Renesas R5F52316CGFL#30

Overview

R5F52316CGFL#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 256 KB on-chip flash, 32 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 R5F52316CGFL#30 datasheet, R5F52316CGFL#30 pinout, R5F52316CGFL#30 application, or R5F52316CGFL#30 equivalent, key selection considerations include its 48-pin LFQFP package (7 × 7 mm, 0.5 mm pitch), −40 to +105°C G-grade temperature rating, absence of SDHI and CAN modules (per Table 1.4), and support for ELC-triggered peripheral coordination without CPU wake-up.

Technical Context

The R5F52316CGFL#30 belongs to the RX231 Group G-version (−40 to +105°C), implementing the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU. It executes at 54 MHz using a PLL-driven system clock (ICLK), while peripheral clocks (PCLKA/B/D) are independently configurable up to 54 MHz, 32 MHz, and 54 MHz respectively - enabling precise timing isolation for ADC, timers, and USB.

Its low-power design includes three modes (sleep, deep sleep, software standby), a sub-clock-driven LPT timer active during standby, and voltage detection circuits (LVD0–LVD2) with programmable thresholds. The ELC enables direct event routing between 61 signal sources and peripherals (e.g., TPU→ADC trigger), eliminating interrupt latency and CPU involvement in time-critical sequences.

FAQ

What is the maximum operating frequency and CPU performance of the R5F52316CGFL#30?

The R5F52316CGFL#30 operates at a maximum frequency of 54 MHz using its RXv2 core, delivering 88.56 DMIPS. Its performance includes single-cycle instruction execution, 32-bit multiply-accumulate, and IEEE 754-compliant floating-point operations - enabling real-time control and signal processing in compact industrial systems. This performance level is sustained across its full −40 to +105°C operating range.

Does the R5F52316CGFL#30 include CAN or SD host interface functionality?

No, the R5F52316CGFL#30 does not include CAN or SD host interface (SDHI) modules. As confirmed in Table 1.4 of the datasheet, this G-grade 48-pin variant omits both RSCAN and SDHI peripherals. Engineers requiring CAN must select an RX230 Group part (e.g., R5F52306ADFP#30) or higher-pin-count RX231 variants like R5F52318AGFP#30.

What package type and pin count does the R5F52316CGFL#30 use?

The R5F52316CGFL#30 uses a 48-pin LFQFP package designated PLQP0048KB-B, measuring 7 × 7 mm with 0.5 mm pitch. It features an exposed thermal pad (non-electrical), four ground pins, dual VCC pins, and dedicated RTC power rails - optimized for thermal dissipation and noise isolation in dense industrial PCB layouts.

How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F52316CGFL#30?

The ELC in the R5F52316CGFL#30 enables direct hardware-level triggering between 61 event sources and peripherals - for example, a TPU timer overflow can initiate an ADC conversion without CPU intervention or interrupt latency. This reduces jitter, lowers power consumption by avoiding wake-ups, and simplifies deterministic timing in motor control or sensor sampling loops.

Is hardware encryption supported on the R5F52316CGFL#30, and what algorithms are available?

Yes, the R5F52316CGFL#30 integrates TSIP-Lite, providing hardware-accelerated AES-128 and AES-256 encryption in ECB, CBC, GCM, CMAC, XTS, CTR, and GCTR modes. It also includes a true random number generator and secure key management - enabling secure boot, firmware authentication, and encrypted data storage without software-only crypto overhead.
