For engineers reviewing the R5F52316CDFP#30 datasheet, R5F52316CDFP#30 pinout, R5F52316CDFP#30 application, or R5F52316CDFP#30 equivalent, key selection criteria include its 100-pin LFQFP package, integrated TSIP-Lite encryption engine, RTC with battery backup support, and compatibility with IEC60730 Class B safety requirements for embedded control systems.

Technical Context

The R5F52316CDFP#30 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 5-stage CISC Harvard pipeline, and memory protection unit (MPU) - enabling deterministic real-time execution and secure memory partitioning. It supports little-endian data arrangement and variable-length instructions for code density optimization.

Its clock system integrates main (1–20 MHz), sub-clock (32.768 kHz), and USB-dedicated PLL circuits, allowing independent configuration of ICLK (54 MHz), PCLKA/B/D (up to 54 MHz), BCLK (32 MHz), and FCLK (32 MHz). The ELC enables event-triggered peripheral operation without CPU intervention, reducing latency in sensor-to-actuator paths.

FAQ

What is the maximum operating frequency and CPU performance of the R5F52316CDFP#30?

The R5F52316CDFP#30 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS of processing performance using the RXv2 32-bit CPU core. Its 5-stage pipeline, variable-length instruction set, and on-chip FPU enable efficient execution of real-time control algorithms and signal processing tasks without software emulation overhead. This performance level is sustained across the full 1.8–5.5 V supply range.

Does the R5F52316CDFP#30 support USB device, host, and OTG functionality?

Yes, the R5F52316CDFP#30 integrates a full-featured USB 2.0 module supporting device, host, and On-The-Go (OTG) modes at full speed (12 Mbps) and low speed (1.5 Mbps). It includes an internal transceiver and USB-dedicated PLL, eliminating the need for external PHY components. The module supports isochronous transfers and BC1.2 battery charging detection, making it suitable for portable industrial tools and firmware update interfaces.

What security features does the R5F52316CDFP#30 offer for firmware protection?

The R5F52316CDFP#30 incorporates TSIP-Lite - a hardware encryption engine supporting AES-128/256 in GCM, CBC, ECB, and other modes, plus a true random number generator and secure key management. These features enable authenticated and encrypted firmware updates, secure boot verification, and protected data logging. Combined with MPU-based memory isolation and IEC60730 self-test assistance, they form a foundational security stack for industrial edge devices.

How many analog input channels does the 12-bit A/D converter support on the R5F52316CDFP#30?

The R5F52316CDFP#30 integrates the S12ADE 12-bit successive approximation A/D converter with 24 input channels. Each channel supports programmable sampling time, and the converter provides self-diagnostic functions and analog input disconnection detection. Conversion time is as fast as 0.83 µs per channel when ADCLK runs at 54 MHz, making it suitable for high-speed sensor acquisition in motor control and power monitoring applications.

Is the R5F52316CDFP#30 pin-compatible with other members of the RX231 Group in the same package?

Yes, the R5F52316CDFP#30 uses the PLQP0100KB-B 100-pin LFQFP package and shares identical pinout with other RX231 Group devices in that package, including R5F52316ADFP#30, R5F52317ADFP#30, and R5F52318BDFP#30. All share the same signal mapping, power/ground distribution, and peripheral pin assignments - enabling hardware reuse across different flash/RAM configurations and feature sets within the same PCB design.
