Overview

R7FA6M5BG3CFB#BA0 from Renesas is a high-performance 32-bit Arm Cortex-M33 microcontroller operating at up to 200 MHz, featuring 1.5 MB code flash, 8 KB data flash, and 512 KB SRAM with ECC/parity. It integrates dual CAN FD controllers, Ethernet MAC, USB 2.0 High-Speed/Full-Speed, QSPI/OSPI, SDHI, and Secure Crypto Engine (SCE9) with TrustZone for secure IoT edge nodes and industrial gateways.

For engineers reviewing the R7FA6M5BG3CFB#BA0 datasheet, R7FA6M5BG3CFB#BA0 pinout, R7FA6M5BG3CFB#BA0 application, or R7FA6M5BG3CFB#BA0 equivalent, key selection criteria include its -40°C to +105°C operation, 144-pin LQFP package, dual-bank flash for robust OTA updates, hardware-accelerated AES/RSA/ECC, and integrated CTSU for touch HMI in space-constrained industrial control panels.

Technical Context

The R7FA6M5BG3CFB#BA0 implements Armv8-M with TrustZone, enabling secure/non-secure world isolation across memory regions (flash/SRAM/data flash), peripherals, and MPU configurations. Its dual CAN FD channels support ISO 11898-1 frames with 16 transmit/receive buffers per channel, while the ETHERC/EDMAC pair enables zero-CPU packet handling via DMA.

Security is enforced through SCE9 - delivering AES-128/256, RSA-2048/4096, ECC-256/384, SHA-256, and tamper detection - tightly coupled with TrustZone's peripheral attribution and lifecycle management. Clocking includes PLL/PLL2, HOCO/MOCO/LOCO oscillators, and CAC for real-time frequency accuracy monitoring.

FAQ

What is the maximum operating frequency and core architecture of the R7FA6M5BG3CFB#BA0?

The R7FA6M5BG3CFB#BA0 features an Arm Cortex-M33 core operating at up to 200 MHz, implementing the Armv8-M architecture with Security Extension (TrustZone). It includes dual Memory Protection Units (MPUs) - one secure and one non-secure - each supporting eight memory regions, enabling robust software isolation for secure firmware execution and peripheral access control in the R7FA6M5BG3CFB#BA0.

Does the R7FA6M5BG3CFB#BA0 support CAN FD, and how many channels are available?

Yes, the R7FA6M5BG3CFB#BA0 supports CAN with Flexible Data-rate (CAN FD) with two independent channels compliant with ISO 11898-1. Each channel provides 16 dedicated transmit buffers and 16 receive buffers, enabling concurrent high-bandwidth communication with legacy CAN and CAN FD nodes - a key capability confirmed in the R7FA6M5BG3CFB#BA0 datasheet section 1.4 and Table 1.14.

What security features does the R7FA6M5BG3CFB#BA0 integrate beyond Arm TrustZone?

Beyond Arm TrustZone, the R7FA6M5BG3CFB#BA0 integrates the Secure Crypto Engine 9 (SCE9), which provides hardware-accelerated symmetric (AES-128/256), asymmetric (RSA-2048/4096, ECC-256/384), and hash (SHA-256) operations. It also includes tamper detection pins, power analysis resistance, a 128-bit unique ID, and device lifecycle management - all documented in the R7FA6M5BG3CFB#BA0 datasheet sections 1.1 and 1.4.

What is the package type and pin count of the R7FA6M5BG3CFB#BA0?

The R7FA6M5BG3CFB#BA0 uses a 144-pin LQFP package (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch. It provides 109 general-purpose I/O pins, 21 of which are 5-V tolerant, along with dedicated power, clock, reset, and peripheral interface pins - as specified in the R7FA6M5BG3CFB#BA0 part numbering scheme (Figure 1.2) and Table 1.13 of the datasheet.

Does the R7FA6M5BG3CFB#BA0 include integrated analog peripherals, and what are their specifications?

Yes, the R7FA6M5BG3CFB#BA0 integrates two 12-bit successive approximation ADC units (ADC12): Unit 0 supports up to 13 channels, Unit 1 supports up to 16 channels, with three shared analog input pins (AN000/AN100, etc.), enabling up to 26 total analog inputs. It also includes two 12-bit DACs (DAC12) and an on-die temperature sensor (TSN) - all confirmed in Table 1.9 and Figure 1.1 of the R7FA6M5BG3CFB#BA0 datasheet.
