Product details
Overview
S6J311DHACSE20000 from Infineon Technologies (formerly Cypress) is a 32-bit automotive-grade microcontroller based on the Arm® Cortex®-R5 CPU core, operating at up to 144 MHz with 3072 KB + 64 KB program flash, 192 KB system SRAM, and dual 12-bit ADCs (64 total channels). It integrates two CAN-FD controllers (1 Mbps), 22 multi-function serial channels (UART/I²C/CSIO/LIN), and supports in-vehicle body control modules requiring functional safety and real-time deterministic execution.
For engineers reviewing the S6J311DHACSE20000 datasheet, S6J311DHACSE20000 pinout, S6J311DHACSE20000 application, or S6J311DHACSE20000 equivalent, key selection criteria include CAN-FD channel count, flash/RAM partitioning, LEP176 package compatibility, RTC calibration via CR oscillator, and SHE security option status for automotive ASIL-B–capable designs.
Technical Context
The S6J311DHACSE20000 implements a dual-issue superscalar Arm v7/Thumb-2 Cortex-R5 core with 16 KB instruction and 16 KB data caches, SEC-DED ECC on TCM ports, and AXI master/slave interfaces for high-bandwidth peripheral access. Its memory subsystem includes 3072 KB + 64 KB program flash, 192 KB system SRAM, 64 KB TCRAM, and 64 KB backup RAM - all mapped to a deterministic memory map supporting lockstep-ready configurations.
Peripheral integration centers on real-time I/O control: two CAN-FD controllers (192 RX/32 TX message buffers per channel), 30 base timers (PWM/PPG/PWC/reload), six 32-bit free-run timers, and 22 configurable serial interfaces with 64-byte FIFOs and DMA support (ch.0–ch.7 only). Clock supervision monitors 4 MHz main crystal failure and auto-switches to 100 kHz CR oscillator with RTC calibration capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S6J311EHACSE20000 | 4096 KB + 64 KB program flash, 256 KB system SRAM, SHE security enabled | Required where secure boot, cryptographic acceleration, or OEM key provisioning is mandated | Select when ASIL-B certification requires hardware-enforced secure boot and key storage |
| R7F701684 | Renesas RH850/F1L core, 120 MHz, 2 MB flash, no CAN-FD, LIN-only serial interface | Limited to legacy LIN-based body networks without CAN-FD upgrade path | Choose only for cost-sensitive LIN-only modules where CAN-FD bandwidth is unnecessary |
Compared with S6J311EHACSE20000, this part trades flash capacity and SHE for lower BOM cost and reduced security overhead; versus R7F701684, it delivers CAN-FD readiness and higher ADC channel count but requires more complex power sequencing and thermal management.

FAQ
What is the maximum operating frequency and supported voltage range?
The S6J311DHACSE20000 operates at up to 144 MHz with a single 5 V ±10% supply. Internal regulation generates 1.2 V for the core, while I/O circuits run directly from 5 V. Absolute maximum ratings specify VDD = 5.5 V and operating temperature from −40 °C to +125 °C ambient, validated per AEC-Q100 Grade 2.
Does this part support JTAG debugging and flash programming?
Yes - the device supports standard JTAG interface (TCK/TMS/TDI/TDO/nTRST) for boundary scan, debug, and flash programming. Pin assignment confirms dedicated JTAG signals on Port 0, and the datasheet specifies JTAG tool connection procedures including voltage level matching and pull-up resistor requirements.
How many CAN-FD message buffers are allocated per channel?
Each of the two CAN-FD channels provides 192 message buffers for reception and 32 message buffers for transmission. Buffer allocation is configurable via register settings, and the hardware supports automatic message filtering, priority arbitration, and error frame handling per ISO 11898-1:2015.
Is RTC calibration supported, and how is it implemented?
Yes - RTC calibration uses the 100 kHz CR oscillator as reference to correct drift in the main 4 MHz crystal oscillator. The calibration ratio is computed in firmware and applied to the RTC prescaler register, enabling ±1 ppm accuracy over temperature and aging - documented in Section 1.4.3 and Section 10.9 of the datasheet.
