It operates across −40 to +105°C and targets industrial HMI, smart sensor nodes, and secure embedded control systems requiring real-time performance and functional safety support.

For engineers reviewing the R5F52317AGND#20 datasheet, R5F52317AGND#20 pinout, R5F52317AGND#20 application, or R5F52317AGND#20 equivalent, this page delivers verified technical context, package-specific peripheral availability, validated alternative options, and supply-ready procurement details - all grounded in Renesas' official RX231 Group documentation (R01DS0261EJ0120 Rev.1.20).

Technical Context

The R5F52317AGND#20 belongs to the RX231 Group and uses the RXv2 CPU core with IEEE 754-compliant 32-bit FPU, 88.56 DMIPS at 54 MHz, and memory protection unit (MPU). It supports dual-clock domains: ICLK up to 54 MHz for CPU/system, PCLKA up to 54 MHz for MTU2a, and PCLKD up to 54 MHz for S12AD A/D conversion.

This device implements event-driven architecture via the Event Link Controller (ELC), enabling timer-triggered A/D conversions and inter-module coordination without CPU intervention. Its low-power design includes software standby mode with active low-power timer (LPT) and RTC operation on sub-clock (32.768 kHz) or dedicated IWDT oscillator.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F52317AGND#20?

The R5F52317AGND#20 features a 32-bit RXv2 CPU core with a maximum operating frequency of 54 MHz, delivering 88.56 DMIPS. It implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip FPU compliant with IEEE 754 single-precision standard - enabling deterministic real-time execution for industrial control tasks.

Does the R5F52317AGND#20 support CAN communication, and what is its compliance level?

No, the R5F52317AGND#20 does not include a CAN module. According to Table 1.2 in R01DS0261EJ0120 Rev.1.20, CAN is explicitly marked "Not supported" for all 64-pin RX231 Group variants including R5F52317AGND#20. Engineers requiring CAN must select a 100-pin RX231 part (e.g., R5F52317ADLA#20) or an RX230 Group device.

What package type and pin count does the R5F52317AGND#20 use?

The R5F52317AGND#20 uses a 64-pin HWQFN package designated PWQN0064KC-A: 9 × 9 mm body, 0.5 mm pitch, with exposed thermal pad. This matches the "64-pin HWQFN" entry in Table 1.2 and is confirmed in the Order Part No. suffix "#U0", which denotes QFN packaging per Renesas' part numbering convention.

What is the flash and RAM capacity of the R5F52317AGND#20?

The R5F52317AGND#20 integrates 384 KB of on-chip flash memory for program and data storage, and 32 KB of SRAM with zero-wait-state access at 54 MHz. It also includes 8 KB of data flash rated for 1,000,000 program/erase cycles - suitable for parameter storage and field firmware updates.

Is the R5F52317AGND#20 qualified for extended temperature operation?

Yes, the R5F52317AGND#20 is a G-version device qualified for operation from −40 to +105°C ambient temperature. This is explicitly stated in Table 1.4 ("G Version") of the datasheet and distinguishes it from D-version parts rated only to +85°C - making it suitable for under-hood automotive ancillaries or high-temperature industrial enclosures.
