A4255CA 8-BIT MICROCONTROLLER

To ease and simplify the design effort, the user only provides the following signals: (a) direction, (b) stepping clock (8x the full-step frequency), (c) mode logic (three inputs determine the operation for full, half, quarter, or eighth stepping), (d) reset input (initiates a ‘detent’ position), an.

4255 A4255CA 8-BIT MICROCONTROLLER The A4255CA and A4255CLN microcontrollers make designing with step motors easy, inexpensive, and productive. A reference design technique is integral to the implementation of a system that includes the power circuitry, a low-cost, 8-bit, preprogrammed microcontroller and the other components needed to complete the control hardware. The A4255Cx eliminates the need for software development, expedites the product creation, and hastens the time to market. The refe.
