Infineon Technologies S6J336AHEBSE20000

Overview

S6J336AHEBSE20000 from Infineon Technologies (formerly Cypress) is an automotive-grade 32-bit Arm® Cortex®-R5F microcontroller designed for instrument cluster control, supporting speedometer, tachometer, fuel gauge, and temperature display functions. It integrates CAN FD (4 channels), Secure Hardware Extension (SHE), ASIL-B compliance per ISO 26262, 2,112 KB TC-Flash, and operates from -40 °C to 105 °C.

For engineers reviewing the S6J336AHEBSE20000 datasheet, S6J336AHEBSE20000 pinout, S6J336AHEBSE20000 application, or S6J336AHEBSE20000 equivalent, key selection criteria include CAN FD channel count, SHE security module support, dual-voltage operation (3.3 V/5 V), TC-RAM size (128 KB), and TEQFP-144 package compatibility with AEC-Q100 qualification.

Technical Context

This MCU implements a lockstep-capable Arm Cortex-R5F core running at up to 132 MHz with integrated L1 instruction and data caches (16 KB each), memory protection unit (MPU), and timer protection unit (TPU) for functional safety. It features three independent power domains (PD1/PD2/PD4) and supports partial wake-up via 8-channel free-run timers and 48-channel 12-bit ADC.

The peripheral set includes four CAN FD controllers with 16 KB ECC-protected RAM per channel (128-message buffer equivalent), dual I2S interfaces (one output-only), segment LCD controller (4 COM × 32 SEG), and multi-function serial interface (12 channels supporting UART, CSIO, LIN, I2C). Clocking uses PLL0 + SSCG0 with clock supervisor and low-voltage detection on both external supply and internal LDO outputs.

FAQ

What is the maximum operating frequency of the Arm Cortex-R5F core in S6J336AHEBSE20000?

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 supported by the on-chip PLL0 and SSCG0 clock generators, with timing closure confirmed per AC characteristics in Section 7.4 of the datasheet (Rev. *L).

Does S6J336AHEBSE20000 support CAN FD with simultaneous transmission and reception on all four channels?

Yes - all four CAN FD channels operate independently with full-duplex capability. Each channel has dedicated 16 KB ECC-protected RAM (equivalent to ~128-message buffers), enabling concurrent transmit/receive operations without CPU arbitration or shared resource contention.

How is the Secure Hardware Extension (SHE) configured in this part number?

S6J336AHEBSE20000 has MK_CEER fixed to Enable (per ordering code 'E' in position 10), meaning the SHE module is permanently activated at power-on. The SHE_MID is 0x000F_0300, and cryptographic operations (AES-128, SHA-256) are accessible via dedicated registers without software initialization overhead.

What LCD panel configurations are supported by the integrated segment driver?

The integrated LCD controller supports exactly 4 COM × 32 SEG passive-matrix panels with programmable bias, frame frequency, and contrast. It does not support dot-matrix TFT or active-matrix OLED; external drivers are required for those technologies. SEG/COM pins are mapped to dedicated GPIO groups in TEQFP-144 package (pins 1–32 and 113–116).
