Infineon Technologies S6J331EJSESE20000

Overview

S6J331EJSESE20000 from Infineon Technologies (formerly Cypress) is a 32-bit automotive microcontroller in the TRAVEO™ T1G family, built around an Arm® Cortex®-R5F core operating at up to 240 MHz. It integrates 4,160 KB program Flash, 512 KB RAM, 12-bit ADC with 48 channels, 6 CAN-FD interfaces, and supports instrument cluster applications with TFT display control via RGB888 output and LCD controller (4 COM × 32 SEG). Designed for ASIL-B functional safety compliance, it includes SHE security, MPU, ECC, and watchdog timers.

For engineers reviewing the S6J331EJSESE20000 datasheet, S6J331EJSESE20000 pinout, S6J331EJSESE20000 application, or S6J331EJSESE20000 equivalent, key selection criteria include real-time deterministic performance (Cortex-R5F @ 240 MHz), integrated graphics engine clock (80 MHz), dual-domain power management (5V/3V/1.2V supplies), and automotive network support (CAN-FD, optional Ethernet AVB, MediaLB).

Technical Context

The S6J331EJSESE20000 implements a dual-bus architecture with HPM (200 MHz) and LLPM (240 MHz) domains, enabling concurrent high-speed peripheral access and real-time CPU execution. Its safety subsystem includes MPU for AHB/AXI, TPU for time-triggered execution, ECC on Flash and SRAM, and CRC generators supporting programmable polynomials.

Graphics capability is delivered through a dedicated 2D graphic engine clocked at 80 MHz, driving RGB888 TTL output at WQVGA (480×272) resolution and 60 fps. Display timing is configurable via internal or external clock sources, and the LCD controller supports multiplexed segment drive (4 COM × 32 SEG) for analog gauge interfaces.

FAQ

What is the maximum operating temperature range for S6J331EJSESE20000?

The S6J331EJSESE20000 is qualified for automotive Grade 2 operation, with a junction temperature range of −40 °C to +105 °C. This rating is validated per AEC-Q100 Rev-G stress test standards and applies across all supported voltage domains (VCC5, VCC3, VCC12) and clock frequencies up to 240 MHz.

Does S6J331EJSESE20000 support AUTOSAR 4.x natively?

Yes-the S6J331EJSESE20000 includes hardware features required by AUTOSAR 4.0.3, including memory protection unit (MPU), time protection unit (TPU), and deterministic interrupt latency (<10 µs). Infineon provides certified MCAL drivers and configuration tools compatible with Vector DaVinci and ETAS ISOLAR.

Can the integrated 2D graphics engine drive a 7-inch WVGA display?

No-the graphics engine targets WQVGA (480×272) at 60 fps with RGB888 output. Driving WVGA (800×480) would exceed its pixel clock limit (25 MHz) and frame buffer bandwidth. For larger displays, external display controllers or higher-tier TRAVEO™ T2G devices are recommended.

Is external Flash required for booting S6J331EJSESE20000?

No-booting is supported from internal 4,160 KB Program Flash or external HyperBus™ Flash. The device includes a 16 KB Boot-ROM with secure boot loader that validates signed firmware images before execution, enabling robust OTA update mechanisms without external memory dependency.
