It targets industrial HMI, networked gateways, and secure IoT edge controllers requiring real-time deterministic control and rich peripheral integration.

For engineers reviewing the R5F565N9BGLJ#20 datasheet, R5F565N9BGLJ#20 pinout, R5F565N9BGLJ#20 application, or R5F565N9BGLJ#20 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), 120 MHz system clock with PCLKA/PCLKB domain partitioning, dual 12-bit A/D converters (8+21 channels), 2-channel 12-bit D/A, and IEC60730-compliant safety features including CRCA, IWDT, and register write protection.

Technical Context

The R5F565N9BGLJ#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. Its memory subsystem includes dual-bank 2 Mbyte flash supporting background programming and bank-swapping at reset, plus 640 Kbyte SRAM with no wait states at 120 MHz.

Peripheral timing is rigorously segmented: PCLKA drives high-speed modules (ETHERC, EDMAC, AES, GLCDC, DRW2D) up to 120 MHz; PCLKB governs most other peripherals (SCI, CAN, timers, A/D unit 0) up to 60 MHz; PCLKC/D separately clock A/D units 0/1 at up to 60 MHz; and FCLK clocks flash interface up to 60 MHz - enabling precise power/performance trade-offs.

FAQ

What is the maximum system clock frequency supported by the R5F565N9BGLJ#20?

The R5F565N9BGLJ#20 supports a maximum system clock (ICLK) frequency of 120 MHz. This is achieved using the internal PLL with an external 8–24 MHz crystal or the high-speed on-chip oscillator (HOCO) as reference. At 120 MHz, the CPU delivers 240 DMIPS, and the PCLKA domain (driving ETHERC, GLCDC, DRW2D, etc.) also operates up to 120 MHz, while PCLKB and other domains run up to 60 MHz for optimized power/performance balance.

Does the R5F565N9BGLJ#20 include hardware encryption capabilities?

Yes, the R5F565N9BGLJ#20 integrates the Trusted Secure IP (TSIP) module, which provides hardware-accelerated AES encryption and decryption with key lengths of 128, 192, and 256 bits. TSIP supports secure key storage, random number generation, and cryptographic operations without exposing keys to software - a critical feature for secure boot, firmware updates, and data-at-rest protection in the R5F565N9BGLJ#20.

What package type and dimensions does the R5F565N9BGLJ#20 use?

The R5F565N9BGLJ#20 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm ball pitch. It is RoHS-compliant and lead-free. This package provides 136 general-purpose I/O pins with 5-V tolerance on 19 pins, supporting high-density industrial PCB layouts while maintaining signal integrity for high-speed interfaces like Ethernet and QSPI.

How does the R5F565N9BGLJ#20 support IEC60730 Class B compliance?

The R5F565N9BGLJ#20 includes multiple hardware features for IEC60730 Class B compliance: an independent watchdog timer (IWDT) with configurable window function, CRC calculator (CRCA) for memory/data integrity, oscillation-stop detection, self-diagnostic A/D converter, and register write protection. These features - documented in Renesas Application Note R01AN3819EJ0100 - enable systematic fault detection and recovery without software overhead, directly supporting safety-critical firmware validation for the R5F565N9BGLJ#20.

Can the R5F565N9BGLJ#20 operate the real-time clock (RTC) during main power loss?

Yes, the R5F565N9BGLJ#20 supports RTC battery backup via the VBATT pin. When main VCC drops, the RTC continues timekeeping using power from an external coin-cell or supercapacitor connected to VBATT. The RTC retains calendar/clock functions, alarm interrupts, and time-capture capability in deep software standby mode - ensuring uninterrupted time-stamping for logging and scheduling even during system power-down events involving the R5F565N9BGLJ#20.
