FAQ

What is the maximum operating frequency of the Arm® Cortex®-R5F core in S6J336CHSBSV20000?

The Arm® Cortex®-R5F core operates at up to 132 MHz, verified under recommended conditions (VCC5 = 5.0 V ±0.5 V, TA = -40 °C to 105 °C). This frequency is sustained across the full automotive temperature range and supports real-time execution of cluster UI tasks, CAN FD message handling, and ADC sampling without throttling.

Does S6J336CHSBSV20000 support both 3.3 V and 5 V supply rails simultaneously?

Yes - the device supports dual-supply configurations: VCC5/VCC53 pins accept either 5.0 V ±0.5 V or 3.3 V ±0.3 V, while DVCC and AVCC5 are internally regulated. The LQFP/TEQFP-144 variant allows mixed-voltage system design, such as 5 V for analog peripherals and 3.3 V for digital I/O, without external level shifters.

How many CAN FD channels does S6J336CHSBSV20000 integrate, and what is their message buffer capacity?

S6J336CHSBSV20000 integrates four independent CAN FD controllers, each with 16 KB of dedicated ECC-protected RAM - equivalent to a 128-message buffer per channel. This enables concurrent handling of high-priority cluster messages (e.g., speed, RPM) and lower-priority diagnostics or OTA traffic without arbitration delay.

Is the Secure Hardware Extension (SHE) module field-programmable, and does it require external keys?

The SHE module contains immutable ROM-based cryptographic algorithms and a one-time-programmable (OTP) key storage region. Keys are written during manufacturing or secure provisioning; no external key storage is required. Firmware can invoke SHE via defined APB registers to perform AES-128 encryption, SHA-256 hashing, and secure boot signature verification in ≤100 µs per operation.
