Product Summary

The LM629M-6 is a dedicated motion-control processor. It is 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 LM629M-6 has an 8-bit output which can drive either an 8-bit or a 12-bit DAC. The LM629M-6 is fabricated in NMOS and packaged in a 28-pin dual in-line package or a 24-pin surface mount package. Both 6 MHz and 8 MHz maximum frequency versions are available with the suffixes -6 and -8, respectively, used to designate the versions.

Parametrics

LM629M-6 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(Soldering, 4 sec.):260℃; (4)Maximum Power Dissipation:605 mW; (5)ESD Tolerance:2000V.

Features

LM629M-6 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-bit sign-magnitude PWM output data; (5)Internal trapezoidal velocity profile generator; (6)Velocity, target position, and filter parameters may be changed during motion; (7)Position and velocity modes of operation; (8)Real-time programmable host interrupts; (9)8-bit parallel asynchronous host interface; (10)Quadrature incremental encoder interface with index pulse input; (11)Available in a 28-pin dual in-line package or a 24-pin surface mount package.
