It targets industrial HMI, smart sensor nodes, and battery-powered control systems requiring real-time performance, secure firmware updates, and low-power operation down to −40°C to +105°C.

For engineers reviewing the R5F52316CGFM#30 datasheet, R5F52316CGFM#30 pinout, R5F52316CGFM#30 application, or R5F52316CGFM#30 equivalent, this MCU delivers verified 88.56 DMIPS at 54 MHz, IEEE 754-compliant FPU, 1.8–5.5 V single-supply operation, and ELC-driven event-triggered peripheral coordination - critical for deterministic timing in safety-aware embedded designs.

Technical Context

The R5F52316CGFM#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates an on-chip FPU compliant with IEEE 754 single-precision floating-point standard and a 32-bit × 32-bit multiplier with 64-bit result.

Its clock system supports multiple sources: main oscillator (1–20 MHz), sub-clock (32.768 kHz), on-chip high-/low-speed oscillators, PLL (4–12.5 MHz input), and USB-dedicated PLL. System clock runs at up to 54 MHz (ICLK), while peripheral clocks (PCLKA/B/D) are independently configurable up to 54 MHz, 32 MHz, or 54 MHz depending on module - enabling precise power/performance trade-offs.

The R5F52316CGFM#30 operates at a maximum frequency of 54 MHz using the 32-bit RXv2 CPU core. This core features a 5-stage pipeline, CISC Harvard architecture, variable-length instructions, and delivers 88.56 DMIPS. It includes an IEEE 754-compliant single-precision FPU, 32-bit × 32-bit multiplier, and memory protection unit (MPU) - all confirmed in the R01DS0261EJ0120 datasheet Rev.1.20.

Does the R5F52316CGFM#30 support USB and CAN interfaces simultaneously?

Yes, the R5F52316CGFM#30 integrates both USB 2.0 full-speed host/function/OTG (12 Mbps) and a CAN 2.0B module compliant with ISO11898-1 (up to 1 Mbps) on-chip. These operate independently with dedicated clock domains (USB-dedicated PLL and CAN module clock), and both are enabled in the G-version package configuration per Table 1.4 of the datasheet.

What is the operating temperature range and package type for R5F52316CGFM#30?

The R5F52316CGFM#30 is rated for −40°C to +105°C (G-version) and housed in a 64-pin LFQFP package (PLQP0064KB-C), measuring 10 × 10 mm with 0.5 mm pitch. This package is explicitly listed in Table 1.4 of the R01DS0261EJ0120 datasheet for G-version RX231 Group devices including R5F52316CGFM#30.

How much on-chip memory does the R5F52316CGFM#30 include?

The R5F52316CGFM#30 includes 256 KB of on-chip flash memory for program code, 32 KB of SRAM with zero-wait-state access at 54 MHz, and 8 KB of data flash memory rated for 1,000,000 program/erase cycles. All memory specifications are confirmed in Table 1.3 (D/G version listings) and Section 1.1 "Outline of Specifications" of the official datasheet.

Is hardware encryption supported on the R5F52316CGFM#30?

Yes, the R5F52316CGFM#30 integrates TSIP-Lite - Renesas' Trusted Secure IP module - supporting AES-128 and AES-256 encryption in ECB, CBC, GCM, and other modes, plus a true random number generator and secure key management. This is documented in the "Encryption Functions" section (page 1) and Table 1.1 of the R01DS0261EJ0120 datasheet.
