For engineers reviewing the R5F52315CDFL#30 datasheet, R5F52315CDFL#30 pinout, R5F52315CDFL#30 application, or R5F52315CDFL#30 equivalent, this page delivers verified technical context, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), confirmed peripheral set for the RX231 Group D-version 48-pin variant, and two validated alternative parts with documented functional and packaging differences.

Technical Context

The R5F52315CDFL#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit single-precision FPU, 88.56 DMIPS at 54 MHz, and memory protection unit (MPU). Its clock system includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL supporting 48 MHz USB clock generation.

Peripheral integration includes one CAN channel (ISO 11898-1, up to 1 Mbps), seven SCI channels (asynchronous/clock-synchronous/smart card), one I²C bus interface (400 kbps), one RSPI (16 Mbps), one serial sound interface, and event link controller (ELC) enabling interrupt-free inter-module triggering - all configured via multi-function pin controller (MPC) for flexible I/O assignment.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F52315CDFL#30?

The R5F52315CDFL#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 54 MHz, delivering 88.56 DMIPS performance. It implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip FPU compliant to IEEE 754 for single-precision floating-point operations. This architecture enables deterministic real-time execution critical for motor control and sensor processing in the R5F52315CDFL#30.

Does the R5F52315CDFL#30 support USB and CAN interfaces simultaneously?

Yes, the R5F52315CDFL#30 integrates both USB 2.0 full-speed host/function/OTG and a single-channel CAN module compliant with ISO 11898-1 (up to 1 Mbps). These interfaces operate independently with dedicated clock domains - USB uses its own PLL-derived 48 MHz clock, while CAN uses the peripheral clock (PCLKB). This dual-interface capability makes the R5F52315CDFL#30 suitable for devices requiring local configuration (USB) and fieldbus communication (CAN), such as industrial gateways.

What package type and pin count does the R5F52315CDFL#30 use?

The R5F52315CDFL#30 is packaged in PLQP0048KB-B: a 48-pin Low-Profile Quad Flat Package with 7 mm × 7 mm body size and 0.5 mm lead pitch. This RoHS-compliant package supports reflow soldering and provides 34 general-purpose I/O pins (including 5-V tolerant and open-drain options), matching the RX231 Group's 48-pin variant specification in the official datasheet.

How much flash and RAM memory does the R5F52315CDFL#30 include?

The R5F52315CDFL#30 contains 128 KB of on-chip flash memory for program code and constants, and 32 KB of SRAM for runtime variables and stack - both accessible without wait states at full 54 MHz operation when configured per datasheet timing guidelines. It also includes 8 KB of data flash rated for 1,000,000 program/erase cycles, used for parameter storage and firmware updates in the R5F52315CDFL#30.

Is the R5F52315CDFL#30 suitable for IEC 60730 safety compliance?

Yes, the R5F52315CDFL#30 includes multiple hardware features supporting Class B compliance per IEC 60730, including self-diagnostic functions for the A/D converter and clock frequency accuracy measurement circuit (CAC), RAM test assistance using the data operation circuit (DOC), and independent watchdog timer (IWDT) with dedicated low-speed oscillator. These capabilities reduce software validation burden and are explicitly documented in the R5F52315CDFL#30 datasheet for safety-critical applications.
