Renesas R5F52317BDFM#10

Overview

R5F52317BDFM#10 from Renesas is a 32-bit RXv2 microcontroller with 384 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS) with integrated FPU, 24-channel 12-bit ADC, dual 12-bit DAC, USB 2.0 full-speed host/function/OTG, CAN, capacitive touch sensing (24 keys), and TSIP-Lite encryption. It targets industrial HMI, smart sensor nodes, and embedded control requiring real-time performance, secure firmware, and mixed-signal integration.

For engineers reviewing the R5F52317BDFM#10 datasheet, R5F52317BDFM#10 pinout, R5F52317BDFM#10 application, or R5F52317BDFM#10 equivalent, key selection considerations include its 64-pin LFQFP package, −40 to +85°C temperature grade, CAN + USB dual-protocol support, 54 MHz system clock with 48 MHz USB clock, and hardware-accelerated AES-128/256 via TSIP-Lite.

Technical Context

The R5F52317BDFM#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 88.56 DMIPS at 54 MHz while supporting IEEE 754-compliant single-precision FPU and DSP instructions including 32-bit MAC. Its memory subsystem includes 384 KB flash (no wait states ≤32 MHz), 32 KB SRAM, and 8 KB data flash rated for 1M program/erase cycles with background operation (BGO).

Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables 61 event sources-including TPU/MTU timers, ADC triggers, and external pins-to initiate module actions without CPU intervention, while low-power modes (sleep, deep sleep, software standby) and dedicated low-speed oscillators sustain RTC and LPT operation during standby.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F52317BDFM#10?

The R5F52317BDFM#10 operates at a maximum system clock frequency of 54 MHz and delivers 88.56 DMIPS performance. This is achieved using the RXv2 CPU core with 5-stage pipeline and ultra-compact instruction set. The R5F52317BDFM#10 maintains this performance across its full 1.8–5.5 V supply range, with no wait states on SRAM and flash access up to 32 MHz.

Does the R5F52317BDFM#10 support USB and CAN simultaneously?

Yes, the R5F52317BDFM#10 integrates both USB 2.0 full-speed host/function/OTG and a single-channel CAN module compliant with ISO 11898-1. These operate independently-USB uses its dedicated PLL and transceiver, while CAN uses the RSCAN peripheral with 16 message boxes. The R5F52317BDFM#10 can manage concurrent USB device enumeration and CAN frame transmission without resource conflict.

What security features does the R5F52317BDFM#10 provide via TSIP-Lite?

The R5F52317BDFM#10 includes TSIP-Lite, offering hardware-accelerated AES-128/256 encryption in GCM, CBC, ECB, CMAC, and XTS modes; SHA-256 hash; true random number generation; and secure key management that prevents unauthorized readout. These features are certified for IEC 60730 Class B compliance and enable secure boot, firmware authentication, and encrypted data storage within the R5F52317BDFM#10.

How many analog input channels and what ADC resolution does the R5F52317BDFM#10 support?

The R5F52317BDFM#10 integrates a 12-bit successive-approximation A/D converter with 24 dedicated analog input channels (AD00–AD23). Each channel supports individually configurable sampling time, and conversion completes in as little as 0.83 µs when ADCLK runs at 54 MHz. The R5F52317BDFM#10 also provides self-diagnostic and analog input disconnection detection functions for functional safety.

What is the package type and pin count of the R5F52317BDFM#10?

The R5F52317BDFM#10 is housed in a 64-pin Low-Profile Quad Flat Package (LFQFP) designated PLQP0064KB-C, measuring 10 × 10 mm with 0.5 mm pitch and an exposed thermal pad. This package supports 47 general-purpose I/O pins (including 5-V tolerant and open-drain options), matches the pinout of other RX231 Group 64-pin variants, and is compatible with standard reflow soldering profiles.
