FAQ

What is the maximum operating frequency and core architecture of the R7FA8E2AFDCBD#UC0?

The R7FA8E2AFDCBD#UC0 features an Arm® Cortex®-M85 core with Helium™ technology, operating at a maximum frequency of 480 MHz. It implements the Armv8.1-M architecture profile with Armv8-M Security Extension, M-profile Vector Extension (MVE-F), and IEEE 754-compliant floating-point unit - enabling high-throughput signal processing and machine learning inference directly on the R7FA8E2AFDCBD#UC0 without external accelerators.

Does the R7FA8E2AFDCBD#UC0 support secure firmware updates and cryptographic operations?

Yes, the R7FA8E2AFDCBD#UC0 supports secure firmware updates via dual-bank flash with atomic SWAP operation, allowing background programming and glitch-resistant bank switching. Cryptographic operations are accelerated by the integrated Renesas Secure IP (RSIP-E51A), which provides hardware AES-128/256, SHA-256, ECDSA, true random number generation, and protected key storage - all used during verified boot and runtime TLS execution on the R7FA8E2AFDCBD#UC0.

What graphics capabilities does the R7FA8E2AFDCBD#UC0 provide for embedded displays?

The R7FA8E2AFDCBD#UC0 integrates a Graphics LCD Controller (GLCDC) supporting RGB888 output and WVGA resolution, plus a dedicated 2D Drawing Engine (DRW) that performs antialiased rasterization, texture mapping, alpha blending, and ARGB8888 framebuffer composition in hardware. These features eliminate the need for external GPUs and reduce CPU load - enabling responsive, visually rich UIs directly on the R7FA8E2AFDCBD#UC0 in resource-constrained embedded systems.

How many CAN FD interfaces does the R7FA8E2AFDCBD#UC0 include, and what standards do they comply with?

The R7FA8E2AFDCBD#UC0 includes two independent CAN FD modules, each supporting both classical CAN and CAN FD frames per ISO 11898-1. Each channel provides 4 transmit buffers and 16 receive buffers, with bit rates up to 5 Mbps in FD mode. This dual-CAN FD capability enables simultaneous communication with multiple vehicle domains - a key requirement for diagnostic gateways and advanced driver assistance systems built around the R7FA8E2AFDCBD#UC0.

What is the package type and thermal rating of the R7FA8E2AFDCBD#UC0?

The R7FA8E2AFDCBD#UC0 is housed in a 224-pin Fine-Pitch Ball Grid Array (FBGA) package measuring 13 mm × 13 mm with 0.8 mm pitch and Sn (tin-only) Pb-free terminations. It is rated for junction temperatures from −40°C to +105°C, making it suitable for industrial and automotive under-hood applications where sustained thermal performance and reliability are critical - confirmed by Renesas' characterization of the R7FA8E2AFDCBD#UC0 across this full range.
