Product details
Overview
R5F52205BGFL#50 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz, delivering 49 DMIPS performance with 128 KB on-chip flash, 8 KB SRAM, and 8 KB data flash. It integrates a 12-bit A/D converter (16 channels, 1.56 µs conversion), RTC with calendar support, ELC for event-driven peripheral operation, and IEC60730-compliant safety functions - deployed in industrial control panels requiring deterministic real-time response and functional safety certification.
For engineers reviewing the R5F52205BGFL#50 datasheet, R5F52205BGFL#50 pinout, R5F52205BGFL#50 application, or R5F52205BGFL#50 equivalent, this page delivers verified package mapping (PLQP0048KB-A, 48-pin LQFP), confirmed pin functions including MTU2 timer I/O, SCI5/SCI12/IrDA/RIIC/RSPI interfaces, and validated alternative options for migration or second sourcing in temperature-critical embedded designs.
Technical Context
The R5F52205BGFL#50 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its clock system includes dedicated oscillators for main (up to 20 MHz crystal), sub-clock (32.768 kHz), high-speed on-chip (HSOSC), low-speed on-chip (LSOSC), and IWDT-dedicated 125 kHz sources - all managed via independent ICLK/PCLK/FCLK domains.
Peripheral coordination is handled by the Event Link Controller (ELC), which routes 46 types of event signals directly to modules like MTU2, TMR, CMT, and S12AD without CPU intervention. The Multi-function Pin Controller (MPC) enables flexible I/O assignment across PB0–PB5 and PC0–PC3, supporting port switching for pin reuse in space-constrained 48-pin layouts.

The R5F52205BGFL#50 operates at a maximum frequency of 32 MHz and delivers 49 DMIPS of processing performance. This is achieved using the 32-bit RX CPU core with a 5-stage pipeline and variable-length instruction set. The R5F52205BGFL#50 maintains full performance across its entire operating voltage range (1.62–5.5 V) and temperature range (−40°C to +105°C), with no wait states on flash or SRAM access at full speed.
Which package type and pin count does the R5F52205BGFL#50 use?
The R5F52205BGFL#50 uses the PLQP0048KB-A package: a 48-pin LQFP measuring 7 mm × 7 mm with 0.5 mm pitch. This package supports 34 general-purpose I/O pins, 8 analog inputs (AN000, AN003–AN004, AN006, AN009–AN012), and full peripheral functionality including SCI1/5/6, SCIf (SCI12), RIIC, RSPI, MTU2, and RTC - as confirmed in Table 1.2 of the official datasheet.
Does the R5F52205BGFL#50 support IEC60730 Class B compliance features?
Yes, the R5F52205BGFL#50 includes integrated hardware-assisted functions for IEC60730 Class B compliance, including self-diagnostic routines for the A/D converter, clock-frequency accuracy measurement (CAC), independent watchdog timer (IWDT), RAM testing, and analog input disconnection detection. These features are implemented in silicon and documented in the R01DS0130EJ0110 datasheet - eliminating the need for external diagnostic components in certified appliance designs.

All interfaces operate independently under PCLK control and are fully accessible in the 48-pin PLQP0048KB-A package.
How does the Multi-function Pin Controller (MPC) benefit PCB design for the R5F52205BGFL#50?
The MPC in the R5F52205BGFL#50 enables dynamic assignment of peripheral functions to multiple physical pins - specifically PB0–PB5 and PC0–PC3 in the 48-pin package. This allows designers to resolve pin conflicts during layout, repurpose pins for alternate functions (e.g., switching PB1 from MTIOC0C to SS12#), and simplify routing in dense industrial PCBs without changing the MCU or footprint. The feature is fully supported in Renesas' e2 studio and CS+ toolchains.
