Product details
Overview
S6J337AHTBSE20000 from Infineon Technologies (formerly Cypress) is an automotive-grade 32-bit Arm® Cortex®-R5F microcontroller designed for digital instrument cluster control. It operates at up to 132 MHz, integrates 2,112 KB TC-Flash and 128 KB TC-RAM, supports CAN FD (4 channels), and meets ASIL-B per ISO 26262 for use in speedometer, tachometer, fuel gauge, and temperature meter systems.
For engineers reviewing the S6J337AHTBSE20000 datasheet, S6J337AHTBSE20000 pinout, S6J337AHTBSE20000 application, or S6J337AHTBSE20000 equivalent, key selection criteria include its dual-voltage operation (3.3 V/5 V), 144-pin LQFP package with 94 GPIOs, AEC-Q100 qualification, -40 °C to +105 °C operating range, and integrated Secure Hardware Extension (SHE) for secure boot and cryptographic operations.
Technical Context
The S6J337AHTBSE20000 implements a lockstep-capable Arm Cortex-R5F core with MPU, TPU, ECC-protected memory, and dual power domains (PD1/PD2/PD4) for functional safety partitioning. Its peripheral set includes four CAN FD controllers with 16 KB ECC RAM per channel, a 12-bit 40-channel ADC, six base timers, and eight free-run timers - all synchronized to support deterministic real-time response in cluster display subsystems.
It integrates dedicated hardware accelerators for LCD control (4 COM × 32 SEG), stepper motor control (6 gauges), sound generation (PCM-PWM, I2S, mixer), and security (SHE module with fixed MK_CEER enable). Clock management includes PLL0/Expand PLL/SSCG0, JTAG debug interface, and boot ROM with CRC-verified firmware loading.

FAQ
What is the maximum operating frequency of the Arm Cortex-R5F core in S6J337AHTBSE20000?
The Arm Cortex-R5F core operates at up to 132 MHz, verified 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 supports deterministic interrupt latency for cluster UI responsiveness.
Does S6J337AHTBSE20000 support CAN FD with bit rate switching?
Yes - it integrates four independent CAN FD controllers supporting flexible data-rate (FDR) with arbitration phase up to 1 Mbps and data phase up to 5 Mbps. Each channel includes dedicated 16 KB ECC-protected RAM for message buffering and filtering.
How is the Secure Hardware Extension (SHE) configured in this part number?
S6J337AHTBSE20000 has MK_CEER fixed to Enable (per ordering code 'E' in position 10), meaning the SHE module is permanently activated at power-on. It supports AES-128 encryption, SHA-256 hashing, and secure key storage with tamper-resistant protection for secure boot and OTA firmware validation.
What LCD interface modes does the S6J337AHTBSE20000 support?
It supports direct 4 COM × 32 SEG static/dynamic LCD drive with programmable bias and frame frequency. No external bias generator or segment driver IC is required. The interface operates independently of the CPU core via dedicated DMA and timer resources for flicker-free, low-CPU-load display updates.
