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

µA 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

µA 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.
