A4255CA microcontroller equivalent, 8-bit microcontroller.
ABSOLUTE MAXIMUM RATINGS I I I I I I Full-, Half-, Quarter-, Eighth-, or Sixteenth-Step Increments DC to 20 MHz Clock Input Power-On Reset Brown-Out Reset High-Speed CMOS.
The A4255CLN is furnished in a 20-lead wide-body, shrink-pitch, small-outline plastic package (SSOP) with gullwing lead.
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), (.
