Renesas R7FA6M5BF2CBG#AC0

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, 512 KB SRAM with parity/ECC, dual CAN FD controllers, Ethernet MAC, USB 2.0 HS/FS, QSPI/OSPI, and integrated Secure Crypto Engine (SCE9) with TrustZone for secure embedded applications in industrial gateways and connected edge devices.

For engineers reviewing the R7FA6M5BF2CBG datasheet, R7FA6M5BF2CBG pinout, R7FA6M5BF2CBG application, or R7FA6M5BF2CBG equivalent, key selection considerations include its -40°C to +85°C temperature grade, 176-pin FBGA package (PLBG0176GF-A), 1 MB flash capacity (vs. 2 MB in AH/H variants), CAN FD support (B-series), and full peripheral integration including SDHI, SSIE, CEC, and CTSU.

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 hardware-isolated memory regions for flash, SRAM, and peripherals. Its SCE9 accelerator offloads AES, RSA, ECC, SHA256, and GHASH operations while enabling tamper detection and power analysis resistance.

It integrates dual-bank flash with background operation and SWAP capability for robust firmware updates, alongside advanced timing resources: two 12-bit ADCs (5 Msps interleaved), two 12-bit DACs, six AGT timers, four GPT32 channels, and RTC with calendar mode and VBATT backup - all coordinated via Event Link Controller (ELC) for CPU-free peripheral chaining.

FAQ

What is the maximum operating frequency of the R7FA6M5BF2CBG?

The R7FA6M5BF2CBG features an Arm Cortex-M33 core with a maximum operating frequency of 200 MHz. This clock speed is achieved using the on-chip PLL driven by the main clock oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The R7FA6M5BF2CBG maintains this performance across its full -40°C to +85°C operating temperature range with appropriate voltage regulation (VCC = 2.7–3.6 V).

Does the R7FA6M5BF2CBG support CAN FD, and how many channels are available?

Yes, the R7FA6M5BF2CBG supports CAN with Flexible Data-rate (CAN FD) as indicated by the "B" in its part number suffix. It integrates two independent CAN FD controllers compliant with ISO 11898-1, each supporting classical CAN and CAN FD frames up to 5 Mbps. Each channel provides 16 transmit and 16 receive buffers, enabling robust multi-node communication in automotive and industrial networks.

What type of package does the R7FA6M5BF2CBG use, and what are its key mechanical dimensions?

The R7FA6M5BF2CBG uses a 176-pin Fine-Pitch Ball Grid Array (FBGA) package with designation PLBG0176GF-A. Its mechanical dimensions are 7 mm × 7 mm with a 0.5 mm ball pitch. The package is RoHS-compliant with Sn-only (tin) terminal finish and supports automated surface-mount assembly with standard reflow profiles for lead-free processes.

How much on-chip memory does the R7FA6M5BF2CBG include, and what types are available?

The R7FA6M5BF2CBG includes 1 MB of code flash memory (dual-bank with background operation and SWAP capability), 8 KB of data flash memory rated for 100,000 program/erase cycles, and 512 KB of on-chip SRAM with configurable parity or ECC protection. Additionally, it provides 1 KB of standby SRAM powered by VBATT for RTC and critical state retention during power loss.

What security features are integrated into the R7FA6M5BF2CBG?

The R7FA6M5BF2CBG integrates Renesas' Secure Crypto Engine 9 (SCE9) with hardware acceleration for AES, RSA, ECC, DSA, SHA224, SHA256, and GHASH. It also includes Arm TrustZone for hardware-enforced secure/non-secure world separation, tamper detection circuitry, dedicated tamper pins, secure key management, and device lifecycle management - all coordinated to deliver secure element-level functionality without external components.
