implemented. IrDA is enabled via SCI5, and RIIC/RSPI operate at full spec - matching the needs of sensor hubs and HMI backplanes.
Can the R5F52206BDFL#30 operate from a single-cell LiFePO₄ battery, and what low-power modes does it support?
Yes, the R5F52206BDFL#30 supports 1.62 V minimum supply, making it compatible with single-cell LiFePO₄ batteries (nominal 3.2 V, discharge down to ~2.5 V). It offers three low-power modes: Sleep (CPU stopped, peripherals active), All-module clock stop (all clocks halted except sub-clock), and Software standby (RTC + LVD active, sub-μA current) - enabling energy harvesting and battery longevity in remote sensors.
