Overview

S6J336CJTBSE20000 from Infineon Technologies (formerly Cypress) is an automotive-grade 32-bit Arm® Cortex®-R5F microcontroller designed for instrument cluster control, featuring CAN FD interface, Secure Hardware Extension (SHE), ASIL-B compliance, and operation from –40 °C to 105 °C. It integrates 2,112 KB TC-Flash, 128 KB TC-RAM, and supports 132 MHz core clock for real-time metering of speed, tachometer, fuel, and temperature.

For engineers reviewing the S6J336CJTBSE20000 datasheet, S6J336CJTBSE20000 pinout, S6J336CJTBSE20000 application, or S6J336CJTBSE20000 equivalent, key selection criteria include AEC-Q100 qualification, dual-voltage support (3.3 V/5 V), TEQFP-176 package with 126 GPIOs, integrated LCD controller, and hardware security for automotive firmware integrity.

Technical Context

This MCU implements a lockstep-capable Arm® Cortex®-R5F core with MPU, TPU, ECC-protected memory, and dual power domains (PD1/PD2/PD4) for functional safety partitioning. Its clock system includes PLL0/Expand PLL/SSCG0 and embedded oscillators (100 kHz slow clock, 4 MHz fast clock) enabling precise timing for real-time cluster display updates and CAN FD message scheduling.

The peripheral set targets driver-facing HMI: 48-channel 12-bit ADC for sensor input, 6-unit stepper motor controller for analog gauge actuation, segment LCD controller (4 COM × 32 SEG), and sound subsystem (PCM-PWM, I2S, waveform generator) for audible alerts - all operating under ISO 26262 ASIL-B requirements.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-R5F core in S6J336CJTBSE20000?

The 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 with on-chip PLL and SSCG providing jitter-controlled clock synthesis, enabling deterministic real-time response for cluster UI updates and CAN FD message handling.

Does S6J336CJTBSE20000 support both 3.3 V and 5 V power supplies simultaneously?

Yes - it supports dual-supply operation: VCC5 (5.0 V ±0.5 V) powers analog and I/O circuits, while VCC53_1/VCC53_2 (3.3 V ±0.3 V) supplies core logic and internal LDOs. The device includes dedicated power domain isolation (PD1/PD2/PD4) and voltage supervisors to ensure safe sequencing and fault detection during mixed-voltage operation.

How many CAN FD channels does S6J336CJTBSE20000 integrate, and what is their buffer capacity?

It integrates four independent CAN FD controllers, each with 16 KB of ECC-protected RAM - equivalent to a 128-message buffer per channel. Each channel supports bit rates up to 5 Mbps in data phase and includes hardware timestamping, loopback mode, and error counters compliant with ISO 11898-1:2015.

Is the Secure Hardware Extension (SHE) module enabled by default in S6J336CJTBSE20000?

Yes - the MK_CEER register is factory-configured to "Enable ON", activating SHE's AES-128 encryption, SHA-256 hashing, and secure key storage. The module is accessible only via privileged software and includes tamper-resistant memory protection, making it suitable for secure boot, firmware signing, and over-the-air update authentication per UNECE R155 requirements.
