Product details
Overview
S6J311EJAASE1000A 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 CAN-FD (2 channels, 1 Mbps), and features dual 12-bit ADCs with 64 total channels.
For engineers reviewing the S6J311EJAASE1000A datasheet, S6J311EJAASE1000A pinout, S6J311EJAASE1000A application, or S6J311EJAASE1000A equivalent, key selection criteria include its Cortex-R5 core with SEC-DED ECC on TCM ports, LIN-UART v2.1 support, hardware/software watchdogs, RTC with CR clock calibration, and LEP176 package compatibility for automotive ECU designs.
Technical Context
The S6J311EJAASE1000A 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 AXI master/slave interfaces for high-bandwidth peripheral access. Its TCM architecture includes separate ATCM and BTCM ports with ECC protection (SEC-DED) for safety-critical code execution.
Peripheral integration centers on deterministic real-time I/O: two CAN-FD controllers (192 Rx/32 Tx message buffers per channel), 22 multi-function serial channels (I²C, UART, CSIO, LIN-UART), six 32-bit free-run timers, and a 30-channel 16-bit base timer supporting PWM, PPG, PWC, and reload modes - all synchronized to a 4 MHz main clock or 100 kHz CR oscillator.

FAQ
What is the maximum operating temperature range for S6J311EJAASE1000A?
The S6J311EJAASE1000A is qualified per AEC-Q100 Grade 2, supporting continuous operation from −40°C to +105°C ambient temperature. This rating applies to the full LEP176 package and all integrated peripherals, including CAN-FD, LIN-UART, and ADC subsystems, under specified voltage and load conditions.
Does S6J311EJAASE1000A support secure boot with cryptographic verification?
Yes - the device integrates a Secure Hardware Extension (SHE) engine compliant with ISO/SAE 21434 and EVITA Medium profiles. It supports AES-128 encryption, SHA-256 hashing, and asymmetric key operations required for authenticated secure boot, enabling firmware signature verification before execution.
Can the S6J311EJAASE1000A operate without an external crystal?
Yes - it includes an internal 100 kHz CR oscillator and a 4 MHz CR oscillator, both usable as clock sources. The 100 kHz CR clock can drive the RTC and system clock during crystal failure, and the clock supervisor automatically switches to CR mode if main crystal oscillation fails - ensuring fail-operational behavior.
How many independent CAN-FD message buffers are available in total?
The S6J311EJAASE1000A provides 384 total CAN-FD message buffers: 192 reception and 32 transmission buffers per channel across two independent CAN-FD controllers. Buffers are configurable in size and priority, and support hardware timestamping and FIFO-based interrupt handling for deterministic message processing.
