It integrates 2,112 KB TC-Flash, 128 KB TC-RAM, 128 KB System-RAM (including 24 KB backup), and supports 5 V or 3.3 V supply.

For engineers reviewing the S6J337BJSBSE20000 datasheet, S6J337BJSBSE20000 pinout, S6J337BJSBSE20000 application, or S6J337BJSBSE20000 equivalent, key selection criteria include CAN FD channel count (4), A/D converter resolution (12-bit, 48 channels), LCD controller support (4 COM × 32 SEG), real-time clock with automatic calibration, and dual-domain power management (PD1/PD2/PD4).

Technical Context

This MCU implements a dual-core lockstep-capable Arm® Cortex®-R5F CPU running at up to 132 MHz, with separate instruction and data caches (16 KB each), memory protection unit (MPU), and timer protection unit (TPU). It uses 40-nm CMOS technology and supports ISO 26262 ASIL-B functional safety via hardware mechanisms including ECC on RAM/Flash, watchdog timers, and clock supervision.

The device integrates four independent CAN FD controllers with 16 KB ECC-protected RAM per channel (equivalent to 128-message buffers), a 12-bit ADC with 48 input channels and partial wake-up capability, and a segment LCD controller supporting up to 4 COM × 32 SEG. Its multi-voltage architecture allows simultaneous 5 V and 3.3 V operation across I/O domains.

FAQ

What is the maximum operating frequency of the Arm® Cortex®-R5F core in S6J337BJSBSE20000?

The Arm® Cortex®-R5F core operates at up to 132 MHz under recommended conditions (VCC5 = 5.0 V ± 0.5 V, TA = -40 °C to 105 °C). This frequency is sustained across the full automotive temperature range and is verified per AEC-Q100 stress testing protocols. The core includes tightly coupled instruction and data caches (16 KB each) to maintain throughput at peak clock rate without memory bottlenecks.

Does S6J337BJSBSE20000 support CAN FD with ISO 11898-1:2015 compliance?

Yes, S6J337BJSBSE20000 integrates four fully compliant CAN FD controllers supporting ISO 11898-1:2015, including bit-rate switching, flexible data length (up to 64 bytes), and CRC-17/CRC-21 calculation. Each channel has dedicated 16 KB ECC-protected RAM, enabling 128-message buffer capacity per channel without CPU intervention.

How is the Secure Hardware Extension (SHE) implemented in this MCU?

SHE is implemented as a dedicated on-die cryptographic module compliant with ISO/IEC 15408 (CC EAL4+), providing AES-128 encryption/decryption, SHA-256 hashing, and secure key storage. It features a fixed MK_CEER register (enabled per part number S6J337BJSBSE20000), preventing unauthorized key erasure, and supports secure boot authentication using factory-programmed keys stored in tamper-resistant memory.

What LCD display configurations does the integrated segment controller support?

The integrated segment LCD controller supports up to 4 common (COM) lines and 32 segment (SEG) lines - enabling direct drive of 128-segment displays (e.g., analog-style gauges, bar graphs, alphanumeric characters). It includes programmable bias voltage generation, charge pump, and frame frequency control (20–120 Hz), eliminating need for external display drivers or external bias supplies.
