Product details
Overview
R5F52315CDFM#30 from Renesas is a 32-bit RXv2 core MCU operating at up to 54 MHz (88.56 DMIPS), featuring 128 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (24 channels), and 12-bit D/A converter (2 channels). It integrates USB 2.0 full-speed host/function/OTG, CAN, SCI, I²C, RSPI, serial sound interface, capacitive touch sensing unit (CTSU), RTC, TSIP-Lite encryption engine, and operates across −40 to +85°C in industrial control applications.
For engineers reviewing the R5F52315CDFM#30 datasheet, R5F52315CDFM#30 pinout, R5F52315CDFM#30 application, or R5F52315CDFM#30 equivalent, this page delivers verified specifications, package mapping, functional context, and real-world design implications - including USB/CAN coexistence, CTSU key count limits, and SDHI absence in this variant.
Technical Context
The R5F52315CDFM#30 belongs to the RX231 Group and uses the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 32×32→64-bit multiplier, and 32-bit divider (2-cycle min). It supports little- or big-endian data arrangement and features an MPU for memory protection.
Its clock system includes main (1–20 MHz), sub-clock (32.768 kHz), and on-chip oscillators, with PLL-derived 54 MHz system clock (ICLK) and 48 MHz USB clock. The ELC enables event-driven peripheral operation without CPU intervention, and the DTC supports chain transfers for low-latency data movement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52315ADFM#30 | Same package and pinout; includes 128 KB flash, 32 KB RAM, and full CTSU support-but lacks CAN and SDHI modules | Preferred where USB + touch + A/D are primary needs and CAN is unnecessary; lower cost than C-series variants | Select when CAN interface is not required and budget constraints favor non-C security variants |
| R5F52316CDFM#30 | Same package; increases flash to 256 KB and adds 8 KB data flash-but omits D/A converter and reduces A/D channels to 12 | Suitable for firmware-intensive applications needing larger code space but less analog I/O; no DAC output capability | Choose when firmware size exceeds 128 KB and DAC functionality is unused; retains same USB/CAN/CTSU feature set |
Compared with R5F52315CDFM#30, R5F52315ADFM#30 removes CAN but keeps identical analog and USB capabilities at lower cost, while R5F52316CDFM#30 trades D/A and A/D channel count for doubled flash-offering scalable memory without changing PCB layout.

FAQ
Does R5F52315CDFM#30 support CAN communication?
Yes, R5F52315CDFM#30 includes one channel of CAN module compliant with ISO 11898-1, supporting standard and extended frames at up to 1 Mbps. This capability is confirmed in Table 1.2 of the datasheet for RX231 Group 64-pin packages and is enabled in this variant despite its "C" suffix denoting CAN inclusion. The CAN module shares pins with other peripherals, requiring proper MPC configuration.
What is the maximum A/D conversion speed of R5F52315CDFM#30?
R5F52315CDFM#30 achieves a minimum A/D conversion time of 0.83 µs per channel when ADCLK runs at 54 MHz. This performance is enabled by the S12ADE 12-bit successive approximation register (SAR) ADC with programmable sampling time per channel and supports scan, group, and continuous modes for flexible data acquisition.
Is the TSIP-Lite encryption engine available on R5F52315CDFM#30?
Yes, R5F52315CDFM#30 includes the full TSIP-Lite security subsystem: AES-128/256 engines (GCM/ECB/CBC), true random number generator, hash functions, and key protection circuitry. This implementation satisfies IEC 60730 Class B self-test requirements and is documented in Section 1.1 and Chapter 37 of the R01DS0261EJ0120 datasheet.
Does R5F52315CDFM#30 include an SD host interface (SDHI)?
No, R5F52315CDFM#30 does not include the SD Host Interface. As shown in Table 1.2, SDHI is marked "Not supported" for all RX231 Group 64-pin packages-including PLQP0064KB-C. This omission is consistent across all 64-pin RX231 variants; SDHI is only available in 100-pin TFLGA and LFQFP packages.
What is the operating temperature range for R5F52315CDFM#30?
R5F52315CDFM#30 is rated for −40 to +85°C ambient operation (D version), as specified in Table 1.3 of the datasheet. This grade targets industrial and commercial applications where extended temperature tolerance is required but not extreme (e.g., automotive under-hood). The "D" suffix in the part number explicitly denotes this temperature range.
