Overview
R5F52316AGFP#50 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, 24-channel 12-bit ADC (0.83 µs conversion), dual 12-bit DAC, RTC with battery backup, and capacitive touch sensing - deployed in industrial HMI and smart sensor edge nodes.
For engineers reviewing the R5F52316AGFP#50 datasheet, R5F52316AGFP#50 pinout, R5F52316AGFP#50 application, or R5F52316AGFP#50 equivalent, key selection criteria include its 100-pin LFQFP package, −40 to +105°C temperature grade (G version), absence of SDHI and CAN modules per package mapping, and compatibility with Renesas' RX231 Group toolchain and E2 studio IDE.
Technical Context
The R5F52316AGFP#50 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code and deterministic interrupt latency. It integrates an on-chip FPU compliant with IEEE 754 and a 32-bit multiplier/divider for real-time signal processing tasks.
Its peripheral set includes six 16-bit TPU channels, six 16-bit MTU2 channels, four DMAC channels, ELC for event-driven low-power operation, and TSIP-Lite for secure AES-GCM/ECB/CBC encryption - all clocked from configurable PCLK domains (ICLK up to 54 MHz, PCLKA/B/D up to 54/32/54 MHz).

The R5F52316AGFP#50 operates at a maximum system clock frequency of 54 MHz, delivering 88.56 DMIPS performance using the RXv2 32-bit CPU core. Its 5-stage pipeline, variable-length instruction set, and on-chip FPU enable deterministic real-time execution - verified in Renesas' R01DS0261EJ0120 datasheet Section 1.1. The R5F52316AGFP#50 sustains this speed across its full 1.8–5.5 V supply range and −40 to +105°C operating temperature.
Does the R5F52316AGFP#50 support USB 2.0 and CAN interfaces?
The R5F52316AGFP#50 integrates a full-featured USB 2.0 host/function/OTG module supporting 12 Mbps full-speed operation, isochronous transfers, and BC1.2 battery charging - confirmed in Section 1.1 of the datasheet. However, it does not include the RSCAN CAN module; Table 1.2 explicitly lists CAN as "Not supported" for 100-pin RX231 Group devices in LFQFP packages like the R5F52316AGFP#50.
What memory resources are available on the R5F52316AGFP#50?
The R5F52316AGFP#50 contains 256 KB of on-chip flash memory (with no-wait access up to 32 MHz), 32 KB of SRAM (no-wait at 54 MHz), and 8 KB of data flash rated for 1,000,000 program/erase cycles. All memory blocks support background operation and are accessible via the RXv2 core's 4-Gbyte linear address space - details are specified in Table 1.1 and Section 1.2 of the R01DS0261EJ0120 datasheet for the R5F52316AGFP#50.
Is the R5F52316AGFP#50 qualified for extended temperature operation?
Yes, the R5F52316AGFP#50 is a G-grade device rated for −40 to +105°C operation, as indicated by the "G" in its part number and confirmed in Table 1.4 (G Version list) of the R01DS0261EJ0120 datasheet. This qualification makes it suitable for under-hood automotive ancillaries, industrial drives, and outdoor infrastructure where ambient temperatures exceed standard commercial grade limits.
What security features does the R5F52316AGFP#50 provide?
The R5F52316AGFP#50 integrates TSIP-Lite - Renesas' Trusted Secure IP subsystem - supporting AES-128/256 encryption in ECB, CBC, GCM, and CMAC modes, plus SHA-256 hash and a true random number generator. Key management is hardware-enforced to prevent extraction, and the module is designed to meet IEC 60730 Class B safety requirements - all documented in Section 1.1 and the Security Functions chapter of the R01DS0261EJ0120 datasheet for the R5F52316AGFP#50.
