Renesas R5F565N7BGLJ#20

Overview

R5F565N7BGLJ#20 from Renesas is a 120-MHz 32-bit RXv2 MCU with single-precision IEEE-754 FPU, 240 DMIPS performance, 2 MB on-chip code flash (dual-bank), 640 KB SRAM, Ethernet MAC, CAN, SD host/slave, QSPI, and hardware AES/TSIP encryption. It targets industrial HMI, networked gateways, and secure edge controllers requiring real-time deterministic execution, rich peripheral integration, and IEC 60730 compliance.

For engineers reviewing the R5F565N7BGLJ#20 datasheet, R5F565N7BGLJ#20 pinout, R5F565N7BGLJ#20 application, or R5F565N7BGLJ#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 120 MHz system clock with PCLKA/PCLKB domain separation, dual-bank flash for safe firmware updates, integrated GLCDC + DRW2D for graphics acceleration, and TSIP-based secure boot capability.

Technical Context

The R5F565N7BGLJ#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code density and fast interrupt response. Its memory subsystem includes dual-bank 2 MB flash (with background programming), 640 KB SRAM (no wait states at 120 MHz), and 8 KB standby RAM backed by VBATT.

Peripheral timing is rigorously partitioned: 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 TPU, MTU3, SCI, and A/D converters; PCLKC/PCLKD (up to 60 MHz) feed S12AD units independently. This enables concurrent high-speed communication, graphics rendering, and analog acquisition without resource contention.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F565N7BGLJ#20?

The R5F565N7BGLJ#20 operates at a maximum frequency of 120 MHz using the 32-bit RXv2 CPU core. This core features a 5-stage pipeline, Harvard architecture, variable-length instructions, and delivers 240 DMIPS performance. It includes single-precision IEEE-754 floating-point support, two multiply-and-accumulate units, and a 32-bit multiplier with one-cycle execution for critical math operations-making R5F565N7BGLJ#20 suitable for real-time industrial control and signal processing tasks.

Does the R5F565N7BGLJ#20 support secure boot and cryptographic acceleration?

Yes, the R5F565N7BGLJ#20 integrates Trusted Secure IP (TSIP) for hardware-accelerated cryptographic operations including AES-128/192/256 encryption/decryption, secure key storage, and secure boot verification. It also includes a CRC calculator supporting multiple polynomials for data integrity checks, register write protection to prevent accidental overwrites of safety-critical registers, and oscillation-stop detection-all contributing to IEC 60730 Class B compliance. These features ensure R5F565N7BGLJ#20 meets stringent security requirements for industrial and medical edge devices.

What display and graphics capabilities does the R5F565N7BGLJ#20 provide?

The R5F565N7BGLJ#20 includes a dedicated Graphic-LCD Controller (GLCDC) supporting 3-plane overlay (background, graphic 1, graphic 2) and multiple pixel formats (32/16/8/4/1 bpp). It also integrates a 2D Drawing Engine (DRW2D) capable of vector drawing (lines, triangles, circles), bit blitting with scaling and rotation, and texture mapping. Together, these accelerators offload CPU-intensive rendering tasks-enabling smooth GUIs on resolutions up to WVGA. This makes R5F565N7BGLJ#20 ideal for industrial HMIs where responsive touch interfaces and local visualization are essential.

How many communication interfaces does the R5F565N7BGLJ#20 support, and which are most relevant for industrial networking?

The R5F565N7BGLJ#20 supports Ethernet MAC (10/100 Mbps MII/RMII), two CAN 2.0B channels (32 mailboxes each), three RSPI, one QSPI, three I2C (up to 1 Mbps), 13 SCI channels (including LIN-capable SCIh), SD host/slave, and MMCIF interfaces. For industrial networking, the combination of Ethernet for backbone connectivity and dual CAN for fieldbus interoperability is especially valuable-allowing R5F565N7BGLJ#20 to serve as a protocol gateway between higher-level IT systems and legacy factory-floor devices without external bridge ICs.

What is the memory configuration of the R5F565N7BGLJ#20, and how does dual-bank flash benefit firmware updates?

The R5F565N7BGLJ#20 includes 2 MB of on-chip code flash memory organized in a dual-bank structure, 640 KB of SRAM (256 KB main + 384 KB expansion), and 8 KB of battery-backed standby RAM. The dual-bank flash allows background programming: while one bank executes active firmware, the other can be erased and reprogrammed-enabling truly seamless over-the-air (OTA) or field firmware updates with zero system downtime. This architecture is critical for R5F565N7BGLJ#20 deployments in unattended industrial equipment where maintenance windows are impractical.
