Global Industrial PLC & Motion Control Chip Supply Tightens Sharply, TI & ST Mainstream MCU/DSP Allocation Reduced by 40%, Spot Sourcing Becomes Main Procurement Method

Introduction

Driven by the continuous expansion of AI data center construction, major foundries continue to squeeze the wafer capacity of industrial control chips in Q3 2026. Texas Instruments and STMicroelectronics have cut the monthly wafer allocation of classic industrial DSP, general-purpose STM32 MCU and motor driver IC by about 40%. For mainstream models widely used in servo drives, frequency converters and PLC equipment, official channel lead times are generally between 24 and 38 weeks. Many automation equipment manufacturers cannot get stable supply quotas from authorized channels, and have to turn to the spot market for emergency material replenishment. However, the parallel spot market has problems such as mixed batches, refurbished goods and unstable pricing, which is easy to cause inconsistent product batch performance of automation equipment. LXBCHIP has long-term reserved full series spot inventory covering TI C2000 DSP, STM32 industrial MCU, isolated ADC and gate driver chips. All products are original factory packaging with complete traceability, with fixed and transparent pricing, supporting mixed bill of materials matching and global fast logistics delivery, becoming a stable supplementary supply channel for many automation manufacturers.

Conclusion

The shortage of industrial control core chips will not be alleviated before the end of 2026. Procurement departments should optimize purchasing strategies and reasonably allocate spot stock reserves to ensure the continuous progress of R&D and mass production.
