S912XET256J2VAG Microcontroller MCU 50MHz 16-Bit HCS12X Microcontroller IC LQFP-144

S912XET256J2VAG is a high-performance 16-bit automotive-grade microcontroller designed for automotive body control, in-vehicle networks, and industrial control applications. Based on the enhanced S12X core, it integrates an XGATE coprocessor, large-capacity Flash memory, multiple CAN/LIN/SCI communication interfaces, a high-precision ADC, and comprehensive system protection functions.

Designed specifically for high-reliability, high-real-time automotive electronic control units, it delivers near-32-bit computational performance while retaining the efficiency, low cost, and low power consumption advantages of a 16-bit MCU.

• Dual-core architecture with high-performance real-time processing: main CPU and XGATE coprocessor operate in parallel, with XGATE independently handling interrupts, communication, and I/O tasks
• High-reliability automotive-grade design: AEC-Q100 certification, ECC flash error correction, MPU protection, LVD/watchdog/clock monitoring
• Multi-protocol in-vehicle network support: Integrated dual CAN + dual LIN, directly supporting body domain network communication
• Large-capacity storage and efficient architecture: 256KB Flash + 16KB RAM + 4KB emulated EEPROM
• Extensive peripherals and I/O: 24-channel 12-bit ADC, multiple PWM/timers, and 119 GPIOs
• Low power consumption and wide voltage range: supports multiple low-power modes with wide voltage range compatible with 12V vehicle battery systems
