• Manufacturer Part Number: MC68HC908QY2
• Description: Microcontrollers
• Manufacturer: MOTOROLA [Motorola, Inc]

1. V
2. Typical values reflect average measurements at midpoint of voltage range, 25°C only.
3. Run (operating) I
4. Wait I
5. All ports configured as inputs. All ports driven 0.2 V or less from rail. No dc loads. On the 8-pin versions, port B is configured
6. Maximum is highest voltage that POR is guaranteed.
7. If minimum V
8. R
18.7 5-V Control Timing
1. V
2. Some modules may require a minimum frequency greater than dc for proper operation; see appropriate table for this
3. Minimum pulse width reset is guaranteed to be recognized. It is possible for a smaller pulse width to cause a reset.
