Renesas R7FA6M5BF2CBG#BC0

Overview

R7FA6M5BF2CBG from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 1 MB code flash, 8 KB data flash, and 512 KB SRAM with parity/ECC. It integrates Ethernet MAC, USB 2.0 High-Speed/Full-Speed, dual CAN FD, QSPI/OSPI, SDHI, and Secure Crypto Engine (AES/RSA/ECC/SHA256) with Arm TrustZone for industrial gateway and secure edge node applications.

For engineers reviewing the R7FA6M5BF2CBG datasheet, R7FA6M5BF2CBG pinout, R7FA6M5BF2CBG application, or R7FA6M5BF2CBG equivalent, key selection criteria include its -40°C to +85°C temperature grade, 176-pin FBGA package, dual CAN FD support, integrated Ethernet MAC with RMII, and hardware-accelerated cryptography for secure boot and firmware updates.

Technical Context

The R7FA6M5BF2CBG implements Armv8-M architecture with TrustZone security extension, supporting secure/non-secure execution environments via dual MPU instances (8 regions each) and configurable memory region attribution. Its system-level integration includes ETHERC/EDMAC for zero-CPU packet handling, DTC and 8-channel DMAC for autonomous data movement, and ELC for peripheral-to-peripheral event chaining without CPU intervention.

Security is enforced through SCE9 crypto accelerators (AES-128/256, RSA-2048/4096, ECC-256/384, SHA224/256), tamper detection on up to three dedicated pins, and lifecycle management for secure provisioning. Clocking combines MOSC/SOSC/HOCO/MOCO/LOCO sources with PLL/PLL2 and CAC for frequency accuracy validation.

FAQ

What is the maximum operating frequency of the R7FA6M5BF2CBG?

The R7FA6M5BF2CBG operates at a maximum frequency of 200 MHz using its Arm Cortex-M33 core. This speed is achievable with the on-chip PLL driven by the main crystal oscillator (8–24 MHz) or high-speed on-chip oscillator (HOCO). The device maintains full peripheral functionality-including Ethernet MAC, USB HS, and dual CAN FD-at this clock rate, as verified in Renesas' R01DS0366EJ0150 datasheet Section 1.4.

Does the R7FA6M5BF2CBG support Ethernet connectivity, and what interface is used?

Yes, the R7FA6M5BF2CBG integrates an IEEE 802.3-compliant Ethernet MAC controller (ETHERC) with RMII interface support. It does not include a PHY; external RMII PHY (e.g., LAN8720A) is required. The ETHERC connects directly to the Ethernet DMA Controller (EDMAC) for zero-CPU packet transfers, and pinout includes ETH_MDC, ETH_MDIO, ETH_TXD0/1, ETH_RXD0/1, ETH_TX_EN, and ETH_CRS_DV as defined in Table 1.15 of the R7FA6M5BF2CBG datasheet.

What security features are implemented in the R7FA6M5BF2CBG?

The R7FA6M5BF2CBG includes SCE9 hardware crypto acceleration (AES-128/256, RSA-2048/4096, ECC-256/384, SHA224/256), Arm TrustZone for secure/non-secure memory and peripheral partitioning, tamper detection on up to three dedicated pins, and secure key storage with lifecycle management. These features are documented in Sections 1.1 and 1.4 of the R01DS0366EJ0150 datasheet and enable secure boot, encrypted firmware updates, and TLS offload without software-only bottlenecks.

How much SRAM and flash memory does the R7FA6M5BF2CBG have?

The R7FA6M5BF2CBG contains 512 KB of on-chip SRAM with parity/ECC protection and 1 MB of code flash memory with dual-bank capability and background operation. It also includes 8 KB of data flash memory rated for 100,000 program/erase cycles. These values are explicitly listed in Table 1.13 (Product List) and Section 1.1 (Function Outline) of the R01DS0366EJ0150 datasheet revision 1.50.

Which CAN protocol versions does the R7FA6M5BF2CBG support?

The R7FA6M5BF2CBG supports CAN with Flexible Data-rate (CAN FD) compliant with ISO 11898-1, including both classical CAN frames and CAN FD frames with payloads up to 64 bytes and bit rates up to 5 Mbps. This is confirmed by the "B" feature code in its part number (R7FA6M5B...) and detailed in Table 1.14 (Function Comparison) and Section 1.8 of the R01DS0366EJ0150 datasheet.
