Package size = 17.9mm x 23.9mm.
Lead pitch = 0.65mm,
Body Size = 14mm x 20mm,
Serial Lines 0-7 (TTL compatible with internal pullups in the range 25 - 125k Ω ).
Bidirectional, time division multiplexed serial streams. According to mode selected by
MD0-2 inputs, distinct data rates can be selected at the serial port. In mode 3, these lines
are configured as inputs only. In modes 1, 2, 4 and 5, these lines become bidirectional.
Serial Lines 8-15 . See description for S0-S7 above. In mode 3, S8-S11 are inputs and
S12-S15 are outputs. In modes 1, 2, 4 and 5 these are bidirectional lines.
Serial Lines 16-23. See descripton for S0 - S7 above. For mode 3, these lines are outputs
and operate at 8.192 Mb/s rates. When operating in modes 1, 2, 4 and 5, these lines are
bidirectional.
Boundary Scan Test Data Output.
Read P0-P7 input clock . This input is used by the MT90210 to sample bytes coming in at
the parallel port P0-P7 lines. Typically, the user should connect CKout to this input.
Serial Port Output Enable (Input). On the parallel-to serial conversion direction, this input
is used by the MT90210 to know which time-slots on the serial output streams will be
placed in high-impedance. This input is sampled synchronously along with the parallel
input data before the parallel-to-serial conversion takes place. When low, output serial
channels are actively driven. When set high, the output bus drivers are disabled.
