For engineers reviewing the R5F565N9FGLJ#20 datasheet, R5F565N9FGLJ#20 pinout, R5F565N9FGLJ#20 application, or R5F565N9FGLJ#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 120 MHz real-time performance with MPU and TSIP security, dual-bank flash for safe firmware updates, and integrated GLCDC + DRW2D for embedded display subsystems.

Technical Context

The R5F565N9FGLJ#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a memory protection unit (MPU) supporting eight configurable regions and Trusted Secure IP (TSIP) for cryptographic key management and secure boot.

Clocking is managed via multiple sources: external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and dedicated IWDT oscillator (120 kHz). Peripheral clocks are independently configurable - PCLKA up to 120 MHz for ETHERC/DRW2D/GLCDC, PCLKB up to 60 MHz for timers and ADC, and ADCLK up to 60 MHz per A/D unit.

FAQ

What is the maximum operating frequency and performance rating of the R5F565N9FGLJ#20?

The R5F565N9FGLJ#20 operates at a maximum system clock frequency of 120 MHz and delivers 240 DMIPS (Dhrystone MIPS) performance. Its RXv2 CPU core supports single-cycle 32×32-bit multiplication and two-cycle 32/32-bit division. The device achieves this performance with zero-wait-state access to 640 KB SRAM and optimized instruction execution through its 5-stage pipeline and variable-length encoding.

Does the R5F565N9FGLJ#20 support secure boot and cryptographic operations?

Yes, the R5F565N9FGLJ#20 integrates Trusted Secure IP (TSIP) for secure boot verification, key wrapping, and resistance to physical and side-channel attacks. It also includes a dedicated AES engine supporting 128-, 192-, and 256-bit keys, plus a CRC calculator with configurable polynomials for 8- and 32-bit data. These features enable IEC 60730 Class B compliance and secure firmware updates without external security ICs.

What display interfaces and graphics capabilities does the R5F565N9FGLJ#20 provide?

The R5F565N9FGLJ#20 integrates a Graphic-LCD Controller (GLCDC) supporting 3-layer overlay (background + 2 graphics planes), multiple pixel formats (32/16 bpp), and direct RGB/ITU-R BT.601 output. It also includes a 2D Drawing Engine (DRW2D) for hardware-accelerated vector drawing and bit blitting. Together, they eliminate the need for external GPU in mid-range HMIs - the R5F565N9FGLJ#20 drives displays up to WVGA resolution with real-time rendering.

Which communication interfaces are integrated into the R5F565N9FGLJ#20 for industrial networking?

The R5F565N9FGLJ#20 integrates Ethernet MAC (10/100 Mbps MII/RMII), two CAN 2.0B channels (32 mailboxes each), three RSPI ports, one QSPI port, three I²C interfaces (up to 1 Mbps), 13 SCI channels (including LIN-capable SCIh), SD host/slave, and MMCIF. This combination enables simultaneous fieldbus (CAN), wired LAN (Ethernet), and storage (SD) connectivity - critical for protocol gateways and edge controllers using the R5F565N9FGLJ#20.

What is the package type and thermal specification of the R5F565N9FGLJ#20?

The R5F565N9FGLJ#20 uses the PLQP0176KB-A package: a 176-pin Low-Profile Quad Flat Package (LFBGA) measuring 24 × 24 mm with 0.5 mm pitch.
