AT90S/LS8535
1041H–11/01
Notes: 1. “Max” means the highest value where the pin is guaranteed to be read as low (logical “0”).
2. “Min” means the lowest value where the pin is guaranteed to be read as high (logical “1”).
3. Although each I/O port can sink more than the test conditions (20 mA at V
CC
= 5V, 10 mA at V
CC
= 3V) under steady state
conditions (non-transient), the following must be observed:
PDIP Package:
1] The sum of all I
OL
, for all ports, should not exceed 200 mA.
2] The sum of all I
OL
, for port A0 - A7, should not exceed 100 mA.
3] The sum of all I
OL
, for ports B0 - B7, C0 - C7, D0 - D7 and XTAL2, should not exceed 100 mA.
PLCC and TQFP Packages:
1] The sum of all I
OL
, for all ports, should not exceed 400 mA.
2] The sum of all I
OL
, for ports A0 - A7, should not exceed 100 mA.
3] The sum of all I
OL
, for ports B0 - B3, should not exceed 100 mA.
4] The sum of all I
OL
, for ports B4 - B7, should not exceed 100 mA.
5] The sum of all I
OL
, for ports C0 - C3, should not exceed 100 mA.
6] The sum of all I
OL
, for ports C4 - C7, should not exceed 100 mA.
7] The sum of all I
OL
, for ports D0 - D3 and XTAL2, should not exceed 100 mA.
8] The sum of all I
OL
, for ports D4 - D7, should not exceed 100 mA.
If I
OL
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
4. Although each I/O port can source more than the test conditions (3 mA at V
CC
= 5V, 1.5 mA at V
CC
= 3V) under steady state
conditions (non-transient), the following must be observed:
PDIP Package:
1] The sum of all I
OH
, for all ports, should not exceed 200 mA.
2] The sum of all I
OH
, for port A0 - A7, should not exceed 100 mA.
3] The sum of all I
OH
, for ports B0 - B7, C0 - C7, D0 - D7 and XTAL2, should not exceed 100 mA.
PLCC and TQFP Packages:
1] The sum of all I
OH
, for all ports, should not exceed 400 mA.
2] The sum of all I
OH
, for ports A0 - A7, should not exceed 100 mA.
3] The sum of all I
OH
, for ports B0 - B3, should not exceed 100 mA.
4] The sum of all I
OH
, for ports B4 - B7, should not exceed 100 mA.
5] The sum of all I
OH
, for ports C0 - C3, should not exceed 100 mA.
6] The sum of all I
OH
, for ports C4 - C7, should not exceed 100 mA.
7] The sum of all I
OH
, for ports D0 - D3 and XTAL2, should not exceed 100 mA.
8] The sum of all I
OH
, for ports D4 - D7, should not exceed 100 mA.
If I
OH
exceeds the test condition, V
OH
may exceed the related specification. Pins are not guaranteed to source current
greater than the listed test condition.
