AC TESTING INPUT OUTPUT WAVEFORMS
AUTOMOTIVE 80C51FA 83C51FA
FLOAT WAVEFORMS
270501 – 17
AC Inputs during testing are driven at V_CCb0 5V for a Logic ‘‘1’’
and 0 45V for a Logic ‘‘0’’ Timing measurements are made at V_IH
min for a Logic ‘‘1’’ and V_OL max for a Logic ‘‘0’’
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 V_OH V_OL level occurs
I_OL I_OH 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 I_CC vs Frequency has been corrected to show test conditions
5 I_CC Max spec has been corrected
6 A C Characteristic table 1 T_CLCL 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 80C51FA 83C51FA 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 I_OL in the Absolute Maximum Rating table
2 Dropped EA from I_LI 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 80C51FA 83C51FA Event-Control CHMOS Single-Chip 8-Bit Microcontroller
6 Added pin count to Figure 1
7 Changed I_LI to g10 mA
8 Added I_CC Power Down Mode 150 nA
