Infineon Technologies S6J325CKSPSE20000

Overview

S6J325CKSPSE20000 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-R5F microcontroller in the TRAVEO™ T1G family, operating up to 240 MHz with integrated 2D/3D graphics engines, Ethernet AVB MAC, four CAN-FD channels, and Secure Hardware Extension (SHE). It supports HyperBus™ memory interface, 120 GPIOs, and 50-channel 12-bit ADC-designed for automotive instrument clusters requiring real-time graphics rendering, safety-critical communication, and secure boot.

For engineers reviewing the S6J325CKSPSE20000 datasheet, S6J325CKSPSE20000 pinout, S6J325CKSPSE20000 application, or S6J325CKSPSE20000 equivalent, key selection criteria include Cortex-R5F real-time determinism, dual-display timing generator (TCON) support, ECC-protected RAM, CAN-FD message buffer allocation (128 per channel), and SHE-compliant cryptographic acceleration for AUTOSAR 4.0.3 compliance.

Technical Context

This MCU implements a dual-core lockstep-capable Cortex-R5F CPU with FPU, MPU, TPU, and ECC across all on-chip SRAM (TC-RAM, System-RAM, Backup-RAM). Its safety architecture includes clock supervisors for all source clocks, windowed watchdog timers, low-voltage detectors for both external supply and internal LDO outputs, and programmable CRC generators.

The graphics subsystem integrates a dedicated 2D engine with vector drawing, warping, scaling, rotation, and blending-paired with optional 3D engine and configurable display outputs (TTL/RSDS/LVDS up to 350 Mbps). Memory subsystem features HyperBus™ interface (up to 333 MB/s read), dual quad-SPI Flash, and DDR HSSPI for high-bandwidth external storage.

FAQ

What is the maximum operating frequency of the Cortex-R5F core in S6J325CKSPSE20000?

The Arm Cortex-R5F core operates at up to 240 MHz under specified voltage and temperature conditions (VDD = 1.2 V ±0.1 V, TA = –40°C to +105°C), with PLL0 providing the core clock. This frequency is validated across all speed grades in the S6J3200 series and confirmed in AC characteristics section (Table 8.4) of datasheet 002-05682 Rev. *R.

Does S6J325CKSPSE20000 support AUTOSAR 4.0.3 out of the box?

Yes-S6J325CKSPSE20000 includes hardware features required by AUTOSAR 4.0.3, including Memory Protection Unit (MPU), Trusted Platform Unit (TPU), ECC on all SRAM blocks, and Secure Hardware Extension (SHE) for cryptographic services. Infineon provides AUTOSAR-compliant MCAL drivers and configuration tools, but full stack integration requires customer-specific adaptation per project requirements.

How many display outputs does the TCON support simultaneously?

The integrated Timing Controller (TCON) supports up to two independent display outputs concurrently-one via TTL/RSDS and one via optional FPD-Link (LVDS) at up to 350 Mbps. Each output has dedicated pixel clock (TCON_CLK) and synchronization signals (HSYNC/VSNC), enabling dual-panel instrument clusters without external timing ICs or multiplexing logic.

Is HyperBus™ interface compatible with standard Octal SPI flash devices?

No-HyperBus™ is a proprietary Infineon/Cypress interface using an 8-bit DDR data bus and separate command/address lanes; it is not electrically or protocol-compatible with standard Octal SPI or Quad SPI flash. Only HyperBus™-compliant memories (e.g., Cypress Semper HyperFlash™) are supported, with timing defined in Section 8.4 of the datasheet.
