For engineers reviewing the R5F565N4AGLJ#20 datasheet, R5F565N4AGLJ#20 pinout, R5F565N4AGLJ#20 application, or R5F565N4AGLJ#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 120 MHz system clock with PCLKA/PCLKB domain partitioning, dual-bank flash for safe OTA updates, TSIP-based AES-128/192/256 encryption, and IEC60730-compliant safety features including CRC, IWDT, and self-diagnostic A/D.

Technical Context

The R5F565N4AGLJ#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU-enforced memory protection across eight configurable regions. It supports little-endian or big-endian data arrangement and executes 32×32→64-bit multiply and 32÷32→32-bit divide in one or two cycles respectively.

Clock domains are strictly segmented: ICLK up to 120 MHz drives CPU and bus masters; PCLKA (up to 120 MHz) clocks ETHERC, EDMAC, AES, GLCDC, and DRW2D; PCLKB (up to 60 MHz) serves MTU3, RSPI, SCIi, S12AD unit 0, and most peripherals; PCLKC/PCLKD (up to 60 MHz) drive S12AD units separately for independent analog sampling control.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F565N4AGLJ#20?

The R5F565N4AGLJ#20 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core with 5-stage pipeline, variable-length instructions, and Harvard architecture. It delivers 240 DMIPS performance and includes single-precision IEEE-754 floating-point unit, 32×32 multiplier, and 32÷32 divider - all confirmed in the official R01DS0276EJ0240 datasheet Rev.2.40. This architecture enables deterministic real-time execution for industrial control loops.

Does the R5F565N4AGLJ#20 support secure firmware updates and cryptographic operations?

Yes, the R5F565N4AGLJ#20 integrates Trusted Secure IP (TSIP) supporting AES-128, AES-192, and AES-256 encryption/decryption in hardware, along with a CRC calculator (CRCA) for data integrity verification. Its dual-bank flash architecture allows background programming of the inactive bank while the active bank runs - enabling secure, zero-downtime firmware updates. These features are explicitly documented in the R01DS0276EJ0240 datasheet sections on security and flash memory.

What graphics and display capabilities does the R5F565N4AGLJ#20 provide?

The R5F565N4AGLJ#20 includes a Graphic-LCD Controller (GLCDC) supporting 3-plane overlay (background, graphic 1, graphic 2) and a 2D Drawing Engine (DRW2D) with vector drawing, bit blitting, texture mapping, and display list mode. It supports 32-/16-/8-bit pixel formats and CLUT-based color lookup. These accelerators offload GUI rendering from the CPU - a capability verified in the "Graphics & Imaging" section of the R01DS0276EJ0240 datasheet and confirmed by Renesas' RX65N Group application notes.

Which communication interfaces are integrated into the R5F565N4AGLJ#20?

The R5F565N4AGLJ#20 integrates Ethernet MAC (10/100 Mbps MII/RMII), two CAN 2.0B channels (32 mailboxes each), three RSPI, one QSPI, three I2C (RIIC), 13 SCI (including FIFO-equipped SCIi), SD host/slave (SDHI/SDSI), and MMCIF interfaces. All are detailed in Table 1.1 of the R01DS0276EJ0240 datasheet Rev.2.40. This comprehensive set enables simultaneous multi-protocol connectivity in gateways and edge nodes without external bridge ICs.

What is the package type and thermal rating of the R5F565N4AGLJ#20?

The R5F565N4AGLJ#20 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm body, 0.5-mm pitch, and G-version industrial temperature range of –40°C to +105°C. This package supports high I/O density (136 GPIOs) with 5-V tolerant pins and is specified in the "Package Dimensions" section of the R01DS0276EJ0240 datasheet Rev.2.40. The thermal rating confirms suitability for enclosed industrial enclosures without forced cooling.
