Difference between TL16C752D and TL16C752B

Other Parts Discussed in Thread: TL16C752D, TL16C752D-Q1

        

Dear Technical Support Team,

 

I have some question about TL16C752DPFBR and TL16C752BPT.

I'd like to replace from TL16C752BPT to TL16C752DPFBR, because TL16C752BPT is EOL.

 

1.)

"Delay from IOW to set TXRDY" has a large different specification between TL16C752D and TL16C752B.

Is following specification correct?

 

TL16C752B ⇒ max.70μs

TL16C752D ⇒ max.50ns

 

2.)Unit of "Delay from stop to set interrupt"

 

TL16C752B ⇒ 1Rclk

TL16C752D ⇒ 1baudrate

 

What the meaning of the Rclk of TL16C752B?

For example 19200bps, 1baudrate means 1/19200 = 52μs on TL16C752D?

 

3.) following specifications are defined on TL16C752B,

    but these are not defined on TL16C752D.

    How do I think about them?

    Are following specifications same between TL16C752B and TL16C752D?

  

   ・IOR delay from chip select (min.) → 0ns on TL16C752B, so is it deleted from TL16C752D?

   ・Chip select hold time from IOR (min.) → 0ns on TL16C752B, so is it deleted from TL16C752D?

   ・Chip select hold time from IOW (min.) → 0ns on TL16C752B, so is it deleted from TL16C752D?

   ・Hold time from XTAL 1 clock to to IOW or IOR release (min.)

   ・Setup time from IOW or IOR assertion to XTAL 1 clock (min.)

   ・Delay between successive assertion of IOW and IOR (max)

 

Best Regards,
