TPIC5404DW Datasheet The device offers accelerated program operations through the ACC function. This is one of two func- tions provided by the WP#/ACC pin. This function is primarily intended to allow faster manufacturing throughput at the factory. If the system asserts VHH (11.5~12.5V) on this pin, the device automatically enters the previously mentioned Unlock Bypass mode, temporarily unprotects any protected sec- tors, and uses the higher voltage on the pin to reduce the time required for program operations. Only two-cycle program command sequences are required because the unlock bypass mode is auto- matically activated in this acceleration mode. The device returns to the normal operation when VHH iS removed from the WP#/ACC pin. It should be noted that the WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. In addition, the WP#/ ACC pin must not be left floating or unconnected; inconsistent or undesired behavior of the device may result. TPIC5404DW Price
TPIC5404DW on stock In addition to the Utopia Interface signals, error indication signals are available for error monitoring or statistics. An error indication always shows that a cell has been discarded by the bridge. Possible errors are parity or cell-length errors on the receive interface of the corresponding Utopia Interfaces.
