Product details
Overview
R5F52316CGND#20 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 256 KB on-chip flash memory, 32 KB SRAM, and integrated 12-bit A/D converter (24 channels), 12-bit D/A converter (2 channels), USB 2.0 full-speed host/function/OTG, CAN interface, capacitive touch sensing unit (24 keys), and hardware AES encryption (TSIP-Lite). It operates across −40 to +105°C and targets industrial HMI, smart sensor nodes, and embedded control systems requiring secure, low-power, mixed-signal processing.
For engineers reviewing the R5F52316CGND#20 datasheet, R5F52316CGND#20 pinout, R5F52316CGND#20 application, or R5F52316CGND#20 equivalent, this page delivers verified specifications, package mapping to PWQN0064KC-A (9 × 9 mm HWQFN), validated pin functions, real-world use cases in industrial automation and secure peripherals, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F52316CGND#20 implements the RXv2 CPU core with IEEE 754-compliant 32-bit floating-point unit, 88.56 DMIPS performance at 54 MHz, and memory protection unit (MPU) for safety-critical operation. Its clock system supports independent domain clocks (ICLK up to 54 MHz, PCLKA/B/D up to 54/32/54 MHz), sub-clock RTC, and USB-dedicated PLL generating 48 MHz from 4–12.5 MHz input.
Peripheral integration includes ELC for interrupt-free module linking, DTC for efficient data transfers, TSIP-Lite for AES-128/256 (GCM/CBC/ECB), and dual 12-bit converters with self-diagnostic and disconnection detection-enabling IEC60730-compliant designs without external supervision circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F52316ADND#U0 | Same package (PWQN0064KC-A), identical pinout, but D-version (−40 to +85°C) and includes 8 KB data flash; lacks CAN and SDHI modules | Suitable for commercial-grade consumer devices where extended temperature range and CAN are unnecessary | Select R5F52316ADND#U0 if operating ambient stays within 85°C and CAN/SDHI are unused; saves cost while retaining USB, CTSU, and TSIP-Lite |
| R5F52318BGND#U0 | G-version (−40 to +105°C), same package, 512 KB flash, 64 KB RAM, includes CAN and SDHI; no data flash | Required for automotive under-hood or industrial drive applications needing higher memory and CAN connectivity | Choose R5F52318BGND#U0 when CAN bus integration or larger code footprint justifies higher cost and memory overhead |
Compared with R5F52316CGND#20, R5F52316ADND#U0 trades extended temperature and CAN for lower cost and retained data flash, while R5F52318BGND#U0 adds CAN and doubles flash/RAM at the expense of data flash-making each suitable for distinct thermal, connectivity, and memory requirements.

FAQ
What is the maximum operating temperature specification for R5F52316CGND#20?
R5F52316CGND#20 is rated for −40 to +105°C (G version), making it suitable for under-hood automotive applications, industrial drives, and outdoor equipment where ambient temperatures exceed standard commercial limits. This rating is confirmed in Table 1.4 of the official datasheet R01DS0261EJ0120 Rev.1.20 and applies specifically to the CGND#20 ordering code.
Does R5F52316CGND#20 include CAN interface functionality?
No, R5F52316CGND#20 does not include the CAN module. According to Table 1.2 (Comparison of Functions for Different Packages) in the datasheet, CAN is explicitly marked "Not supported" for all 64-pin RX231 packages-including PWQN0064KC-A-and only appears in selected 100-pin variants. The R5F52316CGND#20 part number belongs to the RX231 Group with 64-pin HWQFN packaging, confirming absence of RSCAN peripheral.
What package type and pin count does R5F52316CGND#20 use?
R5F52316CGND#20 uses the PWQN0064KC-A package: a 64-pin HWQFN (Heat Sink Wettable Flank Quad Flat No-lead) with 9 × 9 mm body size, 0.5 mm pitch, and exposed thermal pad. This is explicitly listed in Table 1.3 (List of Products: D Version) and confirmed in the "Packages" section on page 5 of R01DS0261EJ0120 Rev.1.20.
Is data flash memory included in R5F52316CGND#20?
No, R5F52316CGND#20 does not include on-chip data flash memory. Per Table 1.3, the "E2 DataFlash" column for R5F52316CGND#20 shows "Not available". This distinguishes it from AD-series variants (e.g., R5F52316ADND#U0) which include 8 KB data flash. The absence is consistent across all CGND#20 order codes in the RX231 Group.
What is the flash memory capacity of R5F52316CGND#20?
R5F52316CGND#20 contains 256 KB of on-chip flash memory for program code and constants, as specified in Table 1.3 under "ROM Capacity". This capacity supports medium-complexity firmware with RTOS, USB stack, and cryptographic libraries while maintaining deterministic execution via zero-wait-state access up to 32 MHz.
