Product details
Overview
S6J311EHACSE20000 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-R5 automotive microcontroller designed for in-vehicle real-time control applications. It operates at up to 144 MHz, integrates 4096 KB + 64 KB program flash and 256 KB system SRAM, supports dual CAN-FD channels (1 Mbps, 192 message buffers per channel), and targets body control modules and domain controllers requiring functional safety support.
For engineers reviewing the S6J311EHACSE20000 datasheet, S6J311EHACSE20000 pinout, S6J311EHACSE20000 application, or S6J311EHACSE20000 equivalent, key selection criteria include Cortex-R5 core with SEC-DED ECC on TCM ports, LIN-UART v2.1 compliance, 12-bit dual A/D converters (64 total channels), and LEP176 package compatibility with automotive-grade thermal and EMI requirements.
Technical Context
The S6J311EHACSE20000 implements a dual-issue superscalar Arm v7/Thumb-2 Cortex-R5 core with 16 KB instruction and 16 KB data caches, MPU supporting 16 memory regions, and TCM ports (ATCM/BTCM) with SEC-DED ECC protection. Its AXI master interface provides 64-bit instruction/data access and 32-bit I/O access, enabling deterministic low-latency peripheral interaction.
Peripheral integration includes two CAN-FD controllers compliant with ISO 11898-1:2015 (V3.2.0), 22-channel multi-function serial (I²C, UART, CSIO, LIN-UART), 12-bit successive-approximation ADCs with 64 total input channels, and a clock supervisor that enables automatic failover from 4 MHz main oscillator to 100 kHz CR oscillator upon crystal fault detection.

FAQ
What is the maximum operating temperature range for S6J311EHACSE20000?
The S6J311EHACSE20000 is qualified to AEC-Q100 Grade 2, with an operating junction temperature range of –40°C to +105°C. This rating is validated per JEDEC JESD22-A104 and applies to continuous operation under specified voltage and load conditions in automotive environments.
Does S6J311EHACSE20000 support JTAG debugging in production mode?
Yes - JTAG (TMS/TCK/TDI/TDO) remains fully accessible in production mode, but debug access is gated by flash security settings. When SHE is enabled and debug lock bits are set, JTAG enters secure mode and restricts memory readout while permitting breakpoint-based code validation and functional testing.
How many CAN-FD message buffers are allocated per channel?
The S6J311EHACSE20000 allocates 192 message buffers for reception and 32 message buffers for transmission per CAN-FD channel. These buffers are configurable via register-based message object setup and support flexible ID filtering, masking, and priority arbitration per ISO 11898-1:2015.
Is external RAM required for typical automotive applications?
No - the integrated memory subsystem (64 KB TCRAM, 256 KB system SRAM, 64 KB backup RAM) satisfies typical body control application requirements. External RAM is unnecessary unless implementing large OTA update staging buffers or high-resolution graphics framestores, which fall outside this MCU's target use cases.
