Upgraded Motion-Control IC Replaces HCTL-1100

The MCP-1200 was developed to easily replace existing designs using the HCTL-1100, which is being obsoleted by its manufacturer. The backwards-compatible and plug-in ready device is a single-axis motion-control solution for both servo and stepper motors that can be synchronized with multiple chips for multi-axis applications. New and existing applications can take advantage of a new set of powerful motion-control features by enabling the chip’s enhanced mode. No expertise in motion-control algorithms or servo control is necessary to implement a high-performance servo control system. All the low-level fast computations are performed on the MCP-1200, freeing up the host micro-controller for supervisory tasks. No external memory is required, just an incremental encoder to provide position feedback. The chip outputs a 12-bit analog or PWM signal to control the motor drivers. The MCP-1200 is available for immediate delivery in the PLCC 44-lead package at a price point of $16.10 for 1000 pieces. A QFN-44 package measuring only 7- by 7-mm is also in the works.
