FAQ

What is the maximum operating frequency of the R7FS5D57C3A01CFP#AA0?

The R7FS5D57C3A01CFP#AA0 operates at a maximum CPU frequency of 180 MHz using its integrated PLL with external crystal or internal FLL. This frequency is fully supported across the industrial temperature range (−40°C to +105°C) with appropriate voltage scaling (VCC = 3.3 V ±10%). The R7FS5D57C3A01CFP#AA0 maintains timing compliance under worst-case process/voltage/temperature corners per Renesas' published electrical characteristics.

Does the R7FS5D57C3A01CFP#AA0 support secure boot with hardware root-of-trust?

Yes, the R7FS5D57C3A01CFP#AA0 implements a hardware-enforced secure boot process that validates the digital signature of the primary bootloader using public-key cryptography before execution. This immutable root-of-trust is stored in one-time-programmable (OTP) memory and verified by on-chip ROM code - ensuring the R7FS5D57C3A01CFP#AA0 only executes authenticated firmware images.

How many CAN FD interfaces does the R7FS5D57C3A01CFP#AA0 integrate, and what are their data rates?

The R7FS5D57C3A01CFP#AA0 integrates two independent CAN FD controllers compliant with ISO 11898-1:2015. Each supports arbitration bit rates up to 1 Mbps and data bit rates up to 5 Mbps, with flexible data field lengths (up to 64 bytes) and CRC coverage. Both controllers operate concurrently without resource contention, enabling the R7FS5D57C3A01CFP#AA0 to serve as a dual-domain automotive or industrial network bridge.

What analog peripherals are included in the R7FS5D57C3A01CFP#AA0?

The R7FS5D57C3A01CFP#AA0 includes a 12-bit 1 Msps successive-approximation ADC with 24 input channels, two 12-bit voltage-output DACs, two rail-to-rail operational amplifiers, two comparators with selectable hysteresis, and a temperature sensor. These peripherals are synchronized via the event link controller (ELC), allowing precise timing coordination - essential for analog signal conditioning in motor control and sensor acquisition applications using the R7FS5D57C3A01CFP#AA0.

Is the R7FS5D57C3A01CFP#AA0 pin-compatible with other devices in the Synergy S5 Series?

No, the R7FS5D57C3A01CFP#AA0 is not pin-compatible with other S5 Series devices due to its unique 144-pin LQFP package and full peripheral set. While it shares the same underlying MCU architecture and register map with other S5D5 variants, pin assignments differ significantly across package options (e.g., 100-pin vs. 144-pin). Migration requires PCB redesign; however, firmware reuse is supported via Renesas' SSP and e2 studio toolchain for the R7FS5D57C3A01CFP#AA0.
