FAQ
What is the maximum operating frequency and supported voltage range?
The S6J312AHACSE2000A operates at up to 128 MHz with a single 5 V ±10% supply. Internal voltage regulation generates 1.2 V for the core, while I/O circuits run directly from 5 V - eliminating need for external level shifters in 5 V automotive systems. This configuration is validated across the full -40 °C to +105 °C ambient temperature range.
Does this MCU support ISO 26262 functional safety development?
Yes - the S6J312AHACSE2000A includes hardware features required for ASIL-B compliance: memory protection unit (MPU), SEC-DED ECC on TCM ports, clock supervisor with failover to CR oscillator, and hardware watchdog timer. Infineon provides certified safety documentation, FMEDA reports, and safety manuals aligned with ISO 26262-5 and -6.
How many CAN-FD channels does it support, and what are their buffer configurations?
It integrates three independent CAN-FD controllers, each supporting 5 Mbps data rate and 40 MHz CAN clock. Each channel provides 192 dedicated receive message buffers and 32 transmit message buffers - enabling concurrent handling of high-bandwidth diagnostic, control, and sensor data streams without host CPU intervention.
Is the SHE (Security Hardware Engine) enabled by default in this part number?
Yes - the "HAC" suffix in S6J312AHACSE2000A explicitly denotes SHE enabled (Table 1-2). The on-chip SHE v2.0 accelerator supports AES-128 encryption/decryption, SHA-256 hashing, and secure key generation/storage, and is accessible via dedicated registers without requiring external crypto co-processors.
