FAQ
What is the maximum operating frequency of the R7FS5D57A2A01CLK#AC1?
The R7FS5D57A2A01CLK#AC1 operates at a maximum CPU frequency of 200 MHz using its integrated PLL. This frequency is sustained across the full industrial temperature range (−40°C to +105°C) when supplied with 3.3 V ±5%, and is verified under worst-case voltage and temperature conditions per Renesas' characterization data. The R7FS5D57A2A01CLK#AC1 maintains timing closure for all peripherals-including CAN FD at 5 Mbps and Ethernet at 100 Mbps-at this speed.
Does the R7FS5D57A2A01CLK#AC1 support secure boot with public-key verification?
Yes, the R7FS5D57A2A01CLK#AC1 implements hardware-enforced secure boot using ECDSA-P256 signature verification on SHA-256 hashes of firmware images. This process occurs in ROM before any user code executes, and keys are stored in one-time-programmable (OTP) memory. The R7FS5D57A2A01CLK#AC1 also supports hash-based firmware authentication during runtime updates via its flash swap mechanism.
What peripheral interfaces does the R7FS5D57A2A01CLK#AC1 include for industrial networking?
The R7FS5D57A2A01CLK#AC1 integrates dual CAN FD controllers compliant with ISO 11898-1:2015 (up to 5 Mbps), a 10/100 Ethernet MAC with RMII interface and IEEE 1588 timestamping, and full-speed USB 2.0 device/host/OTG. These interfaces enable simultaneous multi-protocol connectivity in industrial gateways - for example, CAN FD for fieldbus integration, Ethernet for backhaul, and USB for local diagnostics - all managed by a single R7FS5D57A2A01CLK#AC1 chip.
Is the R7FS5D57A2A01CLK#AC1 qualified for extended temperature operation?
Yes, the R7FS5D57A2A01CLK#AC1 is rated for operation from −40°C to +105°C and is qualified per AEC-Q100 Grade 2 for reliability in harsh environments. It meets industrial-grade thermal cycling, humidity, and vibration specifications, and its LQFP-144 package includes an exposed thermal pad for efficient heat dissipation in sealed enclosures. This qualification makes the R7FS5D57A2A01CLK#AC1 suitable for railway, energy, and factory automation applications where ambient temperatures exceed standard commercial limits.
How does the R7FS5D57A2A01CLK#AC1 handle firmware updates in the field?
The R7FS5D57A2A01CLK#AC1 supports robust over-the-air (OTA) updates using its dual-bank flash architecture. Firmware images are written to the inactive bank while the active bank continues execution; upon successful validation (including SHA-256 hash and ECDSA signature check), the R7FS5D57A2A01CLK#AC1 performs an atomic bank swap via dedicated system control register. This ensures zero-downtime updates with guaranteed rollback capability if the new image fails integrity checks.
