Product details
Overview
R7FA8T1AFECBD#BC0 from Renesas is a high-performance 32-bit Arm® Cortex®-M85 microcontroller operating at up to 480 MHz, featuring 1 MB code flash, 12 KB data flash, and 1 MB SRAM with ECC/parity support. It integrates dual CAN FD, Ethernet MAC, USB 2.0 Full-Speed, SDHI × 2, I3C, and advanced analog peripherals (ADC12 × 2, DAC12 × 2, ACMPHS × 2), targeting industrial motor control and secure connected gateway applications.
For engineers reviewing the R7FA8T1AFECBD#BC0 datasheet, R7FA8T1AFECBD#BC0 pinout, R7FA8T1AFECBD#BC0 application, or R7FA8T1AFECBD#BC0 equivalent, key selection considerations include its 224-pin FBGA package, -40°C to +125°C junction temperature rating, TrustZone-enabled security architecture with RSIP-E51A, and dual-bank flash support for robust firmware updates in safety-critical systems.
Technical Context
The R7FA8T1AFECBD#BC0 implements Armv8.1-M architecture with Helium™ M-profile Vector Extension (MVE) for efficient signal processing, coupled with dual-core timer subsystems including GPT32 × 8 and AGT × 2 for precise motor phase control and low-power event timing. Its memory system separates secure/non-secure regions via TrustZone, with SRAM0 using ECC and SRAM1 using parity-enabling ASIL-B–capable functional safety designs.
Connectivity is hardware-accelerated: ETHERC/EDMAC enables zero-CPU packet handling; CANFD channels support ISO 11898-1 frames with 4 TX/16 RX buffers per channel; and USBFS operates as host or device with internal transceiver and 10-pipe buffer architecture. The RSIP-E51A crypto engine provides AES/RSA/ECC acceleration alongside SPA/DPA-resistant 128-bit HUK and true random number generation.

FAQ
What is the maximum operating frequency of the R7FA8T1AFECBD#BC0?
The R7FA8T1AFECBD#BC0 operates at a maximum frequency of 480 MHz using its Arm Cortex-M85 core. This speed is achieved with PLL1/PLL2 clock synthesis from internal oscillators (HOCO/MOCO) or external crystals (8–48 MHz). The core maintains full performance across its −40°C to +125°C operating junction temperature range, with dynamic voltage/frequency scaling supported via the power management unit.
Does the R7FA8T1AFECBD#BC0 support secure boot and cryptographic acceleration?
Yes, the R7FA8T1AFECBD#BC0 integrates Renesas Secure IP (RSIP-E51A) with AES/RSA/ECC/HASH acceleration and 128-bit hardware unique key (HUK) storage. Combined with Arm TrustZone®, it enables secure boot from immutable ROM (FSBL), authenticated firmware loading, and side-channel attack resistance (SPA/DPA). These features are fully operational in the R7FA8T1AFECBD#BC0's 224-pin FBGA package without external components.
What package type and pin count does the R7FA8T1AFECBD#BC0 use?
The R7FA8T1AFECBD#BC0 uses a 224-pin Fine-Pitch Ball Grid Array (FBGA) package, designated PLBG0224GD-A, with 13 mm × 13 mm body size and 0.8 mm ball pitch. It provides 174 GPIOs and supports industrial-grade thermal dissipation. This package matches the footprint of the higher-flash R7FA8T1AHECBD#BC0, enabling drop-in capacity upgrades where board space is constrained.
Which communication interfaces are integrated into the R7FA8T1AFECBD#BC0?
The R7FA8T1AFECBD#BC0 integrates CAN FD × 2, Ethernet MAC/EDMAC, USB 2.0 Full-Speed (host/device), SDHI × 2, I3C × 1, SCI × 6, SPI × 2, and I2C × 2. All interfaces operate concurrently with DMA/ELC offloading, and Ethernet and CAN FD are independently clocked and buffered to prevent bandwidth contention. No external PHY or transceiver is required for USB or CAN FD operation.
How does the R7FA8T1AFECBD#BC0 handle memory protection and reliability?
The R7FA8T1AFECBD#BC0 implements dual MPU instances (MPU_S/MPU_NS) with 8 regions each, TrustZone-based memory partitioning, and hardware ECC on SRAM0 plus parity on SRAM1. Code flash supports background erase/program and SWAP operations, while data flash guarantees 100,000 program/erase cycles. These features collectively meet IEC 61508 SIL2 and ISO 26262 ASIL-B requirements for functional safety without external error-correction circuitry.
