Product details
Overview
S6J311AHACSE20000 from Infineon Technologies (formerly Cypress) is a 32-bit automotive-grade microcontroller based on the Arm® Cortex®-R5 CPU, featuring 1024 KB + 64 KB program flash, 64 KB TCRAM, and CAN-FD support up to 5 Mbps. It operates at 96 MHz, includes dual 12-bit ADCs (56 total channels), and targets in-vehicle body control modules requiring functional safety and real-time determinism.
For engineers reviewing the S6J311AHACSE20000 datasheet, S6J311AHACSE20000 pinout, S6J311AHACSE20000 application, or S6J311AHACSE20000 equivalent, key selection criteria include Cortex-R5 core with SEC-DED ECC on TCM ports, LEU144 package compatibility, 5 V single-supply operation with internal 1.2 V regulation, and integrated LIN-UART/CAN-FD for automotive networked subsystems.
Technical Context
The S6J311AHACSE20000 implements a dual-issue superscalar Armv7/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 deterministic peripheral access. Its TCM architecture includes separate ATCM and BTCM ports with ECC protection enabling 1-bit correction and 2-bit detection.
Peripheral integration centers on automotive I/O consolidation: four multi-function serial channels (I²C, UART, CSIO, LIN-UART), one CAN-FD controller with 192 Rx/32 Tx message buffers, 30-channel 16-bit base timers with PWM/PPG/PWC modes, and RTC with CR clock calibration using prescaler ratio adjustment against main oscillator drift.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1K | 32-bit RXv2 core (not Arm), 1.5 MB flash, no CAN-FD, supports CAN FD via external IP | Lacks native CAN-FD; requires additional logic for 5 Mbps data phase handling | Select when legacy Renesas toolchain and ASIL-B certification path are prioritized over CAN-FD integration |
| S32K144 | Arm Cortex-M4F core, 512 KB flash, 64 KB SRAM, CAN-FD, but no Cortex-R5 safety features or TCM ECC | No MPU region enforcement or SEC-DED TCM-requires software mitigation for memory corruption | Select for cost-sensitive entry-level body ECUs where ASIL-B compliance is achieved via SW layering rather than hardware-enforced isolation |
Compared with RH850/F1K and S32K144, the S6J311AHACSE20000 delivers hardware-enforced functional safety through Cortex-R5's MPU and ECC-protected TCM, native CAN-FD with full 5 Mbps support, and larger flash/RAM for AUTOSAR Classic scalability-making it optimal for mid-tier BCMs requiring ASIL-B compliance without external safety co-processors.

FAQ
What is the maximum operating frequency and supported voltage range for S6J311AHACSE20000?
The S6J311AHACSE20000 operates at a maximum CPU frequency of 96 MHz and requires a single 5 V supply with tolerance of ±10% (4.5 V to 5.5 V). Internal voltage regulation generates a stable 1.2 V core supply from this input, eliminating need for external DC-DC converters in most automotive body applications.
Does S6J311AHACSE20000 support functional safety standards like ISO 26262?
Yes-the S6J311AHACSE20000 incorporates hardware safety mechanisms including ECC on TCM ports (SEC-DED), MPU with 16 configurable memory regions, lockstep-capable peripherals, and built-in self-test (BIST) for flash and RAM. These features enable ASIL-B compliance when implemented per Infineon's safety manual and certified toolchain.
How many CAN-FD message buffers does S6J311AHACSE20000 provide, and what is their allocation?
The device provides 192 receive message buffers and 32 transmit message buffers per CAN-FD channel. Buffers are organized in dedicated RAM sections with configurable filtering and priority arbitration, supporting flexible mailbox assignment for mixed diagnostic (UDS) and control (CANopen) traffic on the same bus.
Is external crystal required for real-time clock operation, or can the internal CR oscillator be used alone?
The RTC can operate solely on the internal 100 kHz CR oscillator, with optional calibration using the 4 MHz main oscillator to correct drift. No external crystal is required-enabling reduced BOM count and improved reliability in vibration-prone automotive mounting locations.
