Renesas R5F52318AGFL#30

Overview

R5F52318AGFL#30 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 512 KB on-chip flash, 64 KB SRAM, and 8 KB data flash. It integrates a single-precision IEEE 754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DACs, USB 2.0 full-speed host/function/OTG, CAN 2.0B, SD host interface, capacitive touch sensing unit (24 keys), and TSIP-Lite encryption engine. It targets industrial HMI and embedded control systems requiring real-time responsiveness, secure firmware, and mixed-signal integration.

For engineers reviewing the R5F52318AGFL#30 datasheet, R5F52318AGFL#30 pinout, R5F52318AGFL#30 application, or R5F52318AGFL#30 equivalent, key selection considerations include its PLQP0048KB-B 48-pin LFQFP package (7 × 7 mm, 0.5 mm pitch), −40 to +105°C extended temperature rating (G version), absence of RTC and external bus support in this variant, and confirmed compatibility with Renesas' e2 studio and CS+ IDE toolchains.

Technical Context

The R5F52318AGFL#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 88.56 DMIPS at 54 MHz. Its memory subsystem includes no-wait 54 MHz SRAM access, flash accelerator for zero-wait-state execution above 32 MHz, and background operation (BGO) for 8 KB data flash programming during active code execution.

Peripheral integration centers on event-driven operation via the Event Link Controller (ELC), which enables timer-triggered ADC conversions, PWM waveform updates, and DMA transfers without CPU intervention. Clock management supports independent domain control: ICLK (54 MHz system clock), PCLKA (54 MHz for MTU2), PCLKD (54 MHz for ADC), and BCLK (32 MHz for external bus-disabled in this 48-pin variant).

FAQ

What is the maximum operating frequency and CPU performance of the R5F52318AGFL#30?

The R5F52318AGFL#30 operates at a maximum system clock frequency of 54 MHz using its RXv2 CPU core, delivering 88.56 DMIPS of processing performance. Its 5-stage pipeline, variable-length instruction set, and integrated FPU enable deterministic real-time execution for motor control, sensor fusion, and protocol stack processing-all verified in the official Renesas R01DS0261EJ0120 datasheet.

Does the R5F52318AGFL#30 include a real-time clock (RTC) module?

No, the R5F52318AGFL#30 does not include an RTC module. According to Table 1.2 in the R01DS0261EJ0120 datasheet, RTC functionality is explicitly marked as "Not supported" for all 48-pin RX231 variants-including R5F52318AGFL#30. This omission is package-dependent; 100-pin versions (e.g., R5F52318AGLA#20) retain RTC support.

What package type and pin count does the R5F52318AGFL#30 use?

The R5F52318AGFL#30 uses the PLQP0048KB-B package: a 48-pin Low-Profile Quad Flat Package measuring 7 × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package is confirmed in Table 1.4 (G-version products) and Figure 1.1 of the R01DS0261EJ0120 datasheet, and is distinct from larger 64- and 100-pin variants in the RX231 family.

Which communication interfaces are available on the R5F52318AGFL#30?

The R5F52318AGFL#30 supports USB 2.0 full-speed host/function/OTG, CAN 2.0B, five SCI channels (asynchronous/clock-synchronous), one I2C bus interface, one RSPI, one SSI, and one SD host interface. Per Table 1.2, it excludes external bus and RTC-but retains full SDHI and CAN capability unlike lower-pin-count variants such as the 48-pin RX230 series.

What is the operating temperature range specified for the R5F52318AGFL#30?

The R5F52318AGFL#30 is rated for an operating ambient temperature range of −40 to +105°C, as designated by the "G" suffix in its part number and confirmed in Table 1.4 of the R01DS0261EJ0120 datasheet. This extended grade makes it suitable for under-hood automotive auxiliary systems, industrial drives, and outdoor equipment deployments.
