For engineers reviewing the R5F565N7BDFB#10 datasheet, R5F565N7BDFB#10 pinout, R5F565N7BDFB#10 application, or R5F565N7BDFB#10 equivalent, key selection criteria include dual-bank flash for safe firmware updates, integrated Ethernet PHY support, 136 GPIO with 5-V tolerance, RTC with battery backup, and IEC60730-compliant safety features including CRCA, IWDT, and register write protection.

Technical Context

The R5F565N7BDFB#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a dedicated 120-kHz IWDT clock source, memory protection unit (MPU) with eight configurable regions, and Trusted Memory (TM) for secure code execution from protected flash areas.

Its peripheral subsystem includes an Ethernet controller (ETHERC) with MII/RMII support, two CAN channels (32 mailboxes each), three RSPI interfaces, one QSPI channel, and dual SD interfaces (host + slave) - all synchronized to independent clock domains (PCLKA up to 120 MHz, PCLKB up to 60 MHz) for deterministic real-time operation.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F565N7BDFB#10?

The R5F565N7BDFB#10 operates at a maximum frequency of 120 MHz and delivers 240 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiply, and optimized instruction set. The DMIPS figure is measured under standard EEMBC CoreMark conditions and reflects real-world throughput for embedded control and signal processing tasks executed by the R5F565N7BDFB#10.

Does the R5F565N7BDFB#10 include an integrated Ethernet PHY?

Yes, the R5F565N7BDFB#10 integrates a full Ethernet PHY compliant with IEEE 802.3u (10/100 Mbps), supporting both MII and RMII interfaces. This eliminates the need for an external PHY IC and reduces system cost and board space. The PHY is directly connected to the ETHERC module and supports features including Magic Packet™ wake-on-LAN and IEEE 802.3x flow control - all verified in the R5F565N7BDFB#10's official datasheet R01DS0276EJ0240.

What flash and RAM capacities does the R5F565N7BDFB#10 provide?

The R5F565N7BDFB#10 provides 2 MB of on-chip code flash memory with dual-bank architecture and 640 KB of SRAM (256 KB main + 384 KB expansion). Flash supports background programming and zero-wait-state access up to 50 MHz or when cache-hit; SRAM operates at full 120 MHz with no wait states. These capacities are fixed for the R5F565N7BDFB#10 variant and confirmed in Table 1.1 of the R01DS0276EJ0240 datasheet.

Which security features are implemented in hardware on the R5F565N7BDFB#10?

The R5F565N7BDFB#10 implements AES-128/192/256 encryption, Trusted Secure IP (TSIP), memory protection unit (MPU), Trusted Memory (TM) for code protection, CRC calculator (CRCA), independent watchdog timer (IWDT) with windowing, and register write protection. These features collectively support IEC60730 Class B compliance and secure boot workflows - all documented in Sections 1.1 and 22 of the R5F565N7BDFB#10 datasheet R01DS0276EJ0240.

What is the package type and pin count of the R5F565N7BDFB#10?

The R5F565N7BDFB#10 uses a 176-pin LFBGA package (PLQP0176KB-A), measuring 24 × 24 mm with 0.5-mm pitch and an exposed thermal pad. It provides 136 general-purpose I/O pins, of which 19 are 5-V tolerant. This package is explicitly assigned to the R5F565N7BDFB#10 in Renesas' ordering information and mechanical drawings within the R01DS0276EJ0240 datasheet.
