Product Summary

The LM628N-8 is a dedicated motion-control processor designed for use with a variety of DC and brushless DC servo motors, and other servomechanisms which provide a quadrature incremental position feedback signal. The LM628N-8 performs the intensive, real-time computational tasks required for high performance digital motion control. The host control software interface is facilitated by a high-level command set. The LM628N-8 has an 8-bit output which can drive either an 8-bit or a 12-bit DAC.

Parametrics

LM628N-8 absolute maximum ratings: (1)Voltage at Any Pin with Respect to GND: -0.3V to +7.0V; (2)Ambient Storage Temperature: -65℃ to +150℃; (3)Lead Temperature, 28-pin Dual In-Line Package (Soldering, 4 sec.): 260℃; 24-pin Surface Mount Package (Soldering, 10 sec.): 300℃; (4)Maximum Power Dissipation (TA ≤ 85℃): 605 mW; (5)ESD Tolerance (CZAP = 120 pF, RZAP = 1.5k): 2000V.

Features

LM628N-8 features: (1)32-bit position, velocity, and acceleration registers; (2)Programmable digital PID filter with 16-bit coefficients; (3)Programmable derivative sampling interval; (4)8- or 12-bit DAC output data (LM628); (5)8-bit sign-magnitude PWM output data (LM629); (6)Internal trapezoidal velocity profile generator; (7)Velocity, target position, and filter parameters may be changed during motion; (8)Position and velocity modes of operation; (9)Real-time programmable host interrupts; (10)8-bit parallel asynchronous host interface; (11)Quadrature incremental encoder interface with index pulse input; (12)Available in a 28-pin dual in-line package or a 24-pin surface mount package (LM629 only).
