Preliminary specification
83C749/87C749
80C51 8-bit microcontroller family
2K/64 OTP/ROM, 5 channel 8-bit A/D, PWM, low pin count
1998 Apr 23

may always be used as digital inputs. Unselected analog inputs will
be floating and may not be used as digital outputs.
The A/D reference inputs on the 8XC749 are tied together with the
analog supply pins AV
CC
and AV
SS
. This means that the reference
voltage on the A/D cannot be varied separately from the analog
supply pins. AV
SS
must be connected to 0V and AV
CC
must be
connected to a supply voltage between 4.5V and 5.5V. A/D
measurements may be made in the range of 4.5V to 5.5V.
Increasing the voltage on the A/D ground reference above 0V or
reducing the voltage on the positive A/D reference below 4.5V is not
permitted.
