Preliminary
Corrected figure 2 pin diagram on pins 16 to 30 and 39.
Corrected pins description (pin number) for TX3, RX6, DSR6# and 16/68#.
Changed part number to XR16L788, added 5V spec and target timing, and corrected RX6 pin to be 39.
Changed Icc to 5mA max. and Isleep current to 400uA max, clarified ENIR pin and MCR bits 2 and 6.
Updated Electrical Specification Tables. Added θ-ja and θ-jc values. Removed Preliminary designation.
changed V_IL ( 0.8 to 0.7 max) and V_IH (2.2 to 2.4 min) in electrical characteristics tables.
Changed I_sleep max @ 3.3V from 0.40mA to 0.60 mA and @ 5V from 0.40 to 3.00mA
Deleted V_OH @ I_out =6mA. Changed condition on ICC from CLK=35MHz to “EXT Clock=2Mhz”. Changed
T_RDA from min =30ns to 35ns. Changed max V_OL @5V from 0.4 to 0.55V. Changed min V_OH @5V from
4.0 to 2.4V.
Updated values of AC Electrical Characteristics (T_AS, T_AH, T_CS, T_RD, T_ADS, T_ADH, T_WDS, T_WDH). Added
Exar’s UART Technical Support E-mail address to first and last page.
