Differences among 32-pin, 36-pin and 42-pin
The 7534 Group has three package types, and each of the number
of I/O ports are different. Accordingly, when the pins which have the
function except a port function are eliminated, be careful that the
functions are also eliminated.

7532/7536 Group
Not deal with the host which performs the Control
transfer in parallel to plural device.
USB function can be used only at the condition of
CL = 150 pF to 350 pF.
Rating is Max. 300
A not including the output cur-
rent of USBVREFOUT.
ACK is returned once to OUT (DATA0) to be valid
in Status stage.
SYNC is detected only when 8-bit full code (8016)
is complete.
7534 Group
Connectable to the host which performs the Con-
trol transfer in parallel to plural device.
Deal with the the following USB Spefification Rev.
1.1.
CL = 200 pF to 450 pF,
Trise and Tfall: 75 ns to 300 ns,
Tr/Tf: 80 % to 125 %,
Cross over Voltage: 1.3 V to 2.0 V.
Rating is Max. 300
A including the output current
of USBVREFOUT, by low-power dissipation of D+/
D- input circuit and 3.3 V-regulator.
STALL is set automaticcally by hardware when
OUT (DATA0) is received in Status stage.
SYNC is detected only the low-order 6 bits even if
the high-order 2 bits are corrupted.
