FAQ

What is the maximum operating frequency of the R7FS5D57C2A01CLK#AC0?

The R7FS5D57C2A01CLK#AC0 operates at a maximum CPU frequency of 200 MHz using its integrated PLL. This frequency is sustained across industrial temperature ranges (−40°C to +85°C) with appropriate voltage regulation and thermal design. The R7FS5D57C2A01CLK#AC0 achieves this speed while maintaining full peripheral functionality, including dual CAN FD and hardware crypto acceleration, without throttling.

Does the R7FS5D57C2A01CLK#AC0 support CAN FD, and how many instances are available?

Yes, the R7FS5D57C2A01CLK#AC0 integrates two independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports data rates up to 5 Mbps, flexible data-length up to 64 bytes, and seamless fallback to classical CAN. Both controllers feature dedicated message RAM, filtering, and bit-rate switching logic - enabling concurrent use in applications like automotive diagnostics and industrial network bridging.

What security features are implemented in hardware on the R7FS5D57C2A01CLK#AC0?

The R7FS5D57C2A01CLK#AC0 includes a dedicated security engine with hardware-accelerated AES-256 (ECB/CBC/CTR/GCM), SHA-256, and TRNG. It also supports secure boot with ECDSA-P256 signature verification, tamper detection, and debug lock via 128-bit ID code. These features are physically isolated from the main CPU domain and operate independently - ensuring cryptographic operations remain protected even if the application firmware is compromised.

What is the package type and pin count of the R7FS5D57C2A01CLK#AC0?

The R7FS5D57C2A01CLK#AC0 is housed in a 144-pin LQFP package measuring 20 mm × 20 mm with 0.5 mm pitch. It provides 112 general-purpose I/O pins, plus dedicated power, ground, clock, reset, and debug signals. The package is RoHS-compliant and rated MSL3, making it suitable for standard surface-mount assembly processes in industrial and automotive environments.

Is the R7FS5D57C2A01CLK#AC0 pin-compatible with other S5 Series microcontrollers?

The R7FS5D57C2A01CLK#AC0 shares the same 144-pin LQFP footprint and pin assignment with other S5D5 group members such as R7FS5D57C3A01CLK#AC0 and R7FS5D57C4A01CLK#AC0. Pin compatibility extends to power, clock, reset, debug, and all peripheral signal mappings - enabling drop-in replacement within the same flash/SRAM variant family without PCB redesign.
