FAQ
What is the maximum operating frequency of the Arm Cortex-R5F core in the S6J351CHSBSE20000?
The S6J351CHSBSE20000 features an Arm Cortex-R5F core rated for operation up to 132 MHz under recommended conditions (VDD = 3.3 V ± 0.3 V or 5.0 V ± 0.5 V, TA = -40 to 105 °C). This frequency is sustained via internal PLL with SSCG, and all peripherals-including CAN FD and ADC-are fully synchronized at this clock rate without throttling.
Does the S6J351CHSBSE20000 support secure boot using its built-in SHE module?
Yes. The S6J351CHSBSE20000 integrates a Secure Hardware Extension (SHE) module with fixed MK_CEER configuration, enabling authenticated secure boot via SHA-256 and AES-128 operations. The SHE_MID register value is 0x000F_0300, and it supports key injection, encrypted firmware decryption, and runtime integrity checks per ISO/SAE 21434 guidelines.
How many CAN FD channels does the S6J351CHSBSE20000 provide, and what is the message buffer capacity per channel?
The S6J351CHSBSE20000 integrates four independent CAN FD controllers, each with a dedicated 128-message buffer (equivalent to 16 KB RAM per channel). Each buffer supports hardware timestamping, flexible DLC handling, and automatic retransmission-enabling full utilization of 5 Mbps FD data phase without CPU intervention.
What package type and pin count does the S6J351CHSBSE20000 use, and is it automotive-qualified?
The S6J351CHSBSE20000 uses a TEQFP-144 package with 0.5 mm pitch and an exposed thermal pad. It is qualified per AEC-Q100 Grade 2 (-40 to 105 °C), with moisture sensitivity level (MSL) 3 and lead-free (Pb-free) finish compliant with JEDEC J-STD-020.
