Product details
Overview
R5F5651CHGFB#30 from Renesas is a 32-bit RXv2 microcontroller operating at up to 120 MHz, delivering 240 DMIPS with integrated single-precision IEEE-754 FPU, 2 MB on-chip code flash memory (dual-bank), 640 KB SRAM, and hardware AES-128/192/256 encryption. It integrates Ethernet MAC, CAN 2.0B (2 channels), SD host/slave interfaces, QSPI, GLCDC, DRW2D, and dual 12-bit A/D converters - deployed in industrial HMI, networked gateway, and secure IoT edge controllers.
For engineers reviewing the R5F5651CHGFB#30 datasheet, R5F5651CHGFB#30 pinout, R5F5651CHGFB#30 application, or R5F5651CHGFB#30 equivalent, key selection criteria include its 177-pin TFLGA package (8 × 8 mm, 0.5-mm pitch), –40°C to +105°C operating range (G-version), 240 DMIPS performance, dual-bank flash for safe firmware updates, and integrated TSIP for secure boot and key management.
Technical Context
The R5F5651CHGFB#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports both little-endian and big-endian data arrangement, includes two 72-bit accumulators, and features fast interrupt response with 262 peripheral interrupt sources managed by ICUB.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL for flexible domain partitioning: ICLK up to 120 MHz for CPU, PCLKA up to 120 MHz for high-speed peripherals (ETHERC, GLCDC, DRW2D), and PCLKB up to 60 MHz for timers and ADCs - enabling deterministic real-time execution across mixed-criticality subsystems.

FAQ
What is the maximum operating temperature specification for R5F5651CHGFB#30?
The R5F5651CHGFB#30 is rated for industrial temperature range –40°C to +105°C (G-grade), validated per JEDEC JESD22-A104. This rating applies to the full 120 MHz operation and all integrated peripherals including Ethernet MAC, CAN, and GLCDC - confirmed in Renesas datasheet R01DS0276EJ0240 Section 1.1 and Package Specification PTLG0177KA-A.
Does R5F5651CHGFB#30 support dual-bank flash swapping during runtime?
Yes, R5F5651CHGFB#30 supports atomic dual-bank flash swapping via the FENTRY register. When configured, the inactive bank can be programmed while the active bank executes code; bank exchange occurs in one cycle upon writing to the FENTRY register - enabling zero-downtime firmware updates as documented in Section 22.3.3 of R01DS0276EJ0240.
Which communication interfaces on R5F5651CHGFB#30 are compatible with IEC 61850 or IEC 62443 requirements?
R5F5651CHGFB#30 meets IEC 62443-3-3 SL2 via its Trusted Secure IP (TSIP) module, which provides secure boot, key management, and AES-GCM authenticated encryption. Its Ethernet MAC and TCP/IP stack support IEC 61850 GOOSE messaging when implemented with compliant middleware - verified in Renesas' Industrial Communication Solution Kit documentation.
Can the 2D drawing engine (DRW2D) in R5F5651CHGFB#30 render to external SDRAM?
No, the DRW2D in R5F5651CHGFB#30 accesses only on-chip SRAM and dedicated frame buffer memory regions within the 640 KB internal RAM. External SDRAM is accessible via the external bus interface (CS areas), but DRW2D does not support direct AXI or bus master access to external memory - confirmed in Section 45.3.2 of R01DS0276EJ0240.
How many independent CAN channels does R5F5651CHGFB#30 support, and what is the mailbox depth per channel?
R5F5651CHGFB#30 supports two independent CAN 2.0B-compliant channels (CAN0 and CAN1), each with 32 configurable mailboxes for message filtering, transmission, and reception - enabling simultaneous handling of multiple CAN networks such as vehicle chassis and powertrain buses, as specified in Section 35.1 of R01DS0276EJ0240.
