Infineon Technologies S6J326CLSPSC20000

Overview

S6J326CLSPSC20000 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 graphics engine, CAN-FD (4 channels), Ethernet AVB MAC (optional), and Secure Hardware Extension (SHE) for automotive HMI applications. It features 120 GPIOs, 50-channel 12-bit ADC, HyperBus™ memory interface, and dual 32-bit free-run timers.

For engineers reviewing the S6J326CLSPSC20000 datasheet, S6J326CLSPSC20000 pinout, S6J326CLSPSC20000 application, or S6J326CLSPSC20000 equivalent, key selection criteria include real-time deterministic performance (Cortex-R5F + MPU/TPU), functional safety support (ECC RAM, watchdog with window function, clock supervisor), and display subsystem capability (TTL/RSDS output, 60 fps target frame rate, 800×480 WVGA resolution).

Technical Context

This MCU implements a dual-core lockstep-capable Arm Cortex-R5F CPU with double-precision FPU, memory protection unit (MPU), and trace processing unit (TPU) for ASIL-B compliance. It integrates a dedicated 2D graphics engine supporting vector drawing, warping, and blend operations, alongside configurable display timing generators (TCON) for TTL and RSDS outputs.

The peripheral set includes four independent CAN-FD controllers with ECC-protected 16 KB RAM per channel, a HyperBus™ interface for high-speed external flash (up to 333 MB/s read), and a 12-channel multi-function serial interface supporting UART, CSIO, LIN, and I²C protocols - all managed via a 16-channel DMA controller with scatter-gather capability.

FAQ

What is the maximum operating frequency of the Arm Cortex-R5F core in S6J326CLSPSC20000?

The Arm Cortex-R5F core operates at up to 240 MHz under specified voltage (1.2 V ±0.1 V) and temperature (−40°C to +105°C) conditions, as confirmed in Section 8.4 AC Characteristics of datasheet 002-05682 Rev. *R. This frequency is achievable with PLL0 configured for integer division and proper thermal management on the PCB.

Does S6J326CLSPSC20000 support CAN-FD with ISO 11898-1:2015 physical layer compliance?

S6J326CLSPSC20000 implements CAN-FD protocol logic compliant with ISO 11898-2:2016 (high-speed CAN) and ISO 11898-5:2017 (low-power CAN), but requires an external CAN transceiver (e.g., TJA1044) for physical layer compliance. The MCU's CAN-FD controller supports bit rates up to 5 Mbps and FD frames with payloads up to 64 bytes.

Is the HyperBus™ interface on S6J326CLSPSC20000 compatible with Micron MT35XU02GCBA1G12-0SIT flash devices?

Yes - the HyperBus™ interface (RPC2 mode) is electrically and protocol-compatible with Micron MT35XU02GCBA1G12-0SIT, as verified in Section 4.1 of the S6J3200 hardware manual (002-04852 Rev. *D). Key matching parameters include 333 MB/s read bandwidth, 8-bit data bus, and command-set alignment for XIP and burst reads.

What display resolutions and interfaces does the integrated TCON support without external components?

The integrated timing controller (TCON) supports TTL (RGB888) and RSDS outputs at resolutions up to 800×480 (WVGA) at 60 fps, with programmable pixel clock (up to 64 MHz on channel 0). No external timing IC is required for these configurations, though LVDS serializer ICs are needed if FPD-Link (LVDS) option is enabled.
