FAQ

What is the maximum operating frequency and core architecture of the R7FA6M5BG3CFP#BA0?

The R7FA6M5BG3CFP#BA0 features an Arm Cortex-M33 core operating at a maximum frequency of 200 MHz. It implements the Armv8-M architecture with Security Extension (TrustZone), including separate Secure and Non-secure Memory Protection Units (MPU_S and MPU_NS), each with eight configurable regions. This architecture enables hardware-enforced isolation between trusted firmware and application code, critical for secure boot and cryptographic key management in the R7FA6M5BG3CFP#BA0.

Does the R7FA6M5BG3CFP#BA0 support Ethernet, and what interface does it use?

Yes, the R7FA6M5BG3CFP#BA0 integrates an IEEE 802.3-compliant Ethernet MAC controller (ETHERC) that supports RMII interface only-not MII or GMII. It requires an external PHY connected via RMII signals (ETH_TXD0/1, ETH_RXD0/1, ETH_TXEN, ETH_CRS_DV, ETH_REF_CLK). The ETHERC is tightly coupled with the Ethernet DMA Controller (EDMAC) to enable zero-copy packet transfers without CPU intervention, reducing latency and load in the R7FA6M5BG3CFP#BA0-based networking applications.

What cryptographic accelerators are included in the R7FA6M5BG3CFP#BA0's Secure Crypto Engine?

The R7FA6M5BG3CFP#BA0 integrates Secure Crypto Engine 9 (SCE9), which provides hardware acceleration for symmetric algorithms (AES-128/192/256), asymmetric algorithms (RSA-2048/3072/4096, ECC NIST P-256/P-384), and hash functions (SHA224, SHA256, GHASH). It also includes a 128-bit unique ID, tamper detection circuitry, and resistance to power analysis attacks. These capabilities are fully leveraged by the R7FA6M5BG3CFP#BA0's TrustZone environment to protect keys and perform secure boot verification.

How much SRAM and flash memory does the R7FA6M5BG3CFP#BA0 have, and what protection mechanisms apply?

The R7FA6M5BG3CFP#BA0 includes 512 KB of on-chip SRAM configured with 448 KB protected by parity and 64 KB protected by ECC, plus 1.5 MB of dual-bank code flash memory and 8 KB of data flash memory rated for 100,000 program/erase cycles. The dual-bank flash supports background programming and SWAP operations, allowing firmware updates without halting execution-a key reliability feature of the R7FA6M5BG3CFP#BA0 in mission-critical deployments.

What is the package type and operating temperature range for the R7FA6M5BG3CFP#BA0?

The R7FA6M5BG3CFP#BA0 is supplied in a 100-pin LQFP package (PLQP0100KB-B), measuring 14 mm × 14 mm with 0.5 mm pitch. It is rated for industrial operation from -40°C to +105°C ambient temperature, making it suitable for harsh environments such as factory automation, transportation systems, and outdoor edge infrastructure where thermal stability is essential for the R7FA6M5BG3CFP#BA0's long-term reliability.
