Product details
Overview
S6J342AJTBSE20000 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-R5F automotive microcontroller in the TRAVEO™ T1G series, designed for body control modules with CAN FD and Secure Hardware Extension (SHE). It operates at 132 MHz, supports 2.7–5.5 V supply, integrates 64-channel 12-bit ADC (1 Msps), six CAN FD controllers, and meets ASIL-B per ISO 26262 for HVAC and gateway applications.
For engineers reviewing the S6J342AJTBSE20000 datasheet, S6J342AJTBSE20000 pinout, S6J342AJTBSE20000 application, or S6J342AJTBSE20000 equivalent, key selection criteria include CAN FD channel count, partial wake-up current, flash retention (20 years), 125 °C operation, and TEQFP-176 package compatibility with automotive thermal and EMI requirements.
Technical Context
This MCU implements a dual-core Arm Cortex-R5F with lockstep capability, integrated PLL0 with spread-spectrum clock generation, and three independent power domains for fine-grained energy management. It features hardware-accelerated SHE for secure boot and cryptographic operations, alongside ECC-protected CAN FD RAM (16 KB/channel).
The device uses a hierarchical bus architecture: HPM (33 MHz) for CPU and flash access, LLPM (33 MHz) for peripherals, and resource clock (up to 40 MHz) for timers and ADC. Its 64-channel ADC supports simultaneous sampling with programmable trigger sources including timer, MFS, and external pins.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1K | 32-bit RXv2 core (not Arm), 120 MHz max, 4 CAN FD channels, no integrated SHE | Lacks hardware security module; requires external crypto IC for secure boot | Preferred where legacy Renesas toolchain and CAN FD + LIN mix are prioritized over ASIL-B-certified security |
| S32K344 | Arm Cortex-M7 core, 200 MHz, 4 CAN FD, 2 MB flash, AURIX-style safety mechanisms | Higher performance but larger footprint; lacks TEQFP-176 package option | Selected when higher compute throughput is needed for OTA updates or complex diagnostics, with flexible package trade-offs |
Compared with RH850/F1K and S32K344, S6J342AJTBSE20000 uniquely balances ASIL-B-certified SHE, 6 CAN FD channels, and TEQFP-176 thermal performance-making it optimal for space-constrained, security-aware body domain controllers.
