Product details

Overview

R5F52203BDFL#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (49 DMIPS), featuring 64 KB on-chip flash, 8 KB SRAM, 8 KB data flash, 12-bit A/D converter (1.56 µs conversion), and integrated RTC with IEC60730 support - deployed in industrial sensor nodes requiring deterministic real-time control and low-voltage operation down to 1.62 V.

For engineers reviewing the R5F52203BDFL#30 datasheet, R5F52203BDFL#30 pinout, R5F52203BDFL#30 application, or R5F52203BDFL#30 equivalent, this page delivers verified package mapping (PLQP0048KB-A, 48-pin LQFP), validated peripheral channel counts (8-channel A/D, 3 SCI channels including IrDA, 2 comparator inputs), confirmed low-power modes (sleep, all-module clock stop, software standby), and exact functional alignment with RX220 Group specifications per Rev.1.10 datasheet.

Technical Context

The R5F52203BDFL#30 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its ELC (Event Link Controller) allows direct module triggering without CPU intervention, supporting concurrent peripheral operation during sleep mode.

It integrates dedicated clock domains (ICLK/PCLK/FCLK all up to 32 MHz), independent watchdog timer driven by a 125-kHz on-chip oscillator, and hardware-accelerated CRC calculation using selectable polynomials (X⁸+X²+X+1, X¹⁶+X¹⁵+X²+1, X¹⁶+X¹²+X⁵+1) - all essential for functional safety compliance in IEC60730 Class B applications.

FAQ

What is the maximum operating frequency of the R5F52203BDFL#30 and under what voltage conditions?

The R5F52203BDFL#30 operates at a maximum frequency of 32 MHz when supplied with VCC ≥ 2.7 V. At lower voltages (1.62 V to 2.7 V), the maximum frequency is derated to 8 MHz to ensure timing margin and stability. This dual-speed capability enables flexible power management in battery-powered systems without requiring external voltage scaling circuitry.

How many A/D input channels does the R5F52203BDFL#30 support, and which pins are assigned?

The R5F52203BDFL#30 supports exactly 8 A/D input channels (AN000–AN007), mapped to physical pins P40, P41, P05, P26, P27, P30, P31, and PE3 per the 48-pin LQFP pinout. These share functions with general-purpose I/O and require proper analog domain biasing (AVCC0, AVSS0, VREFH0, VREFL0) for accurate 12-bit conversion.

Does the R5F52203BDFL#30 include hardware support for IEC60730 functional safety compliance?

Yes, the R5F52203BDFL#30 includes dedicated hardware features for IEC60730 Class B compliance: self-diagnostic A/D test mode, analog input disconnection detection, clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, and RAM test assist functions - all documented in the R01DS0130EJ0110 datasheet.

What communication interfaces are available on the R5F52203BDFL#30, and are there any limitations compared to larger RX220 variants?

The R5F52203BDFL#30 provides 3 SCI channels (SCI1, SCI5, SCI6), 1 I²C bus interface (RIIC), and 1 RSPI channel. It lacks SCIf (SCI12), the fourth SCI channel, and the full 6-channel MTU2 set found in 100-pin variants. SCI5 supports IrDA via dedicated IRTXD5/IRRXD5 pins - confirmed in Table 1.2 and Figure 1.5 of the datasheet.

What is the data flash endurance specification for the R5F52203BDFL#30, and how is it managed in firmware?

The R5F52203BDFL#30 includes 8 KB of on-chip data flash rated for 100,000 erase/write cycles. Erasing and programming are performed autonomously by the flash control unit without CPU intervention, allowing background operation. Firmware must use Renesas-provided FDL (Flash Development Library) APIs to manage sector erase, write, and verify operations safely and reliably.
