AC TESTING INPUT OUTPUT WAVEFORMS

270501 – 17

AC Inputs during testing are driven at VCCb05V for a Logic ‘‘1’’

and 045V for a Logic ‘‘0’’ Timing measurements are made at VIH

min for a Logic ‘‘1’’ and VOL max for a Logic ‘‘0’’

FLOAT WAVEFORMS

270501 – 18

For timing purposes a port pin is no longer floating when a

100 mV change from load voltage occurs and begins to float

when a 100 mV change from the loaded VOH VOL level occurs

IOL IOH t g20 mA This is for Ports 1 2 and 3

DATASHEET REVISION HISTORY

The following are key differences between this datasheet and the -006 version

1 The ‘‘preliminary’’ status was dropped and replaced with production status (no label)

2 Trademarks were updated

The following are key differences between the -006 and the -005 version of the datasheet

1 Preliminary notice has been added to the Title page

2 Figure 3 Pin Connections has been modified RST pin is now RESET pin

3 RST pin description is now RESET pin description

4 Figure 6 ICC vs Frequency has been corrected to show test conditions

5 ICC Max spec has been corrected

6 AC Characteristic table 1TCLCL spec has been changed to have a Max frequency of 16 MHz

The following are key differences between the -005 and the -004 version of the datasheet

1 ‘‘NC’’ pin labels changed to ‘‘Reserved’’ in Figure 3

2 Capacitor value for ceramic resonators deleted in Figure 4

The following are the key differences between the -003 version of the 8XC51FA datasheet and the -004

version of the 80C51FA83C51FA datasheet

1 Removed references to EPROM from the 8XC51FA datasheet

2 Revised Figure 4 ‘‘Oscillator Connections’’

The following are the key differences between the -002 and the -003 version of this datasheet

1 Dropped word ‘‘maximum’’ from IOL in the Absolute Maximum Rating table

2 Dropped EA from ILI specification of the DC table

3 Corrected TQVWH specification (from TTCLCL b 70 to TCLCL b 150)

4 Added note on external clock capacitance loading

5 Changed the title to 80C51FA83C51FA Event-Control CHMOS Single-Chip 8-Bit Microcontroller

6 Added pin count to Figure 1

7 Changed ILI to g10 mA

8 Added ICC Power Down Mode 150 nA
