FAQ

What is the maximum operating frequency and supported voltage range for S6J311AHAASE2000A?

The S6J311AHAASE2000A operates at a maximum CPU frequency of 96 MHz and requires a single 5 V supply with tolerance of ±5% to +10%. Internal voltage regulation generates 1.2 V for the core logic, while I/O circuits operate directly from the 5 V rail-eliminating need for external DC-DC converters in most automotive designs.

Does S6J311AHAASE2000A support CAN-FD and what are its timing capabilities?

Yes, it integrates one CAN-FD controller compliant with ISO 11898-1:2015 (V3.2.0), supporting bit rates up to 5 Mbps in FD mode and standard CAN up to 1 Mbps. It provides 192 dedicated receive and 32 transmit message buffers, with programmable acceptance filtering and hardware timestamping synchronized to the internal free-run timer.

How does the hardware security engine (SHE) function in this MCU?

The SHE implements FIPS PUB 197-compliant AES-128 encryption/decryption, SHA-256 hashing, and RSA signature verification acceleration. It supports secure boot via encrypted image decryption and authentication, key derivation using unique device ID, and protected storage of cryptographic keys-enabling compliance with UNECE WP.29 R155 cybersecurity management system requirements.

What packaging and thermal specifications apply to S6J311AHAASE2000A?

The device uses the LEU144 package: a 144-pin LQFP with 20 mm × 20 mm footprint and 0.5 mm lead pitch. It is rated for operation from -40°C to +125°C ambient temperature and qualified to AEC-Q100 Grade 2. Thermal resistance (θ_JA) is 32°C/W typical, requiring minimum 4-layer PCB with thermal vias under the exposed pad for sustained 96 MHz operation at maximum junction temperature.
