TMC457 DATASHEET (V. 1.16 / 2009-Nov-25)
9 Pinning, Package, and Electrical data of the TMC457
9.1 Pinning of TMC457
The TMC457-BC is available within a 144 ball fine pitch (1 mm) BGA package.
Important Hints:
All pins specified as (n.c. = not connect) must be left unconnected (open). All power supply pins
(named V33 for +3.3V and named V15 for +1.5V) and all ground pins must be connected.
All inputs and all outputs have 3.3V CMOS level. Level shifters are required when using 5V
devices (e.g. micro controller with 5V IO, incremental encoder with 5V ABN outputs, …).
Other unnamed pins have to be left open. Pins with comment "do not connect (must not be
connected)" must be left open because these are unused but driving outputs.
