FAQ

What is the maximum system clock frequency supported by the R5F52316ADFM#10?

The R5F52316ADFM#10 supports a maximum system clock (ICLK) frequency of 54 MHz, achievable via its on-chip PLL when driven by a 4–12.5 MHz input source. At this speed, the RXv2 core delivers 88.56 DMIPS and executes most instructions in a single cycle, enabling deterministic real-time response for control loops and communication stacks.

Does the R5F52316ADFM#10 include CAN or SD host interface functionality?

No, the R5F52316ADFM#10 does not include CAN or SD host interface (SDHI) modules. Per Table 1.2 in the official datasheet (R01DS0261EJ0120), these peripherals are explicitly marked "Not supported" for all 64-pin RX231 variants-including R5F52316ADFM#10-while USB 2.0 OTG, SCI, I²C, and RSPI remain fully available.

What security features are implemented in the R5F52316ADFM#10?

The R5F52316ADFM#10 integrates TSIP-Lite, Renesas' Trusted Secure IP module, supporting AES-128/256 encryption in ECB, CBC, and GCM modes, a true random number generator, and secure key management. It also provides hardware-assisted IEC60730 diagnostics for A/D, clock accuracy, IWDT, and RAM, making R5F52316ADFM#10 suitable for certified functional safety applications.

Which package type and footprint does the R5F52316ADFM#10 use?

The R5F52316ADFM#10 uses a 64-pin Low-Profile Quad Flat Package (LFQFP) with designation PLQP0064KB-C: 10 × 10 mm body size, 0.5 mm pin pitch, and standard 0.5 mm lead thickness. This RoHS-compliant, lead-free package is compatible with standard reflow soldering profiles and supports manual inspection and automated optical inspection (AOI).

How many analog-to-digital input channels does the R5F52316ADFM#10 support?

The R5F52316ADFM#10 supports 24 analog input channels for its 12-bit S12ADE A/D converter, with minimum conversion time of 0.83 µs at 54 MHz ADCLK. Each channel allows independent sampling time configuration and supports multiple trigger sources-including software, timers (MTU/TPU), external pins, and ELC events-for flexible signal acquisition timing.
