Product details
Overview
R5F52206BGFL#50 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 with 1.56 μs conversion time, and real-time clock with calendar support. It targets industrial control, home appliance motor management, and IEC60730-compliant safety-critical embedded systems.
For engineers reviewing the R5F52206BGFL#50 datasheet, R5F52206BGFL#50 pinout, R5F52206BGFL#50 application, or R5F52206BGFL#50 equivalent, key selection considerations include its 48-pin LQFP (PLQP0048KB-A) package, −40°C to +105°C extended temperature grade, integrated ELC and MPC for event-driven low-power operation, and IrDA-capable SCI5 channel.
Technical Context
The R5F52206BGFL#50 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and 64-bit accumulator support for single-cycle 32×32-bit multiply operations. Its clock system integrates four oscillators (main, sub, high-speed on-chip, IWDT-dedicated 125 kHz) and the Clock Accuracy Check (CAC) circuit for IEC60730 compliance.
Peripheral integration includes Event Link Controller (ELC) for direct module triggering without CPU intervention, Multi-function Pin Controller (MPC) enabling flexible I/O remapping across PB/PC pins, and dual DMA engines (DMAC + DTC) supporting block, repeat, and chain transfers-critical for deterministic sensor data acquisition and motor control timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52206BDFL#50 | Same die, −40°C to +85°C temperature grade, identical pinout and memory | Suitable for commercial/industrial environments without extended thermal requirements | Select when operating ambient stays below +85°C and cost sensitivity favors standard-grade parts |
| R5F52205BGFL#50 | 128 KB flash, 8 KB SRAM, same package and temperature range; reduced peripheral count (12-channel ADC, no RTC) | Targeted at cost-optimized appliances where calendar functions and full ADC channel count are unnecessary | Choose when firmware size <128 KB and RTC/calendar features are omitted-reduces BOM cost without layout change |
Compared with R5F52206BGFL#50, the R5F52206BDFL#50 offers identical functionality at lower thermal qualification, while the R5F52205BGFL#50 trades flash/SRAM capacity and RTC for cost reduction-both retain pin compatibility and require no PCB revision.

FAQ
What is the maximum operating frequency and voltage range for the R5F52206BGFL#50?
The R5F52206BGFL#50 operates at up to 32 MHz when supplied with 2.7 V to 5.5 V. At lower voltages (1.62 V to 2.7 V), it supports up to 8 MHz operation-enabling ultra-low-power modes while maintaining core functionality. This dual-voltage capability allows flexible power architecture design in battery-backed or wide-input industrial supplies.
Does the R5F52206BGFL#50 include a real-time clock (RTC) module?
No, the R5F52206BGFL#50 does not include an RTC module. Per Table 1.2 in the datasheet, RTC support is excluded in the 48-pin LQFP (PLQP0048KB-A) package variant. The part retains sub-clock oscillator pins (XCIN/XCOUT) but lacks the internal RTC circuitry-designers requiring calendar functions must select a 64-pin or 100-pin RX220 variant.
How many ADC channels are available on the R5F52206BGFL#50?
The R5F52206BGFL#50 provides 8 channels of 12-bit analog-to-digital conversion: AN000, AN003, AN004, AN006, and AN009 through AN012. These are mapped to physical pins P40, P41, P42, P44, PE1, PE2, PE4, and PE5 per Table 1.4 and Figure 1.5. Channel count is reduced from the 16-channel capability of larger-package RX220 devices.
What communication interfaces are supported by the R5F52206BGFL#50?
The R5F52206BGFL#50 supports three SCI channels (SCI1, SCI5, SCI6), one I2C bus interface (RIIC), and one serial peripheral interface (RSPI). SCI5 includes integrated IrDA encoding/decoding. Notably absent are SCIf (SCI12), second I2C channel, and RSPI slave-only mode-features present only in 64-pin and 100-pin variants.
Is the R5F52206BGFL#50 pin-compatible with other RX220 family members in the same package?
Yes, the R5F52206BGFL#50 is pin-compatible with all other RX220 devices in the 48-pin LQFP (PLQP0048KB-A) package-including R5F52205BGFL#50 and R5F52203BGFL#50. Pin assignments, power domains, and peripheral mappings are identical; only flash/RAM capacity and enabled peripherals differ, allowing firmware scalability across memory grades without hardware change.
