It's built for deterministic control loops—CANbus, SCI, SPI, and I2C all on the same die—so a single chip handles the gateway, sensor fusion, and actuator drive in an industrial controller or automotive body module. The 59 I/O lines and external bus interface (EBI/EMI) leave room for memory expansion or parallel peripherals without a CPLD. ## 384 KB Flash and 16-bit datapath — firmware headroom 384 KB of program Flash is generous for a 16-bit MCU in this class—enough for a CANopen stack, several PID loops, and a bootloader with OTA staging. The HCS12X core's single-cycle multiply and XGATE co-processor offload interrupt-heavy tasks, so the main loop doesn't stall on CAN message handling. If your firmware footprint is already pushing 256 KB, this part gives breathing room without a die-shrink migration. ## CANbus, SCI, SPI — connectivity set for body control and industrial gateway The S912XES384J3CAA includes CANbus, SCI (UART), SPI, and I2C, plus an IrDA module. In a typical automotive body controller, CAN handles the vehicle network, SCI talks to a Bluetooth module or debug port, and SPI drives an external CAN transceiver or sensor hub. The EBI/EMI interface lets you attach an external SRAM or FRAM without bit-banging GPIO—useful for data logging in motor-drive applications. ## Temperature grade and environment The operating supply range is 1.72 V nominal, which means a single 1.8 V rail can power the core and I/O, simplifying the power tree. ## Lifecycle and sourcing Listed as Active by NXP—no EOL notice, no LTB window.","metaTitle":"NXP S912XES384J3CAA HCS12X 16-bit MCU, 384KB Flash, 50 MHz","metaDescription":"NXP S912XES384J3CAA HCS12X 16-bit MCU with 384KB Flash, 50 MHz core, CANbus/SCI/SPI, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"HCS12X","has_mpn":"S912","cpu_core":"HCS12X","frame_size":"16-Bit","fuse_speed":"50 MHz","connectivity":"CANbus, EBI/EMI, I2C, IrDA, SCI, SPI","package_type":"Bulk","Number Of I/O":"59","mounting_type":"Surface Mount","product_status":"Active","Data Converters":"A/D 12x12b SAR","Oscillator Type":"External","lifecycle_stage":"eol_hot","peripheral_types":"LVD, POR, PWM, WDT","supply_voltage_v":"1.72","Program Memory Type":"FLASH","Operating Temperature High":"-40°C to 85°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.32","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/74dac71c3c15439d9c932f8446cf9054.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does S912XES384J3CAA have CANbus support?","answer":"Yes—the S912XES384J3CAA includes a CANbus module as part of its connectivity set, alongside SCI, SPI, I2C, and IrDA.
