Infineon Technologies S6J336AHSBSL20000

Overview

S6J336AHSBSL20000 from Infineon Technologies (formerly Cypress) is an automotive-grade 32-bit Arm® Cortex®-R5F microcontroller designed for digital instrument cluster applications. It delivers up to 132 MHz core performance, integrates 2,112 KB TC-Flash and 128 KB TC-RAM, supports CAN FD communication, and operates across -40 °C to 105 °C for AEC-Q100 qualified metering systems including speed, tachometer, fuel, and temperature displays.

For engineers reviewing the S6J336AHSBSL20000 datasheet, S6J336AHSBSL20000 pinout, S6J336AHSBSL20000 application, or S6J336AHSBSL20000 equivalent, key selection criteria include ASIL-B compliance per ISO 26262, dual-voltage operation (3.3 V/5 V), integrated SHE security module, and TEQFP-144 packaging with 94 general-purpose I/O ports.

Technical Context

This MCU implements a dual-domain power architecture (PD1/PD2/PD4) with dedicated clock domains for real-time control and display subsystems. It features three independent bus matrices (HPM, LLPM, Resource), hardware-based memory protection (MPU/TPU), ECC-protected RAM and Flash, and deterministic interrupt latency enabled by low-latency interrupt support and 256-vector NVIC.

The device integrates tightly coupled peripherals for automotive HMI: a 4 COM × 32 SEG segment LCD controller, 12-bit ADC with 40 channels and partial wake-up capability, six-channel stepper motor controller (SMC), and dual I2S interfaces - one output-only for audio feedback and one full-duplex for system sound processing.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-R5F core in S6J336AHSBSL20000?

The Arm® Cortex®-R5F core operates at up to 132 MHz 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 and verified per AEC-Q100 stress testing protocols, enabling deterministic real-time response for gauge rendering and CAN FD message handling.

Does S6J336AHSBSL20000 support both 3.3 V and 5 V I/O simultaneously?

Yes - the device supports dual-voltage operation with VCC5 = 5.0 V ± 0.5 V or 3.3 V ± 0.3 V, and internal LDOs generate regulated 1.2 V core and 3.3 V I/O rails. Selected I/O pins are 5 V-tolerant, allowing direct interfacing with legacy 5 V sensors while maintaining 3.3 V logic compatibility for modern peripherals.

How many CAN FD channels does S6J336AHSBSL20000 integrate, and what is their buffer capacity?

S6J336AHSBSL20000 integrates four independent CAN FD controllers, each with 16 KB of dedicated RAM supporting ECC. This equates to a configurable message buffer capacity of up to 128 messages per channel, enabling concurrent handling of high-bandwidth diagnostic, instrumentation, and ADAS data streams at bit rates up to 5 Mbps.

Is the Secure Hardware Extension (SHE) module field-programmable and compatible with UNECE R156 compliance?

Yes - the SHE module includes programmable AES-128, SHA-256, and HMAC engines with protected key storage, and supports secure boot, firmware authentication, and secure OTA updates. Its architecture aligns with UNECE R156 cybersecurity management system requirements, and Infineon provides certified security documentation and test reports for automotive certification audits.
