FAQ
What is the maximum operating frequency of the R7FA8M1AHECFB#AA0?
The R7FA8M1AHECFB#AA0 operates at a maximum frequency of 480 MHz using its Arm Cortex-M85 core with Helium technology. This speed is achieved via PLL1 clock synthesis from the main oscillator (MOSC) or high-speed on-chip oscillator (HOCO). The device maintains this frequency across its full operating temperature range of −40°C to +125°C, with voltage supply requirements of 1.68–3.6 V on VCC and VCC2. All timing-critical peripherals-including GPT32 timers, USBHS, and Ethernet MAC-are fully functional at this rate.
Does the R7FA8M1AHECFB#AA0 support secure boot and cryptographic acceleration?
Yes, the R7FA8M1AHECFB#AA0 supports hardware-enforced secure boot through Arm TrustZone and Renesas Secure IP (RSIP-E51A). RSIP-E51A provides dedicated acceleration for AES (128/256-bit), RSA (2048/3072/4096-bit), ECC (secp256r1/secp384r1), and HASH (SHA-256/SHA-384) operations. It also includes a 128-bit unique ID, true random number generation, and tamper-resistant pins. Secure boot verifies signed firmware images before execution, and TrustZone enforces strict isolation between secure and non-secure worlds during runtime.
What package type and pin count does the R7FA8M1AHECFB#AA0 use?
The R7FA8M1AHECFB#AA0 uses a 144-pin LQFP package (PLQP0144KA-B), measuring 20 mm × 20 mm with 0.5 mm pitch. It provides 106 general-purpose I/O pins, supporting 5-V tolerant inputs, open-drain outputs, and programmable drive strength. This package variant is optimized for space-constrained industrial and automotive applications where full 176-pin functionality (e.g., SDRAM interface) is unnecessary. Pin compatibility is confirmed only within the RA8M1 FB suffix family.
Can the R7FA8M1AHECFB#AA0 interface with external Octal SPI flash memory?
Yes, the R7FA8M1AHECFB#AA0 includes a dedicated Octal Serial Peripheral Interface (OSPI) module compliant with JEDEC JESD251 Profile 1.0 (Octal SPI) and JESD252 (QSPI). It supports 1-/2-/4-/8-bit protocols, up to 200+ MHz operation, and on-the-fly decryption (DOTF) of encrypted content stored in external flash. The OSPI interface uses dedicated pins (OSPI_IO0–IO7, OSPI_CLK, OSPI_CS) and supports memory-mapped execution, enabling direct XIP from external flash without loading code into internal RAM.
What are the key differences between the R7FA8M1AHECFB#AA0 and R7FA8M1AHECFC#AA0?
The R7FA8M1AHECFB#AA0 (144-pin LQFP) and R7FA8M1AHECFC#AA0 (176-pin LQFP) share identical core architecture, memory sizes (2 MB flash, 1 MB SRAM), and peripheral sets-including Ethernet, USBHS, dual CAN FD, and OSPI. Key differences are package size (144 vs 176 pins), I/O count (106 vs 128), and omission of SDRAM interface and 32-bit external bus in the FB variant. They are not pin-compatible; migration requires PCB redesign. Both operate from −40°C to +125°C and support identical security features.
