It targets industrial motor control and embedded HMI applications requiring deterministic real-time performance and functional safety support.

For engineers reviewing the R5F56307CDFP#V0 datasheet, R5F56307CDFP#V0 pinout, R5F56307CDFP#V0 application, or R5F56307CDFP#V0 equivalent, key selection criteria include its 100-MHz operation with 165 DMIPS, integrated CAN+USB dual-interface capability, IEC 60730-compliant self-test features (CRC, IWDT, A/D self-diagnosis), and -40°C to +85°C temperature grade.

Technical Context

The R5F56307CDFP#V0 implements the RXv1 CPU core with 5-stage CISC Harvard pipeline, variable-length instructions, and memory protection unit (MPU). Its clock system supports external crystal (4–16 MHz) with PLL up to 100 MHz, plus independent LOCO (125 kHz) and HOCO (50 MHz) oscillators for low-power and watchdog timing.

Peripheral integration includes three CAN channels (32 mailboxes each), 13 SCI interfaces with flexible modes (asynchronous, SPI, I²C, LIN), four RSPI channels, four I²C bus interfaces (one FM+), and dual 16-bit timer units (MTU2 and TPU) supporting PWM, input capture, and phase counting - all synchronized to programmable PCLK up to 50 MHz.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F56307CDFP#V0?

The R5F56307CDFP#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance. This is achieved through its optimized RXv1 CPU core with 5-stage pipeline and hardware floating-point unit, enabling deterministic execution of real-time control loops without software emulation overhead. The R5F56307CDFP#V0 sustains this performance across its full operating temperature range (-40°C to +85°C).

Does the R5F56307CDFP#V0 include a CAN interface?

No, the R5F56307CDFP#V0 does not include a CAN interface. The 'C' in the part number suffix indicates CAN omission, distinguishing it from the 'D' variant (e.g., R5F56307DDFP#V0) which integrates three ISO 11898-1 compliant CAN channels. This makes the R5F56307CDFP#V0 suitable for applications where CAN is unnecessary, reducing cost and simplifying EMC design while retaining USB, SCI, and I²C connectivity.

What package type and pin count does the R5F56307CDFP#V0 use?

The R5F56307CDFP#V0 uses the PLQP0100KB-A package: a 100-pin LQFP with 14 × 14 mm body size and 0.5 mm pitch. It provides 148 general-purpose I/O pins (including dedicated function pins), with 54 pins rated for 5-V tolerance. This package balances board space, thermal performance, and routing simplicity for mid-complexity industrial control designs.

How much on-chip memory does the R5F56307CDFP#V0 have?

The R5F56307CDFP#V0 integrates 384 KB of on-chip flash memory (executed at 100 MHz with zero wait states), 64 KB of SRAM (also zero-wait), and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. The data flash supports background operation (BGO), allowing concurrent program/erase and CPU execution - essential for robust firmware updates and parameter logging in the R5F56307CDFP#V0.

What functional safety features does the R5F56307CDFP#V0 support for IEC 60730 compliance?

The R5F56307CDFP#V0 includes multiple hardware features for IEC 60730 Class B compliance: oscillation-stop detection for main/sub clocks, dedicated independent watchdog timer (IWDT) with internal oscillator, CRC calculator supporting three polynomials, and self-diagnostic capability for the 10-bit A/D converter. These features are documented in Renesas' hardware manual and reduce software validation burden when implementing safety-critical functions in the R5F56307CDFP#V0.
