Product details
Overview
R5F52318BDFP#30 from Renesas is a 32-bit RXv2 core MCU operating at up to 54 MHz (88.56 DMIPS), featuring 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, integrated FPU (IEEE 754 single-precision), and hardware encryption (TSIP-Lite AES-128/256). It supports USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), 24-channel 12-bit ADC (0.83 µs conversion), dual 12-bit DAC, RTC with battery backup, and capacitive touch sensing (24 keys) - deployed in industrial HMI and smart sensor edge nodes.
For engineers reviewing the R5F52318BDFP#30 datasheet, R5F52318BDFP#30 pinout, R5F52318BDFP#30 application, or R5F52318BDFP#30 equivalent, key selection criteria include its 100-pin LFQFP package (PLQP0100KB-B), 54 MHz system clock with independent 48 MHz USB PLL, support for IEC60730 safety diagnostics, and availability of SDHI, CAN, and USB in this specific variant.
Technical Context
The R5F52318BDFP#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code and deterministic interrupt latency. It integrates an on-chip FPU compliant to IEEE 754 and a 32-bit divider with two-cycle minimum execution.
Its peripheral subsystem includes ELC (Event Link Controller) for interrupt-free module chaining, DTC (Data Transfer Controller) with chain transfer, and MPC (Multi-function Pin Controller) for flexible I/O mapping. The MCU supports three low-power modes (sleep, deep sleep, software standby), with LPT running during standby using sub-clock or IWDT oscillator.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F52318BDFP#30?
The R5F52318BDFP#30 operates at a maximum frequency of 54 MHz and delivers 88.56 DMIPS. This performance stems from its RXv2 CPU core with 5-stage pipeline, variable-length instruction set, and zero-wait-state access to on-chip SRAM at full speed - enabling deterministic real-time response in motor control and protocol stack execution.
Does the R5F52318BDFP#30 support USB 2.0 host and device modes simultaneously?
The R5F52318BDFP#30 integrates a single USB 2.0 host/function/OTG module supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. It does not support simultaneous host and device modes; mode selection is configured at runtime via USB control registers and requires appropriate descriptor handling in firmware.
What security features are included in the R5F52318BDFP#30's TSIP-Lite engine?
The R5F52318BDFP#30 includes TSIP-Lite with AES-128/256 encryption in GCM, CBC, CTR, and XTS modes; CMAC authentication; SHA-256 hash; and a true random number generator (TRNG). Key management is hardware-enforced to prevent unauthorized access, making it suitable for secure boot and encrypted communication in certified devices.
How many analog-to-digital converter channels does the R5F52318BDFP#30 support, and what is the minimum conversion time?
The R5F52318BDFP#30 integrates a 12-bit S12ADE ADC with 24 input channels and a minimum conversion time of 0.83 µs when ADCLK runs at 54 MHz. Each channel supports individually configurable sampling time, and the module provides self-diagnostic and analog input disconnection detection for IEC60730 compliance.
Is the R5F52318BDFP#30 pin-compatible with other RX231 Group MCUs in the same package?
Yes - the R5F52318BDFP#30 uses the 100-pin LFQFP (PLQP0100KB-B) package and shares identical pinout with all other RX231 Group variants in that package, including R5F52318ADFP#30 and R5F52317BDFP#30. Peripheral enablement (e.g., SDHI, CAN) is controlled by firmware and memory configuration, not pin assignment.
