P87LPC769 NXP Semiconductors, P87LPC769 Datasheet - Page 57

• Manufacturer Part Number: P87LPC769
• Description: The P87LPC769 is a 20-pin single-chip microcontroller designed forlow pin count applications demanding high-integration, low costsolutions over a wide range of performance requirements
• Manufacturer: NXP Semiconductors

1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for all outputs = 80 pF.
3. Parts are guaranteed to operate down to 0 Hz.
4. Applies only to an external clock source, not when a crystal is connected to the X1 and X2 pins.
