Infineon Technologies S6J336CHTBSC20000

Overview

S6J336CHTBSC20000 from Infineon Technologies (formerly Cypress) is an automotive-grade 32-bit Arm® Cortex®-R5F microcontroller designed for instrument cluster control, supporting CAN FD communication, Secure Hardware Extension (SHE), and ASIL-B compliance. It operates from -40 °C to 105 °C, integrates 2,112 KB TC-Flash and 128 KB TC-RAM, and delivers real-time motor control, LCD driving, and audio waveform generation in digital dashboards.

For engineers reviewing the S6J336CHTBSC20000 datasheet, S6J336CHTBSC20000 pinout, S6J336CHTBSC20000 application, or S6J336CHTBSC20000 equivalent, key selection criteria include its 132 MHz R5F core, dual-voltage operation (3.3 V/5 V), TEQFP-144 package, AEC-Q100 qualification, and integrated safety features including MPU, TPU, ECC, and watchdog timers.

Technical Context

This MCU implements a dual-domain power architecture (PD1/PD2/PD4) with dedicated clock domains for performance, low-power, and safety-critical peripherals. Its HPM bus runs at up to 132 MHz while LLPM and resource clocks support independent peripheral timing - enabling concurrent LCD refresh, stepper motor control, and CAN FD message handling without contention.

The device integrates hardware-accelerated security via SHE with fixed-function cryptographic engines (AES-128, SHA-256, HMAC), paired with memory protection units (MPU), timer protection units (TPU), and ECC on Flash/RAM - fulfilling ISO 26262 ASIL-B requirements for functional safety in automotive clusters.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-R5F core in S6J336CHTBSC20000?

The Arm® Cortex®-R5F 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 circuitry providing jitter-controlled clock synthesis.

Does S6J336CHTBSC20000 support CAN FD with ISO 11898-1:2015 physical layer compliance?

Yes - it integrates four fully compliant CAN FD controllers supporting data rates up to 5 Mbps, bit-rate switching, and ISO 11898-1:2015 frame formatting. Each channel includes 16 KB ECC-protected RAM for message buffering, eliminating need for external CAN transceivers with integrated buffers.

How is the Secure Hardware Extension (SHE) implemented, and what cryptographic functions does it support?

SHE is implemented as a dedicated hardware module with AES-128 encryption/decryption, SHA-256 hashing, and HMAC-SHA-256 authentication. It uses immutable keys stored in fuse-based registers and supports secure boot, firmware signature verification, and key derivation - all without CPU intervention or software exposure of secrets.

What are the supported package variants and thermal characteristics of the TEQFP-144 footprint?

S6J336CHTBSC20000 uses TEQFP-144 with 0.4 mm pitch and exposed thermal pad. Its θJA is 32 °C/W (JEDEC JESD51-2 standard, 4-layer board), and maximum junction temperature is 125 °C. The package meets AEC-Q200 stress test requirements for vibration, thermal cycling, and humidity resistance.
