NOTES

: (Notes apply to all specifications)

1. QBD (Quasi-bidirectional) pins include Port 1, P2.6 and P2.7.

2. Standard Outputs include AD0±15, RD,WR, ALE, BHE, INST, HSO pins, PWM/P2.5, CLKOUT, RESET, Ports 3 and 4,

TXD/P2.0 and RXD (in serial mode 0). The VOH specification is not valid for RESET. Ports 3 and 4 are open-drain outputs.

3. Standard Inputs include HSI pins, EA, READY, BUSWIDTH, NMI, RXD/P2.1, EXTINT/P2.2, T2CLK/P2.3 and T2RST/

P2.4.

4. Maximum current per pin must be externally limited to the following values if VOL is held above 0.45V or VOH is held

below VCC b 0.7V:

IOL on Output pins: 10 mA

IOH on quasi-bidirectional pins: self limiting

IOH on Standard Output pins: 10 mA

5. Maximum current per bus pin (data and control) during normal operation is g3.2 mA.

6. During normal (non-transient) conditions the following total current limits apply:

Port 1, P2.6

IOL:29mA

IOH is self limiting

HSO, P2.0, RXD, RESET IOL:29mA

IOH:26mA

P2.5, P2.7, WR, BHE

IOL:13mA

IOH:11mA

AD0±AD15

IOL:52mA

IOH:52mA

RD, ALE, INST±CLKOUT IOL:13mA

IOH:13mA

7. Typicals are based on a limited number of samples and are not guaranteed. The values listed are at room temperature

and VREF e VCC e 5V.

ICC Max e 3.88 c FREQ a 8.43
