Microchip Technology Inc.
HQ US
Chandler, Arizona-based semiconductor company (NASDAQ: MCHP); one of the world's largest makers of microcontrollers and DSP controllers. dsPIC33 Digital Signal Controllers (DSCs) are widely used in agricultural implement controllers, seed metering drives, hydraulic valve controllers, and rate controllers. dsPIC33 combines MCU simplicity with DSP signal processing for real-time control loops — the exact profile needed in ISOBUS-connected implement ECUs. dsPIC33A (latest generation): low latency, high-performance, motor control, fans, pumps. dsPIC33C (dual-core): for safety-critical control. New integrated motor drivers combine dsPIC DSC with gate drivers and communications in a single package — reducing bill-of-materials for agricultural implement controllers. Microchip is also a major producer of CAN bus controllers and protocol chips complementing NXP transceivers in ag ECU designs.
