For engineers reviewing the R5F565N9FDFB#10 datasheet, R5F565N9FDFB#10 pinout, R5F565N9FDFB#10 application, or R5F565N9FDFB#10 equivalent, key selection criteria include dual-bank flash for safe firmware updates, 136 GPIOs with 5-V tolerance, real-time clock with battery backup, IEEE 802.3-compliant Ethernet PHY integration, and TSIP-based secure boot support.

Technical Context

The R5F565N9FDFB#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code density and deterministic interrupt latency. It integrates a single-precision IEEE-754 FPU, two MAC units, and a 32-bit multiplier with one-cycle execution at 120 MHz.

Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL to generate ICLK up to 120 MHz, PCLKA up to 120 MHz (for ETHERC, GLCDC, DRW2D), and PCLKB up to 60 MHz (for most peripherals including S12AD units). The device supports four low-power modes and battery-backed RTC operation via VBATT.

FAQ

What is the maximum operating frequency and core architecture of the R5F565N9FDFB#10?

The R5F565N9FDFB#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instruction set. It delivers 240 DMIPS performance and includes a single-precision IEEE-754 floating-point unit, two MAC units, and a 32-bit multiplier with one-cycle execution. This architecture enables deterministic real-time response and compact code density critical for R5F565N9FDFB#10-based industrial control systems.

Does the R5F565N9FDFB#10 include an integrated Ethernet PHY?

Yes, the R5F565N9FDFB#10 integrates a full IEEE 802.3-compliant Ethernet PHY supporting both MII and RMII interfaces at 10/100 Mbps. This eliminates the need for an external PHY IC, reducing bill-of-materials cost and PCB space. The PHY supports Magic Packet™ wake-on-LAN, flow control per IEEE 802.3x, and is directly connected to the on-chip ETHERC and EDMAC modules - enabling efficient packet handling in R5F565N9FDFB#10-based networked gateways and controllers.

What security features does the R5F565N9FDFB#10 provide for secure firmware updates?

The R5F565N9FDFB#10 provides hardware-enforced security for firmware updates via its Trusted Secure IP (TSIP) module, which accelerates AES-128/192/256 encryption and supports secure key storage. Combined with dual-bank flash memory, it enables authenticated, encrypted, and atomic firmware swaps without interrupting operation. The MPU enforces memory isolation between bootloader and application, while register write protection prevents accidental corruption of critical control registers - all essential for R5F565N9FDFB#10 deployments in regulated environments.

How many analog-to-digital converter channels does the R5F565N9FDFB#10 support, and what resolution options are available?

The R5F565N9FDFB#10 integrates two independent 12-bit A/D converters: S12AD unit 0 with 8 input channels and unit 1 with 21 input channels. Each unit supports selectable resolution of 8-, 10-, or 12-bit conversion, with minimum conversion times of 0.42 µs (8-bit), 0.45 µs (10-bit), and 0.48 µs (12-bit) per channel. Both units include self-diagnostic functions, analog input disconnection detection, and flexible trigger sources - making them suitable for precision sensing in R5F565N9FDFB#10-based medical and industrial data loggers.

What is the package type and pin count of the R5F565N9FDFB#10, and which I/O features are supported?

The R5F565N9FDFB#10 uses a 176-ball LFBGA package (PLQP0176KB-A, 24 × 24 mm, 0.5-mm pitch) with 136 general-purpose I/O pins. These pins support 5-V tolerance, programmable pull-up resistors, open-drain output, and switchable drive strength. Dedicated pins include ETH_MDC/MDIO, CAN0_TX/RX, SD0_CMD/CLK/DAT, and VBATT for battery-backed RTC - enabling direct interfacing with industrial sensors, displays, and communication peripherals in R5F565N9FDFB#10 designs.
