FAQ

What is the maximum operating frequency of the R7FS7G27G3A01CFC#BA0?

The R7FS7G27G3A01CFC#BA0 operates at a maximum CPU frequency of 240 MHz using its on-chip PLL with fractional divider. This frequency is sustained across the full −40°C to +105°C industrial temperature range when powered within the specified 2.7–3.6 V supply window. The R7FS7G27G3A01CFC#BA0 achieves this performance while maintaining tight timing margins for all peripherals, including USB and CAN FD interfaces.

Does the R7FS7G27G3A01CFC#BA0 support secure boot with cryptographic verification?

Yes, the R7FS7G27G3A01CFC#BA0 includes a ROM-based Secure Boot loader that validates digital signatures of firmware images using ECDSA-P256 before execution. It leverages on-chip hardware accelerators for SHA-256 and ECDSA, and stores root public keys in write-protected memory. This capability is integral to the R7FS7G27G3A01CFC#BA0 and does not require external components or software libraries.

What package type and pin count does the R7FS7G27G3A01CFC#BA0 use?

The R7FS7G27G3A01CFC#BA0 is supplied in a 176-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) with exposed thermal pad. This package is fully documented in the Synergy S7 Group User's Manual and matches the pin assignments for all S7G2-series MCUs in the same footprint. The R7FS7G27G3A01CFC#BA0 uses all 176 pins for I/O, power, clock, and debug functions - no NC pins are present in this variant.

Can the R7FS7G27G3A01CFC#BA0 execute firmware updates without interrupting real-time operation?

Yes, the R7FS7G27G3A01CFC#BA0 supports seamless firmware updates via its dual-bank Flash architecture. One bank runs active firmware while the other receives and validates new code; a controlled reset then switches execution to the updated bank. This mechanism is implemented in hardware and supported by the Synergy Software Package (SSP), enabling zero-downtime updates for the R7FS7G27G3A01CFC#BA0 in deployed systems.

Which communication interfaces with hardware acceleration are integrated into the R7FS7G27G3A01CFC#BA0?

The R7FS7G27G3A01CFC#BA0 integrates hardware-accelerated CAN FD (up to 5 Mbps), USB 2.0 Full-Speed (with integrated transceiver), and cryptographic engines for AES-128/256, SHA-256, and ECDSA-P256. These accelerators operate independently of the CPU, allowing concurrent protocol handling and encryption without degrading real-time task performance - a core capability of the R7FS7G27G3A01CFC#BA0.
