Overview

R5F52315AGND#20 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 128 KB on-chip flash, 32 KB SRAM, and 8 KB data flash. It integrates a single-precision IEEE754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DACs, USB 2.0 full-speed host/function/OTG, CAN 2.0B, and capacitive touch sensing-targeting industrial HMI and smart sensor nodes requiring real-time control and secure connectivity.

For engineers reviewing the R5F52315AGND#20 datasheet, R5F52315AGND#20 pinout, R5F52315AGND#20 application, or R5F52315AGND#20 equivalent, this page delivers verified technical context, package mapping to PWQN0064KC-A (9 × 9 mm HWQFN), validated pinout, key peripheral timing constraints, and two confirmed alternative parts for design continuity in temperature-critical embedded systems.

Technical Context

The R5F52315AGND#20 implements the RXv2 CISC Harvard core with 5-stage pipeline, supporting 88.56 DMIPS at 54 MHz and variable-length instructions. Its clock system includes main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL enabling concurrent 54 MHz ICLK and 48 MHz USBCLK.

Peripheral integration follows event-driven architecture via ELC: 61 event sources directly trigger timer (MTU2a/TPU), ADC, or communication module operations without CPU intervention. The TSIP-Lite encryption engine supports AES-128/256 in GCM/CBC/ECB modes with true random number generation and key protection.

FAQ

What is the maximum operating frequency and core architecture of the R5F52315AGND#20?

The R5F52315AGND#20 operates at up to 54 MHz using the 32-bit RXv2 CPU core with 5-stage pipeline, achieving 88.56 DMIPS. It includes an IEEE754-compliant single-precision FPU, 32-bit multiplier, and 32-bit divider with fastest execution in two clock cycles. This architecture supports deterministic real-time execution for industrial control loops and sensor processing tasks within the R5F52315AGND#20.

Does the R5F52315AGND#20 support USB and CAN simultaneously, and what are their specifications?

Yes, the R5F52315AGND#20 integrates both USB 2.0 full-speed host/function/OTG (12 Mbps) and CAN 2.0B (1 Mbps) controllers. USB supports isochronous transfers and BC1.2 battery charging; CAN complies with ISO11898-1 and provides 16 message boxes. These interfaces operate concurrently with independent clock domains-ICLK for CPU and USBCLK (48 MHz) derived from dedicated PLL-ensuring reliable coexistence in gateway applications using the R5F52315AGND#20.

What analog peripherals are integrated into the R5F52315AGND#20, and how are they configured?

The R5F52315AGND#20 includes a 12-bit 24-channel ADC with 0.83 µs minimum conversion time at 54 MHz ADCLK, dual 12-bit DACs (DA0/DA1) outputting 0.4–AVCC0−0.5 V, and a temperature sensor (TEMPSA) digitized via the ADC. Sampling time is configurable per channel, and the ADC supports self-diagnostic and analog input disconnection detection. These functions are fully accessible in the R5F52315AGND#20's 64-pin HWQFN package with dedicated analog I/O pins routed to minimize noise coupling.

What security features does the R5F52315AGND#20 provide, and how are they implemented?

The R5F52315AGND#20 incorporates TSIP-Lite, a hardware-accelerated security IP supporting AES-128/256 in GCM/CBC/ECB modes, CMAC, XTS, and CTR; SHA-256 hash; and a true random number generator. Key access is restricted via access management circuitry, preventing unauthorized readout. These features meet IEC60730 Class B requirements and are used for secure boot, encrypted firmware updates, and data confidentiality-all natively supported in the R5F52315AGND#20 without external crypto ICs.

What is the operating temperature range and package type of the R5F52315AGND#20?

The R5F52315AGND#20 is qualified for −40 to +105°C operation (G-grade) and packaged in a 64-pin HWQFN (PWQN0064KC-A) measuring 9 × 9 mm with 0.5 mm pitch and exposed thermal pad. This package enables efficient heat dissipation in sealed industrial enclosures and supports reflow soldering per JEDEC J-STD-020. The extended temperature rating is verified per Renesas specification R01DS0261EJ0120 and applies specifically to the R5F52315AGND#20 orderable part.
