Product data sheet

SC68C752B_2

Modiﬁcations:

• added HVQFN32 package option (affects Section 1 “General description”, 3rd paragraph; Table 1

“Ordering information”; Section 5.1 “Pinning”; Section 5.2 “Pin description”; Section 12 “Package

outline”)

• Section 6.3.3.1 “Assumptions”, second paragraph:

– 1st sentence: changed “RCV FIFO” to “RX FIFO”

– 3rd sentence: changed “0F” to “0Fh”

– 6th sentence: changed “0D” to “0Dh”

• changed Xoff1, Xoff2, Xon1, Xon2 register names to XOFF1, XOFF2, XON1, XON2, respectively

(Xoff1, Xoff2, Xon1, Xon2 character and word names remain as-is)

• Table 10 “Register map - read/write properties”, Table note 4: changed “xBF” to “BFh”

• Table 11 “SC68C752B internal registers”: IER[7:4], FCR[5:4], IIR[5:4], MCR[5:4], LSR[7] bit

descriptions modiﬁed (removed “0/” and “0/X”)

• Table 24 “Register programming guide” modiﬁed: appended “h” to hex numbers

• Table 26 “Static characteristics”: changed “f(i)XTAL1: input clock frequency” to “fXTAL1: frequency on

pin XTAL1”

• Table 27 “Dynamic characteristics”:

– changed “fXTAL: clock speed” to “fXTAL1: frequency on pin XTAL1”

– changed “t1w, t2w” to “tw1, tw2”

– Table note 3: changed “t3w” to “tw3”

• Figure 17 “External clock timing” modiﬁed:

– “t1w, t2w, t3w” changed to “tw1, tw2, tw3”

– changed “fXTAL” to “fXTAL1” in the equation
