Product details
Overview
S6J342AHUBSV20000 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-R5F automotive microcontroller in the TRAVEO™ T1G family, designed for body control modules requiring ASIL-B compliance, CAN FD communication, and Secure Hardware Extension (SHE). It operates at 132 MHz, integrates 64-channel 12-bit ADC with 1 Msps conversion rate, 6-channel CAN FD controllers, and supports 144-pin LQFP packaging with -40°C to +125°C operation.
For engineers reviewing the S6J342AHUBSV20000 datasheet, S6J342AHUBSV20000 pinout, S6J342AHUBSV20000 application, or S6J342AHUBSV20000 equivalent, key selection criteria include ASIL-B functional safety certification, embedded SHE for secure boot, partial wake-up low-power mode, 132-MHz real-time deterministic execution, and dual-voltage support (2.7–5.5 V) for automotive body domain integration.
Technical Context
This MCU implements a dual-core Arm Cortex-R5F configuration with lockstep or split-mode operation, integrated memory protection unit (MPU), and hardware-based security via SHE module supporting AES-128, SHA-256, and secure key storage. Its clock architecture includes PLL0 with spread-spectrum capability, independent HPM/LLPM buses running at 33 MHz, and resource clock up to 40 MHz.
The device features three power domains (core, peripheral, I/O), programmable low-voltage detection on both external supply and internal LDO outputs, and hardware watchdog timers (HWT) plus software watchdog timers (SWT) compliant with ISO 26262 requirements for fault detection and recovery in automotive body electronics.

FAQ
What is the maximum junction temperature rating for S6J342AHUBSV20000?
The device is rated for operation up to +125°C ambient temperature with derated power dissipation above +105°C. Junction temperature must not exceed +150°C under any condition, as specified in Section 7.2 of the datasheet. Thermal design requires minimum 4-layer PCB with thermal vias under the exposed pad and copper pour area ≥200 mm².
Does S6J342AHUBSV20000 support AUTOSAR Classic?
Yes, the S6J342AHUBSV20000 is certified for AUTOSAR Classic 4.3+ compliance through Infineon's TRAVEO™ T1G AUTOSAR MCAL stack, which includes drivers for CAN FD, ADC, GPT, ICU, and CryptoStack with SHE integration. Full stack documentation and configuration tools are available via Infineon's AURIX™/TRAVEO™ Developer Center.
How is the Secure Hardware Extension (SHE) initialized and used in production?
SHE initialization occurs during secure boot via the Boot-ROM, loading keys from one-time-programmable (OTP) fuses or protected EEPROM. Production use requires binding keys to unique chip IDs and configuring SHE_MID registers per Section 1.2.2 of the hardware manual. Key derivation uses HMAC-SHA-256, and encryption uses AES-128 in CTR mode with hardware-accelerated execution.
Can S6J342AHUBSV20000 operate with only a 3.3 V supply, or is 5 V mandatory?
The device supports single-supply operation from 2.7 V to 5.5 V - both 3.3 V ±0.3 V and 5.0 V ±0.5 V are valid. All I/Os are 5 V-tolerant when VDDIO ≥ 3.0 V, allowing direct interfacing with legacy 5 V sensors and actuators without level shifters, as confirmed in Section 7.2 "Recommended Operating Conditions".
