Introduction
This manual describes the operational characteristics of the MC2542, MC2522 and MC2512 Motion Processors from PMD. These devices are members of PMD’s second-generation motion processor family, which consists of 17 separate products organized into 6 series.

Each of these devices is a complete chip-based motion processor. They provide trajectory generation and related motion control functions, and high speed pulse and direction outputs. Together these products provide a software-compatible family of dedicated motion processors that can handle a large variety of system configurations.

Each of these chips utilize a similar architecture, consisting of a high-speed computation unit, along with an ASIC (Application Specific Integrated Circuit). The computation unit contains special onboard hardware that makes it well suited for the task of motion control.

Each chipset consists of two PQFP (Plastic Quad Flat Pack) ICs: a 100-pin Input/Output (I/O) chip, and a 132-pin Command Processor (CP) chip.

Four of the series in the Navigator family are designed for a particular type of motor or control scheme. The fifth allows the user to control 2 servo motor types (brushed and brushless). Here is a summary description of each series.
