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 reference design can be utilized directly or integrated into a
larger printed wiring board. A further benefit is the compactness of the
circuit layout. Power-driver output ratings presently available with these
devices are 50 V and
±1.5 A (with the A3955 or A3957). A similar
device for 46 V and either 1.5 A (with the SLA7042M) or 3 A (with the
SLA7044M) is planned. The reference design supports stepping formats
that include full-step, half-step, quarter-step, eighth-step, and sixteenth-
step (microstepping) increments for a two-phase stepping motor.
The A4255CA is furnished in an 18-pin dual in-line plastic package
for through-hole applications. The A4255CLN is furnished in a 20-lead
wide-body, shrink-pitch, small-outline plastic package (SSOP) with gull-
wing leads for minimum area, surface-mount applications.
