c
Operating Temperature..................................–55°C to +150°C Note: Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the

operation of the device at these or any other condi-
tions beyond those indicated in the operational 
sections of this specification is not implied. Exposure 
to absolute maximum rating conditions for extended

1.3 Maximum Speed vs. VCC

Maximum frequency is dependent on VCC. As shown in Figure 1-1, the Maximum Frequency

vs. VCC curve is linear between 1.8V < VCC < 3.6V.

Notes: 1. “Max” means the highest value where the pin is guaranteed to be read as low

2. “Min” means the lowest value where the pin is guaranteed to be read as high

3. Although each I/O port can sink more than the test conditions (0.5 mA at VCC = 1.8V) under steady state conditions

(non-transient), the following must be observed:

1] The sum of all IOL, for ports B0 - B5, should not exceed 50 mA.

If IOL exceeds the test condition, VOL 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 (0.5 mA at Vcc = 1.8V) under steady state conditions

(non-transient), the following must be observed:

1] The sum of all IOH, for ports B0 - B5 should not exceed 50 mA.

If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current

greater than the listed test condition.
