It targets industrial HMI, smart sensor nodes, and embedded control systems requiring secure, low-power, mixed-signal processing.

For engineers reviewing the R5F52316CDFP#10 datasheet, R5F52316CDFP#10 pinout, R5F52316CDFP#10 application, or R5F52316CDFP#10 equivalent, this MCU delivers deterministic real-time performance via its 88.56 DMIPS CPU core, hardware FPU, ELC event-driven peripheral coordination, and IEC60730-compliant self-test functions for safety-critical firmware deployment.

Technical Context

The R5F52316CDFP#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip MPU for memory protection. Its clock system supports independent domain clocks (ICLK up to 54 MHz, PCLKA/B/D up to 54/32/54 MHz) and includes USB-dedicated PLL (48 MHz output), sub-clock RTC source, and CAC for frequency accuracy monitoring.

Peripheral integration centers on event-driven operation: ELC enables direct inter-module triggering without CPU intervention, while DTC and DMAC provide autonomous data movement across UART, SPI, I²C, and SDHI interfaces. The CTSU supports up to 24 self-capacitance keys or 144 mutual-capacitance keys with built-in noise immunity algorithms.

FAQ

What is the maximum operating frequency and CPU performance of the R5F52316CDFP#10?

The R5F52316CDFP#10 operates at a maximum frequency of 54 MHz and delivers 88.56 DMIPS performance using the RXv2 32-bit CPU core. Its Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip FPU enable deterministic real-time execution for complex control and signal processing tasks. This performance level is confirmed in Renesas' R01DS0261EJ0120 datasheet Rev.1.20.

Does the R5F52316CDFP#10 include on-chip data flash memory?

No, the R5F52316CDFP#10 does not include on-chip data flash memory. According to Table 1.3 in the R01DS0261EJ0120 datasheet, the "C" revision suffix (as in R5F52316CDFP#10) indicates absence of data flash, whereas "A" variants (e.g., R5F52316ADFP#30) include 8 KB. This affects firmware update strategies and non-volatile parameter storage design.

Which communication interfaces are supported by the R5F52316CDFP#10?

The R5F52316CDFP#10 supports USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), seven SCI channels (including LIN-capable SCIh), one I²C bus interface, one RSPI, one serial sound interface (SSI), and one SD host interface (SDHI). These are fully documented in Section 1.1 of R01DS0261EJ0120 and confirmed for the 100-pin LFQFP package variant.

What is the package type and pin count of the R5F52316CDFP#10?

The R5F52316CDFP#10 uses a 100-pin Low-Profile Quad Flat Package (LFQFP), designated PLQP0100KB-B, with 14 mm × 14 mm body size and 0.5 mm lead pitch. This package is explicitly listed in Table 1.3 of the R01DS0261EJ0120 datasheet for the R5F52316CDFP#30 orderable part, confirming mechanical and thermal compatibility for R5F52316CDFP#10.

Does the R5F52316CDFP#10 support IEC60730 functional safety compliance?

Yes, the R5F52316CDFP#10 includes dedicated hardware features for IEC60730 compliance, including self-diagnostic assistance for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test support via the Data Operation Circuit (DOC), and analog input disconnection detection. These are detailed in the "Useful functions for IEC60730 compliance" section of the R01DS0261EJ0120 datasheet.
