Product details
Overview
R5F52318AGND#00 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 512 KB on-chip flash, 64 KB SRAM, and integrated FPU compliant with IEEE754 single-precision floating-point standard. It supports USB 2.0 full-speed host/function/OTG, CAN 2.0B (1 Mbps), 24-channel 12-bit A/D converter (0.83 µs conversion time), and capacitive touch sensing unit for up to 24 keys - deployed in industrial HMI and smart sensor edge nodes.
For engineers reviewing the R5F52318AGND#00 datasheet, R5F52318AGND#00 pinout, R5F52318AGND#00 application, or R5F52318AGND#00 equivalent, key selection criteria include its 64-pin HWQFN (PWQN0064KC-A) package, −40 to +105°C temperature grade, SDHI interface support, and absence of CAN and RTC modules in this variant - critical for thermal-critical embedded control designs requiring secure boot and TSIP-Lite encryption.
Technical Context
The R5F52318AGND#00 implements the RXv2 CPU core with 5-stage CISC Harvard pipeline, 88.56 DMIPS performance at 54 MHz, and hardware divider (2-cycle min execution). Its memory subsystem includes 512 KB flash (programmable at 1.8 V), 64 KB zero-wait-state SRAM, and 8 KB data flash rated for 1M program/erase cycles with background operation (BGO).
Peripherals are orchestrated via Event Link Controller (ELC) for interrupt-free module triggering and Multi-function Pin Controller (MPC) for flexible I/O assignment. Clocking uses dual PLLs - one for system clock (54 MHz), another USB-dedicated (48 MHz), plus sub-clock (32.768 kHz) for low-power timer and optional RTC (not enabled in this variant per Table 1.2).

FAQ
What is the maximum operating frequency and CPU architecture of the R5F52318AGND#00?
The R5F52318AGND#00 operates at a maximum frequency of 54 MHz using the 32-bit RXv2 CPU core with 5-stage pipeline, achieving 88.56 DMIPS. It includes hardware FPU compliant with IEEE754 single-precision standard, 32-bit multiply-accumulate instructions, and memory protection unit (MPU) - all confirmed in Renesas R01DS0261EJ0120 Rev.1.20 datasheet Section 1.1.
Does the R5F52318AGND#00 support CAN or RTC functionality?
No, the R5F52318AGND#00 does not include CAN or RTC modules. Per Table 1.2 in the R01DS0261EJ0120 datasheet, CAN and RTC are explicitly marked "Not supported" for 64-pin variants in the RX231 Group, including R5F52318AGND#00. This distinguishes it from 100-pin variants like R5F52318AGFP#30 which do support both.
What package type and pin count does the R5F52318AGND#00 use?
The R5F52318AGND#00 uses the PWQN0064KC-A package: a 64-pin HWQFN with 9 × 9 mm body, 0.5 mm pitch, and exposed thermal pad. This is confirmed in Table 1.4 (G Version products) and Figure 1.1 of the R01DS0261EJ0120 datasheet, where "GND" suffix denotes this specific 64-pin HWQFN variant.
What security features are implemented in the R5F52318AGND#00?
The R5F52318AGND#00 integrates TSIP-Lite - Renesas' Trusted Secure IP engine - supporting AES-128/256 in ECB, CBC, and GCM modes, true random number generation, and secure key management. These capabilities are documented in Section 1.1 and Table 1.1 of R01DS0261EJ0120, enabling firmware encryption, secure boot, and anti-tampering in industrial deployments.
Is USB functionality self-powered on the R5F52318AGND#00?
Yes, the R5F52318AGND#00 supports self-powered USB operation: its internal USB regulator generates VBUS from VCC (4.0–5.5 V), eliminating the need for external VBUS supply on the USB_DP/USB_DM lines. This is specified in Section 1.1 "Communication functions" and Table 1.1 of R01DS0261EJ0120 under USB 2.0 host/function module description.
