PCD46x1A line of controller chips to replace existing PCD lineApr 25, 2016
RADFORD, Va. - Nippon Pulse has released a new line of PCD controller chips as an upgrade for the PCD46x1 series. The new 46x1A series includes updates and new features.
The new series contains three chips: the single-axis PCD4611A, the two-axis PCD4621A and the PCD4641A, a four-axis chip. The chip package and terminal allocation of all three chips remain the same as those in the previous series, with QFPs of 48 pins, 64 pins and 100 pins, respectively. They can also be mounted on the same boards as the previous chips.
PCD46x1 had a circuit bug that prevented a motor from starting when a start command is programmed after a stop command. This bug has been fixed in the new series, and the procedures for writing the commands have been adjusted to prevent future issues. New features include the capability for a CPU to connect to the chips with either an 8-bit parallel bus connection or a 4-wire serial interface; when connecting with the latter, terminals D0 through D5 can be used as general-purpose input/output ports.
The PCD46x1A series is available for all new applications as Nippon Pulse transitions away from the PCD46x1 series. The PCD46x1 chips will still be available for purchase as Legacy products through December 2017.
For more information about the corrected command procedures, as well as other adjustments that have been made between the two series, check out the PCD46x1A user's manual.
