Product Overview
The SERCON816 is an industrial SERCOS I/II motion control ASIC from STMicroelectronics. It acts as an independent slave controller to offload real-time bus processing from host MCUs or DSPs.
This chip implements full SERCOS physical & data link layers, supporting fiber/electrical transmission with microsecond-level synchronous accuracy. Its built-in 2048×16-bit dual-port RAM enables fast data interaction with external processors, alongside hardware cycle timing, ring repeater and watchdog error detection. Housed in PQFP-100 packaging with strong EMI resistance, it serves CNC machine tools, industrial robots, printing equipment and servo drive systems.
Core Advantages
Ultra-Precise Deterministic Synchronization
Natively embeds hardware timing recovery loops to synchronize multi-axis servo drivers with sub-microsecond jitter, supporting stable simultaneous motion control.
Dedicated Processor Load Offloading
Independently completes SERCOS protocol parsing, timing scheduling and cyclic data transmission, reducing host MCU/DSP operation burden for motion path calculation.
Large Integrated Dual-Port RAM Architecture
Built-in 2048 × 16-bit dual-port RAM interface supports asynchronous high-speed read-write with host, eliminating communication delay and waiting state.
Multi-Topology Industrial-Grade Noise and EMI Immunity
Supports fiber optic ring, RS485 ring and bus connection to achieve full electrical isolation, effectively resist high-voltage electromagnetic interference in factory environments.
Built-in Hardware Watchdog & Ring Repeater
Integrated watchdog monitors system operation status; internal repeater supports long-distance daisy-chain ring layout without extra signal amplifiers.

Frequently Asked Questions
Q1: Is your currently available inventory of the SERCON816 controller 100% authentic and original ST stock?
A: Yes, we guarantee that all SERCON816 communication ASICs in our warehouse are 100% brand-new, factory-original components directly from STMicroelectronics. Each lot undergoes strict tracking checks and is delivered in original secure anti-static trays to guarantee component lead coplanarity.
Q2: What primary system function does the SERCON816 fill in a multi-axis servo drive framework?
A: The SERCON816 acts as an intelligent serial slave node. It receives real-time position, speed and torque commands from the master CNC/PLC via SERCOS fiber ring, parses data by hardware and stores data into internal dual-port RAM, enabling motor control DSP to access data without protocol overhead.
Q3: Why does the SERCON816 utilize fiber-optic lines for its serial data layer connections?
A: Fiber cables provide full electrical isolation and eliminate EMI, surge interference and ground loop issues in factory environments, ensuring long-distance stable error-free data synchronization. The chip’s built-in repeater supports extended ring topology layout.
