Renesas R7FA6M5AH2CBG#AC0

Overview

R7FA6M5AH2CBG from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 2 MB dual-bank code flash with background/swap operation, 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, SDHI, QSPI/OSPI, advanced analog (dual 12-bit ADC/DAC), and Secure Crypto Engine 9 with TrustZone for secure embedded applications including industrial gateways and connected HMI devices.

For engineers reviewing the R7FA6M5AH2CBG datasheet, R7FA6M5AH2CBG pinout, R7FA6M5AH2CBG application, or R7FA6M5AH2CBG equivalent, key selection considerations include its -40°C to +85°C temperature grade, 176-pin FBGA package (PLBG0176GF-A), dual CAN FD support, integrated Ethernet MAC with RMII interface, and hardware-accelerated cryptography (AES/RSA/ECC/SHA256) for secure boot and firmware updates.

Technical Context

The R7FA6M5AH2CBG implements Armv8-M architecture with security extensions, including separate Secure and Non-secure SysTick timers, dual MPU instances (8 regions each), and CoreSight ETM-M33 for trace. Its memory subsystem supports concurrent read-while-write in dual-bank flash and ECC-protected SRAM for functional safety compliance.

Connectivity is centered on deterministic real-time interfaces: two CAN FD controllers (16 TX/16 RX buffers per channel), Ethernet MAC with DMA coupling to EDMAC, USBHS/USBFS with internal transceivers and 10-pipe FIFO, and QSPI/OSPI for external XIP-capable memory. Security relies on SCE9 accelerators, tamper detection pins, and TrustZone-enforced peripheral attribution.

FAQ

What is the maximum operating frequency of the R7FA6M5AH2CBG?

The R7FA6M5AH2CBG features an Arm Cortex-M33 core with a maximum operating frequency of 200 MHz. This speed is achieved using the on-chip PLL driven by the main crystal oscillator (8–24 MHz) or high-speed on-chip oscillator (HOCO). The R7FA6M5AH2CBG maintains this frequency across its full -40°C to +85°C operating range with appropriate voltage (2.7–3.6 V) and thermal design.

Does the R7FA6M5AH2CBG support Ethernet connectivity?

Yes, the R7FA6M5AH2CBG integrates a fully compliant IEEE 802.3 Ethernet MAC controller (ETHERC) with RMII interface support and tightly coupled Ethernet DMA Controller (EDMAC). It requires an external PHY LSI but handles all MAC-layer functions, including checksum offload and descriptor-based packet buffering-enabling deterministic real-time Ethernet communication without CPU intervention.

What security features does the R7FA6M5AH2CBG include?

The R7FA6M5AH2CBG includes Secure Crypto Engine 9 (SCE9) with hardware acceleration for AES-128/256, RSA-2048/4096, ECC, and SHA224/256; Arm TrustZone for secure/non-secure memory and peripheral partitioning; tamper detection pins; and device lifecycle management. These features collectively support secure boot, encrypted firmware updates, and protection of cryptographic keys in non-volatile memory.

What package type and pin count does the R7FA6M5AH2CBG use?

The R7FA6M5AH2CBG uses a 176-pin Fine-Pitch Ball Grid Array (FBGA) package, designated PLBG0176GF-A, measuring 7 mm × 7 mm with 0.5 mm ball pitch. It provides 132 general-purpose I/O pins, 17 of which are 5-V tolerant, and supports N-ch open-drain outputs and internal pull-up resistors-optimized for high-density industrial PCB layouts.

How much SRAM and flash memory does the R7FA6M5AH2CBG have?

The R7FA6M5AH2CBG includes 512 KB of on-chip SRAM with configurable parity or ECC protection, and 2 MB of dual-bank code flash memory supporting background programming and SWAP operations. It also provides 8 KB of data flash memory rated for 100,000 program/erase cycles-enabling robust firmware update mechanisms and parameter storage in mission-critical applications.
