Infineon Technologies S6J336AHTBSE20000

Overview

S6J336AHTBSE20000 from Infineon Technologies (formerly Cypress) is an automotive-grade 32-bit Arm® Cortex®-R5F microcontroller designed for instrument cluster metering systems. It delivers up to 132 MHz CPU operation, supports CAN FD and Secure Hardware Extension (SHE), integrates 2,112 KB TC-Flash and 128 KB TC-RAM, and operates across -40 °C to 105 °C for AEC-Q100 qualified applications including speedometer, tachometer, fuel gauge, and temperature display.

For engineers reviewing the S6J336AHTBSE20000 datasheet, S6J336AHTBSE20000 pinout, S6J336AHTBSE20000 application, or S6J336AHTBSE20000 equivalent, key selection criteria include ASIL-B compliance per ISO 26262, dual-voltage support (3.3 V/5 V), TEQFP-144 packaging, integrated LCD controller with 4 COM × 32 SEG, and hardware 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 real-time control and peripheral subsystems. Its Arm Cortex-R5F core includes tightly coupled instruction and data caches (16 KB each), FPU, PPU, and low-latency interrupt handling optimized for deterministic response in automotive cluster displays.

The peripheral set is partitioned into system, application, sound, external interface, and safety domains: CAN FD (4 channels, 128-message buffer/ch), multi-function serial interfaces (12 MFS + 10 I²C), 12-bit ADC (40 channels), stepper motor controller (6 gauges), and sound subsystem (PCM-PWM, I²S, mixer, waveform generator) - all synchronized via shared HPM/LLPM buses and PLL/SSCG clock generation.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the Arm Cortex-R5F core in S6J336AHTBSE20000?

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 and supports deterministic real-time execution required for ASIL-B cluster applications.

Does S6J336AHTBSE20000 support both 3.3 V and 5 V I/O operation simultaneously?

Yes - the device supports dual-voltage operation: VCC5/VCC53_1 accepts either 3.3 V ± 0.3 V or 5.0 V ± 0.5 V, and I/O ports can be configured per group for 3.3 V or 5 V logic levels. AVCC5 must match the selected VCC5 voltage to ensure ADC accuracy and analog peripheral stability.

How many CAN FD channels does S6J336AHTBSE20000 integrate, and what is their memory allocation?

S6J336AHTBSE20000 integrates four independent CAN FD controllers. Each channel has dedicated 16 KB of RAM with ECC protection, equivalent to a 128-message buffer capacity per channel - enabling high-throughput, fault-tolerant communication with minimal CPU intervention.

Is the LCD controller capable of driving both segmented and dot-matrix displays?

The integrated LCD controller supports only 4 COM × 32 SEG segmented LCDs, with dedicated COM/SEG output pins and programmable bias generation. It does not support dot-matrix or TFT displays; those require external graphics controllers or companion SoCs such as TRAVEO™ T2G series devices.
